draw

Description:

public virtual signal bool draw (Context cr, int width, int height)

The draw signal is emitted each time a canvas is invalidated.

It is safe to connect multiple handlers to this signal: each handler invocation will be automatically protected by save and restore pairs.

cr	the Cairo context used to draw
width	the width of the `canvas`
height	the height of the `canvas`

true if the signal emission should stop, and false otherwise
