Detailed Description
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:
- Left Button Down: Registers the center point of the circle.
- Left Button Down and Drag: Creates a circle of appropriate radius in the contruction layer.
- Left Button Up: Depending on existence of an active markup layer it either opens the existing or creates a new markup layer and inserts appropraitely sized circle into it.
More Detailed Description: see event methods.
Constructor & Destructor Documentation
◆ HOpMarkupCircle()
HOpMarkupCircle::HOpMarkupCircle | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpMarkupCircle 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 HOpMarkupCircle object.
Reimplemented from HOpConstructCircle.
◆ GetName()
|
virtual |
- Returns
- A pointer to a character string denoting the name of the operator, which is 'HOpMarkupCircle'.
Reimplemented from HOpConstructCircle.
◆ OnLButtonUp()
|
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.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HOpConstructCircle.
