Re: [Interest] iOS build request permissions I don't need

[Gian Maxera]

The permission are not listed into Info.plist … are derived/assumed by 
iTunesConnect when see what framework have been used.

In any case, Nuno Santos suggestion is working.

Thanks again for your support.

[Interest] iOS build request permissions I don't need

[Gian Maxera]

Hello,
I’ve recently updated an app using Qt 5.7.0 and when I submitted this update to 
iTunesConnect the build has been rejected for this reasons:

I don’t use CAMERA and I don’t use PhotoLibrary into the app. So, I don’t know 
why Qt inject these permission.

I’m using a WebView for mobile.

How can I remove these ?

Thanks,

Re: [Interest] Android build add permission I don't need

[Gian Maxera]

Ok, I’ll try to do it.
But I always trusted on Qt permission inclusion, so actually … I don’t know 
what permissions my app need.
Because it’s really a basic app, I don’t think it needs more that default 
permissions.

[Interest] Android build add permission I don't need

[Gian Maxera]

Hello,
I’ve recently updated an app using Qt 5.7.0 and when I submitted this update to 
Google Play I had this warning:

"Your app has an APK with version code 28 that requests the following 
permission(s): android.permission.CAMERA,android.permission.RECORD_AUDIO. Apps 
using these permissions in an APK are required to have a privacy policy set.”

I don’t use CAMERA and I don’t use RECORD_AUDIO into the app. So, I don’t know 
why Qt inject these permission.
I’m using a WebView for mobile.

How can I remove these ?

Thanks,
Gianluca.

I think that is not mandatory under LGPL license. Of course, it would be a nice 
to do because all the community can benefit from your work.
But from a formal point of view, I don’t think you are enforced to do so.
The only thing your are enforced to do is to release the fix under LGPL license 
too. That means you cannot sell under commercial terms your fixed-Qt version, 
instead you have to give for free to anyone would ask to you.

Re: [Interest] Towards a better mobile launch?

[Gian Maxera]

What is your target launch time ?

Because in my apps I use a splash.qml file that contains an Image, an Animator 
and a Loader. Anything else.
And then the Loader will load the real main.qml of the application.
In that way, the launch time is around 2 seconds… then with a bit of creativity 
into the Animator you can craft an animation that fakes load all other elements 
of your user interface.

Ciao,
Gianluca.

Never got this problem.
This is my steps:

 1. Set Qt Creator to iphoneos release (I never used debug version for creating

 2. Only “Run Qmake” from Qt Creator
 3. Open the Xcode project present into the build directory with Xcode
 4. Archive and submit

Never got any error in this way.

I use the following approach:

This is the ListView with the Loader inside:

ListView {
id: subsectionsList
model: navList.model
delegate: Loader {
id: innerItem
width: subsectionsList.width
height: subsectionsList.height
asynchronous: false
property var models: sectionModel
source: sectionPage
}
}

Then, I create the model in the following way:

ListModel {
id: subsections
// it's not possible to use the 'static' initialization:
//ListElement { ... }
// because it does not support passing of object pointers
Component.onCompleted: {
append( {
'sectionName': "Hotel details",
'sectionPage':"HotelDetailsSubsection.qml",
'sectionModel': {
'event': event,
'hotel': hotel
}
})
append( {
'sectionName': "Exhibitors",
'sectionPage':"HotelExhibitorsSubsection.qml",
'sectionModel': {
'event': event,
'hotel': hotel
}
})
}
}

Pay attention on two key passages:
 - the Loader inside the ListView has a property for keeping the models: 
“property var models: sectionModel
 - the ListModel contain an attribute ‘sectionModel’ that it’s an object with 
the Items I want to inject and pass to my loaded items inside the ListView

And then, into the source code of QML component I can use the model like that:

Text {
text: models.hotel.description
}
Text {
text: models.hotel.city_and_country+' 
'+models.hotel.address+' '+models.hotel.postcode
}


Do you like it ?

The app stores doesn’t allow to easily share a testing app with the client. 
Both stores they requires subscriptions as a kind of tester or developer. 
Neither works when you need to show the works done with a client that just need 
to see what you have done and sign off and pay the invoice.
In this case, I cannot use the testing features used by app stores … because, 
as I said, I have to give the possiblity to install both version on the same 
device but working on different environments.

