Class SkinRootPaneUI

All Implemented Interfaces:
PropertyChangeListener, EventListener

public final class SkinRootPaneUI extends BasicRootPaneUI
Provides the metal look and feel implementation of RootPaneUI.

MetalRootPaneUI provides support for the windowDecorationStyle property of JRootPane.MetalRootPaneUI does this by way of installing a custom LayoutManager, a private Component to render the appropriate widgets, and a private Border. The LayoutManager is always installed, regardless of the value of the windowDecorationStyle property, but the Border and Component are only installed/added if the windowDecorationStyle is other than JRootPane.NONE.

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.

    • createUI

      public static ComponentUI createUI(JComponent c)
      Creates a UI for a JRootPane.
      Parameters:
      c - the JRootPane the RootPaneUI will be created for
      Returns:
      the RootPaneUI implementation for the passed in JRootPane
    • installUI

      public void installUI(JComponent c)
      Invokes supers implementation of installUI to install the necessary state onto the passed in JRootPane to render the metal look and feel implementation of RootPaneUI. If the windowDecorationStyle property of the JRootPane is other than JRootPane.NONE, this will add a custom Component to render the widgets to JRootPane, as well as installing a custom Border and LayoutManager on the JRootPane.
      Overrides:
      installUI in class BasicRootPaneUI
      Parameters:
      c - the JRootPane to install state onto
    • uninstallUI

      public void uninstallUI(JComponent c)
      Invokes supers implementation to uninstall any of its state. This will also reset the LayoutManager of the JRootPane. If a Component has been added to the JRootPane to render the window decoration style, this method will remove it. Similarly, this will revert the Border and LayoutManager of the JRootPane to what it was before installUI was invoked.
      Overrides:
      uninstallUI in class BasicRootPaneUI
      Parameters:
      c - the JRootPane to uninstall state from
    • propertyChange

      public void propertyChange(PropertyChangeEvent e)
      Invoked when a property changes. MetalRootPaneUI is primarily interested in events originating from the JRootPane it has been installed on identifying the property windowDecorationStyle. If the windowDecorationStyle has changed to a value other than JRootPane.NONE, this will add a Component to the JRootPane to render the window decorations, as well as installing a Border on the JRootPane. On the other hand, if the windowDecorationStyle has changed to JRootPane.NONE, this will remove the Component that has been added to the JRootPane as well resetting the Border to what it was before installUI was invoked.
      Specified by:
      propertyChange in interface PropertyChangeListener
      Overrides:
      propertyChange in class BasicRootPaneUI
      Parameters:
      e - A PropertyChangeEvent object describing the event source and the property that has changed.
    • adjust

      public static void adjust(Rectangle bounds, Dimension min, int deltaX, int deltaY, int deltaWidth, int deltaHeight)
    • calculateCorner

      public static int calculateCorner(Component c, int x, int y)
      Returns the corner that contains the point x,y, or -1 if the position doesn't match a corner.
    • getCursor

      public static int getCursor(int corner)
      Returns the Cursor to render for the specified corner. This returns 0 if the corner doesn't map to a valid Cursor
    • calculatePosition

      public static int calculatePosition(int spot, int width)
      Returns an integer indicating the position of spot in width. The return value will be: 0 if invalid input: '<' BORDER_DRAG_THICKNESS 1 if invalid input: '<' CORNER_DRAG_WIDTH 2 if >= CORNER_DRAG_WIDTH invalid input: '&'invalid input: '&'invalid input: '<' width - BORDER_DRAG_THICKNESS 3 if >= width - CORNER_DRAG_WIDTH 4 if >= width - BORDER_DRAG_THICKNESS 5 otherwise
