The HOpCreateNurbsCurve class provides support for constructing a Non Uniform Rational B-Spline (NURBS) curve and inserting it into the model.
HOpCreateNurbsCurve uses event information to draw a NURBS curve. The class employs all of the drawing functionality of HOpConstructPolyline to draw a temporary, overlayed NURBS curve and associated 'control polyline' in the view plane, and then uses the HOOPS routine HC_Insert_NURBS_Curve to add a curve to the model.
The operation consists of the following steps:

HOpCreateNurbsCurve::HOpCreateNurbsCurve | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpCreateNurbsCurve object.
view | A pointer to an HBaseView object. |
DoRepeat | An integer denoting whether this is a repeatable operator. This parameter has been deprecated. |
DoCapture | An integer denoting whether the mouse state should be captured, which means that all mouse events should be received after a mousedown, even if it leaves the window. This parameter has been deprecated. |
virtual HBaseOperator* HOpCreateNurbsCurve::Clone | ( | ) | [virtual] |
Creates a new operator which is a copy of the current operator. The user is responsible for deleting the newly created operator.
Reimplemented from HOpConstructNurbsCurve.
virtual const char* HOpCreateNurbsCurve::GetName | ( | ) | [virtual] |
Reimplemented from HOpConstructNurbsCurve.
virtual int HOpCreateNurbsCurve::OnLButtonDblClk | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDblClk directs the final mouse position into the temp array, then inserts the array into the database as a NURBS curve. This function also takes care of any cleanup.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HOpConstructNurbsCurve.