I don’t want to re-invent the wheel … that’s why I’m asking if there is a 
solution out there that fits my needs… but it’s seem there isn’t :-(

[Interest] Android and iOS: how to easily handle 'staging' and 'production' versions ?

[Gian Maxera]

Hello all,
I often need to keep two version of the app: ‘production’ that it’s the current 
app live on the stores and ‘staging’ that it’s an app deployed only to the 
client and testers for the new upcoming release.

Of course, I don’t want to use the same package name for the apps, so let’s 
suppose I’d like to have: ‘com.mycompany.staging.coolapp’ for staging and 
‘com.mycompany.coolapp’ for the one on stores.

For now, switching from one build to another build, it require my to manually 
change the java source directory tree, the java package name at the top of each 
java class declaration, the package name into AndroidManifest and Info.plist.

Do you find an automatic way to handle this switch of build environments easily 
?

Thanks,
Gianluca.

Re: [Interest] including config file with macdeployqt

Mac bundle (after all) is just a directory.
So, you can just copy the config file where you want inside the directory and 
access it getting the path relative to application dir path

Re: [Interest] AndroidManifest Minimum required API not working as expected

[Gian Maxera]

I suppose that qmake is generating different Makefiles depending on what is 
using for build the java part.

So, my supposition is:
 - when you select “ant” as java builder, then Qt Creator generate a Makefile 
for using “ant” … and this may contain some bugs that doesn’t allow to change 
the Qt app name and the Android SDKs
 - when you select “gradle” as java builder, then Qt Creator generate a 
(different) Makefile for using “gradle” … and this may be bug-free (because I 
didn’t have any problem on setting Android SDKs) … and using “gradle” allow to 
change other aspect of java building overriding gradle.properties.

Re: [Interest] AndroidManifest Minimum required API not working as expected

[Gian Maxera]

I don’t think the problem is on makefile … but on the tool are using.
I want to insist on check if you are using gradle … because I don’t have any of 
your problem with default settings of Qt Creator and using gradle.

When I create a new project with Qt Creator and I set to use gradle … the app 
name is correct and I can change the sdks.

Re: [Interest] How to set Android Version and App Name

[Gian Maxera]

It seems are you using “ant” for building the app.
You should switch to “gradle”.
“ant” has been deprecated years ago, and I never got your problem using “gradle”

Ciao,

I think so, but instead of bind x and y … I’ll try to change the parent. There 
is also ParentAnimation for animate the changing.
And then, you can use the anchors for center the Figure in the parent.

Figure {
anchors.centerIn: parent
}

But I don’t know if QML got some built-in to find an object by name.

With my solution you cannot use anchor.horizontalCenter because you are inside 
a Row.
What you need to do is to set the width of the Text element and use 
horizontalAlignment.
I suppose that in same way you are calculating the dimension of the cell during 
resize, so the code will be like for the Text:

Text {
width: cellWidth
horizontalAlignment: Text.AlignLeft
}

One solution using Column and Row instead of Grid to split Repeaters:

Column {
spacing: 0
Row {
// top letters
EmptyItem { // use fixed width here so you can align the text }
Repeater {
model: [“A”, “B”, … “H”]
delegate: DisplayTheLetter { … }
}
EmpyItem { }
}
// Rows with cells
Repeater {
   model: 8
   delegate: Row {
   // number
   Text {
// use fixed width and align left the text
// vertical alignment with anchors
anchors.verticalCenter: parent.verticalCenter
text: index+1
   }
   // first row of chess board
   Repeater {
model: chessBoardModel[index]
delegate: ASingleCellOfChessBoard { … }
   }
   }
}
Row {
// bottom letters
EmptyItem { }
Repeater {
model: [“A”, “B”, … “H”]
delegate: DisplayTheLetter { … }
}
EmpyItem { }
}
}

I don’t know your current code, but If I would in your shoes, I will use a 
model representing where to put the chess items and a Grid to lay out the 
items. With Grid Item you can setup a global alignment of the items.
I think it should work in your case.
If you want more help, please share with us some snippet of code so I can 
understand what you need to achieve.

