      • getScale

        public double getScale()
        Returns:
        The current scale (or zoom) factor for the entire application's display.
        See Also:
        setScale(double)

      • setScale

        public void setScale​(double newScale)
        Use this method to scale up or down (that is zoom in or out) the entire application's display.

        For the main application window, use this (and related) methods to scale the display, but for any contained windows a ScaleDecorator must be used instead.

        Parameters:
        newScale - The new scale (zoom) factor for the entire display.
        See Also:
        scaleUp(), scaleDown(), getScale()

      • scaleUp

        public void scaleUp()
        Use this method to zoom in to the application's main window (that is, make all the text and components look visually bigger).

        The scale is increased in discrete steps for each call to this method: 1, 1.25, 1.5, 2.0, then whole integer values up to a maximum of 12.

        See Also:
        setScale(double), scaleDown(), getScale()

      • scaleDown

        public void scaleDown()
        Use this method to zoom out of the application's main window (that is, to make all the text and components visually smaller).

        The scale is decreased in discrete steps for each call to this method: next whole integer down for values above 2.0, then 2.0, 1.5, 1.25, then finally 1.

        See Also:
        setScale(double), scaleUp(), getScale()

      • setVolatileImagePaintEnabled

        public void setVolatileImagePaintEnabled​(boolean enabled)
        Under some conditions, e.g. running under Linux in an applet, volatile buffering can reduce performance.
        Parameters:
        enabled - Whether or not to use volatile image painting.
