3 | This class represents the events generated by a notebook control: currently, |
| 4 | there are two of them. The PAGE\_CHANGING event is sent before the current | |
| 3980000c | 5 | page is changed. It allows the program to examine the current page (which |
| 4d0f3cd6 | 6 | can be retrieved with |
| 8771a323 | 7 | \helpref{GetOldSelection()}{wxnotebookeventgetoldselection}) and to veto the page |
| 4d0f3cd6 VZ |
8 | change by calling \helpref{Veto()}{wxnotifyeventveto} if, for example, the |
| 9 | current values in the controls of the old page are invalid. | |
| 10 | ||
| 11 | The second event - PAGE\_CHANGED - is sent after the page has been changed and | |
| 12 | the program cannot veto it any more, it just informs it about the page change. | |
| 13 | ||
| 14 | To summarize, if the program is interested in validating the page values | |
| 15 | before allowing the user to change it, it should process the PAGE\_CHANGING | |
| 16 | event, otherwise PAGE\_CHANGED is probably enough. In any case, it is probably | |
| 17 | unnecessary to process both events at once. | |
