Reimplemented QOpenGLWidget shows under QStackedWidget.
-
Hi. There's QStackedWidged which stacks QMainWindows, some of them parents reimplementations of QOpenGLWidget, everything shows fine when i try do display them "standalone" , but purpose is to stack window to navigate them next-prev. When I manage those windows by QStackedWidget, whole QMainwindow including parented QOpenGLWidget is dislpayed underneath all rastered content, attributes like ALWAYSSTACKONTOP seems to not work with stacked structure, when I "unparent" opengl content - it shows correctly, but then I must reproduce background because then opengl windows display opacite content, this affects performance , framerate decreases about 10-20% when i reproduce underlaying background of containing QStackedWidget in opengl paingGL() .
in fact - I found strange solution - it removes consequence but doesnt resolve problem, after showing window with parented qopenglwidgets i provide this code:
<code>
QMainWindow* mw=new QMainWindow(currentWidget());
mw->setFixedSize(1,1);
mw->showFullScreen();
update();
mw->hide();
mw->deleteLater();
</code>
after that window appears on top. The issue appears on Android-compiled, IOS has not this issue. Maybe someone has some experience with that issue? -
Hi,
Can you show a picture of what you get ?

@SGaist sorry, but I'm not allowed, it look like ALWAYSSTACKONTOP attribute is rejected, all OPENGL content is stored under all rastered content.. thanks :)

it looks like platform-dependent specific issue, because it's only android's problem. i deducted that when last-child is openglwidget problem persists, but if last parented is raster widget-it content appears on top
