What is the difference between a panel and a pane? They are both used often, but why is it JTabbedPane and JPanel and not the other wayaround? Any reason?...
Why do you sometimes use .add (eg. JPanel) and sometimes .getContentPane().add (eg. JInternalDialog)?
Is there and way to, by code, maximize a JFrame or JInternalFrame?
JTabbedPane is an actual component. JPanel is a component also but it really offers no additional functionality other then to group components.Quote:

I used to be confused with this also. And i would often forget to add components to the content pane instead of say a JFrame which causes a compilation error.Quote:

.getContentPane().add (eg. JInternalDialog) that you are refering to is a short hand alternative. You can code it like this if you wanted to(as i often do)
Code:JFrame jf = new JFrame("Hello");
Container c = jf.getContentPane();
c.add(jc);
a panel (be it awt or swing) is a container, as was said before. a pane is part of the view port (sort of like the z axis/order). go to http://java.sun.com/docs/books/tutorial/search.html and type in pane - it should bring up quite a bit about panes
I thought we resolved this issue. :p
mainly just put it there for any other newbie who may be a tad confused bout it, sowy :D
must admit, it is a bit hard to grasp the concept of java at times (especially if one has programmed in another language e.g vb - went through that hell myself: cobol, basic, vb, pascal)