Re: [Interest] QML id

[Gian Maxera]

If the Text is inside the generated rectangle into the repeater you don’t need 
to generate different Ids, you can do that:

Repeater {
  model: 10
  delegate: Rectangle {
 id: cellRect
 Text {
anchor.horizontalCenter: cellRect.horizontalCenter
 }
  }
}

Even if the delegate has a fixed id and generated 10 times, QML will resolve 
correctly it.

Ciao,
Gianluca.

[Interest] Strange ordering problem with ComboBox

[Gian Maxera]

Hello,
I’m using the ComboBox item of QML with more than two Items with a ListModel 
like that:

ComboBox {
id: rateType
anchors.horizontalCenter: parent.horizontalCenter
width: parent.width*0.9
Component.onCompleted: {
if ( models.appointment.lead == null ) {
rateType.currentIndex = 0
} else if ( models.appointment.lead.type == 'contact' ) 
{
rateType.currentIndex = 0
} else if ( models.appointment.lead.type == 'brochure' 
) {
rateType.currentIndex = 1
} else if ( models.appointment.lead.type == 'tentative' 
) {
rateType.currentIndex = 2
} else if ( models.appointment.lead.type == 'definite' 
) {
rateType.currentIndex = 3
}
}
model:  ListModel {
ListElement {
leadType: 'contact'
leadText: 'Contact only'
}
ListElement {
leadType: 'brochure'
leadText: 'Brochure request'
}
ListElement {
leadType: 'tentative'
leadText: 'Tentative lead'
}
ListElement {
leadType: 'definite'
leadText: 'Definite lead'
}
}
textRole: "leadText"

But the popup menu appearing for select the option contain the elements into a 
different order than ListModel and when you select one of those the ComboBox 
select a different one. In such a way that it seems the index are correct but 
the labels of the popup menu are wrong.

Someone hits this error before ?

I’m using Qt 5.5 for now.

Ciao,
Gianluca.

One reason that for me it’s fundamental: Readability of your code !!!

Even if it wouldn’t necessary to declare “public slots”, I really strong advice 
to use “slots” because it explicitly say what part of your interface are 
supposed to be attached to a signal and what part not.

It’s very common on my C++ code that only a subset of method are mean to be 
attached to a signal, so make this distinction clear help to understand the 
code and debug it more easily.

Then, I don’t know if there is a real difference on connecting to a function or 
to a explicitly declared slot. But for sure, you cannot use always lambdas. So 
methods acting as slot are necessary.

Gianluca.

[Interest] Can I access dynamic properties defined in C++ into QML ?

[Gian Maxera]

Hello,
If I set a dynamic properties from C++:
void CloudModel::setPropertiesFromJson( QJsonObject json ) {
foreach( QString key, json.keys() ) {
QJsonValue value = json[key];
setProperty( key.toLatin1(), value.toVariant() );

then, I cannot access any of these new properties from QML side even if 
CloudModel has been exposed to QML with qmlDeclareType.

Is this an intended behaviour or Am I doing something wrong ?

Thanks,

Re: [Interest] Dynamic translations for mobile apps at runtime?

[Gian Maxera]

Hello Jason,
I got the same issue some times ago … and I found that it’s possible to use the 
translation feature of Qt … that seems static, but it’s not.
And localize.biz it’s a wonderful site that allow you to modify Qt translation 
files directly on web and download the updated one.

The trick to achieve (summarized) is the following:
Somewhere in your code maintain and update from remote an array of Translators:
translators["en"] = new QTranslator(this);
translators["en"]->load( "tr_en", commonPath()+"/translations" );
translators["de"] = new QTranslator(this);
translators["de"]->load( "tr_de", commonPath()+"/translations" );
translators["fr"] = new QTranslator(this);
translators["fr"]->load( "tr_fr", commonPath()+"/translations" );
translators["ru"] = new QTranslator(this);
translators["ru"]->load( "tr_ru", commonPath()+"/translations" );
You can change these entry with new files downloaded at runtime.

