[GRASS-dev] [SoC Report #1] Kriging with GRASS and R: v.autokrige port to wxPython and more

[Michael Barton]

Anne,

There is a good book to get you started with wxPython by the author  
Robin Robin Dunn ("wxPython in Action"). Also there is a very good  
wxPython doc application that comes with the distribution. It is  
generic for wxWindows and wxPython, but they are quite close. For  
special wxPython features, download the wxPython "new docs" from the  
wxPython site and access them via your browser.

Michael
