setFocus in JOptionPane :)
Hey!
I have a JOptionPane that shows a list of items with JList.
I'd like a user to be able to hit the arrow keys to move up/down the list, but the OK button steals focus!
I naturally can't set focus to the JList after the dialog is open... what can I do?
The following is my code, but OK still takes focus:
privatestaticfinalint PLN_MSG = JOptionPane.PLAIN_MESSAGE;
publicstatic Object showListDialog(Component parent, java.util.List<?> o){
JDialog dialog;
final JList list =new JList(o.toArray());
Object[] msg ={"Select an item" +":",new JScrollPane(list)};
final JOptionPane op =new JOptionPane(msg, PLN_MSG, JOptionPane.OK_CANCEL_OPTION,null);
dialog = op.createDialog(parent, (String)msg[0]);
list.setSelectedIndex(0);
list.setCellRenderer(new ListRenderer());
list.addMouseListener(new MouseAdapter(){
publicvoid mouseClicked(MouseEvent e){
if(e.getButton() == MouseEvent.BUTTON1 && e.getClickCount() == 2){
op.setValue(JOptionPane.OK_OPTION);
SwingUtilities.getWindowAncestor(e.getComponent()).setVisible(false);
}
}
});
/** WORKS!!! ADDED CODE */
dialog.addWindowListener(new WindowAdapter(){
publicvoid windowOpened(WindowEvent e){
list.requestFocusInWindow();
}
});
/** WORKS!!! ADDED CODE */
// list.requestFocus(); // Doesn't work here :(
dialog.setVisible(true);
// list.requestFocus(); // Doesn't work here :(
if (((Integer)op.getValue()).equals(JOptionPane.OK_OPTION))
return list.getSelectedValue();
returnnull;
}
Thanks!!!
