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

CHANGES:

|
|
15/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
|
||
|
|
* Updated createXBMfromXPM to handle the case where the XBM is to be
|
||
|
|
wider than the XPM, or the XBM width is not a multiple of 8.
|
||
|
|
* 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)
|
||
|
|
* Removed the rc-file and mouse region stuff to their own files.
|
||
|
|
* Renamed this file to "wmgeneral-x11.c"
|
||
|
|
* Renamed a few of the functions
|
||
|
|
|
||
|
|
28/08/2001 (Brad Jorsch, anomie@users.sourceforge.net)
|
||
|
|
* Added EnableMouseRegion and DisableMouseRegion
|
||
|
|
* Got annoyed with the 81-character lines. Fixed it. If you don't like
|
||
|
|
it, find a different copy of wmgeneral.c ;)
|
||
|
|
* GraphicsExpose events are enabled here.
|
||
|
|
* GetXPM is exported. It optionally takes an XpmColorSymbol array.
|
||
|
|
* GetColor is exported.
|
||
|
|
|
||
|
|
30/09/2000 (Brad Jorsch, anomie@users.sourceforge.net)
|
||
|
|
* You know, wmgen.mask sounds like a much nicer place to store the
|
||
|
|
mask... why don't we do that?
|
||
|
|
|
||
|
|
21/09/1999 (Brad Jorsch, anomie@users.sourceforge.net)
|
||
|
|
* Changed openXwindow to use only the filename, sans path,
|
||
|
|
as the name and class properties of the app.
|
||
|
|
|
||
|
|
14/09/1998 (Dave Clark, clarkd@skyia.com)
|
||
|
|
* Updated createXBMfromXPM routine
|
||
|
|
* Now supports >256 colors
|
||
|
|
11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|
||
|
|
* Removed a bug from parse_rcfile. You could
|
||
|
|
not use "start" in a command if a label was
|
||
|
|
also start.
|
||
|
|
* Changed the needed geometry string.
|
||
|
|
We don't use window size, and don't support
|
||
|
|
negative positions.
|
||
|
|
03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|
||
|
|
* Added parse_rcfile2
|
||
|
|
02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|
||
|
|
* Added -geometry support (untested)
|
||
|
|
28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|
||
|
|
* Added createXBMfromXPM routine
|
||
|
|
* Saves a lot of work with changing xpm's.
|
||
|
|
02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|
||
|
|
* changed the read_rc_file to parse_rcfile, as suggested by Marcelo E. Magallon
|
||
|
|
* debugged the parse_rc file.
|
||
|
|
30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|
||
|
|
* Ripped similar code from all the wm* programs,
|
||
|
|
and put them in a single file.
