It's not as simple as that.
In my view Qt went backwards with the version 6 release and QML support on
the desktop.
What was there before (Controls V1) in Qt5 sure had it's fair share of
bugs, true, but it was working very stable with relatively minor annoyances
to work around.
One should not remove something if the replacement isn't at least
reasonable on par with what was removed. I'm sure some of it is driven by
the maintenance cost of 2 component sets so with that in mind it did make
much sense to drop one. That being said, I don't think the current
components should be more than a labs project.

That's good to hear :)
I do still care enough to want to use Qt with QML if it gets better.

That sounds like a rough time and a developer nightmare.
While I don't have that experience (porting from QWidgets to QML), I do
have the experience from QML (Qt 5.x) with Controls V1 to Controls V2 in Qt
6.
The experience there is that components with the same names - making you
think you can easily port - have wildly different properties and in general
work just completely different.

Another annoyance are the component defaults. Those defaults are definitely
not suitable for desktop usage. Properties like selecting text or even
being able to edit it are off by default.
Need mouse support to select text?... You might or might not be able to
enable it. For a TextField you can enable it. For a SpinBox you can't
enable it at all. And there's so much more like this.

But... I thought one of the big selling points for QML was - when it first
got introduced - that it had live updating capabilities.
I never used it but I thought it was a unique selling point.

Well, it was nearly good enough in the Qt5 days with Controls V1.
All they needed was a better set of controls to accommodate mobile more and
reduce complexity in V1.

What they did - conceptually - with V2 was good.
But it seems like they just left it in alpha quality and call it "ok" to
replace V1.. That was a mistake.
It needed much more development time to be a proper replacement.

We're now like ~8 years past the introduction of the V2 set...
And it still has really severe bugs that just interrupt usability. 8
years...
So I doubt it will be getting any better at all.

Hi Robert,

Thank you for your reply!
I'm well aware of Widgets and it's looks, I've got quite some years of
experience with them:)

In fact, there's a "funny" thing with Qt here.
There is a QML component gallery [1] meant to demonstrate the components.
1. The compilation of that project takes _longer_ than the QWidgets gallery
demo [2]
2. You need to restart the QML gallery for theme changes where they are
right there on the fly in QWidgets.

Having said that...
The development speed and debugging is in fact faster in QML. It's also
much easier to change quite significant parts with relative ease.
Therefore I'd still like to go for QML.

But the components Qt provides are so bad that it's essentially impossible.
Hence I'm looking for components that integrate nicely in the platform.

Should I just consider QML to be dead[3] on the desktop now?

[1]
https://code.qt.io/cgit/qt/qtdeclarative.git/tree/examples/quickcontrols2/gallery
[2] https://code.qt.io/cgit/qt/qtbase.git/tree/examples/widgets/gallery
[3] As in when going for platform integration. If you go the full custom
route you're fine.

[Interest] Is there a good alternative to the QML Controls in Qt6 for native desktop integration purposes?

[Mark Gaiser]

Hi,

I'm facing so many bugs in QML Controls in Qt6 (they used to be Controls V2
in the Qt 5.x days) that I don't want to use them at all anymore. They are
bugged beyond repair and downright unusable for native desktop integration
purposes.

Is there another good open source component set out there that integrates
with the desktop. Specifically with Windows but preferably also with Linux
(kde and gnome) and Mac.

Using QWidgets should not be an alternative as it slows down development a
lot. But given the crap that QML Controls is makes me consider switching to
QWidgets instead.

I'm surprised because the code where i used this uses QtQuick.Controls 1

[Interest] Does QML have a way to detect if a click is outside an element?

[Mark Gaiser]

Hi,

Picture a QML window with a red rectangle in the middle of it (say 200x200
px).
The window itself is, say, 500x500 px.

Now I'm looking for a way to detect when you click on any area outside the
red rectangle but inside the white window area.

The reason I need this is to provide a more intuitive interaction. In my
particular case the red rectangle is a calendar popup that needs to go away
when you click outside of it but inside the window still.

I can imagine 2 possible solutions, both are quite cumbersome to implement.

1. One can make a kind of "EventFilter" object in C++ and expose it to QML.
So that custom event filters can be made which would allow me to find a
click that occurs outside the rectangle.

2. I can make an application with overlapping MouseArea{} and figure it out
that way. But this is really hacky and very error prone.

Does QML provide another more native way for this kind of interaction?

[Interest] Recording video on Windows

[Mark McKay]

After doing a lot of testing trying to get Qt Multimedia related
classes working in a Windows environment, I came across this:


https://doc.qt.io/qt-5/qtmultimedia-windows.html [1] 

This was
referenced by a newsgroup post from 2014 so presumably it's been an
issue for a while. 

I'm writing a program where I would like to create
a video by generating original audio and video data. I was considering
using the Qt Mulitmedia classes to avoid having to use third party
libraries, but they appear not to be implemented on Windows.

Are there
any plans to get Qt Multimedia working on Windows so it can be a
cross-platform solution?

[Interest] How to properly translate an application?

[Mark Gaiser]

Hi,

I have a windows desktop application (Qt 5.9 LTS) here that has Dutch and
English translations files (in .ts format) created with Qt Linguist. Any
strings in that file show up in the Qt UI just fine in the chosen language.

But if i set the language to Dutch (operating system language is English)
then Qt's default buttons are still in English. Sure, they can be
translated on a case-by-case basis but i don't think that
should be needed.

I don't think there is a problem with the .ts files as anything in there
just works in the UI.
But perhaps i missed a step?

The translation files are generated as follows:

lupdate -verbosr file.pro

"file.pro" contians the required translation lines:
TRANSLATIONS += dutch_nl.ts
TRANSLATIONS += english_en.ts

Run some benchmarks and you'll see :)
If you want i can search for my old benchmark code. It surely is somewhere,
i just need to find it.

That is not true!

I had benchmarked this years ago and using QCollator directly is _always_
the slowest path.
I had a whole blogpost about that, but that blog went offline... The code
is still somewhere, but i'm very sure that using QCollator directly is
never the fastest path in terms of performance, not even for a few entries.
In terms of ease of use it is the easiest one :)

Re: [Interest] How to make the QString "10" behind "9" in QMap's key order

[Mark Gaiser]

Hi,

That is tricky!

Disclaimer: The example below is just for illustration purposes. It's not
complete and will not work! It only gives you the general idea of a
possible solution.

This basically boils down to maintaining more lists.
for instance:

std::vector source;
std::vector keyCache;

You want to sort "keyCache" and update "source" in the same order.
There are a couple of ways of achieving this.

An approach i did years ago did the exact opposite of what i just
suggested. I added a proxy index on top like:
std::vector proxyToKey;

I sorted the proxyToKey mapping like so:
std::sort(proxyToKey.begin(), proxyToKey.end(), [&](int a, int
b) {
return m_collator.compare(keyCache[a], keyCache[b]) < 0;
});

Now your source[proxyToKey[0]] is the first entry.
This however is quite tricky to get right as you have to keep track of your
bookkeeping (aka, update the collator keyCache, source and proxy for every
change).

Another approach i learned later was by means of a so called "zip
iterator". Boost has one but it's not mutable so you can't sort.
There are other zip iterators out there that do work with std::sort and
those are imho the best solution with the least amount of added bookkeeping.

Another even better approach (but that's not possible at the moment) would
be a QCollatorSortKey to also act as QString itself so that your sort key
is also your string. All string data is known in that key, but the layout
is different. That is something for the future i hope.

