Detailed Description
The HOpCreatePolyline class draws a polyline.
HOpCreatePolyline maps event information to the HOOPS routine HC_Insert_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 passed, then the array is inserted into the HOOPS database. The operation consists of the following steps:
- Left Button Down: The operation is initiated and the first point of the polyline is recorded.
- No Button Down and Drag: Rubberband line segment to the desired position of the next point.
- Left Button Down: The next point in polyline is recorded and continues until the user double clicks the left mouse button.
- Left Button Double Click: The polyline is finalized and the polyline primitive is flushed from the scene and a new one is inserted into the model.
More Detailed Description: see event methods.
Constructor & Destructor Documentation
◆ HOpCreatePolyline()
HOpCreatePolyline::HOpCreatePolyline | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpCreatePolyline object.
- Parameters
-
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.
Member Function Documentation
◆ Clone()
|
virtual |
Creates a new operator which is a copy of the current operator. The user is responsible for deleting the newly created operator.
- Returns
- A pointer to the newly created HOpCreatePolyline object.
Reimplemented from HOpConstructPolyline.
◆ GetName()
|
virtual |
- Returns
- A pointer to a character string denoting the name of the operator, which is 'HOpCreatePolyline'.
Reimplemented from HOpConstructPolyline.
◆ OnLButtonDblClk()
|
virtual |
OnLButtonDblClk places the final mouse position into the temp array, then inserts the array into the database as a HOOPS polyline. This function also takes care of any cleanup.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HOpConstructPolyline.
