wxgui / osgeo4w: db.describe execution failed

[hamish]

Hi,

latest OSGeo4W binary install of 6.4.0rc3 on windows xp.

using the wxpython GUI.

Spearfish: add vector map

select roads. (or any other map) don't even press [ok].

pop up error:

window title: Error in command execution db.describe.exe

Execution failed 'db.describe.exe -c --q table=roads driver=dbf database=C:/DocumentsandSettings/Hamish/grassdata/spearfish60/PERMANENT/dbf/'

Details:
Error: Unable to open database <C:/DocumentsandSettings/Hamish/grassdata/spearfish60/PERMANENT/dbf/>

perhaps it is something to do with the spaces being stripped out of "DocumentsandSettings" ??

after that the map renders ok, but I get the same error if I try to query the vector map.

querying the elevation.10m raster map spits out some error messages to the output window but then scrolls away and gives good data. (sorry already gone, no cut&paste)

Hopefully fixed in r35990. Martin

Hi,

attempting to try out these changes by copying in wxgui.py, gis_set.py, and the gui_modules/ dir from SVN over the top of the OSGeo4W 6.4.0rc3 files on the Windows machine. When I try to start GRASS I get this error:

Do you mean to copy from trunk/devbr6? If so, don't copy, but merge the changes - wxGUI changed a lot since relbr64, 'grassenv' has been removed from trunk and devbr6.

Copying files from relbr64 should work.

ok, I tried again with full dir, seemed to start up ok this time.

adding vector maps works without error, as does querying vector and raster maps.

I notice trying to Query vector map (edit mode) for roads@PERMANENT [spearfish] gives me a pop up window error about not being able to find the DBF file, and if I try again I get a traceback error in the Command Output window. It should error-out if the map in not in the current mapset (perhaps at the module level?) as @othermapset should always be read-only.

strangely the rendered map in the map display canvas became smaller while I was doing these tests (first just a sliver on the right, then when I hit the eyeball redraw button about 1/2 the canvas width). [Render [] is ticked] Zoom to selected map didn't help, needed to fully use the zoom _(+) tool. aaaaaaaaah, the surviving part of the map display is that which IS overlapped by the Layer Manager window when I change the "Comand output" tab to "map layers for display" then put the Map display window back on top. very weird. "Re-render map" doesn't help, but the pan tool does. Again: clicking the eyeball makes the unoverlapped part disappear. now it works. strange, maybe change of map (roads(vect)/elevation.10m) is part of it. ?? hmmph, oh well. something to keep an eye out for.

in r36092 is added check for vector map mapset, in the result it's possible to query in this mode only vector maps from the current mapset.
