IT_SCREEN

IT_SCREEN

Use

The IT_SCREEN structure provides information on the screen that is part of the event. It describes general attributes of the screen, such as its type and size.

The IT_SCREEN structure also points to an array of all the controls on the screen: one IT_CTRL structures for each control.

The parent structure, IT_EVENT, contains only one IT_SCREEN.