Then you implement a method that you call at runtime for changing the 
translator, something like that:

void Backend::selectLanguage( QString language ) {
foreach( QString lang, translators.keys() ) {
if ( lang == language ) {
qApp->installTranslator( translators[lang] );
} else {
qApp->removeTranslator( translators[lang] );
}
}
this->language = language;
emit languageChanged();
}

And then there is the final trick:
You create a “fake” property that is always an empty string but it’s binded to 
languageChanged signal:

Q_PROPERTY( QString es READ getES NOTIFY languageChanged )

And (the most annoying part), append this empty string to all string you want 
to change at runtime like that:

qsTr("NEWSHUB")+backend.es

And close the loop.

What will happen is the following: the translator change at runtime and you 
trigger a languageChanged that trigger an update of all string that got 
backend.es appended that trigger the call of qsTr that take the new translation 
from the new translator.

Ciao,
Gianluca.

[Interest] iOS Violation constraint using WebView

[Gian Maxera]

Hello,
I’m using the same approach of the example for viewing Youtube video using 
mobile WebView, but I’m getting a strange error on iOS 9
I can press play and the video start to play. The video go to fullscreen and I 
can rotate the device to landscape but when I do I got the following error:

Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one 
you don't want. 
Try this: 
(1) look at each constraint and try to figure out which you 
don't expect; 
(2) find the code that added the unwanted constraint or 
constraints and fix it. 

Now, because I’m using QML for my app the debug information and the suggestion 
does not provide me any clue at all on how to solve the problem.
Please, someone can help me on this ?

Re: [Interest] Animating a gradient

[Gian Maxera]

Ok, that’s explain also because onPositionChanged does not work.
The property has no signal notify changes. So, it means you cannot do what you 
want.

So, my workaround is:
 - define a property and animate this property
 - refer this property into gradient

Rectangle {
  id: myRect
  property real gradPosition: 0.98
  gradient: Gradient {
  GradientStop{ … ; position: myRect.gradPosition }
 …

Re: [Interest] Destructor appearing twice in the stack trace?

[Gian Maxera]

Are you sure that in some way it’s not child of itself ?
Qt automatically destroy all children of an QObject … and I really don’t know 
how safe is Qt to assign itself as child.

You are calling delete on the same object into the destructor. You are doing 
something like that:

delete this

inside the destructor.

Maybe there is some internal variable that got the “this” value and force the 
object to try to destroy itself.

[Interest] A bug on QtAndroidMediaPlayer ?

[Gian Maxera]

Hello,
I’m trying to use QML Video item on Android and I got this error:

" No implementation found for void 
org.qtproject.qt5.android.multimedia.QtAndroidMediaPlayer.onStateChangedNative”

It seems that JNI cannot find the implementation of that method.

Is it a bug ?? Someone found already ?

Re: [Interest] Commercial license for embedded project

[Gian Maxera]

Daniel, I agree with you.
An even worst, now all the website offering a library competing with Qt as a 
clear pricing table with all information.
I really don’t understand why Qt decided so.
I remember the old website of Qt… on the menu there was a “Pricing” entry and a 
clear page with all prices. Was so clear. Why they removed that I don’t know… 
and no one on this mailing list got an answer. We asked various time and no 
answer at all about this strange decision that seems to not improve the Qt 
clients.

I always remain with Qt because I know Qt for a long time and I know how good 
is its products … but I found difficult to show to my colleques because the new 
website it’s so confused, lacks of pricing table, lacks of examples :-(

Ciao,
Gianluca.

Re: [Interest] How to deploy an app to use Qt Quick 2D Renderer?

[Gian Maxera]

For me it simple means that you have to define the environment variable into 
your operating system.

On Mac and Linux you can change the environment variable just using export from 
the terminal.

So, try this if your are on Mac or Linux like OS from terminal:

export QMLSCENE_DEVICE=softwarecontext
./yourAppExecutable

On windows like OS, you have to go into system settings and set up an 
enviroment variable.

Ciao,
Gianluca.

I need to do 2 things:

2) run a custom command after the dSYM has been created.

Re: [Interest] Qt iOS without QML?

[Gian Maxera via Interest]

Yes, it’s possible. Never done personally, but I saw some old post of 
developers successfully created iOS app using only Qt Widgets.
They said that it’s incredible faster respect to QML, but I think you lack all 
the flexibility of QML.

