JTable

[Anonymous]

is there a way i could set/fix the column widths for a Jtable when it displays....
is there anyway to make it uneditable....

[Alan Shore]

I found the easiest way to make a JTable non-editable is to extend the DefaultTableModel like this:
<CODE>
package util;
import javax.swing.*;
import javax.swing.table.*;
// No edit table model
public class NoEditTableModel extends DefaultTableModel
{
public NoEditTableModel(java.lang.Object[] colNames, int numRows)
{
super(colNames, numRows);
}
public NoEditTableModel(java.util.Vector data, java.util.Vector columnNames)
{
super(data, columnNames);
}
public NoEditTableModel(Object[][] data, Object[] columnNames) {
super(data, columnNames);
}
public boolean isCellEditable(int row, int col)
{
return false;
}
}
</CODE>
*****
To set column sizes, set them in the TableColumnModel:
<CODE>
TableColumnModel colModel = yourTbl.getColumnModel();
// set width of columns in table
colModel.getColumn(0).setPreferredWidth(100);
colModel.getColumn(1).setPreferredWidth(100);
colModel.getColumn(2).setPreferredWidth(150);
colModel.getColumn(3).setPreferredWidth(100);
colModel.getColumn(4).setPreferredWidth(175);
colModel.getColumn(5).setPreferredWidth(200);
</CODE>
Hope this will help!

I tried this but I keep getting an ArrayIndexOutOfBoundsException
Any idea why?

Okay I like the example listed above two points,
1. can we default the text font size
2. can we set the Column class at this same place?
-- and also set the ColumnName?
I know we can create the getColumnName getColumnClass methods... it would seem more strightforward to just set them here....
Thanks!
