Note:
Please
see the demo. It is really difficult to explain what the
PageManager does in English as most of the operations are taken
care of by Borland's tNoteBook.
In other words, PageManger acts as a middle-man between buttons
assigned to OkButton, CancelButton, HelpButton and tNoteBook.
Description:
TPageManager gives
you the possibility of "one-click" creating
"step-by-step" dialogs (known as "experts" or
"wizards"). The database form Wizard dialog is a
typical example of that. This component has no pages, it uses
another page owner defined by PageOwner property. Currently only
TNotebook is supported as page owner.TPageManager has
OnGetNextPage and OnGetPriorPage events to handle sequence of
pages. Also TPageManager has PageProxies property which contains
list of page proxies («steps»), each of them has OnEnter,
OnShow, OnHide è OnLeave events. These events occur when the
user clicks the Back and Next buttons specified by NextBtn and
PriorBtn properties. You can also change current page
programatically by calling NextPage and PriorPage methods.
