Thanks. Now I think I manage to do that.

@Pl45m4 said in Custom Widget not showing in layout: always returning QSize(width(), height()); doesn't feel like the best solution ;-) I guess that QPushButton uses the actual text displayed (plus some padding) to calculate the size hint. QFontMetrics might help here.

@Pl45m4 said in Custom widget using and extending Qt's pImpl: It was just about the naming?! Is this the way? :) I would say yes.

Can anyone share sample code for qlistwidget or qlistview?

@JonB Thank you for the answer this might be helpful i'm gonna try this out

The smoothing done for the antialiasing will not be the same for all colors.

@SGaist Wow thank you very much! I fixed with pt.setClipPath(path2, Qt.ClipOperation.ReplaceClip) Some part of total code: progress_filled_width = self.value()/self.maximum()*self.width() pt.setClipPath(path2, Qt.ClipOperation.ReplaceClip) for i in range(100):

Any idea?

@jsulm I think this is for C++, I don't know how to use it on Python?

Hi I don't think Qt stylesheet supports even half of this #style-9::-webkit-scrollbar-track { -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3); background-color: #F5F5F5; } so you best bet is to dig into https://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qscrollbar and see how close you can get it.

Well, huh. I thought I tried that one with the bigger project before, but it does work with the test program here, so that must have been something else. Thank you for your assistance.

@Burke212 change setup(); CWC = new customWidgetClass(); to CWC = new customWidgetClass(); setup(); hopefully you did initialize CWC as nullptr, otherwise that would have crashed in release mode 10/10 times.

Finaly I have finished my little example! Previous version have been really buggy in items move. So I have to subclass from QAbstractItemModel. Many thanks to @Patou355 with his solution. NB I haven't deal with mousePressEvent() yet.

Why do you have your plugins and application all in the same project ?

@Valveware said in Promoting to custom widget in QtDesigner '*.hpp' no such file or directory [cmake]: file(GLOB_RECURSE QT_MOC RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} FOLLOW_SYMLINKS include/dashboard/*.hpp) Ok that looks like it would indeed moc your cameraframe.hpp.. So that's probably not the issue. Can you share the build log from gcc? And also the ui_main_window.h file as well as ui_cameraframe.h?
