How to set Palette Layer for JDesktopPane in Java?
At first, create a JDesktopPane −
JDesktopPane desktopPane = new JDesktopPane();
Now, create an Internal Frame −
JInternalFrame intFrame = new JInternalFrame("Our Frame", true, true, true, true); intFrame.setBounds(50, 90, 200, 250);
Set Pallette layer for JDesktopPane and add the Internal Frame to JDesktopPane −
intFrame.putClientProperty("JInternalFrame.isPalette", Boolean.TRUE); desktopPane.add(intFrame,JDesktopPane.PALETTE_LAYER);
The following is an example to set palette layer for JDesktopPane −
package my; import java.awt.BorderLayout; import javax.swing.JButton; import javax.swing.JDesktopPane; import javax.swing.JFrame; import javax.swing.JInternalFrame; import javax.swing.JLabel; public class SwingDemo { public static void main(final String[] args) { JFrame frame = new JFrame("Demo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JDesktopPane desktopPane = new JDesktopPane(); JInternalFrame intFrame = new JInternalFrame("Our Frame", true, true, true, true); intFrame.setBounds(50, 90, 200, 250); intFrame.putClientProperty("JInternalFrame.isPalette", Boolean.TRUE); desktopPane.add(intFrame,JDesktopPane.PALETTE_LAYER); JLabel label = new JLabel(intFrame.getTitle(), JLabel.CENTER); JButton button = new JButton("Demo Button"); intFrame.add(label, BorderLayout.CENTER); intFrame.add(button, BorderLayout.WEST); intFrame.setVisible(true); frame.add(desktopPane, BorderLayout.CENTER); frame.setSize(600, 500); frame.setVisible(true); } }
