Behavior of BeanDescriptor isContainer not clear

[schreuerp]

Swing Designer does not prevent adding a component as a child into a self written swing component which is not allowed to have children (like JLabel).
Neither annotations nor the isContainer-Property in the bean descriptor is considered. What else can I do? Actually, does Swing Designer support this feature?

Code: Select all

public BeanDescriptor getBeanDescriptor()
  {
    BeanDescriptor descriptor = new BeanDescriptor(beanClass);
    descriptor.setValue("isContainer", Boolean.FALSE);
    return descriptor;
  }


Code: Select all

  @beaninfo
      attribute: isContainer false


Version: 6.8.0 in RAD 7.0.0.7, Windows XP

Try this again using the latest build.

Thanks! "isContainer" in the BeanDescriptor of the BeanInfo-class now works as supposed (since Dev Build 2008.10.22).
However, the property is not considered in subclasses. Therefore, one has to write B_BeanInfo and A_BeanInfo while B extends A.

My understanding is that is the expected JavaBean behavior unless you explicitly inherit the attributes as shown here in the section titled "BeanInfo and inherent attributes"...

I dare say you're right.

I hope it works with the suggestion at the above link.
