Edited 3 Years Ago by Nick Evan: Fixed formatting

  1. Post your code in CODE tags so we can read it.
  2. frame.getContentPane().add(pane); the getContentPane() hasn't been required since Java 1.5
  3. Never override paint(), override paintComponent instead.
  4. Because your custom JPanel has no components in it Swing doesn't know how big it is, and probably has its size as 0,0 So the scroll pane won't do much. You may do better by setting your panel's size to a suitable value

Thank u very much

but i cant get how to use "frame.getContentPane().add(pane)"

I have jdk 1.6 version.

I was trying but still it is not working ..

It only show me scroll bar on frame but not working

can you pl's run my code...
Thank you...

Edited 5 Years Ago by Pravinrasal: n/a

Sorry, I don't have time to run your code today. What exactly do you mean by "but not working"? Specify what you expected to see and what you actually saw.

Yes i know that but still i didn't see the scroll bar on jframe...

there are three possible issues

- contents Size that you put ot the JScrollPane is lover than JViewPort View

- you nothing put to the JScrollPane

- change XXX_SCROLLBAR_AS_NEEDED to XXX_SCROLLBAR_AS_ALLWAYS

public static void main(String[] args)
{
JFrame frame = new JFrame();
JScrollPane pane=new JScrollPane(new MainDrawCycle(),JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
frame.getContentPane().add(pane);
// new MainDrawCycle(frame);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(900,700);
frame.setVisible(true);


this size i set

Again I post my program but still scroll bar didn't added

after that setpreffred size of frame and in set jpanels prefferder size as parameter

JFrame frame = new JFrame();
		frame.setBackground(Color.darkGray);
		JPanel jp=new Test();
		jp.setPreferredSize(new Dimension(500,500));
		
		JScrollPane pane=new JScrollPane(jp,JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
		pane.setPreferredSize(jp.getPreferredSize());
		frame.add(pane);

Thank u!

Hai All,

i'm reading the data from the Excel and adding the data to the Container ,then 'm adding the frame to that. I'm getting the out put. I need to put Scroll . how can i add the Scrollbar/ ScrollablePane. I tried ,but i'm not able to select the value which in the bounds of the Panel . Please suggest me..

I'm posting the code please look it.
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
int v=ScrollPaneConstants. VERTICAL_SCROLLBAR_AS_NEEDED;
int h=ScrollPaneConstants. HORIZONTAL_SCROLLBAR_AS_NEEDED;
JScrollPane jsp = new JScrollPane(frame,v,h);
cont = (Container) frame.getContentPane().add(jsp);
frame.setSize(800, 500);
cont.setLayout(new GridLayout(0, 1));
cont.add(new JLabel(QUES));
cont.add(OPT1);
cont.add(OPT2);
cont.add(OPT3);
cont.add(OPT4);
cont.add(OPT5);
cont=frame.getContentPane();
frame.add(jsp);

// here cont is Object of the Container and frame is JFrame.

If i'm doing this not able to select the data which is in // frame.setSize(800, 500);// bounds

Thanks for sharing code, It was so simple i was just wandaring how make jframe scrollable.. but its really simple.. :)
