Release 10.1A: OpenEdge Development:
ADM and SmartObjects

> ## Page SmartLink

> The Page SmartLink’s source object can inform its target object that a new page has been selected. The source also can manage an interface for selecting pages (such as tab folders).

> To maintain a Page SmartLink, the ADM requires the source object to `SUBSCRIBE` to and implement the events shown in Table 3–4. Specifically, the Page-Source `SUBSCRIBE`s to target events in the Page-Target procedure handle, and must implement the corresponding internal procedures.

> Table 3–4: Page events
> PageSourceEvents | PageTargetEvents
> --- | ---
> – (None) |
>     changeFolderPage
>     deleteFolderPage

> The Page relationship typically connects the following types of SmartObjects:

> - Source — SmartFolder

> - Target — SmartContainer, SmartWindow, SmartFrame, SmartDialog
