      • installDefaults

        protected void installDefaults​(JLabel c)
        Installs default properties.

        Parameters:
        c - an instance of JLabel
      • uninstallDefaults

        protected void uninstallDefaults​(JLabel c)
        Uninstalls default properties.

        c - an instance of JLabel
      • getContext

        public SynthContext getContext​(JComponent c)
        Returns the Context for the specified component.
        Specified by:
        getContext in interface SynthUI
        Parameters:
        c - Component requesting SynthContext.
        Returns:
        SynthContext describing component.
      • getBaseline

        public int getBaseline​(JComponent c,
                               int width,
                               int height)
        Returns the baseline.
        Overrides:
        getBaseline in class BasicLabelUI
        Parameters:
        c - JComponent baseline is being requested for
        width - the width to get the baseline for
        height - the height to get the baseline for
        Returns:
        baseline or a value < 0 indicating there is no reasonable baseline
        See Also:
        JComponent.getBaseline(int, int)
      • update

        public void update​(Graphics g,
                           JComponent c)
        Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls the paint(SynthContext,Graphics) method.

        In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the paint method.

        Overrides:
        update in class ComponentUI
        Parameters:
        g - the Graphics object used for painting
        c - the component being painted
        See Also:
        paint(SynthContext,Graphics)
      • paint

        protected void paint​(SynthContext context,
                             Graphics g)
        Paints the specified component.
        Parameters:
        context - context for the component being painted
        g - the Graphics object used for painting
        See Also:
        update(Graphics,JComponent)
      • paintBorder

        public void paintBorder​(SynthContext context,
                                Graphics g,
                                int x,
                                int y,
                                int w,
                                int h)
        Paints the border.
        Specified by:
        paintBorder in interface SynthUI
        Parameters:
        context - a component context
        g - Graphics to paint on
        x - the X coordinate
        y - the Y coordinate
        w - width of the border
        h - height of the border
      • getPreferredSize

        public Dimension getPreferredSize​(JComponent c)
        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 BasicLabelUI
        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
        See Also:
        JComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)
      • getMaximumSize

        public Dimension getMaximumSize​(JComponent c)
        Returns the specified component's maximum size appropriate for the look and feel. If null is returned, the maximum 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 invokes getPreferredSize and returns that value.
        Overrides:
        getMaximumSize in class BasicLabelUI
        Parameters:
        c - the component whose maximum 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:
        getPreferredSize(c)
        See Also:
        JComponent.getMaximumSize(), LayoutManager2.maximumLayoutSize(java.awt.Container)
