This method signature is very similar to the
getListCellRendererComponent() method used to create custom list
cell renderers.
This method is passed with a JTable, the value associated with
the cell, information regarding whether the value is selected and
whether the cell has the focus, and the row and column indices of
the value. The component returned from the method is painted on
the cell in the table. The class in Listing 40.9,
MyImageCellRenderer, defines a renderer for displaying image
icons in a panel.
Listing 40.9 MyImageCellRenderer.java
import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
public class MyImageCellRenderer extends DefaultTableCellRenderer {
/** Override this method in DefaultTableCellRenderer */
public Component getTableCellRendererComponent
(JTable table, Object value, boolean isSelected,
boolean isFocused, int row, int column) {
Image image = ((ImageIcon)value).getImage();
ImageViewer imageViewer = new ImageViewer(image);
}
}
return imageViewer;
You can also create a custom editor. JTable provides the
DefaultCellEditor class, which can be used to edit a cell in a
text field, a check box, or a combo box. To use it, simply create
a text field, a check box, or a combo box, and pass it to
DefaultCellEditor's constructor to create an editor.
Using a custom renderer and editor, the preceding example can be
revised to display scaled images and to use a custom combo editor
to edit the cells in the Publisher column, as shown in Figure
40.16. The program is given in Listing 40.10.
Figure 40.16
A custom renderer displays a scaled image, and a custom editor
edits the Publisher column using a combo box.
