The HOpObjectRotate class rotates a selected object.
HOpObjectRotate implements three of the mouse event handlers defined on the base class and utilizes the event information to rotate the currently selected objects. This provides the basic functionality for applying a rotation transform to an object (as opposed to a global camera transform which affects the entire scene). The operation consists of the following steps:
More Detailed Description: see event methods.
HOpObjectRotate::HOpObjectRotate | ( | HBaseView * | view, |
int | DoRepeat = 0 , |

int | DoCapture = 1 |

) |
Constructs an HOpObjectRotate 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 |
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.

OnLButtonDblClk moves the object back to its original location
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
|
virtual |
OnLButtonDown draws a bounding box around the object to be rotated. It records the mouse position and sets up the transform environment.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
|
virtual |
OnLButtonDownAndMove computes the rotation transform based on the distance between the first and current pointer positions, and rotates the object accordingly.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
|
virtual |
OnLButtonUp cleans up the construction segments used during the transformations.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
