How to get the size of 'MyComponent' when it is used in another place ?

Question

'My component' is JPanel based ( for example)
I find problems to use the real size of MyComponent ( the size it has at the destiny)
In 'Initialize' this.getheight gives me the size of the component by itself
Must I use 'paintComponent' to know the real size or where ?
By other side, must I count 2 paintComponent() ( the first 2 times paintCompnent is called by the 'system' , one for width and one for height ) to make sure the component is already drawed ?
Thank you

Yes, very simply :
import javax.swing.JPanel;
import java.awt.Rectangle;
import javax.swing.JLabel;
public class Wdes extends JPanel {
     private static final long serialVersionUID = 1L;
     private JLabel jLabel = null;
     public Wdes() {
          super();
          initialize();
     private void initialize() {
          jLabel = new JLabel();
          jLabel.setBounds(new Rectangle(8, 45, 268, 24));
          jLabel.setText("hello : mi size at destiny container is :");
          this.setLayout(null);
          this.setSize(300, 117);
          this.add(jLabel, null);     
          public void paint(Graphics g) {
          System.out.println("paint"+this.getWidth()+ " "+ this.getHeight());
     public void paintComponent(Graphics g) {
          System.out.println("paintcomponent"+this.getWidth()+ " "+ this.getHeight());
}As you can see I have A Jlabel : jLabel.setText("hello : mi size at destiny container is :");
Ok, I put this bean onto my application and I give it the size desired.
I can use paint or paintcomponent to know my real size , isn't it ? ( and please forget my initial condition of 2 paint events ... -simply I come from VB ...- )
Is there another way ?
And, I dont know what is happen but in this example only work paint ( paintComponent does not )
( If i want to use paintcomponent I have to delete paint , isn't it ? )
Thanks
