Description

Occurs when the form becomes active.

Use OnActivate to perform special processing when the form receives focus. A form becomes active when focus is transferred to it (when the user clicks on the form, for example).

Note: The OnActivate event of the application (TApplication), not the form, occurs when Windows switches control from another application.
