java bean init component?

[Peter]

Hi
I am writting a Java Bean which extends JPanel, inside the jpanel,
it contains many other component , such as jbutton, jtable.

In the constructor of this Java Bean, the getSize() of those
components give me 0,0, So where should i put the init code in?

i tried : hierarchyChanged(), propertyChanged(), vetoableChange(),
focusGain(), componentAdded(), componentShown() event, but still give
me 0,0

thanks

It is rarely appropriate to subclass JPanel. It is usually better to
use a standard JPanel and create a method in your application to
populate it appropriately. As another poster has noted, you should
normally use an appropriate LayoutManager to arrange the JPanel's
contents; when that is done it is very uncommon for the application code
to need the size of the contained components.

The contained components don't have a size until their container is laid
out. You can accomplish that with pack().
