The HOpSelectPolygon class computes a selection list for objects inside a user-defined polygonal area.
HOpSelectPolygon employs all of the drawing functionality of HOpConstructPolyline to define a temporary, overlayed polygonal selection area, and then maps the polygon information to the HOOPS routine HC_Compute_Selection_By_Polygon. The operation consists of the following steps:
More Detailed Description: see event methods Functional Note: This operator does not provide exact results for HOOPS' Shell and Mesh primitives.
HOpSelectPolygon::HOpSelectPolygon | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpSelectPolygon 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. |

Creates a new operator which is a copy of the current operator. The user is responsible for deleting the newly created operator.

OnLButtonDblClk passes the polyline array from HOpConstructPolyline::OnLButtonDblClk into the HOOPS routine HC_Insert_Polygon and inserts the polygon into the scene. The polyline information is also passed to Compute_Selection_By_Polygon. Currently selected items are highlighted, and items previously highlighted are de-selected.
hevent | An HEventInfo object containing information about the current event. |

OnLButtonDown initiates the polygon selection mechanism.
