Method Detail

finish

public void finish()

Specified by:

finish in interface PreviewPanel

stop

public void stop()

Description copied from interface: PreviewPanel

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.

Specified by:

stop in interface PreviewPanel

isHeavy

public boolean isHeavy()

Description copied from interface: PreviewPanel

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.

Specified by:

isHeavy in interface PreviewPanel

getTextComponent

protected javax.swing.JComponent getTextComponent(java.lang.String locator)
                                           throws java.lang.Exception

Throws:

java.lang.Exception

getGui

public javax.swing.JPanel getGui()

Description copied from interface: PreviewPanel

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.

Specified by:

getGui in interface PreviewPanel

getContent

protected java.lang.String getContent(java.lang.String locator)
                               throws java.lang.Exception

Throws:

java.lang.Exception

getJToolBar

protected javax.swing.JComponent getJToolBar()

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent actionEvent)

Specified by:
