~~NOTRANS~~ ~~Title: Setting a different window manager~~ The FXDesktopPane supports window manager. The standard window manager shows multiple windows on the desktop and handles global windows. It's also possible to set a window manager for single-window mode. This window manager shows the content as maximized window: desktopPane.setWindowManager(new FXGlobalModalWindowManager(new FXSingleWindowManager())); If you don't need support for global windows: desktopPane.setWindowManager(new FXSingleWindowManager());
