|Subject: [PATCH] Supporting xfce4-panel in dwm
|
|We basically treat the panel as special window which
|- never has borders
|- always has y=0
|- is never shown as active window in the indicators
|- is shown on all tags
|
|Which window? "xfce4-panel" - hardcoded by window name in dwm.c.
|=> Should work for other panels as well, if you adapt.
