JXTreeTable with checkbox

I need to have checkbox column in JXTreeTable. I google and found that the solution is quite troublesome (the solutions were dated a few years ago).

So I tried to check JXTreeTableVisualCheck class. I found that its interactiveEditWithComboBox() show a convenient use of DefaultCellEditor(…).

After some testing, I found that in latest version of SwingX, checkbox in JXTreeTable can be done with relatively little effort.

	
        TableColumn selCol = treeTable.getColumnModel().getColumn(4);
        JCheckBox cb = new JCheckBox();
        cb.setHorizontalAlignment(SwingConstants.CENTER); // without this, checkbox move to left during click
        selCol.setCellEditor(new DefaultCellEditor(cb));

As I found out later, JXTreeTable has built-in support for checkbox. Just need to return Boolean.class in public Class<?> getColumnClass(int column) method. There is no need to explicitly set cell editor as shown above for boolean value.

JXTreeTablePanel.java is a simple example for editable checkbox in JXTreeTable.
