TkGoodStuff Images
Using Icons in TkGoodStuff
The standard buttons (as used by Biff and Net, and as produced by
AddButton) may contain icons and/or text. Icons are read in from
files. To specify an icon, you give the file name:
/usr/include/X11/bitmaps/datebook
$images/warning
(Remember that $images names the images subdirectory of the
tkgoodstuff library.)
What sorts of images can tkgoodstuff handle? This depends on the wish
executable you choose when installing tkgoodstuff. The standard tk4.0
distribution comes with wish4.0; so this is the wish executable
that is looked for as a default. If you use this default, then you
can use images that are bitmaps, ppm's, and gif's. More image formats
likely will become "standard" in the future.
If you are eager to use another image format (e.g., xpm's), you will
need to get a wish executable that is extended so as to understand
images of that format. For instance, the source for one such
interpreter, which I call "xpmwish4.0" is in
ftp://merv.philosophy.lsa.umich.edu/pub/ (I didn't write this
code; the credits are included). Also, Tix4.0's tixwish
understands xpm. But for this application, I recommend using the
smaller, simpler xpmwish4.0.
