public class MightySlider
extends Canvas
implements MouseListener, MouseMotionListener
A Slider is a widget that varies between a minimum and a maximum value. The user can drag a "thumb" to change the current value. As the slider is dragged, Motion() is called. When the slider is released, Release() is called. Override these two methods to give the slider behavior.

Method Index

o getMinimumSize()
The minimum size of this slider is determined by any resizes the user has called on this component between the time it was instantiated and the time at which it is added to the layout manager (which calls this getMinimumSize() method), or if the user has not resized this component, the default height and width are used.
o getPreferredSize()
The preferred size for this slider component is the same as its minimum size.
o GetValue()
Returns the current value for the slider.
o Motion()
This method is called when the "thumb" of the slider is dragged by the user.
o mouseClicked(MouseEvent)
o mouseDragged(MouseEvent)
And the MouseMotionListener methods.
o mouseEntered(MouseEvent)
o mouseExited(MouseEvent)
o mouseMoved(MouseEvent)
o mousePressed(MouseEvent)
Here are the MouseListener methods.
o mouseReleased(MouseEvent)
An internal method used to handle mouse up events.
o paint(Graphics)
An internal method used to handle repaint events.
o Release()
This method is called when the "thumb" of the slider is released after being dragged.
o SetBackgroundColor(Color)
Sets the background color for the slider.
o SetBarColor(Color)
Sets the color for the slider's bar.
o setBounds(int, int, int, int)
An internal method used to handle resizing.

Constructors

o MightySlider

Constructs a slider.

Methods

o SetDoubleMode 
 public void SetDoubleMode(boolean theMode)
o getPreferredSize 
 public Dimension getPreferredSize()
The preferred size for this slider component is the same as its minimum size.

Overrides:
getPreferredSize in class Component
o getMinimumSize 
 public Dimension getMinimumSize()
The minimum size of this slider is determined by any resizes the user has called on this component between the time it was instantiated and the time at which it is added to the layout manager (which calls this getMinimumSize() method), or if the user has not resized this component, the default height and width are used. The programmer should be careful to ensure that they do not resize this component to a size smaller than is needed to fit the display value (since no checking is done here to prevent that case).

Overrides:
getMinimumSize in class Component
o Motion 
 public void Motion()
This method is called when the "thumb" of the slider is dragged by the user. Must be overridden to give the slider some behavior.

o Release 
 public void Release()
This method is called when the "thumb" of the slider is released after being dragged. Must be overridden to give the slider some behavior.

o SetMaximum 
 public void SetMaximum(double num)
Sets the maximum value for the slider.

Parameters:
num - The new maximum (passed as a double).
o SetMaximum 
 public void SetMaximum(int num)
Sets the maximum value for the slider.

Parameters:
num - The new maximum (passed as an integer).
o SetMinimum 
 public void SetMinimum(double num)
Sets the minimum value for the slider.

Parameters:
num - The new minimum (passed as a double).
o SetMinimum 
 public void SetMinimum(int num)
Sets the minimum value for the slider.

Parameters:
num - The new minimum (passed as an integer).
o SetValue 
 public void SetValue(double num)
Sets the current value for the slider. The thumb will move to reflect the new setting.

Parameters:
num - The new setting for the slider (passed as a double).
o SetValue 
 public void SetValue(int num)
Sets the current value for the slider. The thumb will move to reflect the new setting.

Parameters:
num - The new setting for the slider (passed as an integer).
o SetHeight 
 public void SetHeight(int num)
Sets the height of the slider. This is the height of the entire slider canvas, including space reserved for displaying the current value.

Parameters:
num - The new height.
o SetWidth 
 public void SetWidth(int num)
Sets the width of the slider. This is the width of the actual slider box.

Parameters:
num - The new width.
o GetValue 
 public double GetValue()
Returns the current value for the slider.

Returns:
The current value for the slider.
o SetBackgroundColor 
 public void SetBackgroundColor(Color color)
Sets the background color for the slider. The "background" is the area outside of the bar.

Parameters:
color - The new background color.
o SetThumbColor 
 public void SetThumbColor(Color color)
Sets the color for the slider's thumb. The "thumb" is the box that the user can slide back and forth.

Parameters:
color - The new thumb color.
o SetBarColor 
 public void SetBarColor(Color color)
Sets the color for the slider's bar. The "bar" is the rectangle that the thumb slides around in.

Parameters:
color - The new bar color.
o SetSlashColor 
 public void SetSlashColor(Color color)
Sets the slash color for the slider. The "slash" is the little vertical line on the thumb.

Parameters:
color - The new slash color.

 public void SetTextColor(Color color)
Sets the color for the slider`s text.

Parameters:
color - The new text color.
o SetFont 
 public void SetFont(Font font)
Sets the font for the slider`s text.

Parameters:
font - The new font.
o paint 
 public void paint(Graphics g)
An internal method used to handle repaint events.

Overrides:
paint in class Canvas
o mousePressed 
 public void mousePressed(MouseEvent evt)
Here are the MouseListener methods. Only two are nontrivial. An internal method used to handle mouse down events.

o mouseReleased 
 public void mouseReleased(MouseEvent evt)
An internal method used to handle mouse up events.

o mouseClicked 
 public void mouseClicked(MouseEvent evt)
o mouseEntered 
 public void mouseEntered(MouseEvent evt)
o mouseExited 
 public void mouseExited(MouseEvent evt)
o mouseDragged 
 public void mouseDragged(MouseEvent evt)
And the MouseMotionListener methods. Only need the drag one. An internal method used to handle mouse drag events.

o mouseMoved

o setBounds 
 public void setBounds(int x,
                       int y,
                       int width,
                       int height)
