Detailed Description

The basis of all event processing in Core Plot.

Method Documentation

pointingDeviceCancelledEvent:

- (BOOL) pointingDeviceCancelledEvent:

(nonnull CPTNativeEvent *)

event

(Required) Informs the receiver that tracking of mouse moves has been cancelled for any reason.

Parameters

event

The OS event.

Returns

Whether the event was handled or not.

Reimplemented in CPTGraph, CPTPlotSpace, CPTAnnotationHostLayer, and CPTPlotAreaFrame.

pointingDeviceDownEvent:atPoint:

- (BOOL) pointingDeviceDownEvent:		(nonnull CPTNativeEvent *)	event
atPoint:		(CGPoint)	interactionPoint

(Required) Informs the receiver that the user has pressed the mouse button.

Parameters

event	The OS event.
interactionPoint	The coordinates of the interaction.

Returns

Whether the event was handled or not.

Reimplemented in CPTPieChart, CPTPlot, CPTTradingRangePlot, CPTRangePlot, CPTBarPlot, CPTScatterPlot, CPTGraph, CPTLegend, CPTPlotArea, CPTPlotSpace, CPTAnnotationHostLayer, CPTAxis, CPTAxisSet, CPTPlotAreaFrame, and CPTXYPlotSpace.

pointingDeviceDraggedEvent:atPoint:

- (BOOL) pointingDeviceDraggedEvent:		(nonnull CPTNativeEvent *)	event
atPoint:		(CGPoint)	interactionPoint

(Required) Informs the receiver that the user has moved the mouse with the button pressed.

Parameters

event	The OS event.
interactionPoint	The coordinates of the interaction.

Returns

Whether the event was handled or not.

Reimplemented in CPTGraph, CPTPlotSpace, CPTAnnotationHostLayer, CPTPlotAreaFrame, and CPTXYPlotSpace.

pointingDeviceUpEvent:atPoint:

- (BOOL) pointingDeviceUpEvent:		(nonnull CPTNativeEvent *)	event
atPoint:		(CGPoint)	interactionPoint

(Required) Informs the receiver that the user has released the mouse button.

Parameters

event	The OS event.
interactionPoint	The coordinates of the interaction.

Returns

scrollWheelEvent:fromPoint:toPoint:

- (BOOL) scrollWheelEvent:		(nonnull CPTNativeEvent *)	event
fromPoint:		(CGPoint)	fromPoint
toPoint:		(CGPoint)	toPoint

(Required) Informs the receiver that the user has moved the scroll wheel.

Parameters

event	The OS event.
fromPoint	The starting coordinates of the interaction.
toPoint	The ending coordinates of the interaction.

Returns

Whether the event was handled or not.

Reimplemented in CPTGraph, CPTPlotSpace, and CPTXYPlotSpace.
