Member Function Documentation

void AutomationRangeDrag::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.

Parameters

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

Implements Drag.

Definition at line 5501 of file editor_drag.cc.

void AutomationRangeDrag::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 5485 of file editor_drag.cc.

void AutomationRangeDrag::setup ( std::list< boost::shared_ptr< AutomationLine > > const & lines )

private

Parameters

lines	AutomationLines to drag.
offset	Offset from the session start to the points in the AutomationLines.

Definition at line 5319 of file editor_drag.cc.

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