ovi_GetSetVisible (getSet;overlayRef;visible) <- errorCode

Parameter Type Description

<- errorCode Long Integer Error Code (0 = no error)


overlayRef is a reference to an overlay window returned by ovi_NewWindow.

If getSet is 0 (constant kovi_GET), the routine returns 0 in visible if the window is invisible, else it returns 1.

If getSet is 1 (constant kovi_SET), the routine set the visible of the window: it is invisible if visible is 0 else it is visible.

NOTE: when ovi_NewWindow is called, the window is initially invisible.
