    • Method Detail

      • setAlpha

        public void setAlpha​(float alpha)
        Set the alpha transparency level for this component. This automatically causes a repaint of the component.

        TODO add support for animated changes in translucency

        Parameters:
        alpha - must be a value between 0 and 1 inclusive.
      • getAlpha

        public float getAlpha()
        Returns:
        the alpha translucency level for this component. This will be a value between 0 and 1, inclusive.
      • getEffectiveAlpha

        public float getEffectiveAlpha()
        Unlike other properties, alpha can be set on a component, or on one of its parents. If the alpha of a parent component is .4, and the alpha on this component is .5, effectively the alpha for this component is .4 because the lowest alpha in the heirarchy "wins"

      • setBackgroundPainter

        public void setBackgroundPainter​(Painter p)
        Sets a Painter to use to paint the background of this JXPanel. By default a JXPanel already has a single painter installed which draws the normal background for a panel according to the current Look and Feel. Calling setBackgroundPainter will replace that existing painter.
        Parameters:
        p - the new painter
        See Also:
        getBackgroundPainter()
      • getBackgroundPainter

        public Painter getBackgroundPainter()
        Returns the current background painter. The default value of this property is a painter which draws the normal JPanel background according to the current look and feel.
        Returns:
        the current painter
        See Also:
        setBackgroundPainter(Painter), isPaintBorderInsets()
      • isPaintBorderInsets

        public boolean isPaintBorderInsets()
        Returns true if the background painter should paint where the border is or false if it should only paint inside the border. This property is true by default. This property affects the width, height, and intial transform passed to the background painter.
      • setPaintBorderInsets

        public void setPaintBorderInsets​(boolean paintBorderInsets)
        Sets the paintBorderInsets property. Set to true if the background painter should paint where the border is or false if it should only paint inside the border. This property is true by default. This property affects the width, height, and intial transform passed to the background painter. This is a bound property.

      • paintComponent

        protected void paintComponent​(java.awt.Graphics g)
        Overridden to provide Painter support. It will call backgroundPainter.paint() if it is not null, else it will call super.paintComponent().
