public class PercentDial
extends Canvas

PercentDial is a custom component that takes a value between 0.0 and 1.0 (inclusive) and displays the corresponding fraction of a circle with a filled arc.

PercentDial(int): Contructor which assumes the default border thickness.
PercentDial(int, int): Constructor which takes the width of the component (and incidentally the height) in pixels and the thickness of the border in pixels.

getHeight(): The total height of the component in pixels.
getMinimumSize(): Overrides Component.getMinimumSize to return the minimum size of the Percent Dial.
getOutlineColor(): Returns the color for the outline of the circle.
getPreferredSize(): Overrides Component.getPreferredSize to return the preferred size of the Percent Dial.
getUnusedColor(): Returns the fill color for the portion of the circle which shows the fraction which is not used.
getUsedColor(): Returns the fill color for the portion of the circle which shows the fraction used.
getWidth(): The total width of the component in pixels.
minimumSize(): Still here for backward 1.0 compat
paint(Graphics): Overrides paint() method to draw the percent dial.
preferredSize(): Still here for backward 1.0 compat
setCurrFrac(double): Update the percent dial to show a new fraction of the circle.
setOutlineColor(Color): Sets the color for the outline of the circle.
setUnusedColor(Color): Sets the fill color for the portion of the circle which shows the fraction which is not used.
setUsedColor(Color): Sets the fill color for the portion of the circle which shows the fraction used.

PercentDial

 public PercentDial(int totalWidth,
                    int pixelBorder)

Constructor which takes the width of the component (and incidentally the height) in pixels and the thickness of the border in pixels. The diameter of the circle will be: width - 2*border pixels.

PercentDial

 public PercentDial(int totalWidth)

Contructor which assumes the default border thickness.

getWidth

 public int getWidth()

The total width of the component in pixels.

getHeight

 public int getHeight()

The total height of the component in pixels.

getPreferredSize

 public Dimension getPreferredSize()

Overrides Component.getPreferredSize to return the preferred size of the Percent Dial.

Overrides:: getPreferredSize in class Component

getMinimumSize

 public Dimension getMinimumSize()

Overrides Component.getMinimumSize to return the minimum size of the Percent Dial.

Overrides:: getMinimumSize in class Component

preferredSize

 public Dimension preferredSize()

setUsedColor

 public void setUsedColor(Color c)

Sets the fill color for the portion of the circle which shows the fraction used.

setUnusedColor

 public void setUnusedColor(Color c)

Sets the fill color for the portion of the circle which shows the fraction which is not used.

setOutlineColor

 public void setOutlineColor(Color c)

Sets the color for the outline of the circle.

getUsedColor

 public Color getUsedColor()

Returns the fill color for the portion of the circle which shows the fraction used.

getUnusedColor

 public Color getUnusedColor()

Returns the fill color for the portion of the circle which shows the fraction which is not used.

getOutlineColor

 public Color getOutlineColor()

Returns the color for the outline of the circle.

paint

 public void paint(Graphics g)

Overrides paint() method to draw the percent dial.

Overrides:: paint in class Canvas

setCurrFrac

 public void setCurrFrac(double currFrac)

Update the percent dial to show a new fraction of the circle. The currFrac value should be in the range 0.0 to 1.0 (inclusive).
