	)

Definition at line 4345 of file editor_drag.cc.

void RubberbandSelectDrag::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 4380 of file editor_drag.cc.

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

virtual

		bool	drag_in_progress
	)

pure virtual

Select some things within a rectangle.

Parameters

button_state	The button state from the GdkEvent.
x1	The left-hand side of the rectangle in session frames.
x2	The right-hand side of the rectangle in session frames.
y1	The top of the rectangle in trackview coordinates.
y2	The bottom of the rectangle in trackview coordinates.
drag_in_progress	true if the drag is currently happening.

Implemented in MidiVerticalSelectDrag, MidiRubberbandSelectDrag, and EditorRubberbandSelectDrag.

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

virtual
