◆ unsetCanvas()

void SmallColorSelectorDock::unsetCanvas ( )

inlineoverridevirtual

Re-implement to notify the observer that its canvas is no longer among the living. The daisies, it is pushing up. This means you don't have to disconnect, it's dead.

The old canvas should be deleted already, so if you stored a pointer to it, don't touch!

Note that currently there is a bug where in certain specific circumstances unsetCanvas can be called when it shouldn't, see for example KWStatisticsDocker for a workaround for this problem.

Implements KoCanvasObserverBase.
