I thought it was an unwritten rule that you could always keep your hand in the
cookie jar.... When are you coming to Halifax?

Client.New newForm = new client.New(display, shell);
That looks better... That's what happens when you have 10 things on the go at
once.

Hi Jim,
As you know, I'm no programmer in any shape or form, let alone Java, but should
the "new" after "Client.New" be spaced like that? It just looks odd sat there
on it's own. (O.K. I'll crawl back under my
stone.)
Client.New new = client.New(display, shell);
George.

I have a class titled Main, with in that class I create an instance of my class
MainMenu.
The object mainMenu now has a listener method. With in the method are selection
events for each menu option.
Suppose I click on New from the menu.... The mainMenu.getNewItem event is
triggered and loads the class New:
Client.New new = client.New(display, shell);
So lower case new is a instance of upper case class New. ...by creating the
new object a screen gets loaded, etc.
There is no problem and no issues but the compiler spits a warning to the
affect that the variable new is never used locally. I can live with that since
it's only a warning but I thought that there might be a way of not actually
creating the new object and still achieving the same thing?

G'day, scratch head, I'm trying to get my head around your question...
what is the role of newClass in relation to the construction of the GUI?
Cheers.

...is there a means to create an instance of a class with out actually
specifying an object name?
E.G. Class newClass = Class();
I would like not to have newClass created even though it's scope is limited to
the calling method. If I leave it as it is, the compiler will throw a warning
indicating the object newClass is never called locally.
I use the above syntax for loading a gui class which never gets used other than
to create the gui in the first place.
Just wondering.
