Detailed Description
The HOpConstructRectangle class draws a rectangle.
HOpConstructRectangle implements three of the mouse button event handlers and uses the event information to draw a rectangle. 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. The operation consists of the following steps:
- Left Button Down: Registers the first point of the rectangle.
- Left Button Down and Drag: Rubberbands the rectangle to the desired dimensions.
- Left Button Up: The rectangle finalized and the polyline primitive used to represent the rectangle is flushed from the scene.
More Detailed Description: see event methods.
Constructor & Destructor Documentation
◆ HOpConstructRectangle()
HOpConstructRectangle::HOpConstructRectangle | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 , |
||
bool | UseCenterMarker = true |
||
) |
Constructs an HOpConstructRectangle 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 render a mark at the center of the rectangle.
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 HOpConstructRectangle object.
Reimplemented from HBaseOperator.
Reimplemented in HOpCameraZoomBox, HOpSelectArea, HOpCreateRectangle, HOpSelectAreaOOC< SelectionSet >, and HOpMarkupRectangle.
◆ GetName()
|
virtual |
- Returns
- A pointer to a character string denoting the name of the operator, which is 'HOpConstructRectangle'.
Reimplemented from HBaseOperator.
Reimplemented in HOpCreateRectangle, HOpSelectArea, HOpCameraZoomBox, HOpSelectAreaOOC< SelectionSet >, and HOpMarkupRectangle.
◆ OnLButtonDown()
|
virtual |
OnLButtonDown records the first mouse position and initiates the rectangle-drawing mechanism.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
Reimplemented in HOpSelectAreaOOC< SelectionSet >, and HOpSelectArea.
◆ OnLButtonDownAndMove()
|
virtual |
OnLButtonDownAndMove draws a rubberbanded line from the first point in the rectangle to the current mouse position. Note that the basic drawing work is done by HUtility::InsertRectangle, while OnLButtonDownAndMove keeps track of the current points and draws the rubberband centroid.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
◆ OnLButtonUp()
|
virtual |
OnLButtonUp finalizes the size of the rectangle and cleans up.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
Reimplemented in HOpSelectAreaOOC< SelectionSet >, HOpSelectArea, HOpCreateRectangle, HOpCameraZoomBox, and HOpMarkupRectangle.
◆ OnRButtonUp()
|
virtual |
OnRButtonUp passes a right-button up event to OnLButtonUp.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
Member Data Documentation
◆ m_bRectangleExists
|
protected |
