Constructor Detail

MetalSliderUI

public MetalSliderUI()

Constructs a new instance.

Method Detail

createUI

public static javax.swing.plaf.ComponentUI createUI(javax.swing.JComponent component)

Returns a new instance of MetalSliderUI.

Parameters:

component - the component (ignored).

Returns:

A new instance of MetalSliderUI.

installUI

public void installUI(javax.swing.JComponent c)

Installs the default for this UI delegate in the supplied component.

Overrides:

installUI in class javax.swing.plaf.basic.BasicSliderUI

Parameters:

c - the component.

See Also:

ComponentUI.uninstallUI(javax.swing.JComponent), JComponent.setUI(javax.swing.plaf.ComponentUI), JComponent.updateUI()

createPropertyChangeListener

protected java.beans.PropertyChangeListener createPropertyChangeListener(javax.swing.JSlider slider)

Creates a property change listener for the slider.

Overrides:

createPropertyChangeListener in class javax.swing.plaf.basic.BasicSliderUI

Parameters:

slider - the slider.

Returns:

A new instance of MetalSliderUI.MetalPropertyListener.

paintThumb

public void paintThumb(java.awt.Graphics g)

Paints the thumb icon for the slider.

Overrides:

paintThumb in class javax.swing.plaf.basic.BasicSliderUI

Parameters:

g - the graphics device.

paintTrack

public void paintTrack(java.awt.Graphics g)

Paints the track along which the thumb control moves.

Overrides:

paintTrack in class javax.swing.plaf.basic.BasicSliderUI

Parameters:

g - the graphics device.

paintFocus

public void paintFocus(java.awt.Graphics g)

Draws the focus rectangle for the slider. The Metal look and feel indicates that the JSlider has the focus by changing the color of the thumb control - this is handled elsewhere and so this method is empty (it overrides the method in the BasicSliderUI class to prevent a default focus highlight from being drawn).

Overrides:

paintFocus in class javax.swing.plaf.basic.BasicSliderUI

Parameters:

g - the graphics device.

getThumbSize

protected java.awt.Dimension getThumbSize()

Returns the size of the thumb icon.

Overrides:

getThumbSize in class javax.swing.plaf.basic.BasicSliderUI

Returns:

The size of the thumb icon.

getTickLength

public int getTickLength()

Returns the length of the major tick marks.

Overrides:

getTickLength in class javax.swing.plaf.basic.BasicSliderUI

Returns:

The length of the major tick marks.

getTrackWidth

protected int getTrackWidth()

Returns the track width.

Returns:

The track width.

getTrackLength

protected int getTrackLength()

Returns the track length.

Returns:

The track length.

getThumbOverhang

protected int getThumbOverhang()

Returns the thumb overhang.

Returns:

The thumb overhang.
