QWindow not displaying icon.

mrjones

Hello,

My application consists of a single QWindow. It just does graphics rendering so I don't need menus, widgets etc. In some circumstances it is launched as a second window from within another application.

I have added an icon but I can't get it do display. What am I doing wrong?

I have a resource file. I use other PNG images from this file elsewhere, and they work.
The icon itself loads OK :
@
MyWindow::MyWindow()
: QWindow()
, ic(":/img/icon.png")
{
setIcon(ic); // icon doesn't change

QPixmap p = ic.pixmap(QSize(16,16));
p.save("icon.png");    // 16x16 version of icon saved OK.

setTitle("blah");      // this works

}
@

Thanks for any help!

I found a workaround.

If you call setIcon() after show() it works.

Looks like a bug in QWindow, or an undocumented function call ordering.

Hi,

I would say it sounds like a bug (I may be wrong) You could check the "bug report system":http://bugreports.qt-project.org to see whether it's something known and raise a bug with a minimal compilable example showing the behavior.
