The HOpConstructPolyline class draws a polyline.
HOpConstructPolyline implements three of the mouse button event handlers defined on the base class and maps the event information to create a polyline. This provides the basic functionality for dynamically creating a temporary, overlayed polyline in the view plane based on pointer input. The polyline points are stored in a protected member array until a double click event is passe. The operation consists of the following steps:

HOpConstructPolyline::HOpConstructPolyline | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpConstructPolyline 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* HOpConstructPolyline::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 HBaseOperator.
Reimplemented in HOpConstructNurbsCurve, HOpCreatePolyline, HOpSelectPolygon, HOpSelectPolyline, HOpSelectPolygonOOC< SelectionSet >, and HOpCreateNurbsCurve.
virtual const char* HOpConstructPolyline::GetName | ( | ) | [virtual] |
Reimplemented from HBaseOperator.
Reimplemented in HOpCreatePolyline, HOpConstructNurbsCurve, HOpCreateNurbsCurve, HOpSelectPolygon, HOpSelectPolyline, and HOpSelectPolygonOOC< SelectionSet >.
virtual int HOpConstructPolyline::OnLButtonDblClk | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDblClk places the final mouse position into the temp array. This function also takes care of any cleanup.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpConstructNurbsCurve, HOpSelectPolygonOOC< SelectionSet >, HOpCreatePolyline, HOpSelectPolygon, HOpSelectPolyline, and HOpCreateNurbsCurve.
virtual int HOpConstructPolyline::OnLButtonDown | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDown records the first mouse position and initiates the polyline-drawing mechanism. The function also records each successive point in the polyline in a temp array, and connects the points with a line.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpConstructNurbsCurve, HOpSelectPolygon, and HOpSelectPolygonOOC< SelectionSet >.
virtual int HOpConstructPolyline::OnNoButtonDownAndMove | ( | HEventInfo & | hevent | ) | [virtual] |
OnNoButtonDownAndMove draws a rubberbanded line from the previous point in the polyline to the current mouse position.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpConstructNurbsCurve.
int HOpConstructPolyline::m_PolylineCount [protected] |
The number of points in the polyline.
The key for HOOPS polyline.
HPoint* HOpConstructPolyline::m_pPolyline [protected] |
A pointer to the array of points for HOOPS Polyline in World Space.
HPoint HOpConstructPolyline::m_ptLast [protected] |
the last point in the temporary polyline array (not m_pPolyline) behind the current mouse position. See OnLButtonDown.
