Hello,
I would like to know how we could simply make several toggle buttons
acting like radio buttons, or even having a group of toggle buttons
which they read automatically their state into a common model when an
external event occurs on the group^itself...
regards
Xavier

Write the code to do this?

Seriously, listen for SWT.Selection on every button. When a button is
selected, go through a list of toggle buttons (possibly queried from the
parent using "getChildren()" then filtered with "control.instanceof Button
&& (control.getStyle() & SWT.TOGGLE) != 0" to get only the toggle buttons.
For any button that is not the one in the callback, use
"setSelection(false)" to turn off the selection in the old button and
"setSelection(true)" to turn it on for the one in the listener ... oh heck,
here's the code ...
