Re: [Development] [RFCs] Migrate from GCC MinGW to LLVM MinGW

[Yang Fan]

 I believe the primary difference lies in the C and C++ Libraries. MINGW64
uses msvcrt and libstdc++, while CLANG64 employs ucrt and libc++.

Re: [Development] [RFCs] Migrate from GCC MinGW to LLVM MinGW

[Yang Fan]

I wanted to point out that MSYS2 offers precompiled packages of Qt6 in four
different environments: CLANGARM64, MINGW64, CLANG64, and UCRT64. In my
opinion, simply switching among Qt's official precompiled packages and
toolchains doesn't seem to carry significant benefits.

Instead, learning how MSYS2 provides precompiled packages for multiple
toolchains seems to be a more fruitful approach. Alternatively, just
providing support such as mkspecs for users to compile on their own could
also be sufficient.

 Correct, all of them come from QtWebKit.

 Anyway, there's no plan on further updating QtWebKit from upstream because
 upstream WebKit is no longer cross-platform.

 I have no clue about the bootstrap symbols, but all of the ICU symbols are
 documented to be stable in icu-project.org and have been for some time.

Re: [Development] Ios: Launch image is always black

[Yang Fan]

Hi,

I just want to know how to write the custom plist for customized
LaunchImage file names?


On Sun, May 11, 2014 at 1:20 AM, Christophe Thomas oxygen77...@gmail.comwrote:

 Dear all,

 I've configured my pro file in order to add to the Bundle the icons and
 launch images.

 I use the system:

 IconFiles.files=$$system(find $$PWD/icon/ios/ -name '*.png')
 IconFiles.path=./
 QMAKE_BUNDLE_DATA += IconFiles

 icon/ios folder contains both Icon-*.png and Default-*.png files

 It works fine with the icons but not with the launch image.

 Searching the web I found BUG-31431 and the resolution that consists of
 forcing a blank default-5...@2.png in the default_post.prf script. I
 understand reading the comment of the bug report that if we want to have a
 custom image we need to use a custom plist and define a different name for
 the image from the default one.

 Is my undertansding ok ? Is there another way to have a custom image as I
 don't have currently a custom plist file? Any plan of modifying this ?

 Hi Yang and all,

 I'm curious about how to scale for high DPI on Android as well, so I did
 some reading of the Qt source today.

 On iOS and OSX, scaling is handled by implementing devicePixelRatio() in
 the respective QPlatformWindow implementations. On Android, the equivalent
 concept seems to be density:
 http://developer.android.com/reference/android/util/DisplayMetrics.html#density.
 Right now, the Android code uses the scaledDensity for certain things:
 https://bugreports.qt-project.org/browse/QTBUG-29674, but not for
 implementing the devicePixelRatio.

 Can someone with domain knowledge weigh in on how scaling is supposed to
 work? Otherwise, I'll experiment with hooking up devicePixelRatio to
 DisplayMetrics.density and report back.

 It is on Linux. I've had the build working for two years now. In fact, I'm
 running Qt Creator 3.0 built with ICC right now.

 On Mac, I'm not sure if I've upstreamed all the patches yet. ICC 14.0 is
 the
 first in a while to support OS X. I did some work when I got access to the
 beta
 and I did make sure it still compiled a few weeks ago, but I might have
 pending patches left.

 On Windows, I haven't tested in a long while. I don't want to support
 Windows
 myself, so you'll only get a best-effort solution from me: if you post the
 compilation errors here or to bugreports.qt-project.org, I'll see if
 they're
 easy to fix. If they're not, I'll close with Out of scope. If you need to
 ensure it's working, please contact your sales rep -- that means I might
 get
 another pair of hands to help me track down the issues.

Open your ~/.ssh/config, add some configurations like this:

Re: [Development] Qt 5.2rc1(165) iOS problems

[Yang Fan]

According to my test result, RC1(167) works, but some critical bugs exist.
1. Flickable based element such as ListView may hang when scrolling fast,
sometimes but frequently, seemly Android port has the same issue, but
desktop editions are ok.
2. can't make the window maximized or full screen by
QMainWindow/QQuickView's showMaximized() or showFullScreen() method, did I
miss something?
3. qml based application draw clipped incorrectly when the orientation is
changed from portrait to landscape, but the properties that indicate the
window size are right.
4. animation draw performance is much worse than beta.

Hope these bugs could be fixed in the final release.

  Hello All,

 I just downloaded the latest 5.2rc1(165) snapshot and tried to build a
 simple QML app on iOS simulator.

