Method Detail

onPanelCreate

public void onPanelCreate(VirtualPanel panel)

Called to initialize the panel before it is displayed.

Specified by:

onPanelCreate in interface VirtualPanelListener

onPanelDestroy

public void onPanelDestroy(VirtualPanel panel)

Called to inform the listener that the panel is destroyed.

Specified by:

onPanelDestroy in interface VirtualPanelListener

onPanelClosing

public boolean onPanelClosing(VirtualPanel panel)

Called when the close button of a panel is pressed, but before any other processing has been done. If this function returns false, the application close object will be called (if defined), otherwise a faked keypress of the Escape key is performed. If these two actions failed (because there is no close object or no button or menu item is connected to the Escape key), then the function onPanelClose is called.

Specified by:

onPanelClosing in interface VirtualPanelListener

Returns:

false to proceed with default processing,
true to cancel closing of the panel.

See Also:

onPanelClose(se.entra.phantom.server.VirtualPanel)

onPanelClose

public boolean onPanelClose(VirtualPanel panel)

Called when the close button of a panel is pressed. When a panel has a listener attached to it, it will not perform default close operations. The listener should dismiss or destroy the panel unless cancelling of the panel is not permitted.

Specified by:

onPanelClose in interface VirtualPanelListener

Returns:

false to proceed with default processing,
true to stop processing panel close.

See Also:

onPanelClosing(se.entra.phantom.server.VirtualPanel)

onPageActivated

public void onPageActivated(VirtualPanel panel)

Called when a notebook page becomes active due to user interaction. This call is directed to the notebook page listener.

Specified by:

onPageActivated in interface VirtualPanelListener

onFocusGained

public void onFocusGained(VirtualPanel panel,
                          VirtualControl control,
                          String controlID)

Controls that can receive input focus generates this event when they gain focus.

Specified by:

onFocusGained in interface VirtualComponentListener

onFocusLost

public void onFocusLost(VirtualPanel panel,
                        VirtualControl control,
                        String controlID)

Controls that can receive input focus generates this event when they lose focus.

Specified by:

onFocusLost in interface VirtualComponentListener

onContentChanged

public void onContentChanged(VirtualPanel panel,
                             VirtualControl control,
