/**
|
||||
* The <tt>WindowBackground</tt> is a <tt>JComponent</tt>, which is
|
||||
* added to a <tt>Window</tt> in order to make it transparent.
|
||||
* <p>
|
||||
* <b>How to use the <tt>WindowBackground</tt>?</b>
|
||||
* The <tt>WindowBackground</tt> is created and added to the content pane
|
||||
* of the <tt>Window</tt> that should be made transparent. All other components
|
||||
* then are added to the <tt>WindowBackground</tt> component and not
|
||||
* directly to the window content pane.
|
||||
* <p>
|
||||
* <b>How it works?</b>
|
||||
* The <tt>WindowBackground</tt> is a <tt>JComponent</tt> which is not
|
||||
* really transparent, but only looks like. It overrides the
|
||||
* <code>paintComponent</code> method of <tt>JComponent</tt> to paint its
|
||||
* own background image, which is an exact image of the screen at the position
|
||||
* where the window will apear and with the same size. The
|
||||
* <tt>java.awt.Robot</tt> class is used to make the screen capture.
|
||||
* <p>
|
||||
* Note that the effect of transparence is gone when behind there is an
|
||||
* application which shows dynamic images or something the moves, like
|
||||
* a movie for example.
