#632: Thematic Maps

Hi everyone, I have noticed what seems to me to be a bug with displaying
thematic map layers in Grass 6.4 RC4 using Ubuntu 8.10.

When a thematic layer is displayed based on the attributes of a point
file, the initial thematic map display seems fine (i.e. the graduated
point symbols correspond with the locations of the point data in x,y
space). However, if I zoom in or out of the data or pan to a different
region, the thematic map layer does not zoom or pan with the the vector
layers or raster layers also being displayed, the graduated symbols seem
fixed to the display not associated with the point file that was used to
create it.

wxpython,

My apologies for failing to mention that earlier.

Comment (by yytsui):

I spent sometime to look into this issue and consider using FloatCanvas
http://trac.paulmcnett.com/floatcanvas/wiki to fixed this bug. However, If
we use FloatCanvas to display maps, that means probably a lot of codes in
gui/wxpython/gui_modules/mapdisp.py, mapdisp_windows.py ,wxgui_utils and
render.py has to be change. Anyone know how much effort this might cause?
And I just sent an email to FloatCanvas mailing list to ask whether does
FloatCanavas support multilayer.
Any suggestion?
Thanks

probably quite a lot of work. If you start I would suggest to make a fork
of wxGUI in grass-addons and later to merge it into trunk.
