SyntaxThe SoControllerButtonEvent type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoControllerButtonEvent | Constructor. |
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| GetButton | Get which button generated the event. |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetNormalizedPosition | Gets the normalized location of the cursor when the event occurred, relative to the specified viewport region. |
| GetOrientation | Get orientation of associated tracker as a standard Open Inventor rotation (quaternion). |
| GetPosition | Returns the window pixel location of the cursor when the event occurred as integer values. |
| GetPosition(SbViewportRegion) | Gets the viewport pixel location of the cursor when the event occurred, relative to the origin of the specified viewport region, as integer values. |
| GetPosition3 | Get position of associated tracker in world coordinates. |
| GetPositionFloat | Returns the window pixel location of the cursor when the event occurred as float values. |
| GetPositionFloat(SbViewportRegion) | Gets the viewport pixel location of the cursor when the event occurred, relative to the origin of the specified viewport region, as float values. |
| GetRay | Get a ray for picking/intersecting. |
| GetState | Gets the state of the button. |
| GetTime | Gets the time at which the event occurred. |
| GetTrackerInfo | Gets whether an event object has associated tracker information. |

 | IsButtonPressEvent | Convenience function to see if an OIV.Inventor.Events.SoEvent is a press of the passed mouse button. |
| IsButtonReleaseEvent | Convenience function to see if an OIV.Inventor.Events.SoEvent is a release of the passed mouse button. |
| SetAltDown | Sets whether the ALT key was down when the event occurred. |
| SetButton | Set which button generated the event. |
| SetButton1Down | Sets whether mouse Button 1 was down when the event occurred. |

| SetOrientation(SbVec3f, Single) | Set orientation value of associated tracker from axis and angle in radians. |
| SetOrientation(Single, Single, Single) | Set orientation value of associated tracker from Euler angles in radians (using the trackd convention Z*X*Y). |
| SetPosition(SbVec2f) | Float version of OIV.Inventor.Events.SoEvent.SetPosition(OIV.Inventor.SbVec2s). |
| SetPosition(SbVec2s) | Sets the window pixel location of the cursor when the event occurred. |
| SetPosition3 | Set position of associated tracker in world coordinates. |
| SetShiftDown | Sets whether the shift key was down when the event occurred. |
| SetState | Sets the state of the button. |
| SetTime | Sets the time at which the event occurred. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| TrackerInfo | Get the OIV.Inventor.SbTrackerInfo object. |
| WasAltDown | Returns true if the ALT key was down when the event occurred. |
| WasButton1Down | Returns true if mouse button 1 was down when the event occurred. |
| WasCtrlDown | Returns true if the CTRL key was down when the event occurred. |
| WasShiftDown | Returns true if the shift key was down when the event occurred. |
RemarksOIV.Inventor.Events.SoControllerButtonEvent represents controller button press and release events in the Open Inventor event model. A controller device generally has associated 3D tracker information.
A "tracker" is any device whose position and orientation are dynamically tracked in 3D, typically for immersive VR applications. For example: a head tracker. A "controller" is an input device which typically has buttons and/or valuators (e.g. a joystick). Many controllers have an associated tracker. For example, the commonly used "wand" input device has three buttons, a two-axis joystick (two valuators), and an associated tracker.
The virtual method OIV.Inventor.Events.SoEvent.GetTrackerInfo() can be used to determine if an event object has associated tracker information. Traditional 2D events like OIV.Inventor.Events.SoMouseButtonEvent and OIV.Inventor.Events.SoLocation2Event return NULL. 3D events like OIV.Inventor.Events.SoTrackerEvent and OIV.Inventor.Events.SoControllerButtonEvent return a their associated tracker information (OIV.Inventor.SbTrackerInfo).
Many controller devices generate a continuous stream of data, so strictly speaking there are no "events". However Open Inventor classes that recognize the OIV.Inventor.Events.SoControllerButtonEvent interpret it as notification of a change in the button state (press or release). The application (or other software above Open Inventor) is responsible for deciding when to actually create an OIV.Inventor.Events.SoControllerButtonEvent.
