    • createMouseInputListener

      protected MouseInputListener createMouseInputListener()
      Creates the mouse listener for the JTableHeader.

      public static ComponentUI createUI(JComponent h)
      Returns a new instance of BasicTableHeaderUI.
      Parameters:
      h - a component.
      Returns:

    • installDefaults

      protected void installDefaults()
      Initializes JTableHeader properties such as font, foreground, and background. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.

    • installListeners

      protected void installListeners()
      Attaches listeners to the JTableHeader.

    • installKeyboardActions

      protected void installKeyboardActions()
      Register all keyboard actions on the JTableHeader.

    • uninstallDefaults

      protected void uninstallDefaults()
      Uninstalls default properties

    • uninstallListeners

      protected void uninstallListeners()
      Unregisters listeners.

    • uninstallKeyboardActions

      protected void uninstallKeyboardActions()
      Unregisters default key actions.

    • getRolloverColumn

      protected int getRolloverColumn()
      Returns the index of the column header over which the mouse currently is. When the mouse is not over the table header, -1 is returned.
      Returns:
      the index of the current rollover column
      Since:
      1.6

    • rolloverColumnUpdated

      protected void rolloverColumnUpdated(int oldColumn, int newColumn)
      This method gets called every time when a rollover column in the table header is updated. Every look and feel that supports a rollover effect in a table header should override this method and repaint the header.
      Parameters:
      oldColumn - the index of the previous rollover column or -1 if the mouse was not over a column
      newColumn - the index of the new rollover column or -1 if the mouse is not over a column
      Since:
      1.6

    • getBaseline

      public int getBaseline(JComponent c, int width, int height)
      Returns the baseline.
      Overrides:
      getBaseline in class ComponentUI
      Parameters:
      c - JComponent baseline is being requested for
      width - the width to get the baseline for
      height - the height to get the baseline for
      Returns:
      baseline or a value < 0 indicating there is no reasonable baseline
      Throws:
      NullPointerException - if c is null
      IllegalArgumentException - if width or height is < 0
      Since:
      1.6

    • getMinimumSize

      public Dimension getMinimumSize(JComponent c)
      Return the minimum size of the header. The minimum width is the sum of the minimum widths of each column (plus inter-cell spacing).
      Overrides:
      getMinimumSize in class ComponentUI
      Parameters:
      c - the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
      Returns:
      a Dimension object or null
      See Also:

    • getPreferredSize

      public Dimension getPreferredSize(JComponent c)
      Return the preferred size of the header. The preferred height is the maximum of the preferred heights of all of the components provided by the header renderers. The preferred width is the sum of the preferred widths of each column (plus inter-cell spacing).
      Overrides:
      getPreferredSize in class ComponentUI
      Parameters:
      c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
      Returns:
      a Dimension object containing given component's preferred size appropriate for the look and feel
      See Also:

    • getMaximumSize

      public Dimension getMaximumSize(JComponent c)
      Return the maximum size of the header. The maximum width is the sum of the maximum widths of each column (plus inter-cell spacing).
      Overrides:
      getMaximumSize in class ComponentUI
      Parameters:
      c - the component whose maximum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
      Returns:
      a Dimension object or null
