Changes from Verson 2.3 to 3.0 by Anthony Thyssen
* Complete rewrite of data structures and routines for reading and
displaying the icons from a directory.
* Addition of X Pixmaps and color
* File type enumeration (Bad, Dir, File (unknown), Xbm, Xpm, BadXpm...)
* Minor changes to get_files() in misc.c for determining file type
and recording the last modified time.
* Change to method used to display icon details when pointer inside
a displayed icon. Avoid scanning the data structure for the icons name
by setting the name into the widget used.
Their should be a way of attaching a general pointer to any widget.
You would think that givening a structure pointer instead of a string
for a widgets label would work but it doesn't. XtSetValues it seems
makes a new copy of any string passed to it for use by the widget.
* Made two global strings for information labels for information on the
number of bitmaps, pixmaps, unknown files and directories present in
the current directory to be displayed. Very handy.
* Removed the Scan directory completely method for a rescan changes
method. This method is equivelent to the original if the old file_list
is destroyed before it is called.
Future updates.
* Current directory text widget, move cursour to end and append '/'
automatically, to allow easier modification by the user.
* A count on the color allocations the pixmaps use so colors no longer
being displayed can be freed for reuse by other icons. This would be
especially important when changing directories. Currently if you
change directories of pixmaps with large color use (IE full pictures
instead of icons!), few of the new icons will be displayable due to
color allocation problems.
* Seperate user menus for pixmaps and bitmaps?
