Hi all,

When a Windows application lost focus, it's title bar will become
gray(in WinXP).
I have twin process application�� I hope one process has focus, the
other process' title bar is still blue.

I don't want to draw the title bar myself. Is there any flag I can
control to maintain the blue state when user focus come to any process of
mine?


Thanks in advance to anyone who can help!

Bar drawing the title yourself, I don't think so.

But note: the whole purpose of title bar colors (which of course
aren't necessarily blue/gray on XP and are certainly not that on Vista
+) is to inform the user what top-level window has focus. You seem to
want to break that. Why do you want to break the way your user's
machines work? These are not your machines, you can't do what you want
with them.

Instead, you should perhaps say why you want to do that (or better
yet, what you really want). Perhaps there's some less nefarious way to
get that.

Is it that that you want your user to notice that there are other
related windows to the one that has focus? You could do that e.g. by
blinking some UI element on them when you change focus.

But please don't break normal system mechanics on a whim.

Goran.

I don't recommend doing this, as your users are sure to complain about your
non-standard app causing them confusion, but technically use Spy++ to see
which windows messages your frame (topmost) window gets when it loses focus.
I believe it receives WM_ACTIVATE, WM_KILLFOCUS, etc. If you handle those
and don't forward them to the base class, then perhaps your title bar won't
be redrawn.
