JComboBox in JTable and Cant get Focus...

[markw8500]

I put an editable combo box in a Jtable and I can not transfer the focus to the combo box... I also overroad my combobox because I need to filter the input... I have searched for hours and cant find any solution...

Here is my code:

package jtablecombobox;

import comboBoxes.JTableComboBox;
import comboBoxes.RowEditorModel;
import java.awt.BorderLayout;
import java.awt.Component;
import javax.swing.AbstractCellEditor;
import javax.swing.JComboBox;

public class DisplayPanel extends JPanel {

    private String schema;
    private JTable jt;
    private DefaultTableModel myModel;
    private JTableComboBox jtcb;

    public DisplayPanel() {
        String[] items = new String[]{"", "1.85", "1.50", "1.35"};
        jtcb = new JTableComboBox(items, 2, 10);

        initComponents();

    }

    private void initComponents() {

        myModel = new DefaultTableModel();
        myModel.setColumnCount(3);
        myModel.setRowCount(10);

        jt = new JTable(myModel);

        //RowEditorModel rm = new RowEditorModel();

        //jt.setRowEditorModel(rm);
        //rm.addEditorForRow(0);
        //rm.addEditorForRow(1);
        //jt.setRowEditorModel(new RowEditorModel(2));

        //jt.setR


        TableColumn column = jt.getColumnModel().getColumn(2);

        String[] values = new String[]{"", "1.85", "1.50", "1.35"};
        column.setCellEditor(new MyComboBoxEditor(values));
        column.setCellRenderer(new MyComboBoxRenderer(values));
        //column.setCellRenderer(new DataFieldRenderer());

        JPanel jp = new JPanel(new BorderLayout());


        jp.add(jt, BorderLayout.CENTER);

        this.add(jp, BorderLayout.CENTER);


    }


    public class MyComboBoxRenderer extends JComboBox implements TableCellRenderer {

        JComponent component = new JTextField();
        private JTableComboBox cb;

        public MyComboBoxRenderer(String[] items) {

            //super(items);

            cb = new JTableComboBox(items, 2, 10);
        }

        public Component getTableCellRendererComponent(JTable table, Object value,
                boolean isSelected, boolean hasFocus, int row, int column) {
            if (isSelected) {

                jtcb.setForeground(table.getSelectionForeground());
                jtcb.setBackground(table.getSelectionBackground());
            } else {
                jtcb.setForeground(table.getForeground());

            }

            ///jtcb.getMyDF().setSetText(true);

                return cb.getEditor().getEditorComponent().getAccessibleContext().getAccessibleEditableText().getTextRange(0, cb.getEditor().getEditorComponent().getAccessibleContext().getAccessibleEditableText().getCharCount());
            }




            return cb.getSelectedItem();
        //throw new UnsupportedOperationException("Not supported yet.");
        }

        public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {


            cb.requestFocusInWindow();

            cb.getMyDF().clearDocument();
            cb.setSelectedIndex(0);
            cb.setText(false);
            return cb;
        //throw new UnsupportedOperationException("Not supported yet.");
        }
    }

    public void forceFocus() {

        SwingUtilities.invokeLater(new Runnable() {

            public void run() {

                jt.add(jtcb);


                jt.transferFocus();
                jtcb.requestFocus();
                jtcb.getEditor().getEditorComponent().requestFocus();
            //jt.revalidate();
            //jt.repaint();

            }
        });



    }
}

Any help is appreciated...

Never Mind... I finally figured it out... Here is the solution:

public class MyComboBoxRenderer extends JComboBox implements TableCellRenderer {

        JComponent component = new JTextField();
        private JTableComboBox cb;

        public MyComboBoxRenderer(String[] items) {

            //super(items);

            cb = new JTableComboBox(items, 2, 10);
        }

        public Component getTableCellRendererComponent(JTable table, Object value,
                boolean isSelected, boolean hasFocus, int row, int column) {
            if (isSelected) {

                jtcb.setForeground(table.getSelectionForeground());
                jtcb.setBackground(table.getSelectionBackground());
            } else {
                jtcb.setForeground(table.getForeground());
                jtcb.setBackground(table.getBackground());
            }



            if (hasFocus && column==2) {
[B]
                jt.editCellAt(jt.getSelectedRow(), 2);
                Component myEditor = jt.getEditorComponent();

                myEditor.requestFocus();
[/B]

            }

            jtcb.setSelectedItem(value);



            return jtcb;
        }
    }

From everything I have read, you must first put the cell into editing mode by "JTable.editValueAt(row, col)", then get the editor component and request focus... So the key code is:

                jt.editCellAt(jt.getSelectedRow(), columnOfComboBox);
                Component myEditor = jt.getEditorComponent();

                myEditor.requestFocus();
