Alas, the Xtk toolkit is almost completely broken, especially on Suns. It is riddled with null pointer bugs, and the only Widget type that I have yet made work properly is Label. There is no documentation of the interfaces or behaviour of the exisiting Widget types, which is essential for anyone wanting to use it for developing applications; what documentation there is is aimed at those wishing to develop their own Widget types. ButtonBox works for laying out Labels (sometimes), but fails miserably to lay out the other types of Widget I've tried. Officially, I believe the basic toolkit is in Beta and the Widget selection is in Alpha. What this means is that everyone out there should be trying to use it, and fixing the bugs they find, and reporting the fixes to "xbugs". Remember, the only way to make X.11 a success is for everyone to pitch in and help. David. PS - note to whoever is responsible for Xtk: Its really very difficult to decide if something is a bug if there is no description of what, if anything, the thing you suspect the bug is in is supposed to do. PLEASE post to the net anything you have in the way of documentation about the existing widgets - what resources they use, what they are supposed to look like, what their limitations are; anything at all would help to get the toolkit debugged.

Environment: XV11R1 on monochrome Sun 3/50, SunOS 3.2
I am really confused as to what is going in with the Xtk in V11R1.
In the lib/Xtk/clients/ directory there are a few programs that
(I am assuming) are supposed to demonstrate different widgets.
Whenever I start up one of these programs I get several lines of:
Bad source value for 'String' to 'Color' conversion.
Bad source value for 'String' to 'Pixel' conversion.
But eventually a window is created.
The one I am most interested in is the xbuttonbox.
After all of the bad conversion messages I get a window with black
background that seems to have about 5 rectangles that quickly get
covered over with black.
Is the V11 Xtk usable? Are we waiting for fixes?
Surely someone else has come across the same thing, or am I doing
something weird here?
Please help my confusion.

The most common cause for this problem is a missing or invalid rgb
database; check to make sure /usr/lib/X11/rgb.{dir,pag} exist (and check
server/include/site.h to verify the pathname wasn't changed). The -co
server command line argument will also point it at a different database.
As to the overall status of the beta 0.1 toolkit, there is a lot
of cleanup work that is going on (null pointer bugs, etc.) and a lot
more is needed. We will do what we can to make patches available
before the release 2 tape, but mass mailings of patch files will not
be practical due to the volume.mlandau@bbn.com (Matt Landau) (10/29/87)

The -co >server command line argument will also point it at a different database. Nope. The toolkit programs ALWAYS give these error messages when run on a monochrome machine, even if the rgb database is there. The problem is that there's code in lib/oldXrm/XrmConvert.c that ought to be #ifdef'ed out. Comparing lib/oldXrm/XrmConvert.c with lib/Xrm/XrmConvert.c will show you which lines. -- Matt Landau Waiting for a flash of enlightenment mlandau@bbn.com in all this blood and thunder
