Changing the font used by a System.Windows.Forms.ContainerControl will cause the layout to be recalculated and reapplied to the contained controls if the ContainerControl.AutoScaleMode property has a value of AutoScaleMode.Font.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The ContainerControl.OnFontChanged(EventArgs) method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
