A node that creates a window.
A node that creates a window. The window can either be a native system window or embedded inside another [Window] (see [member Viewport.gui_embed_subwindows]).
At runtime, [Window]s will not close automatically when requested. You need to handle it manually using [signal close_requested] (this applies both to clicking close button and clicking outside popup).