Hi,

You might want to look into std::map[1] as well. It allows setting a
compare function, QMap doesn't.
Going that route is most likely more efficient as your inserts will be
sorted, no need to do std::sort afterwards.

You still would have to use QCollator. Note that you can just use QCollator
in the compare method which will work just fine, but is not the performant
way to go.
The most performant way (i know of) is by using QCollatorSortKey[2].

That looks like a really powerful "cURL for QML" api heavily inspired on
Javascript Promises.

I wouldn't use that directly in QML (it looks too low level for QML...) but
it can serve as base to implement some fancy models.
Thank you for that link!

Well, in my ideal situation the web request fills a model which is then
hooked into a view.
An hypothetical API like:

WebRequestModel {
  id: webRequest
  url: "https://some/webservice/url;
  parseType: WebRequestModel.JSON
}

ListView {
  model: webRequest
  .. and some delegate stuff ..
}

Done :)
That would look really clean to me and be very powerful for QML. I'm
slightly surprised that QML doesn't have something like this yet.

A little explanation for the hypothetical "WebRequestModel". As i wrote it
above it should have multiple ways to parse it's data. JSON in this case,
but also XML and YAML at the very least.
The QML -> C++ passing would just be the url from the QML side to the C++
QAIM implementation. There the JSON (and other types) would be parsed.
This structure would only work with simple data outputs from web services.
Not if there is cruft around the data that you'd need to filter out first.
You could add a hypothetical property to the hypothetical WebRequestModel
called "path" or "xpath" which would define the part of the data to use for
the model.

As for not liking XMLHttpRequest. It works I just don't like it's API.
It looks very verbose and very specific for website backends. Not really
fitting (api wise) for QML.
Did i answer all your questions? :)

[Interest] Is there a QML way for doing web requests? Just for data, not for rendering.

[Mark Gaiser]

Hi,

You know those fancy REST api's out there.
How does one use them in QML?

For websockets the answer is simple: QML WebSocket.
But i didn't find a way to just do a web request to some url and get it's
data, at least not a way that seems "QMLified".

Sure, javascript can be used with it's XMLHttpRequest which will work just
fine, but using it seems so.. not QML like. So is there a QML way to do
such things?

Re: [Interest] Awkward Javascript problem

[Mark Tucker]

Hi Nuno,

Are you attempting to access this "controller" property within a 
"Component.onCompleted" block of code?

With Loaders I've found from experience that there's a brief period of time 
where the component has been created (and therefore its Component.onCompleted 
signal fires), but it has not yet been fully added to the object heirarchy, so 
attempting to access anything outside of that object's own scope fails.

The only way I've ever found to get around this limitation is to instead figure 
out a way of using the onLoaded signal from the Loader, which seems to be 
emitted at a point where the QML object is correctly placed within the object 
heirarchy and can actually correctly access things outside of its own scope.

The above is my own observations from a number of years of writing QML code - 
it may be what you're seeing here. I don't know anywhere near enough about how 
the C++ side of things or how the internals of Qt works to be able to provide 
any more detail.

Perhaps you can change the point at which you run this code?

Subject: [Interest] Awkward Javascript problem

Hi,

I usually register a controller property that points to a Controller classe 
when I start my Qt apps. I can then access the controller from any point of the 
code in Javascript:

quickView->rootContext()->setContextProperty("controller", );

Curiously, I’m having an issue in which inside a MouseArea onClick event, 
controller is not defined:

ReferenceError: controller is not defined

This MouseArea lives inside a Loader component that is one of the children of a 
SplitView.

Maybe this be the cause for such ReferenceError? How can I workaround this? Any 
ideas?

Thanks!

Nuno

Re: [Interest] Improve ListView scrolling performance (many pictures)

Hi,

I don't quite follow.

First you say you implemented our suggestions (move image processing in a
thread), then you say: "all operations are performed in the main (GUI)
thread"... Exactly the opposite of what we've been suggesting.

If i'm reading your reply correctly you're not offloading anything to a
separate thread ;)
Do that and the listview will feel a lot more performant.

Re: [Interest] Improve ListView scrolling performance (many pictures)

[Mark Gaiser]

You need to do the "heavy" image operations in a separate thread!
Copy the result back to the main thread and feed it to QML.
You should not do any more operations on it once it lives in the main
thread (no resize, scale, colorize, whatever) as you will notice that
during scrolling.

[Interest] Android 5.9.1 qmltestcase

[Mark R Youngquist]

I've been struggling for a bit without an understanding of why this error is 
occuring.  We have a series of test cases we want to run on Android, but are 
unable to get a build to compile.  This works properly under 5.8.0, and it 
works on Windows builds with 5.9.1


We simple add a CONFIG+=qmltestcase to the project pro file, and begin getting 
a series of errors during the qmake process:


Makefile:1954: warning: overriding recipe for target 'install_target'

Makefile:1945: warning: ignoring old recipe for target 'install_target'

Makefile:1958: warning: overriding recipe for target 'uninstall_target'

Makefile:1949: warning: ignoring old recipe for target 'uninstall_target'


Additionally if we attempt to build while ignoring those warnings we get errors 
within mingw.


Is there something I am missing?  Documentation is not helping as it doesn't 
look like anything has changed with regards to testing.


Thanks!

Re: [Interest] Updating NumberAnimation from/to at runtime

[Mark Tucker]

From my experience, once started, you cannot dynamically change the parameters 
(such as from, to, duration) of an animation in such a way, without restarting 
the animation. Doing so simply has no effect on the already running animation.

In other words, the values are taken as an assignment at the point at which 
it's started and will not change until the animation is restarted.

Hi,
Consider the following code which draws two rectangles - a red rectangle which 
contains another blue rectangle.

Rectangle {
id: r1
anchors.centerIn: parent
width: 300; height: 100
color: "red"

Rectangle {
id: r2
width: 100; height: 100
color: "blue"

NumberAnimation on x {
loops: Animation.Infinite
from: 0; to: r1.width-r2.width
duration: 1000

onToChanged: console.log(to)
}
}

NumberAnimation on width {
loops: Animation.Infinite
from: 300; to: 100
duration: 1
}
}
The blue rectangle is supposed to keep moving inside the red rectangle by means 
of a NumberAnimation. However, the width of the red rectangle changes according 
to another animation.
I thought this will work fine and the blue rectangle will be confined to the 
red rectangle because of the following binding-

to: r1.width-r2.width
However, thats not what happens. The blue rectangle overflows the red 
rectangle, as if the binding never got updated. But, I can see that the 
`console.log(to)` does prove the binding is working.

Is this a limitation of NumberAnimation? Or am I using it wrong?

Or is it all still in a planning phase?

Anyhow, if there is some working code for this somewhere, could you point
me to that? I'd like to play with it and see if it fits my needs.
In this case that's merely displaying a calendar and showing animations
when switching between months.

Hello Everyone,

I am trying to use SwipeView and ComboBoxStyle together in a file. In 
QtQuick.Controls 2.1, seems like style properties is not there.

I tried to mix both modules. I believe we shouldn't do this.
But when I experimented this approach to use SwipeView and ComboboxStyle 
together.
Please refer to the snippets below.

In first case, QtQuick.Controls 2.1 is used before 1.4. Hence it works properly.
In second case, QtQuick.Controls 1.4 is used before 2.1 and it gives error.
In third case, I mixed and accessed with another name and it fails again.

Is it a bug in ComboBox implementation in QtQuick.Controls 2.1? How can I use 
both SwipeView and ComboBoxStyle together?

