[Development] QTouchDevice in Qt 6 ?

[Development] how to get WinId of desktop in Qt6 without QDesktopWidget ?
Hi, in Qt6 the QDesktopWidget is gone, which I used in QWidget *desktop = QApplication::desktop(); QPixmap pm = QGuiApplication::screenAt(event->globalPos())-> grabWindow(desktop->winId(), event->globalPos().x(), event->globalPos().y(), 1, 1); How do I get the desktop window id in Qt6 ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

You mean as a workaround ? Yes, this is what I did - as a workaround. But my question was about the - in my view - wrong code, where Edward also seems to share my opinion. I assume I should not be forced to us a filter engine when I already can pass a filter to this method (and to be honest I have no idea what the filterEngine does and have no need for filtering) -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] QHelpEngineCore::documentsForIdentifier
Hi, I found myself getting an empty list when using QHelpEngineCore::documentsForIdentifier(id) but getting 1 element when using the deprecated QHelpEngineCore::linksForIdentifier(id). Checking the code I stumbled over something which I believe is a bug: QHelpEngineCore::documentsForIdentifier(const QString , const QString ) does if (!d->setup() || !d->usesFilterEngine) return QList(); so it checks if the new filter engine is active, but I think this is not needed here, since in this code, the filter engine is not used at all, since the filterName is already given as argument. Since I ported older code to the new api but did not call setUsesFilterEngine(true) (which I believe should not be needed when I don't work with filters), this check was hit and I get no results. Am I right ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

I'm not talking about "dynamic linking" (happening at runtime) but only about libXX.a versus libXX.so where https://emscripten.org/docs/compiling/Building-Projects.html?highlight=link#dynamic-linking explains that "By default, Emscripten .so files are the same as .bc or .o files, that is, they contain LLVM bitcode. Dynamic libraries that you specify in the final build stage (when generating JavaScript or HTML) are linked in as static libraries." So I read this as: libXX.so files are still linked in statically, the only difference is how emscripten handles the resolving of symbols. See how https://emscripten.org/docs/compiling/Building-Projects.html?highlight=link#archive-a-files explains "Emscripten supports .a archive files, which are bundles of object files. This is an old format for libraries, and it has special semantics - for example, the order of linking matters with .a files, but not with plain object files (in .bc, .o or .so)." -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] wasm and static vs. shared libs
Hi, I see that compiling Qt for wasm produces .a static libs. This however leads to a couple of duplicate symbols when linking my existing large application. Here https://emscripten.org/docs/compiling/Building-Projects.html?highlight=link#archive-a-files I read "Where possible it is better to generate shared library files (.so) rather than archives (.a) — this is generally a simple change in your project’s build system. Shared libraries are simpler, and are more predictable with respect to linking." so my question is: why does qt/wasm not allow to be built as -shared ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

Seems I have found a solution:
put the include inside an ifdef
in qtbase/src/network/ssl/qsslsocket_openssl11.cpp
#if QT_CONFIG(library)
#include
#endif

I have compiled openssl as static lib only with emscripten.
So in the given path to Qt configure .../openssl/lib I only have
libcrypto.a
libssl.a
Anything else I need to pass to configure to make that work ?

${QTDIR}/configure -xplatform wasm-emscripten -nomake examples \
-prefix ${dir}/qt5-installed -opensource -confirm-license \
-openssl-linked
OPENSSL_INCDIR=/home/pvss/branch_3x/build/emscripten/ExternLibs/openssl/include
\
OPENSSL_LIBDIR=/home/pvss/branch_3x/build/emscripten/ExternLibs/openssl/lib \

-skip qtdeclarative
It seems it has to do with openssl.
Should it be possible to configure with openssl ?

The correct way to use Qt classes forward declared with (and also without) a namespaced Qt build is e.g.: QT_FORWARD_DECLARE_CLASS(QTimer) The problem we had with a namespaced Qt were: using external Qt based libraries, which never tried to use a namespaced build, did not build due to forward declarations, so I had to patch some of them. But then, not all external library projects liked these patches so we'd have to patch them on our own increasing the workload when upgrading ... Also, when using squish you can no longer use a prebuilt version and have to compile squish from sources including also the namespace AFAIR. Eventually we could go back to non-namespaced builds, which makes your life simpler. -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] which branch to use for a fix in 5.9 ?
Hi, I want to create a patch for the 5.9 version, however it's not clear for me which branch to use. This guide http://wiki.qt.io/Branch-Guidelines says: "All bugfixes go into the "most frozen" maintained branch which they are relevant for. " So I assume I should use 5.9 and not 5.9.6, right ? What is unclear is also: "release: the current deep-frozen branch. It corresponds with one actual release and consequently has a name like 5.3.1. It is (usually) created from the stable branch when a release is imminent. It is terminated by a release tag, after which the branch is merged and deleted." especially the last part "...after which the branch is merged and deleted." However there are multiple 5.x.y branches. Shouldn't they be no more ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

I'm just trying this but I get a link failure (error below). Questions: - Does QtWebKit allow to disable Qt-Quick alltogether ? I don't need that.

