InkCollector.MouseDown Event
Occurs when the mouse pointer is over the InkCollector and the user presses a mouse button.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
Syntax
'Declaration
Public Event MouseDown As InkCollectorMouseDownEventHandler
'Usage
Dim instance As InkCollector
Dim handler As InkCollectorMouseDownEventHandler
AddHandler instance.MouseDown, handler
public event InkCollectorMouseDownEventHandler MouseDown
public:
event InkCollectorMouseDownEventHandler^ MouseDown {
void add (InkCollectorMouseDownEventHandler^ value);
void remove (InkCollectorMouseDownEventHandler^ value);
}
JScript does not support events.
Remarks
The event handler receives an argument of type CancelMouseEventArgs that contains data about this event.
When you create an 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.
Note
Some controls rely on a specific relationship between MouseDown, MouseMove, and MouseUp events. Canceling some of these events may have unanticipated results.
