SyntaxThe SoGestureEvent type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoGestureEvent | Constructor. |
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| GetGestureState | Gets the gesture event state (Begin,Delta,End). |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetNormalizedPosition | Gets the normalized location of the cursor when the event occurred, relative to the specified viewport region. |
| 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. |
| 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. |
| GetTime | Gets the time at which the event occurred. |
| GetTrackerInfo | Gets whether an event object has associated tracker information. |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| SetAltDown | Sets whether the ALT key was down when the event occurred. |
| SetButton1Down | Sets whether mouse Button 1 was down when the event occurred. |
| SetCtrlDown | Sets whether the CTRL key was down when the event occurred. |
| 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. |
| SetShiftDown | Sets whether the shift key was down when the event occurred. |
| SetTime | Sets the time at which the event occurred. |
| ToString | Returns a string that represents the current object. (Inherited from 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.Gestures.Events.SoGestureEvent represents a series of touch events beginning with begin state and finishing with end state. It is the base class for gesture events in the Open Inventor model. Gesture events can be handled using (for example) an OIV.Inventor.Nodes.SoEventCallback node.
All touch events are analyzed by recognizers. When a gesture is recognized, the recognizer generates the corresponding event. This class stores the begin/delta/end state of the gesture when the event occurred.
Note:
In order to get touch events for the gesture recognizer(s) to recognize, the application must explicitly register a touch screen device (OIV.Inventor.Touch.Devices.SoWinTouchScreen, SoQtTouchScreen, etc).
In order to get gesture events, the application must explicitly register gesture recognizers with the touch screen device's touch manager (OIV.Inventor.Touch.SoTouchManager).