Snippet 1: //Works

This sadly isn't the case.hat might not be entirely correct anymore.
It used to be a platform plugin that you could load in any desktop environment.

But this changed some half year ago [1] since they had issues they
"could not resolve otherwise"...
The platform theme is now part of some plasma library or kwin. Don't know.

That doesn't mean it doesn't work. It's just not guaranteed to work
and if it does, it will lack support for some features. I think it was
about the system tray, but i don't know the details.

Re: [Interest] QML WebView modules

[Mark Tucker]

Ah, there's a 5.5.1 tag in there, presumably that's what I would need?

Now I need to read up on how to use this from git :)

Thanks

Re: [Interest] QML WebView modules

[Mark Tucker]

I'm not using the SDK installer - I compiled my own version of Qt from the 
5.5.1 sources. There doesn't seem to be anything included in that tarball that 
is the QtWebView module.

Is it a separate download?

Re: [Interest] QML WebView modules

[Mark Tucker]

Hi Kai,

My problem is that despite having successfully compiled and installed both the 
qtwebkit and qtwebengine modules for Qt 5.5.1 on my desktop Linux platform, the 
QML statement

import QtWebView 1.0

Reports as being uninstalled/not available when I attempt to run my QML app on 
my Linux platform. (Note that using 1.1 instead of 1.0 produces the same 
effect). This import works on my target Android platform.

There does not appear to be a specific "qtwebview" folder/module within my Src 
folder for my Qt version.

I ran configure with no options, i.e. literally just "./configure" with nothing 
added.

I can live with having to have different import statements for the different 
platforms if I have to, was just wanting to check that I wasn't missing 
something stupid/obvious.

Thanks

Mark

Not exactly. The terminology is arguably confusing here, but the "QtWebView" 
import comes from the "Qt WebView" module 
(http://doc.qt.io/qt-5/qtwebview-index.html), which is a module that abstracts 
different rendering engines (Qt WebEngine, native) away behind a simple API.

So 

---
import QtWebView 1.0

WebView {
  // ...
}
--
should work both on mobile and desktop. On Android, iOS and WinRT the native 
browsers are embedded, on all the rest Qt WebEngine is used (if available).

Re: [Interest] QML WebView modules

[Mark Tucker]

Hi All,

Thanks for your input.

Seems like due to the Qt version I need to use, I may have to have different 
QML code for my target Android and Linux platforms.

I have ways of working around this, and this isn't for anything that's going 
public anyway so I'll figure something out.

Thanks again!

Subject: Re: [Interest] QML WebView modules

Dear Sze-Howe,

I haven't worked much in Qt web modules. But below is my understanding.

With Qt 5.5 the Qt WebKit module is 
deprecated:(https://wiki.qt.io/New-Features-in-Qt-5.5#Deprecated_Functionality)

QWebView uses WebKit as the backend.

QWebEngineView uses Chromium as the backend.

WebView with the same name has been defined in both WebKit and WebEngine. Hence 
import statement varies.[I believe this is the source of confusion ]

import QtWebKit 3.0
import QtWebView 1.0

In 5.8,
import QtWebView 1.1
QT += qml quick webview
This is useful on mobile platforms such as Android, iOS, and WinRT; especially 
on iOS, where policy dictates that all web content is displayed using the 
operating system's web view. [ http://doc.qt.io/qt-5/qtwebview-index.html ]

Nibedit

The Qt WebView module is not related to WebKit.

Unfortunately, there are two different things named "WebView" in Qt,
which is very confusing:

* http://doc.qt.io/archives/qt-5.5/qml-qtwebview-webview.html
* http://doc.qt.io/archives/qt-5.5/qml-qtwebkit-webview.html

When Qt WebView first started as a Tech Preview in Qt 5.4, it only
supported Android and iOS. These platforms were chosen specifically
because Qt WebKit and Qt WebEngine can't run on them.

In later releases, support for desktop platforms was added to Qt
WebView, but I'm not exactly sure which version. Qt 5.5 might be too
early.

[Interest] QML WebView modules

[Mark Tucker]

Hi,

I'm currently trying to create a QML app that works on both a Linux platform 
and an Android platform. Due to the nature of my target platforms (embedded 
systems), I'm limited to Qt 5.5.1 and cannot upgrade.

Note that my app is pure QML and I cannot write any C++ code to solve this.

To get the app running on Android, I can put "import QtWebView 1.1" into my QML 
file imports, and then create a simple WebView component and set its URL and 
that works.

That same import doesn't work for me on Linux, however. I can use either 
"import QtWebKit 3.0" or "import QtWebEngine 1.1" (with the latter, changing my 
WebView to a WebEngineView too) and I can then see a webview that works with no 
issues, but neither of those are available on my Android target (nor, from what 
I understand, will they ever be).

So, is there a way I can get the QtWebView import working on Linux? I can't 
seem to figure out how to build it, or if it's even a valid option.

If not, then I guess that means I'll need to have different QML for both Linux 
and Android...

Thanks in advance

Mark

Kai:

Thank you for the response.

As a QT customer, I would hope that communications from Qt Staff would
yield something that I can USE.

Your response suggested that dependency build failures are an uncommon
occurrence. ("there might still be feature permutations that lead to
compilation errors")

I can assure you that 100% of my attempts to reduce the binary size of
Qt 5.8 have ended in failure.

Don't believe me?  Try this test config line:

/macdev/qt580/5.8/Src/configure -prefix /macdev/qt580/5.8/osxstat \
-verbose \
-opensource \
-release \
-strip \

[Interest] Qt Lite 5.8

[mark diener]

Tor:

In the 5.8 release blog, on January 24, 2017 at 14:40,  you said:

"Stay tuned for some more info on this in the coming week."

The week has almost expired.

Really want some configure examples to actually realize the benefits of Qt Lite.

After spending about 4 hours last Friday, I could not figure out how
to build a "Lite" anything.

The only thing I could build is the full build rocking out at 30 MB on OSX.

But anytime I tried to "reduce" binary size, the build would fail with
some dependency vomiting errors.

What I really want is to get IOS and Android build size down according
to Lars compelling build size graph from the blog.

So we need those minimal samples and some way to navigate the
dependencies without this process
becoming another full time job for us.

Re: [Interest] 5.8.0 QAbstractListModel

[mark diener]

Bill:

I thought I would do a brain dump on what I learned.

If your data is bound by the roleNames() mechanism, then the
dataChanged( ) function works greatl

If your data is retrieved by INVOKABLE functions, then you need to call
the following:

QModelIndex gi = QModelIndex() ;
beginInsertRows(gi,gnrow,gnrow);
endInsertRows();
beginRemoveRows(gi,gnrow,gnrow);
endRemoveRows();

This will force the listview to drop and re-create the component in
the delegate.

Thanks for your feedback.

Marco

[Interest] 5.8.0 QAbstractListModel

[mark diener]

Cannot use emit dataChanged(index(0),index(growcount-1)) to cause
re-display of changed
values in ListView.

Tried every combination:

emit dataChanged(index(grow),index(grow));
emit dataChanged(index(0),index(grows));
emit dataChanged(index(0),index(grows-1));

Only can repaint entire ListView with:

this->beginResetModel();
this->endResetModel();

But this is overkill,. I want to trigger the Model to update a single
row.

Anyone with ideas?

[Interest] Fonts Puking on Qt 5.7.1:

Just run the following QML on iphone, android, and OSX and you will
see the great
QML Font Mystery.

All devices set to display English language.

