Oracle Forms Developer – Form Builder Reference, Volume 1

When-Window-Activated trigger
Description
Fires when a window is made the active window. This occurs at form startup and whenever a different
window is given focus. Note that on some window managers, a window can be activated by clicking on
its title bar. This operation is independent of navigation to an item in the window. Thus, navigating to
an item in a different window always activates that window, but window activation can also occur
independently of navigation.
