Name: gm110360 Date: 03/03/2004 FULL PRODUCT VERSION : J2SE 1.4.2-b28 J2SE 1.5.0 beta ADDITIONAL OS VERSION INFORMATION : Win 2000 A DESCRIPTION OF THE PROBLEM : Add editable JComboBoxes to a JTable. Click on arrow button to display pop up for the combobox. Click on arrow button again to hide the pop up. Move to a different component in the UI. The combo box is still displayed with the arrow button still visible. It should have been removed on a focus lost event. The combo box is correctly removed if you move to a different cell in the table rather than a different widget in the application. STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : Please run the code below: - 1. Click on the drop-down combo-box(under column veggy) 2. Click in "set focus here" textfield. import javax.swing.*; import javax.swing.table.*; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import java.awt.Dimension; public class TableExample3 implements java.awt.event.ActionListener { ExampleTableModel dataModel; final String[] names = {"First Name", "Last Name", "Favorite Color", "Favorite Number", "Veggy"}; Object[][] data = { {"Mark", "Andrews", "Red", new Integer(2), new Boolean(false)}, {"Tom", "Ball", "Blue", new Integer(99), new Boolean(false)}, {"Alan", "Chung", "Green", new Integer(838), new Boolean(false)}, {"Jeff", "Dinkins", "Turquois", new Integer(8), new Boolean(false)}, {"Amy", "Fowler", "Yellow", new Integer(3), new Boolean(false)}, {"Brian", "Gerhold", "Green", new Integer(0), new Boolean(false)}, {"James", "Gosling", "Pink", new Integer(21), new Boolean(false)}, {"David", "Karlton", "Red", new Integer(1), new Boolean(false)}, {"Dave", "Kloba", "Yellow", new Integer(14), new Boolean(false)}, {"Peter", "Korn", "Purple", new Integer(12), new Boolean(false)}, {"Phil", "Milne", "Purple", new Integer(3), new Boolean(false)}, {"Dave", "Moore", "Green", new Integer(88), new Boolean(false)}, {"Hans", "Muller", "Maroon", new Integer(5), new Boolean(false)}, {"Rick", "Levenson", "Blue", new Integer(2), new Boolean(false)}, {"Tim", "Prinzing", "Blue", new Integer(22), new Boolean(false)}, {"Chester", "Rose", "Black", new Integer(0), new Boolean(false)}, {"Ray", "Ryan", "Gray", new Integer(77), new Boolean(false)}, {"Georges", "Saab", "Red", new Integer(4), new Boolean(false)}, {"Willie", "Walker", "Phthalo Blue", new Integer(4), new Boolean(false)}, {"Kathy", "Walrath", "Blue", new Integer(8), new Boolean(false)}, {"Arnaud", "Weber", "Green", new Integer(44), new Boolean(false)} }; public TableExample3() { JFrame frame = new JFrame("Table"); frame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) {System.exit(0);}}); // Create a model of the data. dataModel = new ExampleTableModel(); JComboBox _editor = new JComboBox(); _editor.addItem(new Boolean(false)); _editor.addItem(new Boolean(true)); // Instead of making the table display the data as it would normally with: JTable tableView = new JTable(dataModel); // Add a sorter, by using the following three lines instead of the one above. //TableSorter sorter = new TableSorter(dataModel); //JTable tableView = new JTable(sorter); //sorter.addMouseListenerToHeaderInTable(tableView); tableView.setDefaultEditor(Boolean.class, new DefaultCellEditor(_editor)); JScrollPane scrollpane = new JScrollPane(tableView); scrollpane.setPreferredSize(new Dimension(700, 300)); frame.getContentPane().setLayout(new java.awt.GridBagLayout()); frame.getContentPane().add(scrollpane); JTextField _text = new JTextField("Set focus here"); frame.getContentPane().add(_text); JButton _button = new JButton("Click to remove row"); frame.getContentPane().add(_button); _button.addActionListener(this); frame.pack(); frame.setVisible(true); } public void actionPerformed(java.awt.event.ActionEvent e) { dataModel.removeARow(); } public static void main(String[] args) { new TableExample3(); } class ExampleTableModel extends AbstractTableModel { // These methods always need to be implemented. public int getColumnCount() { return names.length; } public int getRowCount() { return data.length;} public Object getValueAt(int row, int col) {return data[row][col];} // The default implementations of these methods in // AbstractTableModel would work, but we can refine them. public String getColumnName(int column) {return names[column];} public Class getColumnClass(int col) {return getValueAt(0, col).getClass();} public boolean isCellEditable(int row, int col) {return true;} public void setValueAt(Object aValue, int row, int column) { data[row][column] = aValue; } public void removeARow() { // Remove last row from array Object[][] _smaller_data = new Object[data.length - 1][]; System.arraycopy(data, 0, _smaller_data, 0, _smaller_data.length); data = _smaller_data; System.out.println("Rows = " + data.length); System.out.println("Cols = " + data[0].length); fireTableDataChanged(); } }; } REPRODUCIBILITY : This bug can be reproduced always.
