How to detect radioBox button selection after launching DB ?

I am writing a dxl that launches a dialog box which has multiple fields/tabs etc. .

I would like to find a way to enable my dxl to know when a user has selected a certain radioBox selection.

Currently, I am using an extra Dialog box button for " update " purposes. Currently, whenever the user selects a different radio selection they must then press this other button so that the call-back function executes.

Ideally, I would like the user to be able to select a different radioBox selection and have the dxl automatically execute a call back function.

Does anyone know of a way to do this?

A screen shot is attached if you would like to see what the box looks like. The "update" button and the current radio selections are highlighted.
Thanks

In DXL all dialog box elements support an 'on change' callback, that can be defined using 'set'.
 

string toppings[] = { "Beef", "Cheese", "Pepperoni", "Sausage" }
DB pizzaDB = create "Pizza Box"
DBE radioBoxDBE = radioBox (pizzaDB, "Topping", toppings, 2)
DBE myList      = list (pizzaDB, "Topping", 150, 3, toppings, 4)
// callback that will be called when the radio box value changes
void doRadioBox(DBE dbe) {
    int nr = get radioBoxDBE
        print "Topping " (toppings[nr]) ".was selected ...\n"
}
 
void doSelectList (DBE dbe) {
        int nr = get myList
        print "List selection changed: " toppings[nr] "\n"
}
 
void doActivateList (DBE dbe) {
        int nr = get myList
        print "List Activation: " toppings[nr] "\n"
}
 
set(radioBoxDBE, doRadioBox)    // set 'change' callback 
set(myList, doSelectList, doActivateList) // lists support single click and double click callbacks
 
show pizzaDB

You can do the same for checkboxes,fields, date pickers, etc. Hope that helps, regards, Mathias
