Manager interactor class.
Library: ilvmgr
Use this class to create IlvFilledSpline
objects in a view controlled by a manager. The virtual member function handleEvent
monitors mouse events. To draw a filled spline, the user:
Presses the return or space key, or double clicks to finish.
If the user presses the Control modifier while dragging the left mouse button, the left and right tangents at the current point are dissociated, letting the user create cusps on the Bezier spline.
IlvMakeFilledSplineInteractor::IlvMakeFilledSplineInteractor | ( | IlvManager * | manager, |
IlvView * | view | ||
) |
Constructor.
Initializes a new instance of the IlvMakeFilledSplineInteractor
class.
manager | The manager. |
view | The manager view. |
|
virtual |
Called by handleEvent
when the polypoint is terminated. This method should call doIt() and post an undoable command if need be.
removeExtraPoints | When the curve entry is terminated by a double click, it may be desirable to remove the extra points that have been added in succession by the double click. This flag is set to tell the method that it should get rid of the extraneous points before calling doIt() . |
Reimplemented from IlvMakeSplineInteractor.
Finalizes the interaction by creating an IlvFilledSpline
object.
Creates an IlvFilledSpline
in the manager from the array of points provided during the interaction.
count | The number of points in the array. |
points | The array of points, in the object coordinate system. |
Reimplemented from IlvMakeSplineInteractor.
Reimplemented in IlvMakeClosedSplineInteractor.
|
virtual |
Visual feedback during interaction.
Draws a filled spline in XOR
mode.
Reimplemented from IlvMakeSplineInteractor.
Reimplemented in IlvMakeClosedSplineInteractor.
Ensures the Bezier spline stays continuously derivable as new points are entered.
When a new control point is added, the default implementation realigns the previous control points if needed, to ensure that the Bezier remains continuous at each control point, including the start and end points.
Reimplemented from IlvMakeSplineInteractor.
