Detailed Description

QgsMapToolCapture is a base class capable of capturing point, lines and polygons.

The tool supports different techniques: straight segments, curves, streaming and shapes Once the the geometry is captured the virtual private handler geometryCaptured is called as well as a more specific handler (pointCaptured, lineCaptured or polygonCaptured)
