Examples of java.awt.Component.validate()

java.awt.Component.validate()
Ensures that this component has a valid layout. This method is primarily intended to operate on instances of Container. @see #invalidate @see #doLayout() @see LayoutManager @see Container#validate @since JDK1.0

        Component c = e.getComponent().getParent();
        if (c != null && !this.isAdjusting) {
          // TF:03/11/2008:Added in an invalidate, because our parent wasn't necessarily getting
          // laid out properly because it might still be valid.
          c.invalidate();
            c.validate();
            e.getComponent().validate();
        }
    }
