Detailed Description
The HOpCreateCircle class draws a circle.
HOpCreateCircle maps the event information to the HOOPS routine #HC_Insert_Circle_By_Radius. This provides the basic functionality for drawing a temporary, overlayed 2-D box outline in the view plane based on first and last pointer positions. Once the operation is finalized, a circle will be inserted into the model. The operation consists of the following steps:
- Left Button Down: Identifies the center point of the circle.
- Left Button Down and Drag: Rubberband circle to desired dimensions.
- Left Button Up: Circle finalized, the polyline primitive used to represent the circle is flushed from the scene and a new one is created in the model.
More Detailed Description: see event methods.
Constructor & Destructor Documentation

HOpCreateCircle::HOpCreateCircle | ( | HBaseView * | view, |
int | DoRepeat = 0 , |

int | DoCapture = 1 , |

bool | UseCenterMarker = true |
||
) |
Constructs an HOpCreateCircle 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. UseCenterMarker Pass true if you want HOOPS to draw a mark at the center.
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 HOpCreateCircle object.
Reimplemented from HOpConstructCircle.
◆ GetName()
|
virtual |
- Returns
- A pointer to a character string denoting the name of the operator, which is 'HOpConstructCircle'.
Reimplemented from HOpConstructCircle.
◆ OnLButtonUp()
|
virtual |
OnLButtonUp finalizes the size of the circle, cleans up the geometry draw under the construction key and inserts a circle into the current model using #HC_Insert_Circle_By_Radius.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HOpConstructCircle.
