Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in microsoft.ink.dll)

Syntax

'Declaration
Public Event MouseWheel As InkCollectorMouseWheelEventHandler
'Usage
Dim instance As InkOverlay
Dim handler As InkCollectorMouseWheelEventHandler

AddHandler instance.MouseWheel, handler

public event InkCollectorMouseWheelEventHandler MouseWheel

public:
event InkCollectorMouseWheelEventHandler^ MouseWheel {
    void add (InkCollectorMouseWheelEventHandler^ value);
    void remove (InkCollectorMouseWheelEventHandler^ value);
}

/** @event */
public void add_MouseWheel (InkCollectorMouseWheelEventHandler value)

/** @event */
public void remove_MouseWheel (InkCollectorMouseWheelEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.

Not applicable.

Remarks

The event handler receives an argument of type CancelMouseEventArgs containing data about this event.

When you create a InkCollectorMouseDownEventHandler 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. For performance reasons, the default event interest is off but is turned on automatically if you add an event handler.

To improve real-time ink performance, hide the mouse cursor while inking. To do so, hide the mouse cursor in the MouseDown event handler, and show the mouse cursor in the MouseUp event handler.

Note

The CancelMouseEventArgs object's X and Y properties are in pixels and not the HIMETRIC units that are associated with the ink space. This is because this event replaces the related mouse event of an application that is not pen-aware, and that type of application is depicted in pixels.
