query tool does not work in wx display

[veroandreo]

Query tool in grass71 (r67891) does not work with wx display (d.mon wx0), neither for raster maps, nor for vector maps. In both cases I get the following error:

Traceback (most recent call last):

In rel_branch (r67880) it does work both for raster and vector maps, but in console I get the following every time I click somewhere in the wx display

(main.py:31358): Gtk-CRITICAL **: gtk_widget_set_size_request: assertion 'height >= -1' failed

This is still not working in r68197. A pity because it's a quick way to check values at the same position in several raster maps.

Please try r68246 and test both d.mon and main GUI.

Thanks, Anna! Works fine now both using d.mon and the main map display in the GUI. However, in both cases, the first time I click over the displayed map, I still get this message in the terminal:

(main.py:9791): Gtk-CRITICAL **: gtk_widget_set_size_request: assertion 'height >= -1' failed

Thanks. The gtk error is unrelated and I think harmless.
