The HOpSelectArea class computes a selection list for objects inside a rectangular area.
HOpSelectArea employs all of the drawing functionality of HOpConstructRectangle to define a temporary, overlayed rectangular selection area, then maps the rectangle information to the HOOPS routine HC_Compute_Selection_By_Area. This class provides the basic functionality for window selection. The operation consists of the following steps:

int | DoCapture = 1 |

) |
Constructs an HOpSelectArea 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 associated with the same view as the current operator. The user is responsible for deleting the newly created operator.

This method calls through to HOpConstructRectangle's OnLButtonDown method to record the first point and initiates the rectangle drawing mechanism. Then it sets attribute values for color and visibility that are specific to the selection by area.
hevent | An HEventInfo object containing information about the current event. |

This method maps rectangle information from HOpConstructRectangle into the HOOPS routine HC_Compute_Selection_By_Area to update the selection set in the associated view. It also deselects any selection items that are not present in the current selection list.
