column selector for v.distance in wxGUI doesn't work

[cmbarton]

The column selector drop down for v.distance in the GUI dialog does not work. The same problem happens on a couple other modules, probably for the same reason.

Replying to cmbarton:

The column selector drop down for v.distance in the GUI dialog does not work. The same problem happens on a couple other modules, probably for the same reason.

The reason is that the wxGUI does not know to which vector the column option belongs if a module operates with more than one input vector map, such as v.distance. That would require some information to be stored with a particular column option, to what vector and layer option it belongs. Similarly, the wxGUI does not know to which vector a layer or table option belongs.

That makes sense. But seems like there ought to be a way to fix this. Typing the column name is a workaround of course.

This probably requires changes to g.parser and this will not happen now, changing milestone.

As a temporary solution, I would suggest that combobox (drop down selector) can be changed to simple text input field. This could avoid confusion of the user.

This is a good solution for GRASS 6.

Can someone change the relevant C code for this?

This is fixed in all current GRASS 7 versions. I assume that no one will fix in legacy GRASS 6. Closing
