Constructor & Destructor Documentation

KisUpdateSelectionJob()

KisUpdateSelectionJob::KisUpdateSelectionJob	(	KisSelectionSP	selection,
		const QRect &	updateRect = QRect() )

TODO: we should implement correct KisShapeSelectionCanvas for projection. See a comment in KisUpdateSelectionJob::run().

Right now, since this job accesses some projections for write, we should declare it as exclusive

Definition at line 12 of file kis_update_selection_job.cpp.

run()

void KisUpdateSelectionJob::run ( )

TODO: in the future we should remove selection projection calculation from this job and to reuse a fully-featured shape layer canvas from KisShapeLayer. Then projection calculation will be a little bit more efficient.
