[GRASS-dev] NVIZ now broken?

[Michael Barton]

Paul,

Thanks much for the update. This  is easy to fix in nviz. The widget label
can be provided by a separate label widget instead of using the ComboBox
-label option. 

However, I'm much more concerned about the larger issue of the version of
bwidgets that GRASS depends on not working correctly. This same ComboBox
widget with -label option is used in a number of other places in the GUI
(such as the GIS Manager vector layer panel).

If it is failing in one place (nviz) it should be failing in all places if
this is a general problem. If it is only failing in nviz, there is some
other more fundamental problem that needs to be solved or I will have no
idea of what kinds of GUI options work and which do not.

I just tried the new nviz GUI updates on our FC4 system. I still have to
find out which version of TclTk it is running, but nviz works
fine--including the ComboBox with -label option. Given Paul's message, it
doesn't sound like it is limited to a particular version of TclTk or OS. So
something else is broken.

Michael
