Hi to all!

I use TrayIcon component, but there is no transparency on icon for
linux/gtk2.
So I have these results:
There is no problem under win32 (icon is transparency).
I have no trayicon under win32/gtk2 at the same project.
And i have non-transparent icon (there is a white square at
background) under Linux/gtk1 and Linux/gtk2.

Any ideas to fix this problem?

To solve this problem, rebuild Lazarus LCL with option
-dUseStatusIcon, to use transparency in trayicon.

But after that i have no icon in tray at all. I spent some time with
tests and learned that fEmbedded property in
lcl/interfaces/gtk2/gtk2trayicon.inc is always False (in my case),
when LCL compiled with UseStatusIcon option...
So i have wrote little workaround. Maybe it's not correct (I'm newbie
in programming ), but it works for me - icon in tray is transparent
now.
Code: [Select]*** gtk2trayicon.inc      2009-04-19 06:59:22.000000000
+1300
--- gtk2trayicon.inc.1  2009-11-07 04:13:37.000000000 +1200

    TrayIconHandle.Show;

    if TrayIconHandle.fEmbedded then
      Result := True

      Hide(ATrayIcon);

Amazing... 2 years later this patch is still valid. I applied it to
Lazarus 0.9.30 in  Linux.
Thanks.

I applied it a few days ago to Lazarus SVN
