|Subject: [PATCH] Supporting xfce4-panel in dwm
|
|We treat the panel as special window which
|- never has borders
|- never has focus
|- always has y=0
|- is never shown as active window in the indicators
|- is shown on all tags (via config rule)
|
|Which window? "xfce4-panel" - configurable in config.h
|
|=> Might work for other panels as well, if you adapt.
