Hello everyone,
I know this problem is well known and has been discussed several
times, however I hope you can help me.
I'm developing a software which is meant to be run as a .sav in
several OS's. To try and minimize our problems we have have set an
optimal window size, so that we can at least try to dimension our
display correctly, without having to worry about different screen
sizes.
Nonetheless we cannot guarantee that all screen resolutions will match
the one we choose, so we decided that for smaller windows scroll bars
should be included.
In terms of code we have something like this:
base = WIDGET_BASE(/ROW, XSIZE = qm_defaultXsize, YSIZE =
qm_defaultYsize, $
/SCROLL,SCR_XSIZE = (scrsize[0]-qm_xscrollpad), SCR_YSIZE =
(scrsize[1]-qm_yscrollpad), $
TITLE = 'QuasiManager developed by Quasi-Software
Company@IBEB.pt')
However when running the program in Linux machines part of the window
which is not immediately visible is not correctly rendered. We have
tried it in Windows and it renders as expected. When we use Redhat the
window renders the parts which are not visible in x, but doesn't do
so in y.
Does anyone have any idea why this might be happening?
Thank you in advance!

Yikes! I don't know. Can you catch an event from
the scroll bars (I doubt this, but I don't have
time to check this morning) and issue a redraw of
your widget hierarchy:
Widget_Control, event.top, /Realize
Maybe you have to put a Refresh button in a location that
*will* appear on the display always.
Don't know. Tough problem. :-(
Let us know if you figure something out.
Cheers,
David
