The HOpConstructCuboid class creates a rectangular cube.
HOpConstructCuboid implements four of the mouse event handlers defined on the base class and uses the event information to create a cuboid. This provides the basic functionality for creating a temporary three-dimensional, six-sided cuboid or rectangular box. The cuboid that is generated includes two square faces with the same length and width while the depth is variable. The operation consists of the following steps:
More Detailed Description: see event methods.
HOpConstructCuboid::HOpConstructCuboid | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpConstructCuboid 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. |
HBaseOperator* HOpConstructCuboid::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 HOpCreateCuboid.
virtual void HOpConstructCuboid::CreateCuboid | ( | HPoint const & | last | ) | [virtual] |
CreateCuboid constructs the point list from the first, edge and last point and then maps these screen coordinates generated by the event handlers into world coordinates, so that the points can be directed into a call to HC_Insert_Shell. This function is called internally by OnLButtonDown and OnNoButtonDownAndMove.
&last | A pointer to an HPoint object. |
virtual const char* HOpConstructCuboid::GetName | ( | ) | [virtual] |
Reimplemented from HBaseOperator.
Reimplemented in HOpCreateCuboid.
virtual int HOpConstructCuboid::OnLButtonDown | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDown records the first mouse position and initiates the cuboid-drawing mechanism. It tests for the case that the mechanism has already been started such as OnLButtonDown has been called once already. In this case, OnLButtonDown finalizes the cuboid's depth, removes the geometry from the scene, updates the display and ends the operation.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpCreateCuboid.
virtual int HOpConstructCuboid::OnLButtonDownAndMove | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDownAndMove accepts the initiating point from OnLButtonDown and rubberbands a square for the desired size of the cuboid's base.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
virtual int HOpConstructCuboid::OnLButtonUp | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonUp finalizes the size of the cuboid's square base.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
virtual int HOpConstructCuboid::OnNoButtonDownAndMove | ( | HEventInfo & | hevent | ) | [virtual] |
OnNoButtonDownAndMove uses a rubberband to set the desired depth of the cuboid.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
int HOpConstructCuboid::m_FaceList[30] [protected] |
The facelist for the shell.
HPoint HOpConstructCuboid::m_ptEdge [protected] |
The edge of the cube.
HPoint HOpConstructCuboid::m_ptPointList[8] [protected] |
The array of points for cuboid shell.
