Como fazer o JText em requestFocus()?

Programação Java
#1

OLá ! Não se qual o erro no código , pois já fiz no final do código o " tfResposta.requestFocus();"
, então quando dou o run , ele não foca no tfResposta , mas foca em outro botão.(btnSair)
Eu quero que foca no tfResposta.
Alguém pode me ajudar ?

Tenta

 seuTxtField.grabFocus();
1 curtida
#3

Ok

#4

Infelizmente não funcionou !!!

#5

nao funcionou pq? como vc tentou? explica a situação, mostra o codigo q vc tentou.

Vc pode fazer assim tbm:

botaoSair.setFocusable(false);

Mas isso é algo bem manual, se vc fizer isso em um textField, terá que dar um true depois que a tela abrir

#6

Entao , quando a tela abre , eu clico no jTextfield e depois que avanco nas proximas etapas ele funciona direitinho .

#7

tenta usar

if (this.nomeDoTextField.getText().isEmpty()) {
(opcional) JOptionPane.showMessageDialog((Component)null, “Preencha o campo nome”);
this.nomeDoTextField.requestFocus();
}
