where layoutwindow is the Tk pathname of the layout window (not the top-level frame).
The caption command is used by the GUI wrapper script and is normally not a user command. It configures the titlebar of the wrapper frame in a way that is similar to the titlebar in the original (non-Tcl, non-GUI) versions of magic. The style and contents of the titlebar may be changed by redefining this procedure in Tcl.
caption is implemented as a Tcl script in the GUI wrapper.
