Member Function Documentation

◆ aborted()

virtual void RegionMotionDrag::aborted ( bool m )

virtual

Called to abort a drag and return things to how they were before it started.

Parameters

m	true if some movement occurred, otherwise false.

Implements Drag.

Reimplemented in RegionInsertDrag, and RegionMoveDrag.

◆ collect_ripple_views()

void RegionMotionDrag::collect_ripple_views ( )

protected

◆ compute_x_delta()

double RegionMotionDrag::compute_x_delta	(	GdkEvent const *	,
		Temporal::timepos_t &
	)

protected

◆ finished()

virtual void RegionMotionDrag::finished	(	GdkEvent *	e,
		bool	m
	)

virtual

Called when a drag has finished.

Parameters

e	Event describing the finish.
m	true if some movement occurred, otherwise false.

Implements Drag.

Reimplemented in RegionInsertDrag, and RegionMoveDrag.

◆ motion()

virtual void RegionMotionDrag::motion	(	GdkEvent *	e,
		bool	f
	)

virtual

Called when a drag motion has occurred.

Parameters

e	Event describing the motion.
f	true if this is the first movement, otherwise false.

Implements Drag.

Reimplemented in RegionMoveDrag.

◆ regions_came_from_canvas()

virtual bool RegionMotionDrag::regions_came_from_canvas ( ) const

pure virtual

Returns: true if the regions being ‘moved’ came from somewhere on the canvas; false if they came from outside (e.g. from the region list).

Implemented in RegionInsertDrag, and RegionMoveDrag.

◆ start_grab()

virtual void RegionMotionDrag::start_grab	(	GdkEvent *	e,
		Gdk::Cursor *	c
	)

virtual

Called to start a grab of an item.

Parameters

e	Event that caused the grab to start.
c	Cursor to use, or 0.

Reimplemented from Drag.

◆ y_movement_allowed()

virtual bool RegionMotionDrag::y_movement_allowed	(	int	,
		double	,
		int	skip_invisible = `0`
	)		const
