Qt::WindowStaysOnTopHint and full screen
Francky033 last edited by
I have a small problem with using Qt::WindowStaysOnTopHin in full screen.
On Windows 10, for example, windows with this flag are always visible on a GPU intel. On the other hand, on a Nvidia card, windows with the Qt::WindowStaysOnTopHint flag go to the background if I click on the main window.
I need to do a raise() to bring them to the first plan but this has an unsightly effect (screen flickering).
I also tried with the Qt::WindowStaysOnTopHint flag but it doesn't change anything.
I use Qt 5.15.0 and Opengl 4.0

try using the windows winAPI function SetWindowPos.
for Qt4.7, maybe it's the same on Qt5
#ifdef WIN32 // first force to show widget on top most // get win handle of the widget to force focus SetWindowPos(widget->winId(), HWND_TOPMOST, 0, 0, 0, 0, SWP_DRAWFRAME | WP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW); // then unforce to show widget on top most SetWindowPos(widget->winId(), HWND_NOTOPMOST, 0, 0, 0, 0, SWP_DRAWFRAME | SWP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW); #endif
