While in the showMaximized mode, I’m trying to set a background image to my mainwindow by obtaining the size of the screen using
QRect rect = desktopWidget->availableGeometry();
But this returns the size of the screen excluding the taskbar. I read in the documentation that if int screen = -1 then the whole screen would be considered. Where do I specify the parameter? I tried
QRect rect = desktopWidget->availableGeometry(int screen = -1);
and
int screen = -1;
QRect rect = desktopWidget->availableGeometry(screen);
But I suppose the above two methods are syntactically wrong. Could someone please help me in this regard?
Thanks.
