Responding To Group Boxes

When an event occurs that might change the group box's selections (for example, when a user clicks a button or the application calls Check), Windows sends a notification message to the group box's parent window.

The parent window can intercept the message for the group box as a whole, rather than responding to the individual selection boxes in the group box. To find out which control in the group was affected, you can read the current status of each control.
