What I am trying to do is put a combo box in the middle of the gridpane, and a clock on the right. I would like to use the the gridpane, and HBox and VBox. I just don't

问题 My app, if I click the "maximize button", it will maximize the window. But if I go to another scene(in the same stage), the window will restore to the original size.

It keeps other scenes maximizing. 回答2: I had the same problem. I fixed it creating a root stage with that only contains a menu bar and a tool bar, like this: I initialized this window in

问题 If a ContextMenu has lots of items, it fills the entire screen. It seems that ContextMenu.setMaxSize has no effect whatsoever. Is there a way to restrict the size of a ContextMenu , in a way that it is still scrollable via mouse wheel & and the up and down buttons appear? I guess I could roll my own control with VBox & Scrollpane, but I'd like to avoid this if possible. 回答1: Unfortunately, limiting the size of popup is not supported: the Region that's responsible for showing the MenuItems is
