Thread: data won't show up in jtable

Hello,

I've got a problem with putting data into a JTable with a defaultTableModel from another class.

Here is some example code

i've got a actionPerformed in class A

public void actionPerformed(ActionEvent e)
{
if(e.getSource()==ok)
{
getDate();

verlofTabel test = new verlofTabel();
Object[] tempRow = new Object[]{"test1", "test2", "test 3", "test 4", "test5"};
test.addRow(tempRow);
this.setVisible(false);

}
}

The Object[] tempRow has to update my DefaultTableModel in class B

public class verlofTabel extends JPanel {

private Object[][] databaseInfo;
private JScrollPane pane;


public Object[][] getDatabaseInfo() {
return databaseInfo;
}

public void setDatabaseInfo(Object[][] databaseInfo) {
this.databaseInfo = databaseInfo;
}

private String[] columns = {"Begin datum", "Eind datum", "Uren berekend", "Werkelijke uren", "Opmerkingen"};
private MyTableModel dTable = new MyTableModel(databaseInfo, columns);

public verlofTabel()
{

JTable tabelVerlof = new JTable(dTable);

this.add(new JScrollPane(tabelVerlof));

}

public void addRow(Object[] row)
{

dTable.addRow(row);
System.out.println("row added");

}


}

I hope this will help.

You must use Vectors

You must understand that coding is unique but one result is achieved at the end. DO NOT say incorrect for what u never tested.
That's what i normally use genius...

Whatever... you are a moderator..huh? act like one!
