Title: TTrayIcon on KDE4
Post by: celyo on November 09, 2011, 03:53:08 pm: Hi,

I'm developing application that uses TTrayIcon.
I've tested it under windows 7 and Fedora 15 (XFCE) and it works fine.
But when I've tested it under OpenSUSE 11.3 (KDE - transparent oxigen theme) the icon shows in the tray but it paint transparent color as White, i.e. where the icon must be transparent the white color is painted?

Any ideas how to fix this?

Oxygen theme has many problems, at least with QT bindings. You could try for example Plastiqeu theme.

You need to grab gtk2trayicon.inc from SVN and re-build LCL with def "UseStatusIcon"

Finally I solve my problem. Thanks to all of you, for your help!
I've used "UseStatusIcon" but there were some problems and I've fixed them.
Now I want to contribute a patch for gtk2trayicon.inc, could you tell me how to do that?

Post by: felipemdc on November 29, 2011, 11:21:56 am: UseStatusIcon is on by default in Lazarus 0.9.31+ from what I remember.

Please create a new bug item in the bug tracker and attach a patch to it:
