Examples of java.awt.Container.validate()

java.awt.Container.validate()
Validates this container and all of its subcomponents.
The validate method is used to cause a container to lay out its subcomponents again. It should be invoked when this container's subcomponents are modified (added to or removed from the container, or layout-related information changed) after the container has been displayed.
If this {@code Container} is not valid, this method invokesthe {@code validateTree} method and marks this {@code Container}as valid. Otherwise, no action is performed. @see #add(java.awt.Component) @see Component#invalidate @see javax.swing.JComponent#revalidate() @see #validateTree

            if (p != null) {
              if (p instanceof JComponent) {
                ((JComponent) p).revalidate();
              } else {
                parent.invalidate();
                p.validate();
              }
            }
          }
        });
