Problema com tecla de atalho[Resolvido]

Programação Java

Bom dia!

Eu estou tentando criar uma tecla de atalho…mas da o seguinte erro:

java.lang.NullPointerException

segue o codigo:

[code]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);[/code]

Alguem sabe o que pode estar acontecendo?!

Desde já agradeço!

Ou…tem outro jeito de criar tecla de atalho?

#3
  1. O jeito é esse mesmo
  2. Onde é a tal linha 1242 do arquivo PainelFinanceiro.java?
#4

a linha contem o codigo:

rootPane.getInputMap(cond).put(f1, "F1");
#5

consegui resolver o problema…

eu estava pondo este codigo em um JPanel…coloquei ele em um JDialog e funcionou…

:slight_smile:

Quem é null? o rootPane ou o inputMap(); Ponha um breakpoint nesse ponto do seu código, e veja qual dos dois está null.