Hi, trying to build 5.9.1 (from downloaded qt-everywhere-opensource-src-5.9.1.tar.xz) on openSuse 42.2, I get linker errors in the qtmultimedia module, e.g. .obj/qgstreameraudiodecodersession.o: In function `WinCC_OA::QGstreamerAudioDecoderSession::configureAppSrcElement(_GObject*, _GObject*, _GParamSpec*, WinCC_OA::QGstreamerAudioDecoderSession*)': /home/PACKAGES/qt/5.9.1/qt-everywhere-opensource-src-5.9.1/qtmultimedia/src/plugins/gstreamer/audiodecoder/qgstreameraudiodecodersession.cpp:154: undefined reference to `WinCC_OA::QGstAppSrc::setup(_GstElement*)' I found this symbol to be in the qgsttools_p lib but I fear the linker takes the lib from a wrong path. Looking into the qtmultimedia/src/plugins/gstreamer/audiodecoder/Makefile, I find the LIBS definition which I don't understand (Note that I'm building Qt with a namespace/libinfix): LIBS = $(SUBLIBS) -lqgsttools_p -L/usr/lib64 -L/home/abuild/rpmbuild/BUILD/qtmultimedia-opensource-src-5.9.1/lib -lQt5MultimediaWidgets -lQt5Multimedia -lQt5Widgets -lQt5Gui -lQt5Network -lQt5Core -lasound -L/home/PACKAGES/qt/5.9.1/qt-everywhere-opensource-src-5.9.1/qtmultimedia/lib -lQt5MultimediaWidgetsWinCC_OA -L/home/PACKAGES/qt/5.9.1/qt-everywhere-opensource-src-5.9.1/qtbase/lib -lQt5MultimediaWinCC_OA -lQt5WidgetsWinCC_OA -lQt5GuiWinCC_OA -lQt5NetworkWinCC_OA -lQt5CoreWinCC_OA -lGL -lpthread -lgstaudio-1.0 -lgstvideo-1.0 -lgstpbutils-1.0 -lgstapp-1.0 -lgstbase-1.0 -lgstreamer-1.0 -lgobject-2.0 -lpulse-mainloop-glib -lpulse -lglib-2.0 A couple of questions: -) -lqgsttools_p as first argument BEFORE any -L would search for it in my system dirs, which is wrong. -) why is -L/usr/lib64 there (should be a std. path, no?) -) From where the heck comes this path "/home/abuild/rpmbuild/BUILD/qtmultimedia-opensource-src-5.9.1/lib" ? I don't have a /home/abuild directory on my system. This is the ONLY Makefile in the whole Qt tree which contains this path -) -lQt5MultimediaWidgets and others: why are they used here instead of the namespaced/infixed versions, which are also given but later in the line ? I just removed manually all the wrong entries in that line, being now LIBS = $(SUBLIBS) -lasound -L/home/PACKAGES/qt/5.9.1/qt-everywhere-opensource-src-5.9.1/qtmultimedia/lib -lqgsttools_p -lQt5MultimediaWidgetsWinCC_OA -L/home/PACKAGES/qt/5.9.1/qt-everywhere-opensource-src-5.9.1/qtbase/lib -lQt5MultimediaWinCC_OA -lQt5WidgetsWinCC_OA -lQt5GuiWinCC_OA -lQt5NetworkWinCC_OA -lQt5CoreWinCC_OA -lGL -lpthread -lgstaudio-1.0 -lgstvideo-1.0 -lgstpbutils-1.0 -lgstapp-1.0 -lgstbase-1.0 -lgstreamer-1.0 -lgobject-2.0 -lpulse-mainloop-glib -lpulse -lglib-2.0 and with that line it links without errors. -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] Qt / NaCl / emscripten
Hi, I wanted to give WebAssembly a try and wanted to compile wip/nacl with emscripten. However, compilation fails as it seems some files of pepper are missing here, e.g. pepper_55/src/ppapi_cpp/font_dev.cc I tried with 3 different pepper versions (44, 49, 55). None of these could compile since every one was missing a file (not always the same). Can you tell us with which version it should be able to compile ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] QDBusConnection - connect to "catch all" slot ?
