JTextField selectAll() And DefaultCellEditor

Posted by tech on October 20, 2009

I am guessing this is quite a common problem that programmers encounter when they have JTextField objects inside a JTable. When you click on a cell, it would not select all the text in it. You have to double click it first. Even the DefaultCellEditor’s setClickCountToStart(1) method does not help. The workaround for this is to override the shouldSelectCell() method.

@Override
public boolean shouldSelectCell(EventObject eo) {
    ((JTextField) getComponent()).selectAll();
    return super.shouldSelectCell(eo);
}
