The HOpConstructCircle class draws a circle.
HOpConstructCircle implements three of the mouse button event handlers and uses the event information to draw a circle. This class provides the basic functionality for drawing a temporary, overlayed 2-D box outline in the view plane based on first and last pointer positions. The operation consists of the following steps:

int | DoRepeat = 0 , |
||
int | DoCapture = 1 , |

bool | UseCenterMarker = true |
||
) |
Constructs an HOpConstructCircle 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. |
UseCenterMarker | Pass true if you want HOOPS to draw a mark at the center. |

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

OnLButtonDown records the first mouse position and initiates the circle-drawing mechanism.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
|
virtual |
OnLButtonDownAndMove draws rubberbanded lines along the circumference of the circle centered on the first pointer position. Note that the basic dynamic drawing work is done by repeated calls to the HUtility::CreateAxisCircle while OnLButtonDownandMove keeps track the changing radius value.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
|
virtual |
OnLButtonUp finalizes the size of the circle and cleans up the geometry that was drawn under the construction key.
hevent | An HEventInfo object containing information about the current event. |
