Constructor Detail

MetalSliderUI

public MetalSliderUI()
Method Detail

createUI

public static ComponentUI createUI(JComponent c)

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.

Overrides:
installUI in class BasicSliderUI
Parameters:
c - the component where this UI delegate is being installed

createPropertyChangeListener

protected PropertyChangeListener createPropertyChangeListener(JSlider slider)
Overrides:
createPropertyChangeListener in class BasicSliderUI

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:
scrollDueToClickInTrack in class BasicSliderUI

paintMinorTickForHorizSlider

                                           int y)
Overrides:
paintMinorTickForVertSlider in class BasicSliderUI

paintMajorTickForVertSlider

protected void paintMajorTickForVertSlider(Graphics g,
                                           Rectangle tickBounds,
