public class HorizontalSlider

extends Slider

See Also:

VerticalSlider

TICK_HEIGHT

Length of the gauge ticks in pixels.

HorizontalSlider()

Constructs a default HorizontalSlider.

doMove(int, boolean)

This routine updates the thumb position, paints the HorizontalSlider, and posts a new action event as needed.

getTickStyle()

Returns the current slider tick mark style.

mouseDown(Event, int, int)

Processes MOUSE_DOWN events.

mouseDrag(Event, int, int)

Processes MOUSE_DRAG events.

paint(Graphics)

Paints this component using the given graphics context.

reshape(int, int, int, int)

Moves and/or resizes this component.

setTickStyle(int)

Sets the current slider tick mark style.

validate()

Ensures that this component is laid out properly, as needed.

  protected final static int TICK_HEIGHT

Length of the gauge ticks in pixels.

  public HorizontalSlider()

Constructs a default HorizontalSlider. The ticks are drawn on both sides of the gauge with a frequency of 1. The minimum value is 1. The maximum value is 10. The border is shown.

  public void setTickStyle(int style)

Sets the current slider tick mark style.

See Also:

getTickStyle, TICK_TOP, TICK_BOTTOM, TICK_BOTH

  public int getTickStyle()

Returns the current slider tick mark style.

Overrides:

getTickStyle in class Slider

See Also:

setTickStyle, TICK_TOP, TICK_BOTTOM, TICK_BOTH

  public boolean mouseDown(Event e,
                           int x,
                           int y)

Processes MOUSE_DOWN events. This is a standard Java AWT method which gets called by the AWT method handleEvent() in response to receiving a MOUSE_DOWN event. These events occur when the mouse button is pressed while inside this component.

Parameters:

e - the event

x - the component-relative horizontal coordinate of the mouse

y - the component-relative vertical coordinate of the mouse

Returns:

always true since the event was handled

Overrides:

mouseDown in class Component

See Also:

mouseUp, handleEvent

  public boolean mouseDrag(Event e,
                           int x,
                           int y)

Processes MOUSE_DRAG events. This is a standard Java AWT method which gets called by the AWT method handleEvent() in response to receiving a MOUSE_DRAG event. These events occur when the mouse is moved around inside this component while the button is pressed.

Parameters:

e - the event

x - the component-relative horizontal coordinate of the mouse

y - the component-relative vertical coordinate of the mouse

Returns:

always true since the event was handled

Overrides:

mouseDrag in class Component

See Also:

mouseMove, handleEvent

  public void reshape(int x,
                      int y,
                      int w,
                      int h)

Moves and/or resizes this component. This is a standard Java AWT method which gets called to move and/or resize this component. Components that are in containers with layout managers should not call this method, but rely on the layout manager instead.

Parameters:

x - horizontal position in the parent's coordinate space

y - vertical position in the parent's coordinate space

width - the new width

height - the new height

Overrides:

reshape in class Component

  public void paint(Graphics g)

Paints this component using the given graphics context. This is a standard Java AWT method which typically gets called by the AWT to handle painting this component. It paints this component using the given graphics context. The graphics context clipping region is set to the bounding rectangle of this component and its <0,0> coordinate is this component's top-left corner.

Parameters:

g - the graphics context used for painting

Overrides:

paint in class Canvas

See Also:

repaint, update

  protected void doMove(int pos,
                        boolean forcePost)

This routine updates the thumb position, paints the HorizontalSlider, and posts a new action event as needed. If the thumb position has changed or the forcePost parameter is true the component will be painted and an action event posted.

Parameters:

pos - the new thumb position

forcePost - true forces painting the slider and posting of an action event even if the thumb position hasn't changed

Overrides:

doMove in class Slider

  public void validate()

Ensures that this component is laid out properly, as needed. This is a standard Java AWT method which gets called by the AWT to make sure this component and its subcomponents have a valid layout. If this component was made invalid with a call to invalidate(), then it is laid out again.

Overrides:

validate in class Component

See Also:

invalidate
