Bring JPanel To Front Of Other Objects In Java (SWING)


Answer :

So here you have at least two solutions. Either go with what @Geoff and @sthupahsmaht are suggesting. BTW also possible is to use JOptionPane which automatically creates a dialog for you.

The other option would be to use a GlassPane from a frame.

Or yet another option is to use JLayeredPane as @jzd suggests.

EDIT: Example showing how to use GlassPane to capture user selections. Try following steps:

1.Left clicking on the glass pane visible at start. See the output.

2.Right click it. This hides the glass pane.

3.Left clicking on the content pane. See the output.

4.Right click it. Go to point 1. Enjoy.

import java.awt.Color; import java.awt.Dimension; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.SwingUtilities;  public class OverPanel extends JPanel {        private static void createAndShowGUI()     {         final JFrame f = new JFrame();         f.setPreferredSize(new Dimension(400, 300));         f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);                JPanel glassPanel = new JPanel();         glassPanel.setBackground(Color.RED);                 glassPanel.addMouseListener(new MouseAdapter()         {             @Override             public void mousePressed(MouseEvent e)             {                 super.mousePressed(e);                 System.out.println("f.getGlassPane() mousePressed");                 if(e.getButton() == MouseEvent.BUTTON3)                     f.getGlassPane().setVisible(false);             }         });         f.setGlassPane(glassPanel);               f.getContentPane().setBackground(Color.GREEN);         f.getContentPane().addMouseListener(new MouseAdapter()         {             @Override             public void mousePressed(MouseEvent e)             {                 super.mousePressed(e);                 System.out.println("f.getContentPane() mousePressed");                 if(e.getButton() == MouseEvent.BUTTON3)                     f.getGlassPane().setVisible(true);             }         });         f.getGlassPane().setVisible(true);         f.pack();         f.setVisible(true);     }      public static void main(String[] args)     {         SwingUtilities.invokeLater(new Runnable()         {             @Override             public void run()             {                 createAndShowGUI();             }         });     } }

EDIT2: If you want to have an effect of a dialog, you can achieve it by incorporating appropriately this code into my example.

        JPanel panel = new JPanel(new GridLayout(0, 1));         panel.setBorder(BorderFactory.createLineBorder(Color.BLACK, 2));         panel.setBackground(Color.YELLOW);         panel.add(new JLabel("I am message Label"));         panel.add(new JButton("CLOSE"));         JPanel glassPanel = new JPanel(new GridBagLayout());         glassPanel.setOpaque(false);         glassPanel.add(panel);

You need a to use a JLayeredPane for moving components in front of each other.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
