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 RegionRippleDrag, RegionSpliceDrag, RegionInsertDrag, and RegionMoveDrag.

Definition at line 1780 of file editor_drag.cc.

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 RegionRippleDrag, RegionSpliceDrag, RegionInsertDrag, and RegionMoveDrag.

Definition at line 1276 of file editor_drag.cc.

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 RegionRippleDrag, RegionSpliceDrag, and RegionMoveDrag.

Definition at line 745 of file editor_drag.cc.

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.

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.

Definition at line 567 of file editor_drag.cc.
