Detailed Description

Manager interactor class.

Library: ilvmgr
Use this class to create an IlvPolygon object in a view controlled by a manager. The virtual member function handleEvent() monitors mouse events. To draw a polygon, the user:

Clicks the left mouse button to set the point.
Presses the space bar, the enter key or double-clicks to finish.

§ IlvMakePolygonInteractor()

IlvMakePolygonInteractor::IlvMakePolygonInteractor	(	IlvManager *	manager,
		IlvView *	view
	)

Initializes a new instance of the IlvMakePolygonInteractor class.

view	The manager view.

Member Function Documentation

§ doIt()

virtual void IlvMakePolygonInteractor::doIt	(	IlUInt	count,
		IlvPoint *	points
	)

virtual

Finalizes the interaction by creating an IlvPolygon object.

Creates an IlvPolygon in the manager from the array of points provided during the interaction.

Parameters

count	The number of points in the array.
points	The array of points, in the object coordinate system.

Reimplemented from IlvMakePolylineInteractor.

Reimplemented in IlvMakeOutlinePolygonInteractor.

§ drawGhost()

virtual void IlvMakePolygonInteractor::drawGhost ( )

virtual

Provides the visual feedback during interaction.

Draws a polygon in XOR mode.
