Hello Rxantos,

basically all the GUI management is based on events, so if you wan't to do some action if a ctrl changes, use the callbacks of the controls for that (usually the names of the callback members are like : "when...." : WhenAction, WhenPush, ....
You will have to set the callback of all the ctrls you wan't to monitor inside you're dialog.

A nice feature about callbacks is that you can put several actions (callbacks) in one callback !!
You have to use the << operator for this like in this example :

(button.WhenAction << THISBACK(actionOne)) << THISBACK(actionTwo);

This allows you to monitor callbacks while still allowing normal use of the callbacks
