> To support dynamic creation of the Menu for a MenuButton, the
> previewWindowOpen could be reintroduced so that one can populate the Menu
> _before_ the popup window is opened. Today, one can only populate the menu in
> WindowStateListener#windowOpened, ie. after the popup window is displayed.
> This is problematic because correct positioning and sizing cannot be
> determined before the menu is populated. There are probably other use cases
> as well. This one was discussed here:
> http://apache-pivot-users.399431.n3.nabble.com/How-to-create-menu-for-MenuButton-dynamically-td3103392.html
> Code example:
> menuButton.getListPopup().getWindowStateListeners().add(new
> WindowStateListener.Adapter() {
> public Vote previewWindowOpen(Window window) {
> // Populate menuButton's menu
> return Vote.APPROVE;
> }
> }
> I will attach a patch that adds said functionality.
