Activate is a procedure used to signal the OnActivate event handler (if assigned) when the form is activated. Activate is called when the CM_Activate message is handled for the form.
Activate uses an internal member to determine whether the form is being displayed for the first time, or following a change of focus between forms. No actions are performed in the method when the form is being displayed for the first time and the WindowState property contains wsMaximized or wsFullScreen.
Use OnShow to respond to the event notification performed when the form is displayed for the first time.
Use OnChangeBounds or OnResize to respond to delayed changes to the form bounds (position) or resize events.
