Member Function Documentation

◆ aborted()

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.

◆ finished()

void AutomationRangeDrag::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.

◆ motion()

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.

◆ setup()

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

private

◆ start_grab()

void AutomationRangeDrag::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.

◆ value()

double AutomationRangeDrag::value	(	std::shared_ptr< ARDOUR::AutomationList >	list,
