Yes, I get that. :-)  I am talking about the
in
{
}
and also the
body
{
}
how are these interpreted by the compiler?  They are both part of 
the function, correct?

in is precondition, body is function body, which expects 
precondition to pass.

Sorry it took so long.  Extremely busy, but anyway, this is the 
piece of the code that is causin the problem:

code
override void text(Dstring txt) // setter
in
{
if(txt.length)
assert(!this.image, Button image with text not supported);
}
body
{
super.text = txt;
}

alias Control.text text; // Overload.
/code

I have no idea what these lines do. Any thoughts?  Thanks.

It checks that you don't set both text and image, because the 
button doesn't support it.

Greetings!

I am trying to compile dfl with the latest version of D1.  I am 
stuck in this error:


c:\D\import\dfl\button.d(381): Error: function 
dfl.button.Button.text cannot have
e an in contract when overriden function dfl.control.Control.text 
does not have an in contract


This is the line 381:

override void text(Dstring txt) // setter
in
{
if(txt.length)
assert(!this.image, Button image with text not supported);
}
body
{
super.text = txt;
}

alias Control.text text; // Overload.

Any help would be greatly appreciated.  Thanks.

If it is just that one error, you could always just comment out 
the in contract and recompile.
