: '''[winfo] manager''' ''window'' Returns the name of the [geometry manager] currently responsible for ''window'', or an empty string if ''window'' isn't managed by any geometry manager. The name is usually the name of the Tcl command for the geometry manager, such as [pack] or [place]. If the geometry manager is a widget, such as [canvas]es or [text], the name is the widget's class command, such as `canvas`. [Toplevel] windows always return '''[wm]''' because they are managed by the [window manager] (even when withdrawn). ---- **See also** * [grid] * [pack] * [place] * [canvas] * [text] <> Command | Tk syntax help
