#7 setTitle for JFRame in Swing.scm

[Bill Hale]

First, I am not compiling Swing.scm to java.
I am just loading Swing.scm itself.

I noticed that setTitle for JFrame does not work.

I saw two problems.

1) Since JFrame is a component, the following
case statement will detect JFrame as only
a component, not as a JFrame:

=========================================
(define (processConArgs c as)
(define (processConArg c a)
(class-case (c a)
((java.awt.Component java.lang.String)
(writestring c a))
....
=========================================

2) But, even that would not be so bad
if "writestring c a" would handle
the JFrame component, possibly like:

=========================================
(define (writeOneString Comp Arg)
(class-case (Comp)
((javax.swing.JFrame) (.setTitle Comp (.toString
Arg)))
((javax.swing.JButton) (.setLabel Comp (.toString
Arg)))
....
=========================================

Also, changes for "readOneString" should
handle JFrame also.

If changes like the above are done,
then "processConArgs" would not need the
statement:

=========================================
((javax.swing.JFrame java.lang.String)
(.setTitle c a))
=========================================

As an aside, I think it would be nice to have
the inner local function "(processConArg c a)"
in the global function "(processConArgs c as)"
made global also. Hence, (processConArgs c as)
would of course be shorten to invoke
(processConArgs c as).

I wish this since I sometimes (almost always)
like to build up my components like the following:

(define f (window))
(define b (button "OK"))
(writestring f "My Main Window")
(processConArg f b)
etc.

I am not 100% sure about this.
But, I think it might be useful
to pull out "processConArg".

Thanks for the fixes. We've made the changes.

There are a bunch more Swing changes that need to be added, but
I first have to fix a bug which causes the Scheme->Java compiler
to improperly handle inner classes....

I'll look at the issue of pulling processConArg out when I
add the
next batch of Swing extensions... for now you can use
(processConArgs f (list b))
