Best viewed with vim5, using ts=4

wmgeneral was taken from wmppp.
|
||
|
|
|
||
|
|
It has a lot of routines which most of the wm* programs use.

|

|
|
* Pulled createXBMfromXPM into its own file, because it's the same in
|
||
|
|
both -gtk and -x11.

|
11/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
|
||
|
|
* This is based on wmgeneral-x11.c (formerly wmgeneral.c), it
|
||
|
|
implements a subset of the interface using Gtk+ 2.0
