Заметки
When you create an InkCollectorSystemGestureEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.
System gestures give information about the Cursor object that is being used to create the gesture. They also provide shortcuts to combinations of mouse events and are effective ways to detect mouse events.
For example, instead of listening for a MouseUp and MouseDown pair of events with no other mouse events occurring in between, listen for the Tap or RightTap system gestures.
As another example, instead of listening for MouseDown and MouseMove events and getting numerous MouseMove messages, listen for the Drag or RightDrag system gestures, as long as you have no need for the (x, y) coordinates of every position of the mouse. This allows you to receive only one message instead of numerous MouseMove messages.
For a list of specific system gestures, see the SystemGesture enumeration type. For more information about system gestures, see Using Gestures and Command Input on the Tablet PC.
Примеры
The event handler in this example displays system gesture information on a status bar label, statusLabelSysGesture.
Private Sub Event_OnSystemGesture(ByVal sender As Object, ByVal e As InkCollectorSystemGestureEventArgs)
Select Case e.Id
Case SystemGesture.Tap
Me.statusLabelSysGesture.Text = "Tap"
Case SystemGesture.DoubleTap
Me.statusLabelSysGesture.Text = "Double Tap"
End Select
End Sub
private void Event_OnSystemGesture(object sender, InkCollectorSystemGestureEventArgs e)
{
switch (e.Id)
{
case SystemGesture.Tap:
this.statusLabelSysGesture.Text = "Tap";
break;
case SystemGesture.DoubleTap:
this.statusLabelSysGesture.Text = "Double Tap";
break;
}
}
