[GRASS-dev] displaying more info automatically in the gui

[Michael Barton]

Jerry,

Thanks for taking the time to look at the interface and offer suggestions.
For improved information, maybe you could be the one to enhance this in
places.  ;-)

Region setting is both complicated and simple, a real help and a pain. The
important thing to remember about the GUI is that the display is no longer
automatically connected to setting the computational region (i.e., the
region used by grass commands for bounding the extents to which they operate
and the resolution (for rasters) at which they operate. There are many good
reasons for this. An important one is that it allows multiple displays to
offer different views of a region without changing the computational region
in unexpected ways.

There are, however, easy ways to set the computational region from the
display and the display from the computational region explicitly.

The TclTk GUI is the current one with GRASS (started automatically or with a
script named "gis.m" (for gis manager as successor to "d.m" display
manager). 

However, I'm trying not to add *new* features to this (but am still actively
maintaining it and working to improve its robusticity) in order to have time
to work on the new GUI under development in wxPython. The new development
GUI can be downloaded and installed from the GRASS Addons SVN server. It
requires that you install Python 2.4 or greater and wxPython 2.8.x
