Details
The function action should take one argument, which should be the panel to which the radiobuttons are attached.
See rp.grid for details of the grid layout system.
Value
If the argument panel is the panelname string, the same string is returned. If the panel object is used, the altered panel is assigned to both the calling level and panel's environment
level.
Warning
The action function should return the panel. Without this assignment any widgets added or alterations made to panel parameters within the action function will be lost.
