Create implementation for native accessibility peer for Statusbar java role. I
do not see any Swing component with StatusBar accessibility role, so I have
created a component with the StatusBar role to test this. I have tested the
implementation with the following example and a few more similar examples. I do
not see any difference in Voice Over output.
`
import javax.accessibility.Accessible;
import javax.accessibility.AccessibleContext;
import javax.accessibility.AccessibleRole;
import javax.accessibility.AccessibleStateSet;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class StatusBarDemo {
public static void main(String[] args) throws Exception {
StatusBarDemo demo = new StatusBarDemo();
SwingUtilities.invokeAndWait(demo::createAndShowGUI);
}
void createAndShowGUI() {
JFrame jframe = new JFrame("StatusBar Demo");
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jframe.setLayout(new BorderLayout());
jframe.setSize(200, 200);
// create the status bar panel and shove it down the bottom of the
frame
JPanel statusPanel = new StatusBar();
statusPanel.setBorder(new BevelBorder(BevelBorder.LOWERED));
statusPanel.setPreferredSize(new Dimension(jframe.getWidth(), 16));
statusPanel.setLayout(new BorderLayout());
JLabel date = new JLabel();
date.setOpaque(true);
date.setBackground(Color.black);
date.setForeground(Color.WHITE);
statusPanel.setLayout(new BorderLayout());
statusPanel.setBackground(Color.LIGHT_GRAY);
statusPanel.add(date, BorderLayout.CENTER);
Timer timer = new javax.swing.Timer(1000, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
java.util.Date now = new java.util.Date();
String ss = DateFormat.getDateTimeInstance().format(now);
date.setText(ss);
date.setToolTipText("Welcome, Today is " + ss);
}
});
timer.start();
jframe.add(statusPanel, BorderLayout.SOUTH);
jframe.setLocationRelativeTo(null);
jframe.setVisible(true);
}
class StatusBar extends JPanel implements Accessible {
AccessibleContext accessibleContext;
public AccessibleContext getAccessibleContext() {
if (accessibleContext == null) {
accessibleContext = new StatusBar.AccessibleJStatusBar();
}
return accessibleContext;
}
protected class AccessibleJStatusBar extends AccessibleJComponent {
public AccessibleStateSet getAccessibleStateSet() {
AccessibleStateSet states = super.getAccessibleStateSet();
return states;
}
public AccessibleRole getAccessibleRole() {
return AccessibleRole.STATUS_BAR;
}
}
}