On OSX 10.11.5 -> there are 2 different weights
On Ipad 2 running IOS 9.3.2-> there are 2 different font weights.
On Ipad Mini V1 running IOS 9.3.2-> there are 2 different font weights.
On Nexus 7 2013, Android 5.1.1-> there are 4 different font weights.
On Motorola G 2014 -> there are 4 different font weights

On Iphone 6, running 9.3.2, there is only 1 SINGLE font weight.  There
is no BOLD text available.

Maybe this link works for public users:

[Interest] TextInput Vs TextEdit

[mark diener]

Using Qt 5.7.1 on OSX and building for Android,

import QtQuick 2.7
import QtQuick.Controls 1.5

For TextInput, I receive Key.OnPressed for standard keys like A->Z,1-9, etc.

But for TextEdit, No events at all except for control keys like enter,
escape, backspace.

When I run the same code on OSX, I get the key events.  Debugging for
IOS is another matter.

Anybody have an idea on why TextInput receives keys while TextEdit has
a reduced set.

[Interest] Copy QSqlRecord to different database

[Mark Gaiser]

Hi,

Imagine this case:

You fetch data from one database (say MariaDB), you get a QSqlQuery filled
with QSqlRecords.
Now i want to copy all those records to another QSqlDatabase instance this
is an SQLite database.

The SQLite database has some fields with different names compared to the
MariaDB one, but that is easily fixable by changing the field name (using
setName on an individual QSqlField).

What i don't know is how to proceed from there on.
Would it be enough to call setDatabase on the original query by setting it
to the destination database? Then i'd probably have to change the query to
be an update or insert query?

Would that work?
Does anyone have any experience in copying data from one database to
another using Qt?

Cheers,
Mark

Thank you for the clear options.
I was hoping for some magic compile flag to fix this on MSVC 2010, but
apparently i'm out of luck.

The only option i seem to have left for 2010 are apparently:
- Making sure the source files are UTF-8 formatted (most is ascii at the
moment)
- Using tr("Coördinaat"); as opposed to tr("Co\u00F6rdinaat");, that does
work, but is not preferred.

[Interest] Unicode code points in Vusual Studio. Output differs from MinGW

[Mark Gaiser]

Hi,

The following minimal code example demonstrates the issue (tested on Qt
5.6.1):

#include 
#include 
#include 

int main(int, char **)
{
  qDebug() << "tr:" << QObject::tr("Co\u00F6rdinaat");
  qDebug() << "QString:" << QString("Co\u00F6rdinaat");
  qDebug() << "(QDebug) std::string:" <<
QString::fromStdString(std::string("Co\u00F6rdinaat"));
  std::cout << "(cout) std::string: " << std::string("Co\u00F6rdinaat") <<
std::endl;

  return 0;
}

Here all the qDebug lines output "Co?rdinaat". The cout line outputs
"Coördinaat" as i would expect.
If i use visual studio (both 2010 and 2015) for the above example, only the
std::cout gives the output i'd expect (which is "Coördinaat").
If i use mingw the exact opposite is the result. All qDebug lines output
"Coördinaat", but the cout line outputs as "Coördinaat"

QStringLiteral("Co\u00F6rdinaat") works on MSVC (2010 and 2015) as well as
MinGW. But for my case that fix isn't working because the string must be
within tr(...) and that function doesn't accept a QStringLiteral.

Is there any way that i can use a string with unicode code points within
tr(...) that works on MSVC 2010 (as that is my setup), but it would be
great if it also works under MSVC 2015 and MinGW.

Best regards,
Mark

binary release [1]. It starts with Visual Studio 2013 in that folder.

Is Qt not providing a 2010 build anymore?

Best regards,
Mark

Ah great, you found the real issue: Plasma :)
now you could try the same on plasma again only with kwin killed.

If that fixes your issue then you know for sure that kwin is doing
something you don't want and are probably best off by describing a minimal
case that kwin breaks and post that in the plasma development mailing list (
plasma-de...@kde.org) to further nail down the issue.

Install openbox on your system en logon (via sddm) in an openbox session.
Then try your app and see if it works.

If that does work then plasma is probably taking that global shortcut. If
it doesn't then the issue is quite a bit deeper.

[Interest] PRO File defines

[mark diener]

Hello List:

Who can tell me how to detect whether a build is for IOS or IOS Simulator
in the project PRO file.

ios {
QMAKE_IOS_DEPLOYMENT_TARGET=8.0
QMAKE_IOS_TARGETED_DEVICE_FAMILY=1,2
}

But how to I differentiate between IOS builds and IOS-simulator builds?

[Interest] TextField Focus onReleased

[mark diener]

Hello:

Can anybody figure out a way for a TextField which contains its own MouseArea
to allow the TextField to gain focus when the onReleased event is
called, not the normal behavior of focus gained when the onPressed is
triggered.

Any response appreciated,

Re: [Interest] Exposing nested visual properties in FocusScope (alias -> alias problem)

[Mark Tucker]

Hello,

As long as your internal Text item has an id, then you can add the aliases in 
the FocusScope. This should work:

FocusScope {
property alias text: text.text
property alias textPixelSize: text.font.pixelSize

Rectangle {
id: button
focus: true

width: text.implicitWidth
height: text.implicitHeight

Text {
id: text
...
}
}
}

Subject: [Interest] Exposing nested visual properties in FocusScope (alias -> 
alias problem)

Hi all,

I'm trying to create a reusable component for a button. Right now I'm trying to 
figure out focus handling (the app is keyboard navigation only).

I currently have the following structure (Button.qml):

Rectangle {
id: button

property alias text: text.text
property alias textPixelSize: text.font.pixelSize

width: text.implicitWidth
height: text.implicitHeight

Text {
id: text
...
}
}

Where I'm exposing the text and pixelSize properties of the text by using 
property aliases, to be able to use it like:

Button {
text: "Foo bar"
textPixelSize: 42
}

This works fine. But now I'd like the component to be able to participate in 
focus handling, so I wrap it in a FocusScope, e.g:

FocusScope {
Rectangle {
id: button
focus: true

property alias text: text.text
property alias textPixelSize: text.font.pixelSize

width: text.implicitWidth
height: text.implicitHeight

Text {
id: text
...
}
}
}

Which should allow me to use it in other nested focus scopes at a higher level 
in the visual tree

The problem now is that I must expose the button.text and button.textPixelSize 
in the FocusScope, to be able to use the component as before. But I can't use 
property aliases again, since a property alias may not refer to another 
property alias.

Anyone know how I can get around this?

Thanks in advance,
Elvis

Re: [Interest] How to hide keyboard while clicking outside of keyboard in qml

[mark diener]

Gianluca:

For simple QML layouts, I think your technique would work.

But I found that mousearea had issues when you had Loader objects in the chain.

Another approach is to use a Q_INVOKABLE function to register any QML
object that you want to have the keyboard hide whenever the touch
outside
of the registered QML Edit object.  I generally call this register
function for edit controls when they gain focus and use a common edit
control classname like "MyEdit"

Then in the overridden Application::eventproc(...), I look for
QEvent::TouchBegin or QEvent::MouseButtonPress event.

Then I use the incoming message's object metaObject() and parent() to
scan up the
parent chain to look for a object class name that matches my QML class
name "MyEdit"

Example: String(gobj->ClassName()).contains("MyEdit",Qt::CaseInsensitive")
== true

If I cannot find a match, I set the "focus" property of the registered
object "false".

You can also NOT hide the keyboard if the incoming mouse/touch message
is related to an object that is another "MyEdit" class.

I built this into a general library so now I don't even think about
it, I get fully functional soft keyboard hiding across all my apps and
it works.

