Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.

Constructor Detail

MetalSliderUI

public MetalSliderUI()

Method Detail

createUI

public static ComponentUI createUI(JComponent c)

Description copied from class: ComponentUI

Returns an instance of the UI delegate for the specified component. Each subclass must provide its own static createUI method that returns an instance of that UI delegate subclass. If the UI delegate subclass is stateless, it may return an instance that is shared by multiple components. If the UI delegate is stateful, then it should return a new instance per component. The default implementation of this method throws an error, as it should never be invoked.

installUI

public void installUI(JComponent c)

Description copied from class: ComponentUI

Configures the specified component appropriate for the look and feel. This method is invoked when the ComponentUI instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:

1. Install any default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
2. Install a LayoutManager on the component if necessary.
3. Create/add any required sub-components to the component.
4. Create/install event listeners on the component.
5. Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
6. Install keyboard UI (mnemonics, traversal, etc.) on the component.
7. Initialize any appropriate instance data.

createPropertyChangeListener

protected java.beans.PropertyChangeListener createPropertyChangeListener(JSlider slider)

Overrides:

paintThumb

public void paintThumb(Graphics g)

Overrides:

paintThumb in class BasicSliderUI

paintTrack

public void paintTrack(Graphics g)

Overrides:

paintTrack in class BasicSliderUI

paintFocus

public void paintFocus(Graphics g)

Overrides:

paintFocus in class BasicSliderUI

getThumbSize

protected Dimension getThumbSize()

Overrides:

getThumbSize in class BasicSliderUI

getTickLength

public int getTickLength()

Gets the height of the tick area for horizontal sliders and the width of the tick area for vertical sliders. BasicSliderUI uses the returned value to determine the tick area rectangle.

Overrides:

getTickLength in class BasicSliderUI

getTrackWidth

protected int getTrackWidth()

Returns the shorter dimension of the track.

getTrackLength

protected int getTrackLength()

Returns the longer dimension of the slide bar. (The slide bar is only the part that runs directly under the thumb)

getThumbOverhang

protected int getThumbOverhang()

Returns the amount that the thumb goes past the slide bar.

scrollDueToClickInTrack

protected void scrollDueToClickInTrack(int dir)

Description copied from class: BasicSliderUI

This function is called when a mousePressed was detected in the track, not in the thumb. The default behavior is to scroll by block. You can override this method to stop it from scrolling or to add additional behavior.

Overrides:
