The RTOGGLE gadget (which is very similar to the TOGGLE gadget) is allowed only within FRAMES. You can added them to a FRAME with the usual positioning and layout commands. The RTOGGLE gadgets are implicitly numbered 1,2,3… as they are added.

The FRAME gadget can have an assigned callback, which is executed when the radio group selection is changed, i.e. whenever you select an unselected radio-toggle. As there is only a SELECT action supported, it can be either a simple callback or an open callback.

Note:

offval and onval are string values associated with the radio button states unselected or selected.
Default values are onval = ‘ON’, offval = ‘OFF’.

In order to simplify the task of replacing the use of the (now removed) RADIO gadget by the radio group Frame gadget, the RTOGGLE gadget’s UNSELECT events are raised only if a PML open callback has been defined. This allows the simple replacement of TOGGLE gadgets by RTOGGLE gadgets without the need to modify their callbacks.
