An example of adding code to a cell renderer is in TableDialogEditDemo. For example, the following code makes the first cell in the first column of the table use a custom renderer:. When the user explicitly resizes columns, the columns’ preferred widths are set coure that the user-specified sizes become the columns’ new current widths.
As you can see, the code is pretty simple. You can set a type-specific cell renderer using the JTable method setDefaultRenderer.

The AbstractCellEditor class is a good superclass to use. Basically, it creates a subclass of JTableHeader that overrides the getToolTipText MouseEvent method so that it returns the text for the current column.
However, sometimes it can be simpler to specify tool tip text by overriding JTable ‘s implementation of the getToolTipText MouseEvent method. Before you go on to the next few tasks, you need to understand how tables draw their cells. TableCellRenderer requires just one method: Email Required, but never shown. Demonstrates sorting and filtering, and how this can cause the view coordinates to diverge from the model coordinates.
JTable (Java Platform SE 6 b18)
To specify the sort order and sort precedence for columns, invoke setSortKeys. Shows how to use all list selection modes, using a list selection listener that’s shared between a table and list.
The following code makes the formatted text field the editor for all columns that contain data of type Integer. In the screenshot below, a user has run the program, clicked in the first row, then control-clicked in the third row. The following screen shot shows TableFilterDemo before any sorting or filtering has been done. Click cougs cell that contains “Snowboarding”. The table in SimpleTableDemo.
The entire first row is selected, indicating that you have selected Kathy Smith’s data. If DefaultTableModel is not a suitable base class for your custom table model class, consider subclassing AbstractTableModel. TableModel; public class SimpleTableDemo Setting both rowSelectionEnabled and columnSelectionEnabled to a value has the side effect of also setting cellSelectionEnabled to that value.
A table model object must implement the TableModel interface. In this case, the second column has the first sort key, so they rows are sorted by first name, then last name. Click the cell that contains “Snowboarding”.
How to Use Various Components. There jtbale also a text pane jtahle logs selection events. If ocurs click on the “Single Interval Selection” radio button, you can select a set of rows that must be contiguous. This is known as filtering. PrinterExceptionwhich is a checked exception ; that’s why the above example uses a htable This provides a table that does a simple locale-specific sort when the user clicks on a column header. If extending DefaultTableCellRenderer is insufficient, you can build a renderer using another superclass.
The override of getTableCellEditorComponent sets the formatted text field’s value property and not just the text property it inherits from JTextField before the editor is shown.

Setting rowSelectionEnabled and columnSelectionEnabled to different values has the side effect of also setting cellSelectionEnabled to false. If the text isn’t valid, your implementation of stopCellEditing puts up a dialog that gives the user the option of continuing to edit or reverting to the last good value.
The bold line of code sets up the combo box as the editor for a specific column. You can set a type-specific cell renderer using the JTable method setDefaultRenderer. To specify that cells in a particular column should use a renderer, you use the TableColumn method setCellRenderer.
To specify more precise column types, the table model must define the getColumnClass method appropriately, as demonstrated by TableDemo. See below the code taken from TableDemo. A basic table with no custom model.
This action defines a row sorter that is an instance of javax.
How to Use Tables
If the programmer does not provide a table model object, JTable automatically creates an instance of DefaultTableModel. When using a sorter, always remember to translate cell coordinates. You can even specify a cell-specific renderer by creating a JTable subclass. If DefaultTableModel is not a ccours base class for your custom table model class, consider subclassing AbstractTableModel.
The easiest way is to create jtablw subclass of an existing component, making your subclass implement the TableCellRenderer interface.
As DefaultCellEditor does not support other types of components, you must do a little more work.
