Detailed Description

a vtkContextItem that draws a block (optional label).

This is a vtkContextItem that can be placed into a vtkContextScene. It draws a block of the given dimensions, and reacts to mouse events.

vtkBlockItem can also be used to render label in the scene. The label properties can be set using vtkTextProperty accessed via GetLabelProperties.