 The app is built and ran ok, but any actions I try to perform (such as
 clicking a MouseArea) does nothing.

 Also, linkage time is significantly longer than in the beta (it takes 2-3
 minutes to build the app now, while in beta it took a few seconds.)

 Here’s the QML I tried:

 import QtQuick 2.0


 Rectangle {

 width: 360

 height: 360

 Text {

 id: _text

 text: qsTr(Hello World)

 anchors.centerIn: parent

 }

 MouseArea {

 anchors.fill: parent

 onClicked: {

 _text.text = Ouch!

 }

 }

 }


 Is QML for iOS supposed to work in RC1(165) ? Any ideas what’s wrong ?


 Thanks In Advance,

   Ynon

What's the problem of iOS package, does the source code issues stop the

 Hi all,



 Unfortunately there were again some issues with qt5.git integration:
 openSSL -folder was missing in (one) CI machine and that’s why integration
 failed L Why it was missing is totally unclear, same stage was executed
 in that same machine couple of days ago without problems…



 Folder is now added and integration restarted. But that means we don’t
 have packages for testing and verification this morning. Hoping everything
 goes OK now and we could have new packages with new content later today…



 We will keep you informed…

 http://qt-project.org/wiki/Qt500RC1KnownIssues
 If you find anything that is not already there, please feel free to
 update the wiki with your findings.

 Just to clarify a bit more:
 The packages mentioned by Rafal are the ones we had hoped to be ready for
 the RC, but due to the issues we have found so far (listed here
 http://qt-project.org/wiki/Qt500RC1KnownIssues) it does not look like we
 can use these packages for the RC.

 We therefore suggest to spend the next hours trying to improve the current
 status, and generate new packages for the RC this evening. For this to be
 successful, it is very important that we only push changes that are
 important for the RC, to stable right now.

 If we succeed, we can have RC packages ready tomorrow morning CET.

Re: [Development] QtWebkit from Qt5 couldn't display Chinese characters correctly on Windows

[Yang Fan]

Hi,

Thanks for your reply.
I created a bug at https://bugreports.qt-project.org/browse/QTWEBKIT-383.


On Wed, Nov 28, 2012 at 3:26 PM, Hausmann Simon simon.hausm...@digia.comwrote:

 Hi,

 If the issue appears only with QtWebKit on Windows but not with the same
 version on Mac or Linux/X11, then I think it is very unlikely that it can
 be resolved with a setting. These things should work out of the box with Qt
 (like you expect).

 It could be an issue in WebKit, maybe ICU or something in the font
 database causing us not to find fonts.

 Traditionally these kind of problems usually are either a text
 encoding/decoding  problem, a problem with shaping (unlikely) or a lack of
 fonts (or us not finding them).

The example under qt5\qtbase\examples\widgets\richtext\textedit seems OK.
It could input Chinese characters, opens a text file contains Chinese
characters and displays correctly.

  Hi list,
 
  I'm writing a network program which runs on MS Windows, Linux and Mac OS

  All things look good but it seems that the network performance needs
  improving. I see the QtNetwork module especially the
 QNetworkAccessManager
  class which I'm mainly using in my program  is implemented using cross
  platform select model, this model is designed for easy using but not for
  good performance such as low latency and high throughout, every Operating
  System provide a special socket/IO model to let applications have good
  performance, for example, MS Windows provides IO completion port model,
  Linux (= 2.6 kernel) provides epoll/AIO model, BSD/Mac OSX provide
 kqueue
  etc. So I want to  provide my customized NetworkAccessManager class, but
 I
  don't want to modify the Qt's source code since I will use Boost.asio
  library which depends on Boost library, a very big library that is not
  suitable to include in Qt as a 3rd party library. I wonder if your guys
  could modify the QNetworkAccessManager's method declaration(get, post,
  put...), make them be virtual, so that I can derive a subclass and modify
  the implementation. The reason I need a subclass of QNetworkAccessManager
  not a new class is, I also want my class could be set as the network
 engine
  of QtWebkit.
  Feel free to reply if you have any other good idea.

