        public SynthProgressBarUI​()

    • Method Detail

      • createUI

        public static ComponentUI createUI​(JComponent x)
        Creates a new UI object for the given component.
        Parameters:
        x - 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 BasicProgressBarUI
        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)

      • getBox

        protected Rectangle getBox​(Rectangle r)
        Stores the position and size of the bouncing box that would be painted for the current animation index in r and returns r. Subclasses that add to the painting performed in this class's implementation of paintIndeterminate -- to draw an outline around the bouncing box, for example -- can use this method to get the location of the bouncing box that was just painted. By overriding this method, you have complete control over the size and position of the bouncing box, without having to reimplement paintIndeterminate.
        Overrides:
        getBox in class BasicProgressBarUI
        Parameters:
        r - the Rectangle instance to be modified; may be null
        Returns:
        null if no box should be drawn; otherwise, returns the passed-in rectangle (if non-null) or a new rectangle
        See Also:
        BasicProgressBarUI.setAnimationIndex(int)

      • setAnimationIndex

        protected void setAnimationIndex​(int newValue)
        Sets the index of the current animation frame to the specified value and requests that the progress bar be repainted. Subclasses that don't use the default painting code might need to override this method to change the way that the repaint method is invoked.
        Overrides:
        setAnimationIndex in class BasicProgressBarUI
        Parameters:
        newValue - the new animation index; no checking is performed on its value
        See Also:
        BasicProgressBarUI.incrementAnimationIndex()

      • 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)

      • paintText

        protected void paintText​(SynthContext context,
                         Graphics g,
                         String title)
        Paints the component's text.
        Parameters:
        context - context for the component being painted
        g - Graphics object used for painting
        title - the text to paint

      • 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

      • 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.

      • 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 BasicProgressBarUI
        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

        JComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)
