I have written a program and it has a window in a window.  The two are intended
to be joined together so I made the one on top a pane.

But when the user clicks on the top of the back window I get an open event and
then have to open the other in front again.  Thus when the user holds the title
bar the pane flashes (albeit very fast)

Can someone tell me how it should be done ?

THis stuff about panes reminds me.

What is the *advantage* of defining a window to be a pane? I mean, when you
move the parent window, you have to move the pane *yourself* -- the WIMP
doesn't do it for you. What does making it a pane give you over making it an
ordinary window and tracking opens of its logical parent?

I read the WIMP section of the PRM several times, looking for an answer, some
time ago, but found one not. Can anyone enlighten me?

My technique for opening panes is, on getting the redraw request:

1. <behind>= "handle of window to open behind" field from open request

2. Calculate position of Pane 1 (don't corrupt data for main window)
3. Open Pane 1 behind <behind>
4. <behind> = Pane 1 handle

5. Repeat steps 2-4 for subsequent panes

6. Open main window behind <behind>

Oh yes - ignore "Open Window Requests" for panes.
This seems to work without any flickering, although "solid drags"
of a window+pane combination are never quite as smooth as a single
window.