Cheers,

md

[Interest] QML Keys Shock

[mark diener]

Hello List:

I went to deploy a test app on Android and IOS that would test processing
handling keys as they were entered into TextInput QML.

Shockingly, the Keys.onPressed is NOT called for normal letters on
either Android
or IOS.

Keys, like Back(delete) and Enter do trigger events, but forget about
implementing
PER keystroke logic on Android/IOS.

Some bug tracker dialogue between Eskil Abrahamsen Blomfeldt kind of
confirms this.

Maybe the documentation for QML Keys should be updated to let people
know that very FEW of the keys on the soft keyboard actually trigger
onPressed events.

Can someone tell me I am making a mistake and somehow ALL the keyboard
keys like letters and space are triggered on Android and IOS soft
keyboards  if I only make some manifest.xml or info.plist entry!

Cheers,

marco

Re: [Interest] [Development] 5.7 feature freeze

[mark diener]

Lars:

I am sure I am not the only newcomer to QT who would love to add code
to the 5.7 feature list,
but barely have time to contribute bugs to debug 5.6.0 beta let alone
look ahead to 5.7

Now we are faced with waiting until 5.8 to even think about a set of
key missing functions in Qt QML.

I am still firmly planted on the interest list and not on the development list.

One major problem lies with QQmlEngine design:

It has the following functions defined:

QQmlEngine->trimComponentCache()
QQmlEngine->clearComponentCache()  (https://bugreports.qt.io/browse/QTBUG-50500)

But it is absolutely missing:

QQmlEngine->addComponent("MyComponentLib",1,0,"MyComponentName",QQmlComponent&
gcomp) -> error code
QQmlEngine->removeComponent("MyComponentLib",1,0,"MyComponentName") ->
error code
QQmlEngine->isComponentLoaded("MyComponentLib",1,0,"MyComponentName") -> bool

Devs are stuck using a QMLDIR file based import pattern that has the
flexibility of an ice cube.

We really need qml files to be able to execute: import MyComponentLib
1.0 without using QMLDIR files!

The other major problem is that QQuickItem does not allow for
QSGTextRect, so updatePaintNode CANNOT have text rendering
in coordination with QSGGeometry.  The current recommendation is to
try to coordinate using signals between 2 different QQuickItems, 1
with text, the other
with graphical geometry.  This is a restriction that appears to have
occurred by chance.

This cripples custom controls capabilities and forces me to explain to
customers about Qt limitations.

So how can we get the header file for QQmlEngine changed for 5.7
feature freeze to add those 3 function declarations and un-sandbox
QSGTextRect
and still pass maintainer acceptance all by Monday?

Cheers,

md

Re: [Interest] TextField QML auto keyboard hiding/lose focus on touch events

[mark diener]

Gian:

Ok, I wanted to share my solution since you kindly offered a
suggestion a day or two ago.

1) Create an C++ function: Q_INVOKABLE void gregister(QObject* goedit) ;

2) Store the QObject away some where for access ONLY on the GUI thread.

3) For controls that I want to LOSE focus when click anywhere OUTSIDE
of that control, I call the register with the ID.

For example) QML: onFocusChanged: if (gtextfield.focus == true)
Mysingleton.gregister(gtextfield) ;

4) Install an event filter:

 QGuiApplication->installEventFilter();

Inside the event filter, I do the following:

A) Ignore messages from Qobject* obj->isWindowType() -> return false;
B) Only look for  QEvent::MouseButtonPress and QEvent::TouchBegin events
C) Use Qmetaobject*->classname() to check if the name of the obj
pointer is a pointer to ANOTHER text input field using
QString.contains() == true
D) If find your classname in the parent tree, then just return false,
do nothing, since another input control is going to appear that needs
the virtual keyboard, no sense in hiding it.
E) Make sure you check the parent tree since your class name may appear higher
F) gtextfield->setProperty("focus",QVariant(false)) -> Removes focus
on your control and hides the Virtual keyboard.

This works beautifully and is a code pattern that scales without
regard to how big your QML object->parent tree is.

And the message filter is very efficient, does not add any real
overhead to the message stack tree.

Thanks,

Md

[Interest] TextField QML auto keyboard hiding/lose focus on touch events

[mark diener]

Hello List:

Anybody have a tip or suggestion for IOS/Android Qt 5.5.1 -> Qt 5.6.0 Beta

I am using a TextField and the keyboard pops up whenever the input control
receives focus.

But I want the TextField to lose focus whenever you click/touch
outside of the control.

Not Just Tab & Enter that are VERY PC centric, not tablet/smartphone concepts.

Right now, the blinking cursor remains on the field and the
Android/IOS keyboard remains visible
when you use your finger and touch some where outside of the TextField.

Obviously, I want the keyboard to REMAIN if the user clicks on ANOTHER
TextField.

Is there a QML way to do this?

I have some C++ and event filter ideas to make this happen, but those
are brute force ideas and there might be something that I don't see in
the QML TextField documentation.

[Interest] Qt 5.5.1- 5.6beta - Android Gradle Packaging

[mark diener]

Bogdan & List:

In some of your Android Episodes (6&7), you addressed how to override
the base android activity
to include your own functionality in java code.

The next logical step is being able to change "Import Gradle Files" so
that custom packaging  are ALWAYS imported into projects.

Basically, I would like to have a new default activity that has all of
my entry points included by default and has my version of starter
files without having to watch the Android Episodes every time I want
to remember how to set up each individual project.

This of course requires some understanding of the tooling chain so
when you "Import Android Files", I can edit the script that executes
to build the file packaging.

Can you provide a little commentary about this.

(I hope this is an editable script and not hard coded into qt creator.)

Hi Thiago,

I want my app to get all notifications that are being passed through
org.freedesktop.Notifications without the app itself registering as
"org.freedesktop.Notifications" service.
I'm not sure about the best approach for that.. Do you happen to know what
might work?

[Interest] QQuickTextNode not reachable from QQuickItem

[mark diener]

Hello List:

Well after pouring thru 5.5.1 source code, I find that QQuickTextNode
is really not intended to be used in QQuickItem derived classes.

There is not visible header file from projects.

Lots of various google references to similar challenge of text in QQuickItem.

At this point, my only C++ way for custom components with text is
QQuickPaintedItem.

Anyone have thoughts on how to output text into QuickItem stuff?

Thanks,

[Interest] How do i monitor DBus functions (not signals)

[Mark Gaiser]

Hi,

I'm trying to monitor "org.freedesktop.Notifications" for the notifications
(see [1] for reference) that broadcasted from there. Every notification
ends up in a "Notify" method on that dbus interface.

I'm trying to monitor that, but kinda fail at it... I can monitor the
notifications with dbus-monitor
"interface='org.freedesktop.Notifications',member='Notify',type='method_call',eavesdrop='true'",
doing the same in code is not firing the slot i'd like it to call..

The code:

...
QDBusConnection::sessionBus().connect("",
  "",
  "org.freedesktop.Notifications",
  "Notify",
  this,
  SLOT(notify(QDBusMessage)));

// This is the exact same match line as from the command.
QString matchString =
"interface='org.freedesktop.Notifications',member='Notify',type='method_call',eavesdrop='true'";
QDBusInterface busInterface("org.freedesktop.DBus",
"/org/freedesktop/DBus",
"org.freedesktop.DBus");
busInterface.call("AddMatch", matchString);
...

In the connect line the "this" object is a simple one function class
inheriting from QObject with a "notify(QDBusMessage message)" member as
public slot.

In the app i've set the env variable: QDBUS_DEBUG=1 (for debugging purpose).

