/** @event */ public void add_QueryCursor (QueryCursorEventHandler value) /** @event */ public void remove_QueryCursor (QueryCursorEventHandler value)
In JScript è possibile gestire gli eventi definiti da una classe, ma non è possibile definirne di personalizzati.
This event creates an alias for the Mouse.QueryCursor attached event for this class, so that QueryCursor is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the QueryCursor event are attached to the underlying Mouse.QueryCursor attached event and receive the same event data instance.
The cursor being refered to by this event name is not necessarily the text cursor (sometimes known as the insertion point). Instead, the cursor in this context is the object that declares the onscreen graphical display related to several possible input-related devices or concepts in Windows programming. That object is represented by the Cursor class in WPF. The WPF input system enables you to change this cursor when it represents the onscreen position of the mouse pointer. You can use predefined values from the Cursors enumeration, or you can declare a custom cursor as an image file.
Listening for the QueryCursor event is not an efficient technique for cursor management. Instead, each element should define its own cursor behavior with Cursor and ForceCursor. You should only rely on QueryCursor if you are not using the WPF framework-level base elements, or in extraordinary circumstances where defining cursor behavior on a per-element basis does not meet your needs. For more information on implementing cursor behavior in response to QueryCursor, see QueryCursorEventHandler.
