Description
Specifies the previous page in sequence for dialog. This is for use in multi-page dialogs such as property frames and wizard frames, which typically have Back and Next buttons that let the user navigate forward and backward through the sequence of pages that comprise the dialog.
The default method for the Back button in dialog uses the value of this function. When the Back button is clicked, the current page is set to the previous logical page in the sequence, but you are free to dynamically change it as the state of the dialog changes.