[Development] Proposal: virtual method of QtNetwork interfaces

[Yang Fan]

Hi list,

I'm writing a network program which runs on MS Windows, Linux and Mac OS X.
All things look good but it seems that the network performance needs
improving. I see the QtNetwork module especially the QNetworkAccessManager
class which I'm mainly using in my program  is implemented using cross
platform select model, this model is designed for easy using but not for
good performance such as low latency and high throughout, every Operating
System provide a special socket/IO model to let applications have good
performance, for example, MS Windows provides IO completion port model,
Linux (= 2.6 kernel) provides epoll/AIO model, BSD/Mac OSX provide kqueue
etc. So I want to  provide my customized NetworkAccessManager class, but I
don't want to modify the Qt's source code since I will use Boost.asio
library which depends on Boost library, a very big library that is not
suitable to include in Qt as a 3rd party library. I wonder if your guys
could modify the QNetworkAccessManager's method declaration(get, post,
put...), make them be virtual, so that I can derive a subclass and modify
the implementation. The reason I need a subclass of QNetworkAccessManager
not a new class is, I also want my class could be set as the network engine
of QtWebkit.
Feel free to reply if you have any other good idea.

Regards,
Fan Yang

Re: [Development] Status of WP8 port

[Yang Fan]

Nobody knows. Since Nokia sold Qt, the development progress is slower
and slower and slower...

 What's the status of Qt 5 on WP8? Last I remember, a feasibility study
 was being carried on. What was the outcome?

 If you happened to read Chinese (which I assumed you do), [1] provides

Re: [Development] Qt 4.8.3 released

[Yang Fan]

I built both x86 and x64 version, both have the problem. Also I tried
to test on Windows, it seems that there
are some other problems, eg .pro project file format is not fully
compatible with early version (4.8.2 or lower).

 Does your app uses katepart? Is it related to editing? Are you building in
 amd64?

 We (Debian Qt-KDE maintainers) have sen some segfaults with 4.8.2 + a
 patch
 taken from a 4.8.3 commit.

Re: [Development] Choosing a new MinGW for Qt 5

[Yang Fan]

Yes, I was trying make -j option under the msys environment one or two
weeks ago, and it gave incompatible path string and broke my building
process. My msys was installed through official MinGW installer or from the
Git for Windows project, both have the same problem.

 I forgot to say we now have SEH exception support, which is the best

  All those MinGW and forks contain mingw32-make.exe util which does have

 Are you sure of that? I remember reading a thread in the mingw.org
 mailing list in which Earnie Boyd explained MSYS did the path string
 translation and in most cases it worked fine. Or are you talking about
 the cases where it fails? (recursive spawns, overinterpretation of the
 path string, etc)

TDM/MinGW-builds projects provide -m32/-m64 option to generate 32bit/64bit
binaries using the same package, I don't know if qmake supports it.

 My suggestion on how to proceed is to choose one that offers the
 following or
 most of the following:
 
  - most recent GCC (4.7 preferably, 4.6 if not)
  - *working* GDB and tested with Creator, with Python support
  - large file support, threading
  - zero-overhead exceptions (no SJLJ exceptions)
  - standard win32 headers, if possible using the Platform SDK headers
  - large set of win32 import libraries
  - 32 and 64-bit in one package
  - make with -j support
  - if this exists: can link to .dll directly, instead of import libs
 
 We should choose one version to be the reference platform and work on
 making
 it Tier 1. We shouldn't have two versions, that duplicates work.

 Very ambitious! :)

 Linking directly with DLLs is only possible for MinGW if the DLLs were
 created by MinGW, for all other DLLs you need to create an import library
 (.lib) with the 'dlltool' provided with any MinGW installation (perhaps as
 mingw32-dlltool or similar). Always using Import Libraries ensures that
 the link process is always the same, no matter if the libraries are static
 or dynamic. If you want to link directly with DLLs you would also need
 changes in qmake, most likely, which I think you'd want to avoid.

 Most of the GNU makes released *do* support -j, but they often need sh.exe
 in the PATH to enable the functionality for some reason.

 To satisfy all the requirements above, we might need to compile MinGW
 ourselves. While not impossible, I suggest we actively participate with
 the MinGW community instead to make sure that this is what is released
 naturally from its community.

[Development] A bug of uic.exe in Qt5?

[Yang Fan]

Hi list,

I'm trying to port my application from Qt 4.8 to Qt 5, but I'm stopped at
the first stage, the compiler complains it can't handle the files generated
by uic.exe. It seems that there's a new module named QtWidgets, and several
header files are placed in the QtWidgets folder, but the uic.exe tool
generates the files which include the headers, for example, QAction, QLabel
and so on, still point to QtGui folder. Is it a bug of uic.exe in Qt5? Or
did I miss anything?

 You've probably used the wrong uic. Or your .ui file contains hardcoded
 paths.
