public class CPanelPopup
extends CDecorateableAction

This action shows some kind of popup (for example a JDialog) filled with any content the client likes. This action is intended to be shown as button in a title, but can also be used as menu item in a menu.
Clients may override the various onXYZ-methods and create and show their custom popup. In such a case they should call openPopup(PanelPopupWindow) to ensure that only one window is open at a time.
As long as the user works on the popup-window it does not close automatically, clients can call closePopup() to explicitly close it. The window closes automatically if it loses the focus, clients can call setCloseOnFocusLost(boolean) to change that behavior.
Note: this action does not support being child of a drop down menu
