QRegion QwtPickerTracker::maskHint ( ) const

protectedvirtual

Calculate an approximation for the mask.

AlphaMask The hint is used to speed up the algorithm for calculating a mask from non transparent pixels
NoMask The hint is unused.

The default implementation returns an invalid region indicating no hint.

Reimplemented from QwtWidgetOverlay.
