asked on

getContentPane() ...

Hi Experts,

I am reading the JFrame in the Sun java tutorial. I saw JFrame has the following function :

getContentPane() : Returns the contentPane object for this frame.

I don't know what "contentPane" is ... and I can not find the "contentPane" class or container it in the tutorial ....... could anyone please give me some directions ? Thanks a lot !

contentpane is the container that you add components to.
it is a Container.

Mick Barry

ie. you don't add components to the frame, you instead add them to the content pane.

eg.

Container pane = frame.getContentPane();
pane.setLayout(new FlowLayout());
pane.add(new JLabel("X"));

Thanks .... so is it true that : in the

"pane.setLayout(new FlowLayout());
pane.add(new JLabel("X")); "

we still use JFrame method setLayout() and add(), even though they are invoked by a pane rather than a frame ?

thanks !
