[cp-patches] scrollable JList

[Roman Kennke]

Hi,

please review the attached patch that improves the behaviour of JList
within a scrolling container, especially with layoutOrientation set to
JList.HORIZONTAL_WRAP or VERTICAL_WRAP. Is the ChangeLog entry ok?

        * javax/swing/JList.java
        (getPreferredScrollableViewportSize):
        previous implementation was merely guessing the size,
        now it respects layoutOrientation, visibleRowCount
        and preferredSize
        (getScrollableTracksViewportHeight):
        reimplemented to respect layoutOrientation, visibleRowCount
        and preferred size
        (getScrollableTracksViewportWidth):
        reimplemented to respect layoutOrientation, visibleRowCount
        and preferred size
        * javax/swing/plaf/basic/BasicListUI.java
        (getPreferredSize):
        improved calculation of preferredSize when JList is
        set to HORIZONTAL_WRAP or VERTICAL_WRAP.
        (getCellBounds):
        previous implementation assumed a layoutOrientation of
        JList.VERTICAL, now also ok with JList.HORIZONTAL_WRAP and
        JList.VERTICAL_WRAP
