The SSCE above creates a JTable with JButton as cell renderer/editor.
It's working fine & button action is triggered correclty
When trying to add a popup menu to the JButton, the menu is not shown when clicking mouse right button.
Looks like the table is consuming the Mouse right click event, so the JButton didn't receive & react to the event ?
Any clue ?
Thanks in advance for any guidance/help

Now it's working with the following code. Hope this may help some one else.

How to set Key Binding to editable JTable in swing?

I want to remove selected row of JTable by pressing only Delete button.
When I press Delete, selected cell becomes editable and my action(on jframe) does not receive KeyEvent.
Please, run this demo to see the effect:
public class TestTableKeyBinding extends JFrame {
// private static final int MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask();
private JTable table;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
TestTableKeyBinding test = new TestTableKeyBinding();
test.setVisible(true);
}
});
}
TestTableKeyBinding() {
super();
initUI();
addKeyBindings();
}
private void initUI() {
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
String[] headers = new String[] { "apples", "bananas" };
String[][] data = new String[][] { { "1", "2" }, { "4", "6" }, { "5", "7" }, { "1", "3" }, { "2", "11" } };
table = new JTable(data, headers);
table.setRowSelectionAllowed(true);
this.add(new JScrollPane(table));
this.pack();
this.setSize(new Dimension(300, 400));
}
private void addKeyBindings() {
// root maps
InputMap im = this.getRootPane().getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
ActionMap am = this.getRootPane().getActionMap();
// add custom action
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_DELETE, 0), "save");
am.put("save", saveAction());
}
private AbstractAction saveAction() {
AbstractAction save = new AbstractAction() {
#Override
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(TestTableKeyBinding.this.table, "Action Triggered.");
table.editingCanceled(null);
table.editingStopped(null);
int selectedRow = table.getSelectedRow();
if (selectedRow != -1) {
((DefaultTableModel) table.getModel()).removeRow(selectedRow);
}
}
};
return save;
}
}
Thanks for help!

I have tested your code and made some changes as mentioned below. Now it's working fine.
private void addKeyBindings() {
KeyStroke keyStroke = KeyStroke.getKeyStroke(KeyEvent.VK_DELETE, 0);
table.getActionMap().put("save", saveAction());
table.getInputMap(JComponent.WHEN_FOCUSED).put(keyStroke, "save");
}
Make one more change as mentioned below
table = new JTable(new DefaultTableModel(data,headers));
otherwise it will result in ClassCastException at below line
((DefaultTableModel) table.getModel()).removeRow(selectedRow);
Here is complete code:

How do I make it possible to select text in a JTable cell with editing disabled?

Imagine I'm building an IRC client with Java and I'd like rich text in the chat view to show IRC colors and colored nicks. I'd like to build this with a JTable. I can do that, but the text is then not selectable. Making the table editable doesn't make sense.
I've also investigated:
TextArea - no rich text formatting
JEditPane - can't append, only replace which is bad performance wise
JList - can't select text
So I got a table working I just need the text to be selectable without making it editable. I'd also would only like the text contents, and none of the HTML to be copied into the clipboard upon copying the text selection.
I have tried various iterations of setRowSelectionAllowed(), setColumnSelectionEnabled() and setCellSelectionEnabled() and setSelectionMode the table model returns false for isCellEditable(). Nothing has made the text selectable.
EDIT: as per answer 1 I was wrong about text editor panes so I'm trying those solutions.

I don't know why you don't want to use a JTextPane or JEditorPane. You insert text by its document. Examples here --> How to use Editor Panes and Text Panes.
But for your purpose you can for example do something like this. I override changeSelection to selectAll text when is clicking, the cells are editable but its cellEditors are not editable.
public class JTableTest {
private final DefaultCellEditor cellEditor;
private final JTextField textfield;
private JPanel panel;
private MyTableModel tableModel = new MyTableModel();

#Override

}

final int row, final int column, final boolean toggle, final boolean extend) {
super.changeSelection(row, column, toggle, extend);
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
if ((getCellEditor(row, column) != null && !editCellAt(row, column))) {
JTextField textfield=(JTextField)JTableTest.this.cellEditor.getComponent();
textfield.selectAll();
}
}
});
}
};
public JTableTest() {
JScrollPane scroll = new JScrollPane(table);
table.setModel(tableModel);
panel = new JPanel(new BorderLayout());
panel.add(scroll, BorderLayout.CENTER);
textfield = new JTextField();
textfield.setEditable(Boolean.FALSE);
textfield.setBorder(null);
cellEditor = new DefaultCellEditor(textfield);
tableModel.insertValue(new ItemRow("nonEditable", "Editable"));
}
private class ItemRow {
private String column1;

this.column1 = column1;
this.column2 = column2;

}
#Override

fireTableCellUpdated(inRow, inCol);

I accomplished this by enabling the editing and then making the component responsible for the edition ignore any changes. For this I created a TableCellEditor and intercepted the key types to the JTextField, the component used for editing.

I tried both the answers here... but one problem at least is that you can tell when you've entered the "editing" mode.
This might be of interest... uses a combination of Editor magic and cheeky rendering to make it look like no editing is going on: editor's click-count-to-start is set to 1, and the component (JTextPane) delivered by the editor's method does setEditable( false ).
If this tickles your fancy, you might be interested at looking at my implementation of a JTable which adjusts (perfectly, harnessing the JTextPane's powerful wrapping power) the row height to the text, for individual rows, including when you change the columns: How to wrap lines in a jtable cell?

Maybe you can implement your own TableCellRenderer that extends JTextField in your table.

How do I create a JTable with editable headers?

Disable JComboBox inside JTable on click of JCheckBox

I have JTable and it has a JCheckBox and a JComoboBox in two different columns. When I select a JCheckBox that corresponds to that row, the JComboBox should be disable. Kindly help me.

Simply disable editing of the cell based on your model. In your TableModel, override/implement the isCellEditable() method to return the "value" of the checkbox.
Although the following example is not based on JComboBox, it illustrates how to disable edition of a cell based on the value of a checkbox at the beginning of the row:

for (int i = 0; i < 3; i++) {
setValueAt(Boolean.TRUE, i, 0);
setValueAt(Double.valueOf(i), i, 1);
}
}
#Override
public boolean isCellEditable(int row, int column) {
if (column == 1) {
return (Boolean) getValueAt(row, 0);
}
return super.isCellEditable(row, column);
}
#Override
public Class<?> getColumnClass(int columnIndex) {
if (columnIndex == 0) {
return Boolean.class;
} else if (columnIndex == 1) {
return Double.class;
}
return super.getColumnClass(columnIndex);
}
}
