WinGRASS: 3D view wxNVIZ does not work

[hamish]

(moved here from osgeo4w bug # 37 ​http://trac.osgeo.org/osgeo4w/ticket/37 because it is seen both in the OSGeo4W and stand-alone installers)

• wx-nviz (no error message, when you switch the monitor to 3D view, nothing happens). Cog and O/I icons come up and overlap the eyeball and full-rerender icons in top left of the view window toolbar. starting with a blank map display a "Please wait, loading data..." grey box comes up in the map display. but nothing.

Nviz extension is checked in r37040. If not available, it's not shown in the toolbar.

is it possible to grey them (vdigit & wxnivz) out in the list instead of removing them? if not, having them pop up an explaination box? that way people don't pull their hair out trying to find them somewhere else because they remember they had seem them somewhere before..

thanks, Hamish

yes, it would be better, anyway wxPython doesn't allow disabling items in wx.Combobox (toolbar). It would be possible via customized widgets - extra work...

Another approach:

• don't remove items from toolbar's combobox
• after choosing e.g. 'vdigit', show dialog which explains to the user that the extension is not available.
• switch back to '2D view'

Would this be better from user point of view?

Yes; they learn where to find it in future, and can immediately stop hunting for it in the menus.