Hi, In QDBusConnection there are several connect() methods which check the signature of the signal against the connected slot. Since I'd like to implement a scripting possibility around this, I'd need the possibility to either be able to receive all QDBusMessages (at least from DBus signals) or a way where the slot just gets all arguments via a single QList parameter (from QDBusMessage::arguments()). Is there currently a way to achieve this ? I found qDBusAddSpyHook - probably this is what I'm looking for ? Or what was the reason to have this function ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] QWidget and sizePolicy
In the docs I find: "If there is a QLayout that manages this widget's children, the size policy specified by that layout is used. If there is no such QLayout, the result of this function is used." However in the code I can not find a relation between the sizePolicy and a layout. QWidget::sizePolicy() simply returns what it was given in QWidget::setSizePolicy() A layout itself has no sizePolicy, so this also is strange. Is this probably a leftover and the documentation was not updated or do I miss something ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] Question to fonts and styles
I got a question from a kolourpaint user (KDE painting program) why he can not see the same fonts he finds in e.g. libreoffice. Checking my own system (openSuse 13.2), I see some differences where I hope someone here can answer why Qt does list some fonts. E.g. fc-list finds also these fonts /usr/share/fonts/truetype/DejaVuSans-ExtraLight.ttf: DejaVu Sans,DejaVu Sans Light:style=ExtraLight /usr/share/fonts/truetype/DejaVuSansCondensed.ttf: DejaVu Sans,DejaVu Sans Condensed:style=Condensed,Book but in a QFontComboBox I only get DejaVu Sans and also DejaVu Sans Mono, but I do not get the two above DejaVu Sans Light and DejaVu Sans Condensed both of which libreoffice shows. (This happens with Qt4.8.6 and with Qt5.4.1) Is this because the two mentioned above are just styles of DejaVu Sans ? Intersting is that fc-list also lists DejaVu Sans Condensed as family name, e.g. family: DejaVu Sans(s) DejaVu Sans Condensed(s) familylang: en(s) en(s) style: Condensed(s) Book(s) stylelang: en(s) en(s) fullname: DejaVu Sans Condensed(s) Shouldn't Qt list all fonts as different fonts which are listed with a unique family name ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] QImage miscompilation with gcc
I've found a very strange (and serious) miscompilation of QImage with g++
In qimage.cpp there is a simple line (3584 in Qt-5.3.2):
d-paintEngine = paintEngine ? paintEngine : new
QRasterPaintEngine(paintDevice);
which results in 0(!). The return value of this method QImage::paintEngine() is
then 0 -
which should never happen.
I can reproduce with a slightly modified minimal platform plugin, and only if
it has
a second QImage member, which gets its mImage member assigned.
I have created a very small reproducible example program and I verified that
this only
happens when compiling QtGui with gcc (4.8.3 or 4.9.0), but it does not happen
with clang (3.5.0).
All tests are done on x86/64bit Linux (openSuse 13.2) with a self-compiled
Qt5.3.2 (with a namespace, in debug mode).
I also see the problem compiled with gcc-4.8.2 in release mode compiled on a
CentOS-7
Testprogram/diff attached.
Simply run with ./splash -platform minimal and in case of the bug it prints:
created new QImage paint engine 0x0
returning QImage paint engine 0x0
QWidget::paintEngine: Should no longer be called
QPainter::begin: Paint device returned engine == 0, type: 1
QPainter::setPen: Painter not active
Can anyone please tell me if you can reproduce this ?
Is this really a gcc bug ?
Shall I create a gcc bug report with this example/description or is this much
too large for
a testcase ?

