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:
HOpConstructRectangle::HOpConstructRectangle | ( | HBaseView * | view, | |
int | DoRepeat = 0 , |
|||
int | DoCapture = 1 , |
|||
bool | UseCenterMarker = true | |||
) |
Constructs an HOpConstructRectangle 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 render a mark at the center of the rectangle. |
virtual HBaseOperator* HOpConstructRectangle::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 HBaseOperator.
Reimplemented in HOpCameraZoomBox, HOpCreateRectangle, HOpMarkupRectangle, and HOpSelectArea.
virtual const char* HOpConstructRectangle::GetName | ( | ) | [virtual] |
Reimplemented from HBaseOperator.
Reimplemented in HOpCameraZoomBox, HOpCreateRectangle, HOpMarkupRectangle, and HOpSelectArea.
virtual int HOpConstructRectangle::OnLButtonDown | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDown records the first mouse position and initiates the rectangle-drawing mechanism.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpSelectArea.
virtual int HOpConstructRectangle::OnLButtonDownAndMove | ( | HEventInfo & | hevent | ) | [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.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
virtual int HOpConstructRectangle::OnLButtonUp | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonUp finalizes the size of the rectangle and cleans up.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpCameraZoomBox, HOpCreateRectangle, HOpMarkupRectangle, and HOpSelectArea.
virtual int HOpConstructRectangle::OnRButtonUp | ( | HEventInfo & | hevent | ) | [virtual] |
OnRButtonUp passes a right-button up event to OnLButtonUp.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
bool HOpConstructRectangle::m_bRectangleExists [protected] |
The boolean indicating whether the rectangle exists.
HPoint HOpConstructRectangle::m_ptRectangle[2] [protected] |
The first and last points in the rectangle stored in window space.
