Class SynthButtonUI

    • Constructor Detail

      • SynthButtonUI

        public SynthButtonUI()
    • Method Detail

      • createUI

        public static ComponentUI createUI(JComponent c)
        Creates a new UI object for the given component.
        Parameters:
        c - component to create UI object for
        Returns:
        the UI object
      • 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 BasicButtonUI
        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
      • getDefaultIcon

        protected Icon getDefaultIcon(AbstractButton b)
        Returns the default icon. This should not callback to the JComponent.
        Parameters:
        b - button the icon is associated with
        Returns:
        default icon
      • getIcon

        protected Icon getIcon(AbstractButton b)
        Returns the Icon to use for painting the button. The icon is chosen with respect to the current state of the button.
        Parameters:
        b - button the icon is associated with
        Returns:
        an icon
      • 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 BasicButtonUI
        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
        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 BasicButtonUI
        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:
        a Dimension object or null
        See Also:
        JComponent.getMaximumSize(), LayoutManager2.maximumLayoutSize(java.awt.Container)
      • getSizingIcon

        protected Icon getSizingIcon(AbstractButton b)
        Returns the Icon used in calculating the preferred/minimum/maximum size.
      • propertyChange

        public void propertyChange(PropertyChangeEvent e)
        This method gets called when a bound property is changed.
        Specified by:
        propertyChange in interface PropertyChangeListener
        Parameters:
        e - A PropertyChangeEvent object describing the event source and the property that has changed.
