xperts,
Has anyone run XView applications (based on X11R4) and displayed them on
Dec (running X11R3)? Orignally when doing this I received some font errors
which I resolved and then I received the following error msg:
XView warning: xv_rop: can't handle drawables of different depth
XView warning: xv_rop: xv_rop_internal failed
X Error: BadAtom
Request Major code 17 ()
Request Minor code 0
ResourceID 0x7f0000
Error Serial #383
Current Serial #383
The application actually displays, but once an event occurs, the above
message is produced.
Anyone have any suggestions? Should this be feasible?
Thanks in advance,

We at ECMWF has had the same problem. It seems that the DEC server does not know
about the extended event types defined by the ICCCM. The event gets messed up,
but the funny thing is that the result depends on the window manager you are
running. Fortunately some people are kind enough to give you the sources ...
and there is a way around the problem.
We run this patch for DECstation 5000 / ULTRIX 4.0
To be able to run SUN XView programs on a SUN, displaying the window on a
DECstation you have to do the following.
1. Get the source of xview.
2. Patch the file : xview2/lib/libxvin/win/win_input.c
The patches are included.
3. Do a make world.
4. When you want to run an xview application you change the LD_LIBRARY_PATH
We use:
setenv LD_LIBRARY_PATH "/home/unix/xview2/lib/libxview:$LD_LIBRARY_PATH"
Note that you also need some OpenLook fonts.
The patch:
A quick and dirty patch to win_input.c is enclosed.
Two parts of the event processing is patched.
a) Drag and drop events.
The positions gets garbled up, I have not found a way to patch the
positions. These events are ignored.
b) Focus and delete-window. Mapped to correct values for different
window managers.
If the env. variable DEC_XVIEW_DEBUG is defined the events are printed.
If the "return (result);" statement in the patch for lines: 1561,1586 is
removed, XView programs on SUN servers will run without side-effects.
