Examples of java.awt.Component.invalidate()

java.awt.Component.invalidate()
Invalidates this component. This component and all parents above it are marked as needing to be laid out. This method can be called often, so it needs to execute quickly. @see #validate @see #doLayout @see LayoutManager @since JDK1.0

            ((JComponent)comp).setMinimumSize(newSize );
        }
        else {
            comp.setSize(this.value, comp.getHeight());
            // Force a layout
            comp.invalidate();
            comp.validate();
        }
    }
    public static void set(Component comp, int value){
        ActionMgr.addAction(new WidthInPixels(comp, value));
