[]How make two CaptionBar sincronized?

[Marco]

I have an application and its ToolBar in another window.
When is focused the first is not the second and vice
versa.
I would make both focused if i focus one or both
unfocused if i click on whatever part on the Screen.
How?

P.S. for an example see Photoshop and its tool, or
Fireworks and so on...

Tnx

Please give me some advise about this.
I explain better the question:
I made an application with a toolbar in a separate window.
when i click on the toolbar, my main application lose the
focus, and vice versa.
I need to get simultaniously the focus for the two
windows, and lose both if i click outside of these.
How can i implement this?
