MVC Adding various views to a Main Frame
Hi,
If I have a a couple of different Views which are created by a couple of different controllers what would be the best way of adding these to a main frame.
For example
View1 extends JPanel
View1Controller creates it.
View2 extends JPanel
View2 Controller creates it.
MainFrame extends JFrame
currently I have the controllers returning the View that they create so I can add them like so
getContentPane().add(controller1.getView1());
getContentPane().add(controller2.getView2());
This however does not sit right with me, though I'm not sure why.
Does anybody have any thoughts or insights on the above.
Thanks
Jon

Should you not extend JPanel?
Would I then extend JFrame for each view?
I'm creating the Views from within the controller due to the fact the HeadFirst Design pattern book did.
Though from looking at the current design I could probably easily take them out.

For views, I prefer to use the below. You can either create a
JPanel in the constructor, add components to it, and then add the
JPanel to the Container, or you can add components directly to
the container. This way, your view is container-agnostic -- you can
add it to a dialog, frame, jpanel ...
This is also "more OO", because you're really not adding to what it
means to be a JPanel. What you're doing is the same as
extending DefaultComboBoxModel because you want to add
some Strings.
Okay, I haven't read HFDP, so I can't comment on that. I got sold
on the above way of doing things by some forum regulars a while
ago. I have no experience with using controllers
as factories for the view. Seems to me like that
could be considered a violation of SRP, though.
public class MyView {
public MyView(final Container container) {
container.add();
}
}
...
final JDialog dialog = new JDialog();
final MyView myView = new MyView(dialog.getContentPane());
final JPanel panel = new JPanel();
final MyView myView2 = new MyView(panel);

Thanks very much for your reply.
I'll give that a go and see what I come up with.
I don't know what the going rate for tipping dukes is so I gave you 10 ;-)
Let me know if that's me being either a tight Englishman or a extravagantAmerican :-)
