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

It seems like lots of beginning users and even some more experienced users have trouble dealing with issues arising in setting and changing region information. I'm wondering if there is someplace more information could be displayed automatically in the gui or somewhere else. I don't have a clear idea of what I'm suggesting but I'm going to be spending some quality time with the gui in the next few days and see if I can make more concrete suggestions.

I am working with version 6.3 from the cvs. Does gis.m get me the latest work by Michael, et. al or do I need to download something from a branch?

Thanks, Jerry

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. :wink:

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

the bottom of the GUI Map Display window gives you rows= cols= and res=
values, but not exact region bounds. (lack of space.. any suggestions
where to put that? expanding [+] list on that rows= cols= res= line?)

It gives you the latest of the mainstrem Tcl GUI, but not the
experimental next-gen wxPython GUI. for that see here:
