		RouteTimeAxisView *	dest_rtv,
		ARDOUR::layer_t	dest_layer,
		ARDOUR::framecnt_t	where,
		PlaylistSet &	modified_playlists
	)

private

Insert a region into a playlist, handling the recovery of the resulting new RegionView, and clearing the playlist's diff history first if necessary.

Parameters

region	Region to insert.
dest_rtv	Destination RouteTimeAxisView.
dest_layer	Destination layer.
where	Destination position.
modified_playlists	The playlist will be added to this if it is not there already; used to ensure that clear_changes () is only called once per playlist.

Returns: New RegionView, or 0 if no insert was performed.

void RegionMoveDrag::motion	(	GdkEvent *	e,
		bool	f
	)

virtual

Called when a drag motion has occurred.

Parameters

Reimplemented from Drag.

Definition at line 364 of file editor_drag.h.

bool RegionMoveDrag::regions_came_from_canvas ( ) const

inlinevirtual

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).

Implements RegionMotionDrag.

private

Remove a region from a playlist, clearing the diff history of the playlist first if necessary.

Parameters

region	Region to remove.
playlist	playlist To remove from.
modified_playlists	The playlist will be added to this if it is not there already; used to ensure that clear_changes () is only called once per playlist.

Definition at line 1677 of file editor_drag.cc.

void RegionMoveDrag::setup_pointer_frame_offset ( )

virtual

Set up the _pointer_frame_offset