Re: [Interest] Qt iOS without QML?

[Gian Maxera via Interest]

I don’t have any example I can show to you, but I use QML as the ui and C++ as 
the logic part in all my Android and iOS application and it’s very 
straightforward.
There are two steps involved:
1) all C++ classes you want to expose to the UI have to inherit from QObject 
and use Q_PROPERTY for all attributes you want to access from QML and use Slots 
and signals are you normally do in Qt
2) register to QML the classes you want to see into the UI.

The step 2 can be done in different ways. What I normally do is to create a 
singleton C++ class, and I register it into the following way:

qmlengine->rootContext()->setContextProperty( "backend", this );

And then from the QML, I get all other objects passing via properities of the 
Backend singleton:

C++:
Q_PROPERTY( QQmlListProperty aboutLinks READ getAboutLinks NOTIFY 
linksChanged )

QML:
Repeater {
model: backend.aboutLinks
delegate: GoldButton {
property Link link: modelData
anchors.horizontalCenter: 
parent.horizontalCenter
width: aboutTheShow.width*0.8
height: container.buttonHeight
text: link.text
onClicked: 
Qt.openUrlExternally( link.url )
}
}


And thanks to signals and QML property binding … everytime you change the 
aboutLinks property on you C++ logic (for example listening on HTTP for 
notifications), automatically the QML will be updated to reflect the new 
changes.

Of course, there is other ways to do it. This is my way :-)

Ciao,
Gianluca.

Re: [Interest] Best way to handle database migrations on QML

[Gian Maxera]

Hello Daniel,
I also develop website using Laravel (a PHP framework), and for migration they 
use a special table called “migration” with two column: “migration” and “batch”.
The “migration” is a unique name identifying the migration.
“batch” is a incremental number indicating where the migration has been done.
Suppose in the table you see:

“Migration 1”, 1
“Migration 2”, 1
“Migration 3”, 2
“Migration 4”, 3
“Migration 5”, 3

This it means that your database has been “migrated” three times. The first 
time it apply “Migration 1” and “Migration 2”, the second time it apply 
“Migration 3” and the third time it apply “Migration 4” and “Migration 5”.

I don’t know if it’s a suitable approach for your case. But it seems to me 
simple and effective.

Ciao,
Gianluca.

[Interest] How to create a library with Android java source

[Gian Maxera]

Hello,
I’m moving all my common source files into a library and share the code between 
my Qt projects.
The qmake .pri file works fine … but I have problem on how to include also Java 
source files when the target is Android.

I found this blog:
http://imaginativethinking.ca/what-the-heck-how-do-i-share-java-code-between-qt-android-projects/
 


Is there no other alternative ??

To qmake developers: can we make this process easier ?

[Interest] MouseArea not working when using QQMLApplicationEngine with Window

[Gian Maxera]

Hello,
I’m getting a strange behaviour and I didn’t find what’s wrong in my code.
I developed various app for Android and iOS using Qt and I always used the 
QQuickView and a simple Item as the QML root item.
In this case everything works perfectly.
This is a minimal setup that works for me fine on Android and iOS:

main.cpp:

QQuickView viewer;
backend->setQuickView(  );
viewer.setResizeMode( QQuickView::SizeRootObjectToView );
viewer.setSource( backend->commonPath()+"/qml/main.qml" );
viewer.show();

and into the main.qml:

Item {
anchors.fill: parent

Rectangle {
anchors.fill: parent
color: "steelblue"

Text {
anchors.centerIn: parent
text: "Hello World !!"
}

MouseArea {
anchors.fill: parent
onClicked: {
console.log(“CLICKED”)
}
}
}

Component.onCompleted: {
console.log(“COMPONENT LOADED")
}
}

Now, I would like to give a try to the QQmlApplicationEngine used with a Window 
as root item. It allow me to have potentially more interesting features to use 
into the apps.

