but i think i have problems when trying to sort data by clicking at the column header.
this is the error exception:
java.lang.ClassCastException: models.HighlightModel cannot be cast to javax.swing.table.DefaultTableModel

which makes sense, since i derived my model from AbstractTableModel, but your table expects the model to be DefaultTableModel.

i hope the table will sometime support model which is derived from AbstractTableModel, maybe by simply disabling the sort, or even better by letting the programmer define their own sort function.

but this is a very beautiful table indeed!

the following execption has been thrown during painting of the form. Use Inspector to fix or remove the problem.
java.lang.NullPointException
at.ui.jtunestabe.JTunesTableCellRenderer.getTableCellRendererComponent(Unknown Source)
at javax.swing.JTable.preperRenderer(JTable.java:5683)

can someone help me out…

And run the .jar and I can see the example, but I having a problem to use it on my work. I’m working with eclipse ide in a swing application.

Could someone please tell me how to use it ???

Works:

JTunesTable table = new JTunesTable(model);

Doesn’t work:

JTunesTable table = new JTunesTable();
table.setModel(model);

I think the problem with the latter is that AutoCreateColumnsFromModel is set to false, and that’s set to false because createColumnsFromModel resets style. So my gut feeling is that to fix this issue will require overriding createColumnsFromModel with code that doesn’t reset rendering. I’ve given that a stab, but so far it’s not working.

I am, however, having some trouble making it work with the TableExample.java example that comes with Apple Developer Toolkit:

/Developer/Examples/Java/JFC/TableExample/TableExample.java

Has anyone successfully gotten JTunesTable to work with this example? For me, nothing shows up.

Replace the last 4 lines with:

———————————————————————
}
setBackground(new Color(100, 100, 100, 0));
}
super.paintComponent(g);
}
———————————————————————

However, I have some tips to how the performance can be improved. Compared to a regular JTable it is in its current form about 3-5 times as slow. Here are the tricks I found that make a huge difference:

- Make JTunesTableCellRenderer and JTunesHeaderRenderer extend DefaultTableCellRenderer instead of JLabel (makes some unnecessary methods noop)

- The paintComponent(Graphics g) in JTunesTableCellRenderer seems to work better when changed to:

———————————————————————————–
public void paintComponent(Graphics g) {
if (systemColor) {
if (selected) {
setForeground(systemHighlightTextColor);
setBackground(systemHighlightColor);
}
super.paint(g);
return;

} else {
if (selected) {
Graphics2D g2 = (Graphics2D) g;
g2.setPaint(getGradientPaint());
Rectangle2D drawRect = new Rectangle2D.Double(0, 0, getWidth(), getHeight());
g2.fill(drawRect);
} else {
Color bgColor = getBackground();
g.setColor(bgColor);
g.fillRect(0, 0, getWidth(), getHeight());
setForeground(selectedColor);
}
}
super.paintComponent(g);
}
———————————————————————————–

Although I am not sure the paintComponent trick will work on all platforms? If you have any other ways to improve performance I would be very grateful!
