viewPage

Procedure that views a new page without hiding the current page. You should run this from application code when you want a user to view a new page that is a separate SmartWindow. viewPage runs changePage to view (and if necessary create) the new SmartWindow, but does not hide the objects on the current page, since they are in a separate window that can be viewed at the same time.

Location: containr.p

Parameters:

INPUT piPageNum AS INTEGER Notes:

Because the previous page is not hidden, the CurrentPage property is reset only temporarily so that changePage knows the new page number; then it is reset to its previous value.
Use the procedure selectPage to hide the current page in a container and view a different one.
Examples:

/* In this example, a SmartWindow has been placed onto page 5 of a    containing SmartWindow. When a button is pressed, viewPage views the    subwindow without hiding anything or changing the current page on the    main SmartWindow. */ ON CHOOSE OF Btn_SubWin DO:   RUN viewPage(5). END.