But when I change the code in the following way:

main.cpp:

QQmlApplicationEngine engine;
backend->setQmlEngine(  );
engine.load(QUrl(backend->commonPath()+"/qml/main.qml"));


and the main.qml:

Window {
visible: true

Rectangle {
anchors.fill: parent
color: "steelblue"

Text {
anchors.centerIn: parent
text: "Hello World !!"
}

MouseArea {
anchors.fill: parent
onClicked: {
console.log(“CLICKED”)
}
}
Component.onCompleted: {
console.log(“COMPONENT LOADED")
}
}

}

I don’t get any print on the console. No print for component loaded, and no 
print when I touch inside the MouseArea !!
Why ?? What’s happening ?

Ciao,
Gianluca.

[Interest] Qt.io confusing website ... where are the pricing table and how to get indie license ?

[Gian Maxera]

Hello,
I don’t know if in this mailing list there is someone in charge of developing 
the Qt.io new website … so, sorry If I’m complaining on the wrong list, but the 
new Qt.io website is a nightmare maze ! :-(
There is no way to understand what Qt does on different platform and license.
Where is a simple pricing table with what’s included or not ? Where is a list 
and a comparison of what it’s included for each commercial license ?
What are the purpose of the wizard-questions that get you to one of the Qt 
products ? The questions are very strange and weird ! 
Why I cannot just select the type of the license I want without answering to 
all these questions ?
How can I get the indie license ? I tried to answer in different ways trying a 
lot of combination … but I always end on two possible outcomes: LGPL free and 
350$/month commercial one !
So, are there only two type of licensing ? So, why just do not clear say that 
on the website ?

Sorry about this complain … but I’m complaining because I love Qt … and the old 
website was so good, so clear, so simple … that this new confusion, obscure 
website does not help me to spread the voice about the powerful of Qt.

Ciao,
Gianluca.

Re: [Interest] Qt.io confusing website ... where are the pricing table and how to get indie license ?

[Gian Maxera]

Let’s focus on the website and Qt … because even If I want to convince a big 
company to move and using Qt … how can I do that if the Qt website is so messy 
and so a disaster ?
I don’t think a company that can afford 350 $/month will be convinced by the Qt 
website that their product is reliable and trustable … because (maybe it’s my 
bias) but everything some commercial doesn’t give me a clear view of their 
product and a clear view of pricing … I always think that his going to cheat me 
in someways. Maybe it’s me … who knows :-)
We don’t know how many commercial licenses Qt sell and how much is the Qt 
profit.
Why don’t share also this information on the website ?
I think is can be very useful for catching new customer to clear state on the 
website something like that: “We have 14500 companies that rely on Qt 
Commercial license”

Ciao,
Gianluca.

Re: [Interest] static build for android and ios

[Gian Maxera]

The advantage on mobile is the size of the App.
Qt is made of module, if you compile it statically, you don’t have a giant big 
library, but a lot of static modules.
So, every module link against (at least) QtCore … that means you have a lot of 
duplication of static code to link against it
and the result will be a bigger app full of duplication of object code.

Another advantage is the startup time. A static app is a big .exe to put fully 
on the memory before to start the app. That means if your app is bigger of 40Mb 
at startup your mobile device need to fully load it into memory before start 
the app.
If it’s dynamic link, the library are loaded only when needed. That means, if 
your app is only 2Mb of code, you load at startup only 2Mb and then when some 
features are needed the corresponding library is loaded.

Re: [Interest] Performance of Qt scripting on iOS

Yes … that’s the reason. Of course having only a dual core does not help.
To avoid bad user experience, I wrap the delegates into Loader items, or the

message that disappear when the Loader complete to load everything.

If you can use dynamic link … use dynamic link !! There is only advantages over

on iOS, is the Apple policy that forbid that ! :-( Why ??? Maybe because using 
dynamic linking you can embed executables and run them inside the app.
Ehehe… it was a trick I used into an Android app for using ffmpeg from the app.

 It's a starting point for discussion of a whole new pricing model.
 
 The important thing is that everyone should be able to afford to develop with 
 Qt. The Qt Company should benefit if a Qt app makes a million sales and this 
 would be balanced by all those apps which are complete duds.
 
 I know there's more complexity than what I have proposed but as a starting 
 point to a new model where everyone can afford to use Qt will end with a 
 model where developers flock to Qt by the thousands and The Qt Company will 
 remain viable if not extremely successful.