Hi, I have installed qt-opensource-mac-x64-ios-5.3.0-beta.dmg and while compiling my app, I get: no member named 'sslConfiguration' in 'QNetworkReply' which is happening when QT_NO_SSL is defined - which seems to be the case in qconfig.h: #if defined(QT_NO_OPENSSL) defined(QT_OPENSSL) # undef QT_NO_OPENSSL #elif !defined(QT_NO_OPENSSL) !defined(QT_OPENSSL) # define QT_NO_OPENSSL #endif Is there a specific reason why QT/iOS is configured in that way ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

Re: [Development] QPA / QWindow / QPainter
On Monday 10 March 2014 14:43:42 Agocs Laszlo wrote: Yes, one platform window for each native widget and one backingstore per top level window. (where the toplevel's backingstore is the common backingstore for all of its child widgets) QPA (QPlatformBackingStore) does not know anything about paint devices, paint engines and such. It allows you to provide a paint device to the widget stack or whoever performs the painting, that's all. The returned paint device could be a QImage, an OpenGL framebuffer object, a custom device with a custom paint engine doing stuff that has nothing to do with painting, etc. It does not have to be something that holds the actual pixels. The platform plugin must provide a backing store implementation however. (unless it does not care about widgets) To implement your remoting use case, there is most likely no need to complicate things with native widgets. It is exactly the same concept as generating HTML5 canvas code or PDFs or anything else: - Have a custom paint device that provides a custom paint engine which buffers the painting commands. Such a buffer will contain the drawing commands for all the children of a given toplevel. - In the platform backingstore's flush send the commands over the network Or is something, that would mandate the usage of native child widgets, missing from the picture here? yes, I was trying to keep the explanation simple. In fact what I do is to remote the painting commands to a HTML5 canvas, but as some objects shall do blinking, which I do not want to be done via a lot of redraws, I instead create SVG objects which shall be intermixed displayed with what the canvas shows (that is: primitve objects like lines, circles are SVG, widgets are drawn as usual). But to have a chance that the stacking order of the SVG objects and the widgets is still correct, I wanted to create the native widgets as separate canvas objects so that they do stack with the SVG objects. What I think I can do to solve it is to use a global event filter, catch the paint events of the widgets I want to stack correctly and redirect QWidget::render() to a paint device which knows the window id ... or something like that. -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

Do you find any trace of information that it's discontinued ? In any case, each non-top-level QWidget has a link to the top level window (TLW) it's connected to and stores state there. Yes, QWidget has windowHandle() if you mean that. But that does not answer my question. In the QPA API there is no QWidget pointer AFAIK.

Well, it takes a QIODevice as data source, so that shouldn't be a problem (as you stated yourself). As you probably know, there is a feature freeze for Qt 5.3; so changing the API is currently not a good idea. Instead of making QWebSocketDataProcessor public, could you live with the (now private) upgradeFrom() method? This method is actually taking a QTcpSocket and 'upgrades' it to a QWebSocket. well, probably, but it needs the now still private classes QWebSocketHandshake* as argument, so I fear this is also not a solution for 5.3 Do you process the handshake yourself? yes The dataprocessor only takes care of data after a successful handshake has been exchanged. yes, that was my impression. I was just looking for a way to handle the websocket protocol itself when the websocket was already established. It is however a very interesting use case and should definitely be explored further. Can you add a feature request in Jira? I'll do ... https://bugreports.qt-project.org/browse/QTBUG-36952 I see it's currently reading from an QIODevice which should be ok, but what is unfortunate is that QWebSocketFrame::readFrame(pIoDevice); blocks!

It seems that nowhere in the Qt source code the value of QPalette::Mid is being set, apart from QWindowsTheme. In my case, the relevant class is QKdeTheme, which does set a value for QPalette::Mid but only for the QPalette::Disabled ColorGroup. Therefore, for the Active color group the value is defaulting to black. Is this intended behavior or should this be fixed?

Wrong! The order is very essential and can and must be relied on.

Andreas, I'm confirming the QT5 behavior, to be as Martin describe. BUT,
the Qt4 behavior seems to be as YOU recall - no ButtonPress at all for
the fast-enough second click which invoked a DoubleClick event.
I'm not making things up. This is what my testprogram gives.
I attach it here.
I see now the problem with my testprogram.
I also called the basclass implementation, which leads to the extra
mousePressEvent.
(fixed prog attached)
when I just print the events in my implementation, I get:
Qt4:
mousePressEvent
mouseReleaseEvent
mouseDoubleClickEvent
mouseReleaseEvent
Qt5:
mousePressEvent
mouseReleaseEvent

so it's just the extra mousePressEvent in Qt5 which is wrong.

I've discovered that with Qt5 I get a different order of mouse events on a QWidget than with Qt4 (openSuse 13.1 Linux, X11): double clicking a widget results in Qt4 in: mousePressEvent mouseReleaseEvent mouseDoubleClickEvent mousePressEvent mouseReleaseEvent but in Qt5 in: mousePressEvent mouseReleaseEvent mousePressEvent mouseDoubleClickEvent mouseReleaseEvent I tested with Qt4.8.5 and Qt5.2. Is this behavioral change intended, undefined, a bug ? (it results in my app not behaving as before ...) -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

[Development] Qt5.2 application palette
I'm at ec03058fa5b84b4570a2158bf2179f7ba4d83b99 and I see something I can not explain: QApplication app(argc, argv); cerr style: qPrintable(QApplication::style()-objectName()) std::endl; QPalette pal = QApplication::palette(); cerr dark: qPrintable(pal.brush(QPalette::Dark).color().name()) endl; this code tells me the style I use is fusion and the dark value is #00 However using this code extern QPalette qt_fusionPalette(); QPalette fpal = qt_fusionPalette(); tells me that dark is #9f9d9a I was thinking the style defines the default palette. When compiling against Qt 4.8.5 and using -style plastique I get dark as #6a6563 I'm struggling with this as dark is the background color of a QMdiArea and in Qt4 it is really gray as documented, but in Qt5 it's black. -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?
