Hello,

i would like to add JLabels to a custom JPanel. But even with the "null layout", JLabel are not drawn at all.

I i remove the line which sets the layout to null, all the JLabels are displayed in "grid" after a resize of the app.

Code to add the JLabel:

                   System.err.println("DEBUG: width = " + drawPanel.getWidth() + ", height = " + drawPanel.getHeight());
                   
                   for (int i = 0; i < jTablePoints.getRowCount(); i++) {
                       int x = drawPanel.getX(i);
                       int y = drawPanel.getY(i);
                       System.err.print("DEBUG: x = " + x + ", y = " + y);
                       String label = jTablePoints.getValueAt(i, sharedData.labelColumn).toString();
                       JLabel jLabel = new JLabel(label);
                       jLabel.setBackground(Color.GREEN);
                       jLabel.setBorder(javax.swing.BorderFactory.createLineBorder(Color.BLACK,1));
                       jLabel.addMouseListener(new JLabel_Listener());
                       jLabel.addMouseMotionListener(new JLabel_Listener());
                       drawPanel.add(jLabel);
                       jLabel.setLocation(x, y);
                       labelSet.add(jLabel);
                       repaint();
                       System.err.println("=> x = " + jLabel.getX() + ", y = " + jLabel.getY());
                   }
=>

DEBUG: width = 588, height = 359
DEBUG: x = 297, y = 157=> x = 297, y = 157
DEBUG: x = 318, y = 179=> x = 318, y = 179
DEBUG: x = 341, y = 155=> x = 341, y = 155

Why nothing is drawn?

Is it possible to let JLabel overlaps between themselves in a null layout?

TIA
