Inherits From:

TCanvasDragInteractor

Inherited By:

None.

Purpose:

Interactor that rotates canvas graphics in a specified selection.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

Intended to be used as is but can also be derived.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Member Function: TCanvasGraphicRotatingInteractor::TCanvasGraphicRotatingInteractor

TCanvasGraphicRotatingInteractor (MCanvasSelection * adoptTarget, MToolHandler *, const TGPoint & centerOfRotate)

Interface Category:

API.

Purpose:

Constructor.

Calling Context:

Intended to be called by a TSRTFeedbacker or derived class.

Parameters:

MCanvasSelection * adoptTarget -The selection that specifies the graphics to be scaled.
MToolHandler * -The application's tool handler.
const TGPoint & centerOfRotate -The transformed center of rotation.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

If the center of rotation is the center of the SRT Feedbacker, then centerOfRotate should be the center of the point returned from the SRT feedbacker's HandleGetBounds member function, transformed by the SRT feedbacker's transform. The SRT feedbacker's transform can be obtained by calling MCanvasGraphic::GetTransform for the feedbacker.
