| // CLASS: CFileDialogEventHandler | ||
| // | ||
| // PURPOSE: | ||
| // File Dialog Event Handler that responds to Events in Added Controls. The | ||
| // events handler provided by the calling process can implement | ||
| // IFileDialogControlEvents in addition to IFileDialogEvents. | ||
| // IFileDialogControlEvents enables the calling process to react to these events: | ||
| // 1) PushButton clicked. | ||
| // 2) CheckButton state changed. | ||
| // 3) Item selected from a menu, ComboBox, or RadioButton list. | ||
| // 4) Control activating. This is sent when a menu is about to display a | ||
| // drop-down list, in case the calling process wants to change the items in | ||
| // the list. | ||
