The HOpMarkupCircle class inserts a 2D circle into a markup layer. If a layer is already active, then the operator will use that layer. Otherwise, the operator will create a new unnamed layer.
HOpMarkupCircle implements three mouse event methods defined on the base class and maps the event information to operator routines. This operation consists of the following steps:
More Detailed Description: see event methods.
HOpMarkupCircle::HOpMarkupCircle | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpMarkupCircle 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* HOpMarkupCircle::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 HOpConstructCircle.
virtual const char* HOpMarkupCircle::GetName | ( | ) | [virtual] |
Reimplemented from HOpConstructCircle.
virtual int HOpMarkupCircle::OnLButtonUp | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonUp maps circle information from HOpConstructCircle into the HOOPS routine HC_Compute_Selection_By_Area. This function also deselects any selected items that are not present in the current selection list.
hevent | An HEventInfo object containing information about the current event. |