If i run my app and send a notify message like so:
notify-send -a "Chrome" "aaa"

Then i am getting console output in my app like this:
QDBusConnectionPrivate(0x623760) got message (signal):
QDBusMessage(type=MethodCall, service=":1.522",
path="/org/freedesktop/Notifications",
interface="org.freedesktop.Notifications", member="Notify",
signature="susssasa{sv}i", contents=("Chrome", 0, "", "aaa", "", {},
[Argument: a{sv} {"urgency" = [Variant(uchar): 1]}], -1) )
QDBusConnectionPrivate(0x623760) sending message (no reply):
QDBusMessage(type=Error, service="", error
name="org.freedesktop.DBus.Error.UnknownObject", error message="No such
object path '/org/freedesktop/Notifications'", signature="", contents=() )

But the slot notify(QDBusMessage) is not being called...
What am i doing wrong?

I see the error: "No such object path '/org/freedesktop/Notifications", but
if i add this to my code:
QDBusConnection::sessionBus().registerObject("/org/freedesktop/Notifications",
"org.freedesktop.Notifications", this);

I get roughly the same dbus message, but with this error:
No such interface 'org.freedesktop.Notifications' at object path
'/org/freedesktop/Notifications'

And i'm not even sure if i need to look at that error at all...

I hope someone with dbus knowledge can point me in the right direction for
this?

Thank you,
Mark

[Interest] Visual Studio 2015 32 bit debugger setting

[mark diener]

Hello List:

Anybody know how to manually setup Qt Creator debugger for Visual Studio 2015.

After installing both MSVC2015 and Qt560 beta, my debugger entries in
Build were blank.

I could not find cdb.exe or windbg.exe and nothing for downloading
Debug Tools for 2015 from Microsoft except a command line only set of
tools which will not install while full visual studio 2015 is
installed.

Also described in: https://bugreports.qt.io/browse/QTBUG-50399

But I am loooking for the manual entry of a debugger in Build & Run

[Interest] 5.5/5.6 QMLEngine management

[mark diener]

Hello List:

I have a couple of core QMLEngine questions:

Basic Code Snippet:

QQmlEngine geng ;

QQmlComponent gcomp()
gcomp.setData( ByteArrayofQML , QUrl() ) ;
gcomp.create() -> Show the QML in the QML Engine
if (gcomp.isError() == false) -> we have visible QML!

1) How does one cause all properties in the root context for QML
engine be triggered to re-evaluate their bindings again. For example
Text { text: gvariable }, it want text object to re-fetch its own
values instead of pushing values with Qobject->setProperty().  Generic
pull instead of specific push.

Can I cause a disturbance in the QmlContext and that would trigger and
"expensive" refetching of text values for example.

2) How does one clear out everything loaded in the root QmlEngine context?

What is the best way to clear the root context of qmlengine of
everything prior to calling
gcomp->setData() and  gcomp->create( ) to load brand new QML into the QmlEngine?

geng->clearComponentCache() ?  Does this really flush everything out
regardless of anything that is currently visible on-screen?

I do not want to build up a pile of QObjects in the engine, I want
them cleanly flushed out.

Thank you for any responses,

[Interest] Qt 5.5.1+ Android Activity Theme & OpenGL

[mark diener]

Bogdan:

Thanks for your answers on the previous gradle issues.

During your work on QtActivity, did you ever try to create use a custom theme?

The native Splash screen for Qt is rooted in a java function, but that
function executes way AFTER java inflation.

So attaching the custom theme to the QtActivity should in theory cause
it to appear immediately, then Android will proceed to
deflate the classes.dex and all the other stuff while the use has
something nice to look at.

I was able to create a custom theme and attach it to the android
QtActivity in Manifest.xml.



But it seems the initial color of the surface for OpenGL is black, so
there is no getting around the initial shader color
when you initialize the OpenGL surface.

What are your thoughts?

Where does one look to find the script files used by QtCreator when a
kit is added?

I would like to change the default Manifest.xml to add a theme
whenever a new project is created.  yes, I can currently edit the
manifest.xml file directly.

Also, I would like to select which is the initial color of the OpenGL
surface during initialization.  Looks like I would have to rebuild QT
to get access to that.

Cheers,

Re: [Interest] Qt 5.5.1+ Android Activity Theme & OpenGL

[mark diener]

Ben:

Thanks for the link.

I am finding that putting a white.png file for the
android.app.splash_screen_drawable in manifest works best.  That
allows for selection of the opengl initial surface.

The theme allows for pre-opengl display to the user.

This should be default behavior and adjustable in the Android Wizard,
but that is for another day.

Thanks,

Cheers,

Bogdan:

While I cannot reproduce it reliably, sometimes the Qt "Copy Files to

That file contains:

## This file is automatically generated by QtCreator.

androidBuildToolsVersion=23.0.2

Re: [Interest] Android Studio 1.5.1 with Qt 5.5.1 OSX

After getting more problems like the one below:

Failed to sync Gradle project 'android'
Error:Unable to load class
'org.codehaus.groovy.runtime.typehandling.ShortTypeHandling'.
Possible causes for this unexpected error include:Gradle's
dependency cache may be corrupt (this sometimes occurs after a network

Re-download dependencies and sync project
(requires network)The state of a Gradle build process
(daemon) may be corrupt. Stopping all Gradle daemons may solve this
problem.
Stop Gradle build processes (requires

which is not compatible with the other plugins in the project or the
version of Gradle requested by the project.In the case of
corrupt Gradle processes, you can also try closing the IDE and then
killing all Java processes.

I created another fresh project, verified it ran on Android Table.

Then added line to gradle-wrapper.properties:

distributionUrl=http\://services.gradle.org/distributions/gradle-2.2.1-all.zip

And commented out the 1.12 line.

I focused entirely on clearing out old gradle stuff from my entire
machine (OSX El Capitan, Qt 5.5.1)

Android Studio is now working with Qt 5.5.1 again.

So the lesson of the day is that as Android Studio updates from 1.4.1
-> 1.5.1, etc, you really need to go back and remove all legacy Gradle
stuff from your entire machine since Gradle gets confused.  And there
seem to be several places that leave Android Studio and Gradle garbage
on OSX.

When you first create QT projects, it may be with older gradle, then
upgrading Android studio may cause new gradle to download, but Qt and
Android studio both need entirely fresh gradle stuff or you start to
get hours of the above problems.

Hope that helps anyone.

[Interest] Dragging rectangle between multiple QQuickView instances?

[Mark Gaiser]

Hi,

I want to move a rectangle between two different "windows", but how can i
do that?

The only possible way i can think of (but i do'n't know if that would even
work) is:
- Have N QQuickView classes (lets say 2, for the sake of this argument)
- All QQuickView instances share the same QQmlEngine object
- Listen to an equivalent of dragEnterEvent/dragLeaveEvent. An equivalent
since those exist in QWidget, not in QQuickView or any of the classes it
inherits from.
- if an enter event is received on a respective QQuickView, figure out
which QML Component caused the event and change it's position to be in the
view of the QQuickView that received the event.

That's how i think it "could" work.. But it probably won't be that "easy" ;)
So before i start to fiddle with this, is there any way already to drag a
rectangle between multiple QQuickView instances? If not, is the way i
described above even possible? Or could there be a simpler way to
accomplish the same thing?

[Interest] Compile OpenSSL & NetworkAccessManager

[mark diener]

Hello List:

Referring to the following:  http://doc.qt.io/qt-5/opensslsupport.html

Quote-> "Open your Qt project using Qt Creator and update the "Build
Android APK" settings to add *libcrypto* and *libssl* as additional
libraries for your project."

