#2928: query tool does not work in wx display
------------------------+-------------------------
 Reporter:  veroandreo  |      Owner:  grass-dev@…
     Type:  defect      |     Status:  new
 Priority:  normal      |  Milestone:  7.1.0
Component:  wxGUI       |    Version:  svn-trunk
 Keywords:  query tool  |        CPU:  x86-64
 Platform:  Linux       |
------------------------+-------------------------
 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:

 {{{

 }}}

 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

 }}}
