Hi all,
In reply to:

I had a similar problem, causing my forms to "walk" down and to the left.
It was somewhat different in that I was swapping two forms, trying to get them
in the exact same place. It seems that XForms was not allowing for or
getting the window decoration info from my server.
The fix that worked for me was to get the window attributes of the current
window using
XGetWindowAttributes( fl_get_display(), fl_winget(), &win_attribs );
and then calling fl_set_form_position with the following arguments
( Pointer to form I want to open,
X value of current form - win_attribs.x,
Y value of current form - win_attribs.y )
What I think happens is that Xforms says "place my window at x,y" and the server
places the window's decoration at x,y offsetting the actual form by the width
of the decoration's border (x) and title bar (y).
win_attribs.x and win_attribs.y carry the position of the actual window's
upper left corner in relation to the upper left corner of the server's
decoration. In my case it was always 5 and 26. So if I always allowed for
this offset by subtracting these values from my current window's position,
the two forms always stayed in sync.
I'm not an XWindow expert by any means so I may be all wet, however the fix works for me even if it is a bit kludgy. I found that the set geometry command did not work to soleve my problem.
Good luck
Joel
