Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Function GetGestureStatus ( _
    gesture As ApplicationGesture _
) As Boolean
'Usage
Dim instance As InkPicture 
Dim gesture As ApplicationGesture 
Dim returnValue As Boolean 

returnValue = instance.GetGestureStatus(gesture)

public bool GetGestureStatus(
    ApplicationGesture gesture
)

public:
bool GetGestureStatus(
    ApplicationGesture gesture
)

public function GetGestureStatus(
    gesture : ApplicationGesture
) : boolean

Parameters

gesture
Type: Microsoft.Ink.ApplicationGesture

A member of the ApplicationGesture enumeration that represents the gesture to query about.

Return Value

Type: System.Boolean
Whether the InkPicture control has interest in a particular application gesture.

Value	Meaning
true	The InkPicture control has interest in the gesture. The Gesture event is raised when the gesture is recognized.
false	The InkPicture control has no interest in the gesture.

Remarks

This method throws an exception if the gesture parameter is set to AllGestures

To set interest of the InkPicture control for a particular gesture, call the InkPicture.SetGestureStatus method

Note

By default, the InkPicture control does not have interest in any application gesture

Examples

This C# example creates an ArrayListthat contains all application gestures for which an InkPicture control, theInkPicture, has interest.

[C#]

using Microsoft.Ink;
// . . .
// Return an array of all of the ApplicationGestures that
// have their status set to true on the InkPicture control.
private ApplicationGesture [] GetSetAppGestures(InkPicture theInkPicture)
{
    ArrayList result = new ArrayList();
    Array gestureArray = System.Enum.GetValues(typeof(ApplicationGesture));
    foreach (ApplicationGesture theGesture in gestureArray)
    {
        // ApplicationGesture.AllGestures is not a meaningful
        // gesture to pass to GetGestureStatus()
        if (theGesture != ApplicationGesture.AllGestures &&
        theInkPicture.GetGestureStatus(theGesture))
        {
            result.Add(theGesture);
        }
    }
    return (ApplicationGesture[])result.ToArray(typeof(ApplicationGesture));
