the component does not show

[shruti]

i need to see two components at the same time and embed one on other.the size of the to be placed component has been reduced so that it fits in the centre of other component.But eaxh time i try doing it i do not see the placed component.please help me.is there a problem with the layout managers?

JPanel mainpanel=new JPanel();
	final JPanel main = new JPanel(new BorderLayout());
        final JPanel optionsPanel = new JPanel();
 	cirarc12 c2=new cirarc12();
	c2.setPreferredSize(new java.awt.Dimension(100,100));
	optionsPanel.add(c2,BorderLayout.CENTER);
	main.add(chartPanel, BorderLayout.NORTH);
        //main.add(c2,BorderLayout.CENTER);
     	mainpanel.add(main,BorderLayout.CENTER);
	mainpanel.add(optionsPanel,BorderLayout.CENTER);
	myframe.add(mainpanel);
	myframe.pack();

You probably missed the setVisible method

JPanel mainpanel=new JPanel();
	final JPanel main = new JPanel(new BorderLayout());
        final JPanel optionsPanel = new JPanel();
 	cirarc12 c2=new cirarc12();
	c2.setPreferredSize(new java.awt.Dimension(100,100));
	optionsPanel.add(c2,BorderLayout.CENTER);
	main.add(chartPanel, BorderLayout.NORTH);
        //main.add(c2,BorderLayout.CENTER);
     	mainpanel.add(main,BorderLayout.CENTER);
	mainpanel.add(optionsPanel,BorderLayout.CENTER);
	myframe.add(mainpanel);
	myframe.pack();
        //following line missing in your code
        myframe.setVisible(true);

NO,that is not the problem.It still doesn't show

What's myframe? Can you show the complete code here to see?

[dswastik]

can you paste the complete code?

[shruti]

it is a huge code.it has a lot of file handling elements in it as it takes input from two files.this is the major problem i'm facing that the cirarc12 component does not appear in the middle of the chart.

what might be the problem?

[Eranga]

Interesting, since you write such a long code, didn't notice that error? Seems to me this is not yours' code.

[shruti]

no,that was enitrely written by me.

[Eranga]

no,that was enitrely written by me.

hmmm, anyway, can you post the code segment that the panel initiate and added the component into it. Without knowing what you exactly do, really difficult to comment.
