The child interactors of this interactor. This property may be null.

Controls the dragging behavior of the interactor.

The height of the interactor. Subclasses should override this method so that it correctlty reflects the height of the interactor.

The cursor that will be used when the mouse hovers over the interactor. By default, the parent cursor is used.

Controls whether an interactor can be interacted with.

The layers of this interactor.

The layout property controls the placement of sub-interactors relative to this one. This property may be null.

The controlled object.

A value between 0 and 1 that specifies the opacity of the interactor. 1 means fully opaque, 0 means fully transparent (i.e. invisible). The default is 1.

The interactor that this interactor is a child of.

The rectangle that this interactor occupies, including the space taken by its layers.

The distance at which the shadow of the interactor will be drawn. This distance is relative to the parent, so that transformations on this interactor (such as rotations) do not influence the location of the shadow.

The tooltip for this interactor. Override this to return the proper information for this interactor. If null, no tooltip will be shown.

Transformation that is applied to the interactor before drawing, relative to the origin of its parent, i.e.:

• If one applies this transformation to a local coordinate, one obtains the coordinates in the coordinate system of the parent.
• If one uses this transformation to transform the parent coordinate system (CTM), one obtains the local coordinate system.

The viewer that this interactor is located in.

Transforms coordinates in the local coordinate system to the coordinate system of the viewer, i.e.:

• If one applies this transformation to a local coordinate, one obtains the coordinates in the coordinate system of the viewer.
• If one uses this transformation to transform the original viewer coordinate system (CTM), one obtains the local coordinate system.

A rectangle that defines a the visible part of the interactor, in terms of its own coordinate system.

The width of the interactor. Subclasses should override this method so that it correctlty reflects the width of interactor.