Re: [Interest] Indie Mobil Program terminated?

[Gian Maxera]

I completely agree with Nuno Santos … and I’m very happy that I got an indie 
license when it got a chance.
I’m regretting my choice to not take one few months ago :-( :-(
I’m very sad because we are a small team, just three people that during the 
night we are working on a video game for mobile platform. I convinced them to 
use Qt to have just one code to maintain, of course we don’t have money to pay 
such a big pricing now.
That means we are dead before to start ! :-( and we wasted months of developing.

I want to be honest. Because we invested so much time on developing with Qt, we 
are truly considering to submit the app on the store with LGPL licence even if 
it’s risky and probably illegal … hope to make enough money to buy a Qt (very 
expensive) license in the future.
This is what Qt wants ? 

I agree with Nuno Santos that the Qt licensing schema is absolutely confusing. 
You don’t have a very nice and clear pricing table … but also there is nowhere 
a clear statement of what you get more when you pay. Honestly, do you think 
that having professional support only justify more than 300$/month ?? Because, 
I don’t see any other thing respect to LGPL version of Qt.

Please, give the possibility to indie developer to submit mobile app to the 
stores. We only needs this and nothing else.

Thanks,
Gianluca.

 It’s not easy to convince people that they should adopt Qt for iOS and

 If you had this price tag one year ago. All the work I have been developing

 If I wasn’t already a indie developer subscriber, right now, I would be in a

 I also AGREE with many of the statements already shared in this discussion

 There SHOULD be an item on the website clearly saying: PRICING

 their apps
 with a hope that future expected Qt stability and features can deliver
 stable Qt-based applications for iOS and Android.
 
 Let's say you have this product for 1 month, optimistically for 2-3 months
 (many developers to say that even today iOS/Android ports stability
 is not enough to start using it).
 
 Is it enough time to make a judgement?
 
 Qt for Desktop is the best GUI framework for today,
 and I'm confident that in 2-3 years Qt for Mobile will be as lucrative
 as for Desktop.
 
 However, this is not the case today and your product for Mobile is too risky,
 too limited with only enthusiast and early adapters starting to try it.
 
 Even if you restore the Indie license tomorrow, it will take
 some time to convince developers that Qt for iOS/Android is stable enough,
 it will take more time for developers to accomplish their applications
 full of work-arounds
 around Qt-issues and missed features and to start orders.
 
 Please, let your decision makers to look into this very interesting 
 discussion.
 
 Consider making your Indie for Mobile less restrictive i.e.
 with higher threshold like 300 000 or 500 000.
 
 Thanks.

 Robert

Re: [Interest] Qt 5.5 vs 5.4.2 for iOS and Android: Is It Worth to Upgrade?

[Gian Maxera]

I upgraded now to Qt 5.5.
I have a Stackview with a custom transition … and it doesn’t work anymore :-(
I think something changed from Qt 5.4.2 to 5.5 about scaling and/or 
transformation that is not backward compatible :-(

 Gentlemen,
 Which new features and fixes are making it worth
 upgrading to 5.5 from 5.4.2 at iOS or Android?
 
 I'm counting for iOS:
 1. pickup dialogs and images and multimedia files;
 
 Is it anything else you why you believe Qt-5.5 is worth
 considering for iOS and Android?
 
 Thank you.

Re: [Interest] ListView currentItem not changing (5.4)

[Gian Maxera]

The currentIndex does not follow the swipe and scrolling of the list by default
For doing this, you have to set up:

highlightRangeMode: ListView.StrictlyEnforceRange

 Subject: [Interest] ListView currentItem not changing (5.4)
 
 I'm trying to use a ListView with a VisualItemModel
 
 The ListView is horizontal and displays three first time help screens. The
 user can swipe left/right between them. Only one is ever on the screen at
 once.
 The user is also provided forward/back buttons.
 
 highlightFollowCurrentItem: true
 snapMode: ListView.SnapToItem
 
 The buttons work. And the swiping works visually, but the buttons and
 swiping cannot be used in combination because the
 onCurrentItemChanged/onCurrentIndexChanged never fires.
 
 How can I know what screen the user has swiped to?
 
 Thanks.

