General and Desktop

@SGaist Well the table is the report :) I have found the way to do it , I'm not sure if it is the correct one, I have sublassed a QSqlQueryMOdel I created a QMap<QModelIndex , QVariant > editedValues that is appended by a overriden setData (which also take care of DB value update) than an overriden data() checks if the index is among editedValues and if it is it returns the value or else it gets regular value from QSqlQuery::data() .

Hi, The QtMultimedia module has been completely rewritten for Qt 6. There are lots of things that have changed from a design point of view. I currently don't know if this support was removed or not yet re-implemented. I would recommend checking the bug tracker to see if there's something related to it.

@QtUser17456 said in Inherited project with libzip.: C:/Program Files (x86)/GnuWin32/lib/zlib.lib Only a though/possibility. Program Files (x86) is usually for 32-bit stuff under Windows 64-bit, but the rest of your compilation is/might be for 64-bit? Is this a 32-/64-bit mismatch?

@DungeonLords As @JonB said, you need to reposition to the beginning of the file. You can use: file.seek(0); or file.reset();

@Depositc29 please make it complete that way it ensures that we are all working with the same code.

@Andy314 Ups, I found the soltuion: pMdiArea->setActivationOrder(QMdiArea::ActivationHistoryOrder);

Hi @kiozen, I am using Qt creator on windows. Please let me know how to run a application with ASAN on qt

@JacobNovitsky Just so that you understand why only changed source files are recompiled you need to understand three things: qmake creates a Makefile from your PROject file. (So does cmake in many circumstances). Make is a tool designed to reduce compilation times, something about which you have been vocal before, using the rules in the Makefile to minimise what is recompiled and/or relinked. The compiler (linker) can only issue warnings about source code (objects and libraries) if it is compiling source code (linking object files). Since changing any source code file will change its corresponding object file, and the output executable depends on all its input object files, the linker is almost always run by make in the Qt environment. You should be striving to make code in which no warnings are issued at all. This is why @J-Hilk suggests -Werror.

@SGaist said in building Qt MYSQL driver for MAC OS: QT_DEBUG_PLUGINS I will try that but I did find that rebooting apparently solved the problem. I did that after cleaning and rebuilding failed to resolve the issue. Thanks, your quick response is appreciated.

@Christian-Ehrlicher said in Creating a Qt static c++ library for non-Qt c++ application: @SGaist This will not work as the op exports a class derived from Qt (at least this is my guess) but yes, this can be an option. But as already discussed there are only a few Qt classes which work without a Q(Core)Application or a running event loop. You can abstract this all away and add a wrapper class which convrts between Qt and plain c++ but this is cumbersome and still does not fix the event loop problem. 100% agreed, it was just to propose a possible solution but it clearly makes things more complicated that way.

SQLCipher has 3.44.2 in it's repo. And they also provide commercial support so...

@Christian-Ehrlicher thanks for the help, I will look into it. One more question, I'v used QMenu's paintEvent for round corners. The problem is that the resulting round corners are not properly smooth. I've used QRegion and QPainterPath in the paintEvent to set menu's mask using setMask.

@skeud said in Qt build failed on .rcc/qmlcache/quicktooling_component_qml.cpp: do you know if there is an option to avoid qmlcachegen? I don't know. But the crash could be due to anti-virus software blocking this executable.

@Paul-Colby I've released the module under BSD-3-Clause (the same as CMake, itself). Contributions more than welcome :) Great! I'll give you some feedback when I'll add it to a small kit of mine with the same license to be installed in Linux systems, as support for some applications I made. Thank you again for this!

@StudentScripter When you set an item in the model, the model becomes the owner of the item and thus controls its lifetime. If calling removeRows would leave the item(s) it contains intact, you would just have a memory leak by now.

Wow a lot of oportunities. Thanks a lot. I will check this out. Sorry, I was really locking into the docs but wasn't able to find the related constructs. On the other hand I have to explain, to my defense, I have not constructed that specific ListView myself. It is code I took over.

Apologies, this is a known issue, the application-integration method using the QML InputPane has to be used with Wayland, desktop integration won't work, see bug report The docs do also say application integration is mandatory in environments where there is no support for multiple top-level windows. That will teach me to RTFM!

@JonB You are absolutely right! I was confused between the QGraphicsView and the QGraphicsScene. I just realised that when I was playing with my POC. Actually, what change the size of the QGraphicsScene is done in another part of my code and is called later. If I recalculate the sceneRect according to my needs and call setSceneRect(), when my window is resized, everything works as expected. Sorry for the inconvenience.