Does this mean I can add both static/shared libraries and
NetworkAccessManager will use the included library instead of the Android
factory supplied openssl version?

For compatibility with Android-9, should I compile openssl with Android-9 ?

Or should I build the openssl code with Android-18 and it will work
backwards with Android-9?

(Incredible-> Qt 5.5.0 runs on Original Kindle Fire Android 2.3
Gingerbread!)

Can I simplly link the Intel x86 compiled version when using an Intel Kit
and Arm version when using an Arm kit?

How do we tell QT Creator to link IOS/OSX self compiled OpenSSL libraries
so that NetworkAccessManager will use them instead of apple supplied
openssl libraries?
(Both libssl.a/dylib and libcrypto.a/dylib)
(LIBS += /sslpath/libssl.a /sslpath/libcrypto.a?)

How does this work?

cannot imagine running MSVC2015 on the tablet just to Compile, Deploy,
Debug.

Re: [Interest] Strategies to create dialog boxes dynamically in Qml

[Mark Tucker]

Hello Nuno,

In finishUIDDialogCreation() (after your check for it being null) you can 
connect the signals you're emitting from your dialog to another function of 
your choice, for instance if you had a function named "handleOKClicked" then 
you can do this:

dialog.okClicked.connect(handleOKClicked)

Then in that function you can disconnect your function from the signal like so:

dialog.okClicked.disconnect(handleOKClicked)

(since you're destroying your dialog object, this part may not be required, but 
I like to make sure)

You can then from your function do whatever you like, including destroying your 
dialog object.

Subject: [Interest] Strategies to create dialog boxes dynamically in Qml

Hi,

I’m trying to implement a custom dialog box on qml using dynamic object 
creation methods. I’m using the javascript approach to create the component and 
then the object. The object appears on the scene and it has two buttons. The 
question is. What are the strategies available to receive the user input and 
react according? I want to be able to receive the answer and then destroy the 
dialog.

My small test:

// main.qml
import QtQuick 2.4
import QtQuick.Window 2.2

import "ObjectManagement.js" as ObjectManagement

Window {
id: window
visible: true
width: 1024
height: 768

MouseArea {
anchors.fill: parent
onClicked: ObjectManagement.createUIDialog(window)
}
}

// ObjectManagement.js

var parent
var component;
var dialog;

function createUIDialog(p)
{
parent = p
component = Qt.createComponent("UIDialog.qml");

if (component.status==Component.Ready)
finishUIDialogCreation();
else
component.statusChanged.connect(finishUIDialogCreation);
}

function finishUIDialogCreation()
{
if (component.status==Component.Ready)
{
dialog = component.createObject(parent, {"x": 100, "y": 100});

if (dialog==null)
console.log("Error creating object");
}
else if (component.status==Component.Error)
console.log("Error loading component:", component.errorString());
}

// UIDialog.qml

import QtQuick 2.0

Rectangle {
id: root
color: "yellow"
width: 300
height: 100

signal okClicked
signal cancelClicked

Row {
Rectangle {
width: 100
height: 50
color: "green"

MouseArea {
anchors.fill: parent
onClicked: root.okClicked()
}
}

Rectangle {
width: 100
height: 50
color: "red"

MouseArea {
anchors.fill: parent
onClicked: root.cancelClicked()
}
}
}
}

Thanks

Regards,

Nuno

There seems to be a better option, sometimes just staring at me in the

More news on its effectiveness.

[Interest] ImageProvider Threading

[mark diener]

Hello List:

When dealing with multi-threading, the docs say that QQuickImageProvider
will load
images in a separate low priority thread.

As it reads in the docs:

http://doc.qt.io/qt-5/qquickimageprovider.html#details

"When this is enabled, the image request to the provider is run in a low
priority thread, allowing image loading to be executed in the background,
and reducing the performance impact on the user interface."

Does anybody know if the requests are queued in a single low priority
thread or the requests are made in parallel low priority threads?

For queued, this means if we take a long time to return from requestPixMap(
) that all the other images will block waiting for each queued
requestPixmap( ) call to complete.

Who knows, parallel or serial requestPixmap( ) calls?

Thanks,

[Interest] Lovely Arabic/Persian layout challenges

[mark diener]

Hello List:

Has anybody come across how to control right to left languages with respect
to alignment application wide.

http://doc.qt.io/qt-5/qguiapplication.html#layoutDirection-prop

In my case, I need to project arabic along with english.

But the shifting of left to right layout and right to left
is not just individual component level, but application wide
and dynamic based on language toggling.
QApplication->setLayoutDirection() seems to have little effect
on QML Text

For example:

النقاط MMX:

When displayed in QML app mixes up the stored string
and re-arranges it:

:MMX النقاط

Now, that means we actually need the Text QML objects themselves to mirror
to follow along with layout.

What would be wonderful is application wide layout mirroring where if we
have a left to right language installed, the entire QML inventory could be
virtually swapped to support it and thus not require a Left to Right and
Right to Left layout for all the nicely positioned QML components that were
designed with left to right to start with.

If you have 50 QML layouts, that is a lot of work to get it looking good
with Arabic AND English unless you dedicate a separate set of QML inventory
to support Right to Left.

Any body have some reflections and/or tips on this?

Especially anybody from Arabic part of the community.

Re: [Interest] Windows deployment. Failed to start because of missing platform plugin...

[mark diener]

I just tried to use windeployqt on my freshly built qt 5.5.0 compiled with
MSVC2015 and the latest Qt Creator 3.50 on Windows 10

The tool defaults to deploying the debug version, even though I pointed it
to the release executable.

It succeeds building the debug version of things. It fails to build release
version.

One failure is the inability to find the platform plugin.

Just like you guys were talking about.

Anybody got a clue why windeployqt fails on release builds?

Re: [Interest] Qt 5.5.1 MSVC 2015

[mark diener]

I can say that shadow building method definitely has a problem.

When I built with same configure/nmake from the source directory, it built
all the way until I got an unresolved externals.

But my earlier information was solved by NOT Shadow building on Windows 10
with MSVC2015.

Only build from the source root directory itself.

More news soon.

 Ok, the first error is the most important.

 I made sure I added your -I and -L suggestion
 and tried to capture errors to a log file.

 There is a required space between -I C:\, it does not seem to allow
 -IC:\

 Seems like the build process is ignoring the:  -IC:\macdev\openssl\include
 directive

 Attached are files:
 A) builderrors.txt is the output generated by nmake /x
 B) buildoutput.txt is the last bit of console output
 C) configure.txt is the console output of the configure command
 D) rpzbuild.bat.txt is the shadow build batch file (txt added to pass
 google email filter, its a batch file)

 Seems like every thing is in place from the configure output.

 I downloaded the source from:


 http://download.qt.io/official_releases/qt/5.5/5.5.0/single/qt-everywhere-opensource-src-5.5.0.zip

 510 mb zip file.

 Running on Windows 10 with MSVC 2015 community edition.

 What do you think?
 Download source from different place?
 Where are you getting yours from, GIT clone?
 Should I actually get openssl sources and build them too?

 Cheers,

 Yes. I have been doing just that since last November.

  There are people on the list that will want to build qt5.5.0 and
 qt5.5.1 if

  So I would like to document a HOWTO for people in the community to
 repeat
  step-by-step to build Qt5.5.0 from sources.

 configure -platform win32-msvc2015 [your other configure options]
 nmake

  I did try to compile from qt.5.5.0 sources and ran into openssl path
  errors.  Once I solve the openssl problems, I will likely run into
 others.

