 Posted: Tue Jul 07, 2009 11:14 pm Post subject: Getting the beans property at runtime. |
 |
|
I have made a bean component automatically created by netbeans.Then I bind a jtextfield's text property to that bean's property and in my main method I set the property for that bean.Yet, I m not getting the property name in my textfield after the program runs.Can anybody help.
Here is the bean component that netbeans created for me by default.
| Code: | package saraelectro;
import java.beans.*;
import java.io.Serializable;
public class myBean implements Serializable {
public static final String PROP_SAMPLE_PROPERTY = "sampleProperty";
private String sampleProperty;
private PropertyChangeSupport propertySupport;
public myBean() {
propertySupport = new PropertyChangeSupport(this);
}
public String getSampleProperty() {
return sampleProperty;
}
public void setSampleProperty(String value) {
String oldValue = sampleProperty;
sampleProperty = value;
propertySupport.firePropertyChange(PROP_SAMPLE_PROPERTY, oldValue, sampleProperty);
}
public void addPropertyChangeListener(PropertyChangeListener listener) {
propertySupport.addPropertyChangeListener(listener);
}
public void removePropertyChangeListener(PropertyChangeListener listener) {
propertySupport.removePropertyChangeListener(listener);
}
} |
This is my main method to set the property of that bean.
| Code: | public static void main(String[] args) {
myBean bn= new myBean();
bn.setSampleProperty("This text should go into the jtextfield");
myFrame frm=new myFrame();
frm.setVisible(true);
} |
And that is what netbeans created after I bound jtextfield's text property to my beans' property.
| Code: | bindingGroup = new org.jdesktop.beansbinding.BindingGroup();
org.jdesktop.beansbinding.Binding binding = org.jdesktop.beansbinding.Bindings.createAutoBinding(org.jdesktop.beansbinding.AutoBinding.UpdateStrategy.READ_WRITE, myBean1, org.jdesktop.beansbinding.ELProperty.create("${sampleProperty}"), myTextField, org.jdesktop.beansbinding.BeanProperty.create("text"));
bindingGroup.addBinding(binding); |
WHY am I not getting that value of my bean in my textfield?? |
