[Bug 2063332] Re: Multiple problems Ubuntu 24.04 with Qt5
Thank you for you answer. It is most definitely a regression in Ubuntu 24.04. I have just tested Ubuntu 22.04 on Wayland, the same Qt5 apps and all is working - keyboard shortcuts - window controls are on the left - window titlebar doubleclick to maximize Not sure if it's Wayland, Qt5 or something else When I try your suggestion with qgnomeplatform-qt5 then: - window controls are on the left [OK] - window titlebar doubleclick also works as expected [OK] - fullscreen window state is remembered and restored properly [OK] - keyboard shortcuts still do not work properly [ERR] Anything else I should try? But obviously the behavior is different from Ubuntu 22.04 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2063332 Title: Multiple problems Ubuntu 24.04 with Qt5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/2063332/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2063332] Re: Multiple problems Ubuntu 24.04 with Qt5
What you describe sounds like an effect of switching from X11 to Wayland, not a regression in Qt. In X11, the window decorations can be drawn either by the window manager or by the application itself. Qt relied on window manager, so the decorations looked uniform. In Wayland, there is no choice, and Qt draws its own window decorations, which may be different from GNOME ones. If you signed into a Wayland session in Ubuntu 22.04, you would likely get the same effect. There is a third-party package which may make things better for Qt applications in GNOME: qgnomeplatform-qt5. After installing it, try running your application with QT_QPA_PLATFORMTHEME=gnome environment variable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2063332 Title: Multiple problems Ubuntu 24.04 with Qt5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/2063332/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Please, - notice that all this functionality used to be working on 22.04. + notice that all this functionality is working on 22.04. 1. Windows controls settings from Gnome are not applied When you set the Windows Title bar buttons to Placement Left, then Qt apps ignore this setting. The default gt4 apps behave properly and place the buttons to the left. 2. Windows actions like double click to maximize from settings also do not with in the Qt5 apps unlike in gt4 apps. - 3. Several keyboard shortcuts are passed differently to Qt5 apps. + 3. Several keyboard shortcuts are passed differently to Qt5 apps. The key "Ctrl+Period" is not passed to the qt app at all The key "Ctrl+~" is passed as "Ctrl+0" The key "Shift+Alt+F7" is also not working This means some different handling is applied in Qt5 apps 4. If you use the env var "export QT_QPA_PLATFORM=xcb" and start the Qt5 app, then it all works properly. The windows controls are on the right side, you can use double click the title bar to maximize and also the shortcuts are working fine. However, in such scenario no app starts fullscreen. It starts in a positioned window (the position is remembered) instead even if you maximized the window before you exited it.
