comment faire component swing jtextfield texte disparaît quand les onglets dans (Netbeans)

Je suis en train de travailler sur une interface graphique utilisateur qui a de multiples objets textfield que l'utilisateur entre des données dans. Lorsque le programme s'ouvre, j'ai les instructions de ce que l'utilisateur est censé entrer dans le champ défini comme le "texte". Je l'ai mis à quand l'utilisateur clique sur textfield, le texte disparaît, mais je ne peux pas comprendre comment le faire disparaître quand à onglets dans la prochaine component swing jtextfield. Je veux que l'utilisateur puisse cliquer sur le premier champ, et ne jamais avoir à utiliser la souris de nouveau, mais aussi sans avoir à aller fou sur la touche retour arrière ou suppr. Grâce

votre question est tellement ambiguë peut pas même obtenir lols
comment faire pour que le texte dans un champ de texte disparaissent lors de l'onglet dans la zone de texte. Il est facile de la faire disparaître lorsque vous cliquez sur la souris dans la zone de texte, peut-être pas tout à fait aussi facile pour l'onglet
êtes-vous sur de NetBeans ou tout autre IDE?
netbeans 6.5.1 .
stackoverflow.com/a/16306641/2277645 faire comme ceci
vous devez mettre à jour NetBeans 7.2 pour de meilleures performances
dois-je perdre le glisser-déposer gui?
ce n'est pas une grosse affaire, j'ai juste été paresseux pour apprendre tout cela sans glisser et déposer. Merci beaucoup pour votre temps.

clic droit sur votre composant textfield et goto Événements then goto Accent est ensuite sélectionnez l'accent acquise et le code apparaît à vous comme private void
```
    jTextField1FocusGained(java.awt.event.FocusEvent evt) {                                        
//TODO add your handling code here:
}   
```
maintenant modifier l' //TODO ajouter votre code de gestion des ici: et de le rendre aussi:
```
    jTextField1FocusGained(java.awt.event.FocusEvent evt) {                                        
jtextField.setText(""); 
}   
```
ainsi, lorsque vous appuyez sur la touche tab, il va obtenir le focus (si vous vous appuyez sur à partir d'un autre onglet)
- jTextField1FocusGained est souligné en gris et indique que la méthode n'est pas utilisée
- et n'est toujours pas clair le textfield quand onglets dans de précédentes textfield
- pouvez-vous me montrer une capture d'écran ?
- vous pouvez utiliser le component swing jtextfield.setText(null);
- snag.gy/nwtFs.jpg
- vous êtes la génération est comme je l'ai dit à vous? envoyez-moi votre code, je vais le corriger pour vous ok asap
- collé là-haut

alors c'est simple, vous devez utiliser un actionListener
```
   private void textfieldFocusGained(java.awt.event.FocusEvent evt) {                               
textfield.setText("");
}   
```
cela vous permettra lorsque vous appuyez sur tab, le contrôle passe au champ suivant et de le vider essayez ceci (vous pouvez l'utiliser comme il est dans votre constructeur de la classe)
```
yourtextField.addFocusListener(new FocusListener() {
public void focusGained(FocusEvent e) {
yourtextField.setText(""); 
}
public void focusLost(FocusEvent e) {
}
});      
```
maintenant, si vous êtes dans un champ de texte et appuyez sur la touche tab votre panneau de passer au champ suivant et clair son texte
- il dit que la méthode n'est pas utilisée. Je l'ai mis avec toutes les autres méthodes qui efface la zone de texte lorsque la souris est cliqué.

J'ai les instructions de ce que l'utilisateur est censé entrer

Voir Texte De L'Invite. Il vous permet de personnaliser lorsque l'invite s'affiche.

Vous pouvez utiliser un FocusListener pour déterminer le moment de votre JTextField reçoit le focus (c'est à dire devient "active" de la composante), indépendamment du fait que cela s'est produit en raison d'un clic de souris ou un onglet.

textField.addFocusListener(new FocusListener() {
@Override
public void focusGained(FocusEvent e) {
textField.setText(null); //Empty the text field when it receives focus
}
@Override
public void focusLost(FocusEvent e) {
//You could do something here when the field loses focus, if you like
}
});