 It is a bit blurry why the LGPL version could not be used on Apple's store.

 I would not bet my money on redistributing my important app with the LGPL

 After all, there were people who published applications on the Apple store a 
 long, long time ago. They did a port of Qt to iOS on the 4.8 times. And I 
 don't think it was based on the commercial license:
 
 http://www.mediator-software.com/ http://www.mediator-software.com/

I think the big value of the Indie License was the additional add ons like the 
Qt in-app purchases.

I decided to buy an indie license at mid July because I didn’t find nothing 
good as Qt in-app purchase. But now ?!?!

[Interest] How to know if WebView has an error on loading the page

Hello,
I’m using this http://doc.qt.io/qt-5/qml-qtwebview-webview.html 
http://doc.qt.io/qt-5/qml-qtwebview-webview.html for embedding some simple 
pages into the app.
But I don’t know how to check if there was problems on downloading the page.
For example, if the remote url is not available, or if the device is offline, 
the webview just display a white empty page on iOS without notifying the user 
for the error.

Re: [Interest] Subclassing QQmlComponent for use in QML

[Gian Maxera]

Not sure want you need.
If you just need to create your objects from QML, it’s not mandatory to extend 
from QQmlComponent but from QObject.

So, if you create a C++ class derived from QObject called:
class MyNewQML : public QObject 

and you register is with qmlRegisterType

you can write into QML:

MyNewQML {
  ….
}

Re: [Interest] Camera cature ios roated 90 ccw (5.4.1)

[Gian Maxera]

I got the same problem on iOS when I capture an image.
The problem arise on iOS because iOS do not rotate the image but it store into 
EXIF metadata how it should be rotated and orientated the image for visualising 
it.
But the Image item of QML (in my case) ignore the EXIF metadata for orientation 
and hence you see the image rotated.
My trick was to rotate the image using iOS api.
I’m sorry, I don’t have the code here. Later during the code I’ll send you my 
function for doing that.

Ciao,
Gianluca.

[Interest] ListElement value cannot be a property script

[Gian Maxera]

Hello,
I have a ListElement as following:

ListElement {
name: Alexanderbrfont size=\1\+qsTr(Sales Executive, 
Russia)+/font

And QML complain to load it because I cannot use script as property value for 
ListElement.

But if I write the following:
ListElement {
name: qsTr(Alexanderbrfont size=\1\Sales Executive, 
Russia/font”)

QML can load the ListElement and there no more error.
But I would like to don’t include into translation text the HTML tags and text 
that don’t need to be translated.
So, I can solve the problem and have something similar to the first one that 
comply with ListElement requirements ?

[Interest] How to export text to translate for translators ?

[Gian Maxera]

Hello,
ok for translating the text and generate translations unit to insert into the 
app I’ll use Qt Linguistic. Until now fine !
But a step before that, is to create a document to send to translators and 
collect those translations.
So the question is how the translators can see the text to translate ?
They are not developers, I cannot ask to them to install Qt because Qt requires 
a development environment. So, it’s not reasonable to a non developer person to 
say: please install Visual Studio (or Xcode) and then install Qt … that in 
total will occupy on your computer a lot of Gb :-S and then use Qt Linguistic.

So, what’s the best approach ?
Is there a way to deploy only Qt Linguistics ? or a way to export the text to 
translate in a format readable without Qt ?

Thanks,
Gianluca.

Re: [Interest] Extract only src attribute of an image tag into XmlRole with XPath functions

Hello Federico,
the problem is that the img tag inside the description has been escaped :-(
So, I cannot access it using a query path :-(
If you look at the content of description so can see that instead of having:

I have the image escaped:
descriptionlt;img src=“ … /description

XmlRole { name: “img”; query: “fn:somefunction( description/string(), ‘some

But no idea what to use, not event if it’s feasible.

 I don't know If it is possible to apply some kind of transformations over the 
 XML or if there is a specific way to handle this case. Depending on the way 
 you are you receive the full XML, you can try to call a JS function to polish 
 it via the replace() http://www.w3schools.com/jsref/jsref_replace.asp 
 function and then set the polished XML to the xml property. That's not 
 certainly the most efficient approach but it could work.
 Just my two cents.
