MetalSliderUI

public MetalSliderUI()

Constructs a new instance.

createPropertyChangeListener

protected PropertyChangeListener createPropertyChangeListener(JSlider slider)

Creates a property change listener for the slider.
Overrides:
createPropertyChangeListener in interface BasicSliderUI
Parameters:
slider - the slider.
Returns:
A new instance of MetalSliderUI.MetalPropertyListener.

createUI

public static ComponentUI createUI(JComponent component)

Returns a new instance of MetalSliderUI.
Overrides:
createUI in interface BasicSliderUI
Parameters:
component - the component (ignored).
Returns:
A new instance of MetalSliderUI.

getThumbOverhang

protected int getThumbOverhang()

Returns the thumb overhang.
Returns:
The thumb overhang.

getThumbSize

protected Dimension getThumbSize()

Returns the size of the thumb icon.
Overrides:
getThumbSize in interface BasicSliderUI
Returns:
The size of the thumb icon.

getTickLength

public int getTickLength()

Returns the length of the major tick marks.
Overrides:
getTickLength in interface BasicSliderUI
Returns:
The length of the major tick marks.

getTrackLength

protected int getTrackLength()

Returns the track length.
Returns:
The track length.

getTrackWidth

protected int getTrackWidth()

Returns the track width.
Returns:
The track width.

installUI

public void installUI(JComponent c)

Installs the default for this UI delegate in the supplied component.
Overrides:
installUI in interface BasicSliderUI
Parameters:
c - the component.

paintFocus

public void paintFocus(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 interface BasicSliderUI
Parameters:
g - the graphics device.

paintMajorTickForHorizSlider

protected void paintMajorTickForHorizSlider(Graphics g,
                                            Rectangle tickBounds,
                                            int x)

Paints the major ticks for a slider with a horizontal orientation.
Overrides:
paintMajorTickForHorizSlider in interface BasicSliderUI
Parameters:
g - the graphics device.
tickBounds - the tick bounds.
x - the x value for the tick.

paintMajorTickForVertSlider

protected void paintMajorTickForVertSlider(Graphics g,
                                           Rectangle tickBounds,
                                           int y)

Paints the major ticks for a slider with a vertical orientation.
Overrides:
paintMajorTickForVertSlider in interface BasicSliderUI
Parameters:
g - the graphics device.
tickBounds - the tick bounds.
y - the y value for the tick.

paintMinorTickForHorizSlider

protected void paintMinorTickForHorizSlider(Graphics g,
                                            Rectangle tickBounds,
                                            int x)

Paints the minor ticks for a slider with a horizontal orientation.

tickBounds - the tick bounds.
x - the x value for the tick.

paintMinorTickForVertSlider

protected void paintMinorTickForVertSlider(Graphics g,
                                           Rectangle tickBounds,
                                           int y)

Paints the minor ticks for a slider with a vertical orientation.

Parameters:
g - the graphics device.
tickBounds - the tick bounds.
y - the y value for the tick.
