javax.swing
public class: SwingBeanInfoBase [javadoc | source]

java.lang.Object
   java.beans.SimpleBeanInfo
      javax.swing.SwingBeanInfoBase

All Implemented Interfaces:
BeanInfo

The superclass for all Swing BeanInfo classes. It provides default implementations of getIcon and getDefaultPropertyIndex as well as utility methods, like createPropertyDescriptor, for writing BeanInfo implementations. This classes is intended to be used along with GenSwingBeanInfo a BeanInfo class code generator.

Method from javax.swing.SwingBeanInfoBase Summary:
getAdditionalBeanInfo, getDefaultPropertyIndex, getIcon

Methods from java.beans.SimpleBeanInfo:
getAdditionalBeanInfo, getBeanDescriptor, getDefaultEventIndex, getDefaultPropertyIndex, getEventSetDescriptors, getIcon, getMethodDescriptors, getPropertyDescriptors, loadImage

Methods from java.lang.Object:
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Method from javax.swing.SwingBeanInfoBase Detail:
public BeanInfo[] getAdditionalBeanInfo() { Class superClass = getBeanDescriptor().getBeanClass().getSuperclass(); BeanInfo superBeanInfo = null; try { superBeanInfo = Introspector.getBeanInfo(superClass); } catch (IntrospectionException ie) {} if (superBeanInfo != null) { BeanInfo[] ret = new BeanInfo[1]; ret[0] = superBeanInfo; return ret; } return null; } Returns the BeanInfo for the superclass of our bean, so that its PropertyDescriptors will be included.
public int getDefaultPropertyIndex() { return 0; } The default index is always 0. In other words the first property listed in the getPropertyDescriptors() method is the one to show a (JFC builder) user in a situation where just a single property will be shown.
public Image getIcon(int kind) { // PENDING(hmuller) need generic swing icon images. return null; } Returns a generic Swing icon, all icon "kinds" are supported. Subclasses should defer to this method when they don't have a particular beans icon kind.

Method from javax.swing.SwingBeanInfoBase Detail:

 public BeanInfo[] getAdditionalBeanInfo() {
        Class superClass = getBeanDescriptor().getBeanClass().getSuperclass();
        BeanInfo superBeanInfo = null;
        try {
            superBeanInfo = Introspector.getBeanInfo(superClass);
        } catch (IntrospectionException ie) {}
        if (superBeanInfo != null) {
            BeanInfo[] ret = new BeanInfo[1];
            ret[0] = superBeanInfo;
            return ret;
        }
        return null;
}

Returns the BeanInfo for the superclass of our bean, so that its PropertyDescriptors will be included.

 public int getDefaultPropertyIndex() {
        return 0;
}

The default index is always 0. In other words the first property listed in the getPropertyDescriptors() method is the one to show a (JFC builder) user in a situation where just a single property will be shown.

 public Image getIcon(int kind) {
        // PENDING(hmuller) need generic swing icon images.
        return null;
}

Returns a generic Swing icon, all icon "kinds" are supported. Subclasses should defer to this method when they don't have a particular beans icon kind.
