Hi,
I have figured it out.
To have the icon displayed correctly on task manager in KDE4, two points:
--you need to have the icon file (.xpm or .png) in folder /usr/share/pixmaps
--the icon file name has to be all lowercase!
Thanks,

Hi,
We are using KDE 4.10.4.
I have one question about the Task Manager widget
(X-KDE-PluginInfo-Name=org.kde.plasma.taskmanager).
When I add the Task manager widget to my panel, any applications I
run(actually our own application) will not show the application's icon
we specified in its .desktop file.
Instead, it will just display the same system icon (X with a circle)..
I already checked all below:
--Make sure the name of the .desktop file matches what the application
sets as WM_CLASS window.
--Make sure that what's set as WM_CLASS makes sense and isn't
something generic (e.g. "java").
--Adding a StartupWMClass key to the .desktop file if the above can't
be done (with the value what's actually set as WM_CLASS).
As you know, none of those are strictly KDE-specific, it's about how
an app is supposed to announce itself to a Linux desktop.
By doing the above, I got it to work in Gnome3, but still can't get it
to work in KDE4.
Here is an example:
I have an application called "pet". I placed a file called pet.desktop
under /usr/share/applications.
The content of pet.desktop looks like:
[Desktop Entry]
Terminal=false
Name=pet
Exec=pet
Type=Application
Icon=/usr/share/icons/pet.xpm
StartupWMClass=pet
When I run "pet" from terminal, the icon shown on the Task manager is
not my pet icon. Instead it is the general system icon (X with a circle).
Any suggestion will be highly appreciated!
Thanks,
Zaiwen
