Method Detail

init

public void init(StormBase base)

When the callback is given to StormBase, it initializes the callback with this call.

createTopLevelContainer

public Container createTopLevelContainer(Viewport viewport)

Create a new top-level browser window and return an awt container that can be used by StormBase for placing pilots. If the application does not want a new window to be displayed, it can return null.

disposeTopLevelContainer

public void disposeTopLevelContainer(Viewport viewport)

When the StormBase wants to close the viewport, the application is notified about this so it can terminate the browser window associated with this viewport.

public void processViewportMessage(Viewport view,
                                   String messageName,
                                   Object addArg,
