To check, I just dl'ed puppy linux and booted off the cd (w/out installing
it)
and brought up the window manager.
First I looked at the default terminal's behavior (rxvt); when I stow
the app, it shows the app's icon.
Then I made a copy of the rxvt binary in /tmp and called it 'erco'
and ran it as /tmp/erco.
The terminal opened, but when I stowed it I got a red 'X' in the
application bar at the bottom of the screen as I kinda expected.
This would seem to show the app isn't setting its own icon.
Next I searched the disk for rxvt with 'find / | grep rxvt' to find
the icon being associated with it, which in my case found (among other
things) /usr/local/lib/X11/mini-icons/rxvt.xpm
So I made a copy of that file in the same directory called 'erco.xpm':
( cd /usr/local/lib/X11/mini-icons; cp rxvt.xpm erco.xpm )
..and when I executed /tmp/erco and stowed it, this time I got the rxvt
icon in the dock.
So pretty sure it's just an install step for your app to put your
xpm file in the correct location for the window manager to find it,
with a name that matches the name of your app. See the above link
standard for naming details.
I believe the reason for this is so that the user can change the
overall desktop theme, and thus have different icons associated with it.
