@J-Hilk I just tried that. It's the same as no debug. There is a visible blank background before "Hello World" shows up if I didn't add a QLabel in QtClass constructor. Thank you!

@Rufledore I don't think you can use Qt library calls for TCP/serial port without being in a Qt application. As in, they don't work properly, as you have discovered. They need parts of the Q(Core|Gui)Application-type architecture.,

@Alfie-Anil You could actually search by yourself... https://doc.qt.io/qt-5/qtquick-codesamples.html

@ManiRon Check whether there is a newer version of the graphics driver for your laptop/graphics card (integrated graphics).

@Ahmed-Zeid Use Layout For your inside controls of ScrollArea then Put Your ScrollArea in Vertical Layout

@Dramcryx What should show-decoration-selected do? There is no style property with this name. Try ::item:selected and the other suggestions. If these don't work, you can't do it with style sheet and you need to change your item or your model directly

@orio great. Worked for me as well!

The problem is the OS - until the OS does not tell us that the widget is really hidden or resized we have to wait. And all this stuff is async.

Hi and welcome to devnet, The idea is to find whether the installation of the two new softwares altered the PATH environment in such a way that DaVinci Resolve fails to find the required dependencies. If so, remove these paths from your PATH environment variable and start DaVinci again to check.

@akrilax34 said in Scene3D Widget example crash against 5.15: Anyone from Qt3D team please ? This is a user-driven forum. I doubt there are many people from TQtC here around. The official way to reach developers is the bug tracker.

Thank you! It solved the problem.

@mchome For compiler warning flags, you must edit the .pro file (QMAKE_CXXFLAGS). For editing warning flags: Tools > Options... > Code Model > Clang Code Model > Manage... button.

@jsulm said in How to use this library ?: I would not recommend WSL2 as then it would be a Linux binary, not Windows. Yes, that's quite right sir! Just thinking about the whole development under Linux, but that's not the case.

@J-Hilk said in [Qt Installer Framework] Run a batch file during uninstallation: Ok, I found the correct file. seems like I abandoned the shell script on deinstall and went directly to this entry Component.prototype.createOperations = function() { ... component.addOperation("Execute","echo", "do nothing","UNDOEXECUTE","rm", "-rf", "@HomeDir@/Desktop/MyApp"); } This worked! Thanks a ton! Initially, I didn't notice the neat little trick you did by doing nothing in the Execute part.

@rifky said in cant passing 'QList<QSqlRecord>&': const QList<QSqlRecord> recs Const reference is const QList<QSqlRecord> &recs
