segue o codigo:
pressF1 = new AbstractAction("F1"){
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, "Dinheiro");
}
};
int cond = JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT;
KeyStroke f1 = KeyStroke.getKeyStroke(KeyEvent.VK_F1,0);
//GUARDA O ROOTPANE
JRootPane rootPane = getRootPane();
//F1
rootPane.getInputMap(cond).put(f1, "F1");
rootPane.getActionMap().put("F1", pressF1);
Alguem sabe o que pode estar acontecendo?!
Desde já agradeço!
