selectAll() in JTable field

Hi !

Just wanted to know how to select the entire field of a JTable when the user single clicks the field.

I've started to write a mouse listener but got stuck :

table.addMouseListener(new MouseListener() {
public void mouseClicked(MouseEvent e){

}
public void mouseEntered(MouseEvent e){

}
public void mouseExited(MouseEvent e){

}
public void mousePressed(MouseEvent e){

}
public void mouseReleased(MouseEvent e){
if(table.isCellEditable(table.getSelectedRow(),table.getSelectedColumn())){
//What now?
}
}

}
);

Can I do it like this? If not, how can I do it then?

I don't know if it is important but the field holds a float value and I need to keep the validation.

So, you have to tell your table cell editor that it has to become active at one click (which is default 2, I believe)

Your solution, with a minor alteration, solved one of my problems:
((DefaultCellEditor)yourTable.getDefaultEditor(Float.class)).setClickCountToStart(1);
If I used getCellEditor() it would return null

Now I only need to selectAll() when the field is clicked
