Just assign an event handler to its OnMessage event, and set the Handled
parameter appropriately.

However, do keep in mind that OnMessage will only be triggered for messages
placed in the message queue, such as via PostMessage().  Not for messages
sent to a particular window directly via SendMessage().  Do you need to
intercept though as well?  If so, then you'll mst likely need to use a
message hook via SetWindowsHookEx() instead.

That is what the TApplication::OnMessage event already allows you to do.
