Constructor

new HitTestManager(canvas): HitTestManager;

Parameters

Parameter	Type
canvas	Canvas

Returns

HitTestManager

Methods

findItemByHitTest()

findItemByHitTest(point, coordinateSystem?): Item;

Returns item from current container that contains specified point. If more than one item matches the point, then this method returns first selected item, if any. If there is no selected item, this method returns first item by the z order.

Parameters

Parameter	Type	Default value	Description
point	PointF	undefined	the point.
coordinateSystem	CoordinateSystem	CoordinateSystem.page	the coordinate system in which point is defined. If value of the coordinateSystem is not provided then page is used as coordinateSystem.

Returns

Item

Item.

getFirstHandlerByHitTest()

getFirstHandlerByHitTest(workspacePoint): BaseRectangleItemHandler;

Parameters

Parameter	Type
workspacePoint	PointF

Returns

BaseRectangleItemHandler

getItemHandlersByHitTest()

getItemHandlersByHitTest(point, coordinateSystem?): BaseRectangleItemHandler[];

Returns all item handlers from current container that can be selected and that contain specified point.

Parameters

Parameter	Type	Default value	Description
point	PointF	undefined	the point.
coordinateSystem	CoordinateSystem	CoordinateSystem.page	the coordinate system in which point is defined. If value of the coordinateSystem is not provided then page is used as coordinateSystem.

Returns

BaseRectangleItemHandler[]

array of ItemHandlers.
