    Removes a previously added listener interface.
    
    Specified by:
    
    removeMouseListener in interface SourcesMouseEvents
    
    Parameters:
    
    listener - the listener interface to remove
  - removeMouseWheelListener
```
@Deprecated
public void removeMouseWheelListener(MouseWheelListener listener)
```
    Deprecated. Use the HandlerRegistration.removeHandler() method on the object returned by addMouseWheelHandler(com.google.gwt.event.dom.client.MouseWheelHandler) instead
  - setAccessKey
```
public void setAccessKey(char key)
```
    Description copied from interface: Focusable
    
    Sets the widget's 'access key'. This key is used (in conjunction with a browser-specific modifier key) to automatically focus the widget.
    
    Specified by:
    
    setAccessKey in interface Focusable
    
    Parameters:
    
    key - the widget's access key
  - setEnabled
```
public void setEnabled(boolean enabled)
```
    Sets whether this widget is enabled.
    
    Specified by:
    
    setEnabled in interface HasEnabled
    
    Parameters:
    
    enabled - true to enable the widget, false to disable it
  - setFocus
```
public void setFocus(boolean focused)
```
    Description copied from interface: Focusable
    
    Explicitly focus/unfocus this widget. Only one widget can have focus at a time, and the widget that does will receive all keyboard events. NOTE: Most browsers fire FocusEvents asynchronously. Especially within GWT tests, you'll need to make your test asynchronous to properly do verifications. See GWTTestCase#delayTestFinish for more information on how to do this.
    
    Specified by:
    
    setFocus in interface Focusable
    
    Parameters:
    
    focused - whether this widget should take focus or release it
  - setTabIndex
```
public void setTabIndex(int index)
```
    Description copied from interface: Focusable
    
    Sets the widget's position in the tab index. If more than one widget has the same tab index, each such widget will receive focus in an arbitrary order. Setting the tab index to -1 will cause this widget to be removed from the tab order.
    
    Specified by:
    
    setTabIndex in interface Focusable
    
    Parameters:
    
    index - the widget's tab index
  - onAttach
```
protected void onAttach()
```
    Description copied from class: Widget
    
    This method is called when a widget is attached to the browser's document. To receive notification after a Widget has been added to the document, override the Widget.onLoad() method or use Widget.addAttachHandler(com.google.gwt.event.logical.shared.AttachEvent.Handler).
    
    It is strongly recommended that you override Widget.onLoad() or Widget.doAttachChildren() instead of this method to avoid inconsistencies between logical and physical attachment states.
    
    Subclasses that override this method must call super.onAttach() to ensure that the Widget has been attached to its underlying Element.
    
    Overrides:
    
    onAttach in class Widget

    Widget.onLoad(), Widget.doAttachChildren()
