QDesktopWidget::.screenGeometry() from a Thread

eKKiM

Hi,

I am trying to get the exact geometry of every screen in a thread (ran by QThread).
It seems that QScreen has not the functionality i want. QScreen::availableGeometry() excludes the taskbar from the geometry.

The alternative is QDesktopWidget::.screenGeometry(screenIndex). However i cannot initiate a QDesktopWidget in my thread.
ASSERT failure in QWidget: "Widgets must be created in the GUI thread."

What is the alternative for this to get the info in a thread?

Kind Regards

Hi and welcome to devnet,

Did you create a QApplication in your main.cpp ?

Yes i did.

And with that clue i figured it out! QApplication::desktop()->screenGeometry(screenIndex); works like a charm.
Tyvm!
