[Qgis-developer] Where can I find "add feature" code?

[Matthias Kuhn]

Hi Alexander,

You probably would want to create your own class which inherits 
QgsMapTool to receive the mouse events and manage the rubberband.

You'll find the code for the add feature tool in 
src/app/qgsmaptooladdfeature.{h|cpp} if you're looking for C++ code.

The attached link [1] points to a map tool I wrote (in python) which 
makes use of a line rubberband and some additional snapping stuff.

Regards,
Matthias