 Unrelated to MSVC 2015.

  Building from sources
  is trivial when everything goes right.
 
  Since openssl is needed and it does not come standard on a Windows
 machine,
  and since there is no yum install openssl on Windows 10, I found
  a MSVC2015 compiled developer ready package for the latest library and
  header files from the following link:
 
 
 http://p-nand-q.com/programming/windows/openssl-1.0.2d-32bit-release-dll-vs2
  015.7z
 
  Unzipped an put into: C:\macdev\openssl  directory

 Then add to configure:
 -IC:\macdev\poenssl\include -LC:\macdev\openssl\lib -openssl

 [I see you have in your script]

  MANY SSL ERRORS ABOVE - But the net result:
  c:\macdev\qt550\src\qtbase\src\network\ssl\qsslsocket_p.h(185): error
  C2061: syntax error: identifier 'QSslCertificate'

 The most important error is the first.

For those who want more security, build your openssl from sources.  But
that is not the goal here, we want to compile qt5.5.0 from sources using
MSVC2015 Community edition.

Using the git configure as a guide, I tried to do emulate as close as
possible the binary package build:

http://code.qt.io/cgit/qtsdk/qtsdk.git/tree/packaging-tools/releases/release-55?h=v5.5.0-packaging

The closest config I could find was:

-opensource -confirm-license -debug-and-release -release -nomake tests
-nomake examples -qt-zlib -qt-libjpeg -qt-libpng -opengl dynamic
-plugin-sql-mysql -plugin-sql-psql -plugin-sql-sqlite -plugin-sql-odbc
-openssl -target xp -dbus

So I removed the -target xp and removed some database stuff since I don't
need it)
Added in a platform option to point to the correct mkspec.

Here is my shadow build batch file:

What?

My -no-openssl and -no-ssl should beg the question why Qt build process
wants openssl.

[Interest] Qt 5.5.0 Compile Time Hash Example

[mark diener]

Hello List:

Have you ever wanted an efficient switch statement on QString values?

There are many references to the subject with various algorithms, but they
all have some major flaw in the implementation.

For those looking for a way to have compile and run time hash on their
strings, I spent a little while doing some research on the subject and
wanted to share back to Qt community:

The tests ran successfully with the C++11 example for OSX/IOS Xcode 6.3.2
and Android NDK 10 r10e,

I went ahead and tested the function on MSVC 2013 with CTP November and it
failed.  MSVC 2015 worked, but I could not build the QT 5.5.0 source code
successfully, so I just built a console app in MSVC2015 and the C++11
function worked.

The C++14 example did not work on OSX or Android, but it did work on IOS.
With 2 out of 3 failures, I did not feel motivated to test for MSVC 2015 on
Windows 10.

So for those wanting to verify and make use of it, here are the required
code snippets:

First, in your .PRO file:

#CONFIG += c++14

CONFIG += c++11


Now for a source sample:


//main.cpp ##//VALID C++14 Constant Expression
Function (Compiles for IOS on Qt5.5.0 and XCode 6.3.2, but does not
Compile for OSX Desktop with Clang)/*constexpr unsigned int
fnhash(const char *gpstr){unsigned int hash = 0;size_t gidx =
0 ;while (gpstr[gidx]  0){hash = 65599 * hash +
gpstr[gidx];if (gidx  15) break ;gidx++ ;}
return hash ^ (hash  16);}*/// ##//C++11
Constant Expression Function
//Forward declarationconstexpr unsigned int fnhashrec(unsigned int
hash, const char* str) ;
constexpr unsigned int fnhash(const char* str){   return ( !str ? 0 :
fnhashrec(5381, str) );}
constexpr unsigned int fnhashrec(unsigned int hash, const char* str){
 return ( !*str ? hash : fnhashrec(((hash  5) + hash) + *str, str +
1));}// ##
int main(int argc, char *argv[]){QGuiApplication gapp(argc, argv);
   QQmlApplicationEngine geng;
QString gval = JOKER ;

//NOW look at the run time eval from QString - char*

switch (fnhash(gval.toUtf8().data())){case fnhash(PETE):
 //Compile time optimizedqDebug()  POOR PETE IS NOT A
JOKER  endl ;break ;case fnhash(JOKER): //Compile
time optimizedqDebug()  BLOODY JOKER WORKED - SUCCESS 
endl ;break ;}
geng.load(QUrl(QStringLiteral(qrc:/main.qml)));return gapp.exec();}

[Interest] Accessing QML Loader from C++

[mark diener]

Hello List:

Does anybody have an idea on how to retrieve the QObject* from C++
with a QML Loader::item property?


Is it possible to pass a item to Q_INVOCABLE and get a valid QObject*
inside the called
invoked function (from QML-C++)

Is there a risk of blowing memory if I setContextProperty( ) on the
QQmlContext of the Loader QML element?

There does not seem to be a QQmlContext::removeContextProperty( ) function
call,
but the API does accept setContextProperty(myobj,NULL).

What is the way to manage memory usage used by setContextProperty( ) call.

Thanks,

[Interest] Qt 5.5.0 Import Paths Missing

[mark diener]

Ran into a project where the Qt 5.5.0 package builder is confused
and the application cannot find the modules.

This is being run inside Qt Creator 3.5.0 and the
QQmlApplication::importPathList()
does not provide the testgui.app/qt_qml path, it is missing a path, so the
Qml engine
cannot find it.

This problem is discussed earlier here:

https://bugreports.qt.io/browse/QTBUG-355602

This is not a macdeployqt question, I am still running the app inside Qt
Creator in development.
So it is NOT user error as was referenced in the bug report which finally
closed the bug report.

So how does one COMPLETELY reset and clean a project on IOS so that the
package builder
feels compelled to rebuild everything to include the testgui.app/qt_qml
path in the import path list?

Have a great day,

md

Here is Qt Creator application output:

Re: [Interest] Qt 5.5.0 OSX Simulator fail

[mark diener]

Hello List  IOS Maintainer Tor Arne:  (tor.arne.ves...@theqtcompany.com)

I would like to suggest some hard lessons learned today.

I upgraded to 5.5.0 and was primarily getting my code running on OSX to
make sure it basically worked.  I could then deploy to IOS Simulator/IOS
and android to validate the code worked there.

I tried using Qt 5.5.0 on Yosemite 10.10.2 and Xcode 6.1.1 / 6.2 but that
turned out to be a disaster.

When I moved back to Qt 5.4.2, I gained IMMEDIATE relief.  All of the
strange xcodebuild errors went away.

The basic project I tried for HOURS to get running on IOS and IOS simulator
under Qt 5.5.0/Xcode 6.1.1 immediately WORKED on Qt 5.4.2 on Xcode 6.1.1

So I went to start looking at the CI system with an eye for knowing what
combinations of OSX, Qt 5.x.x, and Xcode 6.x are safe combinations
and which are explosive.

https://wiki.qt.io/CI_Configurations
http://testresults.qt.io/qtmetrics/metricspageci.php

What I found was that the CI system is only running OSX Mavericks and I was
not able to determine what sort of simulator or IOS device tests were being
run.

Maybe the IOS maintainer and the Continuous Integrator CI maintainer might
allow me to make sense of which combinations of Xcode/OSX/Qt/IOS are best
kept together.

I know the upcoming patch of Qt 5.5.1 for Windows 10 support is a good
pairing, but what is a good XCode to pair with Qt 5.5.1?

Cheers,

md
