Syntax:
jframe = getjframe(hFigOrComponent)

Description:
GETJFRAME retrieves the current figure (gcf)'s underlying Java frame, thus enabling access to all 35 figure callbacks that are not exposed by Matlab's figure.

Notable callbacks include: FocusGainedCallback, FocusLostCallback, KeyPressedCallback, KeyReleasedCallback, MouseEnteredCallback, MouseExitedCallback, MousePressedCallback, MouseReleasedCallback, WindowActivatedCallback, WindowClosedCallback, WindowClosingCallback, WindowOpenedCallback, WindowStateChangedCallback and 22 others.

The returned jframe object also allows access to other useful window features: 'AlwaysOnTop', 'CloseOnEscapeEnabled', 'Resizable', 'Enabled', 'HWnd' (for those interested in Windows integration) etc. Type "get(jframe)" to see the full list of properties.

GETJFRAME(hFig) retrieves a specific figure's underlying Java frame. hFig is a Matlab handle, or a list of handles (not necessarily figure handle(s) - the handles' containing figure is used).

Usage examples:
get(getjframe,'ListOfCallbacks'); %display list of supported callbacks
set(getjframe,'WindowStateChangedCallback','disp(''Window min/maxed'')')
set(getjframe,'WindowDeiconifiedCallback',@winMaximizedCallback)
set(getjframe,'WindowIconifiedCallback',{@winMinimizedCallback,mydata})
set(getjframe,'CloseOnEscapeEnabled','on')
jframes = getjframe([gcf,hButton]); % get 2 java frames, from 2 figures

Warning:
This code heavily relies on undocumented and unsupported Matlab functionality. It works on Matlab 7+, but use at your own risk!
