Method Detail

stop

void stop()

Called whenever the PreviewPanel should stop i.e. exit. This is usually called whenever the user closes the preview by closing the topic or by opening another topic. The PreviewPanel should release all resources while stopping. This method is usually called from the PreviewWrapper's stop method.

finish

void finish()

getGui

java.awt.Component getGui()

Is called to get the actual preview component. Wandora places the preview component into the user interface of the application. Usually the returned component is JPanel containing various other components such as images and buttons. This method is usually called from the PreviewWrapper. Running the method has no time limit. PreviewWrapper views a loading message and uses a separate thread to call the getGui, preventing the application to freeze.

isHeavy

boolean isHeavy()

This is a deprecated method to tell the preview is a heavy weight AWT component. These days Java can mix heavy weight and swing component, and the isHeavy is not that important any more. Notice, returning a true value actually triggers some additional wrapping for the component returned by the getGui method. See AWTWrapper class for details.
