      • createUI

        public static ComponentUI createUI​(JComponent c)
        Constructs a new MetalPopupMenuSeparatorUI instance.
        Parameters:
        c - a component
        Returns:
        a new MetalPopupMenuSeparatorUI instance

      • paint

        public void paint​(Graphics g,
                  JComponent c)
        Description copied from class: ComponentUI
        Paints the specified component appropriately for the look and feel. This method is invoked from the ComponentUI.update method when the specified component is being painted. Subclasses should override this method and use the specified Graphics object to render the content of the component.
        Overrides:
        paint in class MetalSeparatorUI
        Parameters:
        g - the Graphics context in which to paint
        c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

        ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)

      • getPreferredSize

        public Dimension getPreferredSize​(JComponent c)
        Description copied from class: ComponentUI
        Returns the specified component's preferred size appropriate for the look and feel. If null is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null.
        Overrides:
        getPreferredSize in class MetalSeparatorUI
        Parameters:
        c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
        Returns:
        a Dimension object containing given component's preferred size appropriate for the look and feel
