How to change background color of balloon message for QSystemTrayIcon
How can I apply stylesheet rules to the balloon message that is displayed using the QSystemTrayIcon::showMessage() function? My main goal is to simply change the background color but I'd also like to be able to modify the border and font and use a custom image for the close button.
background:rgb(85, 84, 120);
border:1px solid rgb(79, 79, 79);
color:rgb(0, 0, 0);

Does anyone know how to apply the css rules above to a balloon tip? Obviously the code above doesn't work and I've also tried applying those rules to QBalloonTip but it doesn't have any visible effect either.
I doubt the ballon message is stylable at all.
On Windows system function Shell_NotifyIcon() is used
On Mac OS X "growl":http://growl.info/ (a 3rdparty framework) is used
Only on Linux and WinCE the balloon seems to be drawn by Qt itself.
The application I'm developing will only be used on Linux so it won't matter if it's not cross-platform compatible. I've looked at the source of the QBalloonTip class and it appears that the background is set with the code below.
QPalette pal = palette();
pal.setColor(QPalette::Window, QColor(0xff, 0xff, 0xe1));
How can I replace the QBalloonTip constructor with my own code? I've tried to reimplement the QSystemTrayIcon::showMessage function but to do so I would also need to reimplement QSystemTrayIconPrivate::showMessage_sys and QBalloonTip::showBalloon. Unfortunately I'm not entirely sure how to accomplish this.
No need to reimplement QSystemTrayIconPrivate, just copy it's stuff to your own method and use a subclass or modified copy of QBalloonTip.
