Member Function Documentation

void CursorDrag::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.

Definition at line 3325 of file editor_drag.cc.

bool CursorDrag::allow_vertical_autoscroll ( ) const

inlinevirtual

Reimplemented from Drag.

Definition at line 717 of file editor_drag.h.

void CursorDrag::fake_locate ( framepos_t t )

private

Do all the things we do when dragging the playhead to make it look as though we have located, without actually doing the locate (because that would cause the diskstream buffers to be refilled, which is too slow).

Definition at line 3225 of file editor_drag.cc.

void CursorDrag::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.

Definition at line 3304 of file editor_drag.cc.

void CursorDrag::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.

Definition at line 3295 of file editor_drag.cc.

void CursorDrag::start_grab	(	GdkEvent *	e,
		Gdk::Cursor *	c = `0`
	)

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 3247 of file editor_drag.cc.

bool CursorDrag::y_movement_matters ( ) const

inlinevirtual

Returns: true if y movement matters to this drag

Reimplemented from Drag.

Definition at line 721 of file editor_drag.h.
