Each child of a PanedWindow has a set of
        configuration options that control its position and
        appearance.  These options can be provided when a child
        is added with the .add() method, or set
        with the .paneconfig() method, or queried
        with the .panecget() methods described
        above.
      
Table 28. PanedWindow child widget options
| after | Normally, when you .add()a new
                child to aPanedWindow, the new
                child is added after any existing child widgets.
                You may instead use theafter=option to insert the
                new widget at a position just after an existing
                child widget. | 
| before | When used as option before=in a call to the.add()method, places the new widget at
                a position just before an existing child widget. | 
| height | This option specifies the desired height of the child widget; see Section 5.1, “Dimensions”. | 
| minsize | Use this option to specify a minimum size for the
                child widget in the direction of the PanedWindow's orientation.  Fororient=tk.HORIZONTAL, this is the minimum
                width; fororient=tk.VERTICAL, it is
                the minimum height.  For permissible values, see
                Section 5.1, “Dimensions”. | 
| padx | The amount of extra space to be added to the left and right of the child widget; see Section 5.1, “Dimensions”. | 
| pady | The amount of extra space to be added above and below the child widget; see Section 5.1, “Dimensions”. | 
| sticky | This option functions like the stickyargument to the.grid()method; see Section 4.1, “The.grid()method”.  It specifies how to position a child widget
                if the pane is larger than the widget.  For
                example,sticky=tk.NWwould position
                the widget in the upper left
                (“northwest”) corner of the pane. | 
| width | Desired width of the child widget; see Section 5.1, “Dimensions”. |
