JTable not showing data

[Krit Christoforou]

Hello all,
I'm trying to create a Jtable and make it load the contents of a vector after i press a button.
The problem is that the table wont display what it should, instead it remains empty.
I know that my vector is loaded because i print out its contents in the command line.

Here is some code, i hope that helps.
Thanks

     
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
javax.swing.JScrollPane scroller;
final String[] heading ={"column 1","column 2",
"column 3","column 4"};
java.util.Vector heads = new java.util.Vector();
for (int i=0; i<heading.length; i++)
heads.addElement(heading[i]);
java.util.Vector newVect;
newVect = new java.util.Vector(resultsBean.getVectorData());
jTable1 = new javax.swing.JTable(newVect,heads);
scroller = new javax.swing.JScrollPane(jTable1);
getContentPane().add(scroller);
System.out.println(newVect);
    }

From the JavaDocs for the JTable(Vector rowData, Vector columnNames) constructor:

Constructs a JTable to display the values in the Vector of Vectors, rowData, with column names, columnNames.

Does your data Vector (newVect) hold Vectors of Strings, or just Strings directly?

Hello again david
always helpful hehe

The vector holds vectors of strings.
i changed some things in the code and got it to work. I cant get it to work with a scrollpane tho.
Here is my code:

     private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
//javax.swing.JScrollPane scroller = new javax.swing.JScrollPane(jTable1);
//getContentPane().add(scroller);
final String[] heading = {"Account No.","Surname",
 "First Names","Balance"};
java.util.Vector heads = new java.util.Vector();
for (int i=0; i<heading.length; i++)
heads.addElement(heading[i]);
java.util.Vector seasonRes;
seasonRes = new java.util.Vector(resultsBean.getSeasonResults());
jTable1.setModel(new javax.swing.table.DefaultTableModel(seasonRes,heads)); 
jTable1.repaint();
    }
 

The strange thing is that if i uncomment the scrollpane lines, the table remains empty, i cant get it to load the vector.
