|
A validator has up to three purposes:
|
||
|
|
|
||
|
|
1) To validate the data in the window that's associated
|
||
|
|
with the validator.
|
||
|
|
2) To transfer data to and from the window.
|
||
|
|
3) To filter input, using its role as a wxEvtHandler
|
||
|
|
to intercept e.g. OnChar.
|
||
|
|
|
||
|
|
Note that wxValidator and derived classes use reference counting.
