Question
Here is my current settings:
private JComponent upperContent = new GeneralContent();
private JComponent lowerContent = new GeneralContent();
// GeneralContent extends JComponent
jframe.setLayout(new GridLayout(2, 0));
upperContent.setLayout(null);
lowerContent.setLayout(new GridBagLayout());
jframe.add(upperContent);
jframe.add(lowerContent)
lowerContent's all component are displayed as expected while upperContent didn't display the component that i was added to it by using the following code:
JLabel label=new JLabel();
upperContent.add(label);
label.setLocation(15,15);
i also used label.repaint(); & upperContent.revalidate() neither worked
Solution
You get absolute positioning with a null layout. The bad news is that everything is totally up to you from then on.
