@ChrisA said in Qt Creator takes CPU 100% when IDE terminates: Any resolution? I'm having this on macOS with Qt Creator 19.0.2. After quitting, Activity Monitor shows CPU at 100% until I force-quit. Same issue here on macOS with Qt Creator 19.0.2 — following this thread in case anyone finds a fix.

@Chris-Kawa said in QPalette is useless after QSS: QSS does not overwrite palette. Of course it does not change the current palette itself. But it changes the current appearance of the active palette by adding modifications to it. If that makes sense. This is what I mean above.

Under Enable touch gestures, Microsoft writes: https://support.microsoft.com/en-us/windows/touch-gestures-for-windows-a9d28305-4818-a5df-4e2b-e5590f850741 Note: When touch gestures are enabled, three- and four-finger interactions in some apps might not work. To continue using these interactions in those apps, turn off this setting.

We started with this style sheet (it's been a while ago, so it might have changed in the meantime): https://github.com/colinduquesnoy/qdarkstylesheet We just grabbed the .qss and the necessary icons from that repository. This was because we wanted to have a dark style (and at first used the default light mode of Qt on Windows). Qt didn't have a dark mode back then. Then we searched for all the different colors that are used. Here are the colors we have found (and maybe even changed some colors): BACKGROUND ----------- Light #4D545B #505F69 (unpressed) Normal #31363B #32414B (border, disabled, pressed, checked, toolbars, menus) Dark #232629 #19232D (background) FOREGROUND ----------- Light #EFF0F1 #F0F0F0 (texts/labels) Normal #AAAAAA (not used yet) Dark #505F69 #787878 (disabled texts) SELECTION ------------ Light #179AE0 #148CD2 (selection/hover/active) Normal #3375A3 #1464A0 (selected) Dark #18465D #14506E (selected disabled) Each occurrence of a color we replaced with %1, %2, %3, etc. in the style sheet. If we want to apply either light mode or dark mode we load the style sheet as string and replace the dark or light colors with QString::arg() and then apply the style sheet.

@Christian-Ehrlicher didn't seen that at first but was wondering about the table containing all default icons and their names and changing their size.

dear op: there is a difference in TCP syn reject vs tcp syn drop. The reject would send a (nak) signal back.. the dropping would leave the sender unknowing whether the recipient ever received the syn signal in the first place. I think you need to re-look at your methodology for determining whether the server is "available". I'm less inclined to believe it is a QT framework bug. You may need to do a deep dive on the QAbstractSocket::SocketError type and understand exactly why each of those conditions can occur, and react accordingly.

@SGaist oooohh right. oversaw the %1 in the path. yeee gonna put something there for the user warning when i got the other things done!

@Simmania With Qt Creator 20 you can use the ACP Client to connect to an ACP Agent like Claude Agent, Codex CLI, or OpenCode and do any AI work. The ACP Client plugin is part of the OpenSource Qt Creator.

@SimonSchroeder Ahh ok that's much easier than what I am doing now. Thank you!

Alright, thank you for your suggestion. I'll give it a try

So it's the windowsvista style. I can reproduce it but no idea how to fix it. You might create a bug report -> bugreports.qt.io

Or, more likely it was the dumb mistake of doing a quick hack for testing, which deleted my test object...

HoverHandler has a point property which has a position property. Alternatively since you are implementing your QQFBO in c++ you can override hoverMoveEvent and handle it there (after calling setAcceptHoverEvents).

@jeremy_k said in Qt Widgets or Qt Quick/QML for this application?: @Simmania said in Qt Widgets or Qt Quick/QML for this application?: plus the OSG stuff This might be a misunderstanding. The Qt Quick 2 scene graph isn't OpenSceneGraph. Sorry, I ment the QSG.

To add to @jeremy_k KDE folks also implements that technique in their libraries/software.

@JonB said in Need a canvas like widget: QMainWindow is a containing widget with a complex layout as shown in the pic. You could create something like it yourself with parent-child widgets and layouts --- so it is not "magic" --- but it's convenient to use it for just the layout you want. Make the central widget be whatever for your canvas and its relative coordinates will be used for anything you place on it. The menu and status bars will not overlap or interfere with its coordinates. Well, as it turned out, I did already have a QMainWindow, but wasn't aware of what it actually provides, so I got mself a QMainWindow and then explicitly created a QMenuBar inside rather than using the already provided w->menuBar(); (*w is my QMainWindow). I now do w->setCentralWidget(new QWidget); Canvas *Drawingarea = new Canvas(w->centralWidget()); and Bob's my father's brother. Reading (in Germany we have a saying that "Whoever can read has a definite advantage") the documentation about QMainWindow, it is actually exactly what I need!

@AJEJE Qt widgets will do the stuff you mention. For 2D editing you have QGraphicsScene. Qt has 3D stuff but I'm not familiar it with or how to do an "editor", though presumably it can. I also don't know whether QML would be of interest to you, but it's a completely different paradigm from traditional procedural programming. All Qt stuff is cross-platform (Windows/Linux/Mac). You would probably want to write in C++ if you come from C#, though Python is also available.
