Doug Torrance fa7743bc58 libdockapp: Do not include pathnames in Window Name and Class Properties 
Patch by Corin-EU from GitHub [1].

In libdockapps file wmgeneral.c, wname is set from argv[0] and is then used
to set the window name and class resource. Often applications are called with
their full path which then means that the window name has a path in it,
thereby requiring an unwieldy path specific string for "Name" in WMState if
the applet is to be captured in the WM dock.

The simple solution is that wname should be the basename of argv[0] to
ensure that the window name for the applet is the simple and obvious one.
Thus the inclusion of header file libgen.h is required.

Just say "no" to path slashes "/" in window name/class resources ....

Raw Blame History

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

CHANGES:
---
10/10/2003 (Simon Law, sfllaw@debian.org)
* changed the parse_rcfile function to use getline instead of
fgets.
10/14/2000 (Chris Gray, cgray@tribsoft.com)
* Removed a bug from parse_rcfile. An extra
newline would cause a segfault.
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.
