[GRASS-dev] can't find : mapdisp_command.py

Hi All,

i'm trying to call a mapdisp canvas from a wxpython script to show a grass-mapdisplay and load a grass rastermap inside it.
My final target is to use the mouse action and capture the coordinates from the mapcanvas, where the user will release the mouse-sx-button.

In order to achieve this target from a wx script, i was looking in the georeferencer module, but trying to reuse its class : gcpmapdisp.py

i receive the error message :

no module named mapdisp_command

actually i checked in the grass7.0 source svn (rev.: 47601 ) but i can't find it.

please have you any hints/suggestion/example-code to achieve my target ?

thankYou very much!

--Massimo.

this python module has been recently removed, see newly added GRASS
module d.mon for wx-monitor usage.

Hi Martin,

thanks for the hints,

i tried :

d.mon start=wx0
d.rast map=mymap

adding this command in a grass wxpython extension module,
allow me to start a new map-dislpay and visualize a raster map on it.

how can i interact whit this new generated canvas ?
i tried to use “d.where” but seems to me that it is is not connected to the active/selected map-display.

thanks for any hints,

– Massimo.

use wxGUI map display functionality...

i tried to use "d.where" but seems to me that it is is not connected to the

d.mon is a quite new creature in G7, `d.where` is not connected to the
wx monitors.

so, after a sequence of

d.mon start=wx0
d.rast map=map

then is possible to use wx.GUI functionality (api?) to interact whi "wx0" ?
which class i need to import in the python module in order to capture the mouse on-click signal ?

in the wxgui code, where can i find the lines of code that refer to mouse mapcanvas picking ?
thanks for any usefull hints!
