QSystemTrayIcon hide() crash on mac while I use QTimer to change the icon of QSystemTrayIcon

If you start and end your code section in your post with an 'at' sign ('@') it will look much nicer. That is what the others are asking for.

I have just added in the post above these two signs in the begin at the end. And voila it looks much better.

Sorry, had to do two posts ;-)

there is a wiki page explaining how the editor works :

It may be caused by some internal objects that are no longer available after you hide the icon. I can reproduce the crash on my Mac box.

As a workaround you can replace the call to hide with a single shot timer in your slot like this

@
fSystemTrayTimer->stop() ;
//fSystemTrayIcon->hide();
QTimer::singleShot(0, fSystemTrayIcon, SLOT(hide()));
@

This way the call to hide is delivered after you have left the slot.

EDIT:
I've added this as a doc not to [[Doc:QSystemTrayIcon]] too.

That's out of scope for me. I don't know the internal workings for the OS/2 port, sorry.
