I am not very familiar with the Win32 API (presuming that is what 
GetFocus() is from), but since you talk about tracking events I am 
guessing that it determines which component has the focus.
If that is what you are asking, then there is a better way.  The Window 
class has a getFocusOwner() method that will return the child component 
of the Window that owns the focus.

From a Swing app, you can use the JComponent getTopLevelAncestor() method 
to find the Window that contains a specific component.  Note that this 
method returns a Container, since the "top level ancestor" can be either 
an Applet or a Window.


It is interesting to compare the names of the methods in the Win32 and 
Java APIs.  There is not much question in my mind which naming is better:

    To request that a component be given focus:
        Win32: SetFocus()    Java: requestFocus()

    To get the component that owns the focus:
        Win32: GetFocus()    Java: getFocusOwner()
