Java Module java.desktop Package javax.swing.plaf.multi Class MultiSpinnerUI（JDK11）

Field Detail

• uis

  protected Vector<ComponentUI> uis

  The vector containing the real UIs. This is populated in the call to createUI, and can be obtained by calling the getUIs method. The first element is guaranteed to be the real UI obtained from the default look and feel.

Constructor Detail

• MultiSpinnerUI

  public MultiSpinnerUI()

Method Detail

• getUIs

  public ComponentUI[] getUIs()

  Returns the list of UIs associated with this multiplexing UI. This allows processing of the UIs by an application aware of multiplexing UIs on components.

  Returns:

  an array of the UI delegates

• contains

  public boolean contains​(JComponent a,
                          int b,
                          int c)

  Invokes the contains method on each UI handled by this object.

  Overrides:

  contains in class ComponentUI

  Parameters:

  a - the component where the x,y location is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

  b - the x coordinate of the point

  c - the y coordinate of the point

  Returns:

  the value obtained from the first UI, which is the UI obtained from the default LookAndFeel
