If you've ever customized your .Xresources file, then you already know a
lot of what you need for Motif programming.  If you haven't learned
about X resources, you should first look in the Athena OLC stock
answers, because we won't cover that material in this course.

		How to use X RESOURCES

Let's look at how you can create the layout of a Motif application
entirely in X resources.  Type the following at the athena% prompt:

	setup wcl

A new xterm will appear, giving you a wcl% prompt.  At the wcl% prompt,
type the following commands:

	cd /mit/wcl/app-defaults
	Mri -rf Mri/Demo &

You'll get a window with a stack of buttons.  Try clicking the top one,
"Hello".  A window will pop up that might look like the first X-windows
program you ever wrote.  In your xterm window you'll see something like

	wcl% Wcl loaded: Mri/Hello

Take a look at that file (type "more Mri/Hello").  Ignore the lines
beginning with `!'; they're just comments.  "Hello World" is just four X
resources.  The first resource tells Mri to create one widget: "push"
The next line says that "push" should be a Motif PushButton.  If you
want lots of gory details, type "man XmPushButton" (the capital letters
are important).  The third line puts a label on the PushButton.  The
fourth line tells what to do when the button is clicked on.

Take a few minutes to browse through the other demo programs,
particularly PerTem.

Next, I will give you an example of how to write a mockup of your own
application in X resources with Mri.  Type
