If your apps really *need* 256colors, you need to change the output
settings of the server in X11 preferences to 256 colors and restart
the server. 8bit visuals in the TrueColor server are buggy.

Whoa there is so much traffic lately it is hard to keep up.
One thing is that maybe ximtool is owning the colormap. So when you
click on it it gets focus and the colors now appear right. Possibly
you had focus follows mouse on before?
Also I tried the 256 color apps I need recently and they seemed to
work fine, but they only use maybe 8 colors.

Sorry I did not answer that question. The answer is yes, I set the
output
in preferences to 256 color mode and when I type " defaults read
org.x.x11
depth" I get '8'.

Please answer my other question as well.
Are you *REALLY* using 256 color mode in X11? What is the output if
you run 'defaults read org.x.x11 depth'? Check X11->Preferences-
Output->Colors.

This did work on Tiger, I just tested it again today on a Tiger
system. The
ximtool program does use 8-bit pseudocolor.
The switch will happen on mouse over if you set focus-follows-
mouse,
otherwise you do have to click in the window.

are some problems with the color maps that I haven't traced down
yet,
so the colors will be off).
Did this "color to grey" work in X11 on Tiger? I don't think we
supported an 8bit grayscale visual. Or is it actually using
PseudoColor 8bit grey colormap?
Is your problem that the switch is happening "on click" rather
than
"on mouse over"? If so, I come back to wondering if this worked
on
Tiger or not. The window should be getting notifications of mouse
entering or leaving just like any other X11 application does.

I just tried ximtool with the new 256 color mode and it does not
work
properly. Ximtool is a display tool for astronomy which operates
only in
256 color mode. Normally when you put your mouse within the
window
the
color map gets switched to 256 greys, when you go out of the
window
the
colors get remapped to the color mode used by the active window.
With the
latest release of X11 the color map will not switch when you
activate the
ximtool window. It will switch if you use the mouse to draw a
cursor on the
image, then the redrawn area within the cursor will have the
correct
color
map. But it will not automatically switch when the mouse
enters the
window.
There is another feature of ximtool which also does not work
and is
probably
related. When the cursor is within the image area and you
press on
the
right mouse button and move the mouse the color map is supposed
to
update in
real time changing the greyscale mapping (it adjusts the contrast
and
display range). The right mouse button does get sent to the
program
because
other right mouse button functions work as expected but the
remapping of the
colors does not function.
Jeremy, I apologize for not testing this during the rc phase
but I
was using
X11 for some critical work and I did not want to take the
chance of
breaking
anything. This is not a critical issue for me because I have
migrated to
ds9 for most display tasks but I would like to see ximtool work
once
again
if possible (it has not worked since the old tiger 256 color mode
was
nixed).
