Syntax

public abstract class HitTestObjectBase : IHitTestObject

The HitTestObjectBase type exposes the following members.

Constructors

	Name	Description
	HitTestObjectBase	Creates a new HitTestObject.

Properties

	Name	Description
	DoubleClick	Delegate to handle double click events. Should return true if the object was removed during the processing. Otherwise returns false.
	HittedObject	Gets or sets the object that corresponds to the selection path.
	ObjectOutlineForArrangements	Returns the object outline path in page coordinates used for arrangement of multiple objects together. Thus it should describes the object as accurate as possible. In case of lines shapes, it is the line path without widening. In case of closed shapes, it is the outline path of the shape.
	ParentLayer	Gets or sets the parent layer of the hit object.
	Remove	Handler to remove the hitted object. Should return true if the object is removed, otherwise false.
	Transformation	This will return the transformation matrix. This matrix translates from coordinates of the parent of the object (i.e. mostly the parent layer) to global coordinates.

Methods

	Name	Description
	ChangeSize	Changes the size of the hitted item either in x or in y direction.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetGrips	Shows the grips, i.e. the special areas for manipulation of the object.
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetNextGripLevel	Retrieves the next grip level.
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	OnDoubleClick	This handles the double-click event
	ShiftPosition	Shifts the position of the object by x and y. Used to arrange objects.
	ToString	Returns a string that represents the current object. (Inherited from Object)
	Transform	Appends a transformation to the transformation matrix of the hit test object. Call this while walking down the hierarchie of objects.

Fields

	Name	Description
	_hitobject	The hitted object.
	_matrix	Transformation matrix which transforms the coordinates of the parent of the hitted object (i.e. the parent layer) into page coordinates.
