Netbeans 6M9, rote Kreuzchen und Databinding in Matisse

Das ist ja lustig. Gestern habe ich mir Netbeans 6M9 installiert und festgestellt, dass Sie die Kreuzchen eingebaut haben, die ich mir gewünscht habe. DANKE! Nun sieht man auch, wenn die Folder in einem Projekt eingeklappt sind, dass es noch Fehler gibt.

Ausserdem habe mir noch schnell das Databinding angeschaut, welches jetzt von Matisse unterstützt wird. Nun ja, innerhalb eines NB-Modules habe ich es nicht zum laufen gebracht. Im GUIFormExample ging es dann aber.

Ich habe dazu eine Variable in die Klasse Antenna angelegt:

public class Antenna extends javax.swing.JFrame {

private double direction = 111.111;

public double getDirection() {
return direction;
}

public void setDirection(double direction) {
this.direction = direction;
}

Dann die Verbindung gemacht. Rechte Maustaste auf das Textfeld von Direction und dort –> bind –> text –> (und siehe bild)

Noch schnell ein Converter für Doubles in Antenna implementiert:

private BindingConverter DOUBLE_TO_STRING_CONVERTER = new BindingConverter(){

public Object sourceToTarget(Object value) {
return ((Double) value).toString();
}

@Override
public Object targetToSource(Object value) {
return Double.parseDouble((String)value);
}
};

Und diesen ins Binding eingetragen:

Fertig… Beim Öffnen des Dialoges wird jetzt magischer Weise 111.111 angzeigt.

Hier noch der vollständige Code:

package examples;

import javax.beans.binding.BindingConverter;

public class Antenna extends javax.swing.JFrame {

private double direction = 111.111;

public double getDirection() {
return direction;
}

public void setDirection(double direction) {
this.direction = direction;
}

private BindingConverter DOUBLE_TO_STRING_CONVERTER = new BindingConverter(){

public Object sourceToTarget(Object value) {
return ((Double) value).toString();
}

@Override
public Object targetToSource(Object value) {
return Double.parseDouble((String)value);
}
};
