Constructs a new ListUI.
getCellBounds
public abstract Rectangle getCellBounds(JList list,
int index1,
int index2) Determines the bounding box of the rectangle spanned by
two list indices.
list - the JList for which this delegate object
provides the pluggable user interface.index1 - the zero-based index of the first cell.index2 - the zero-based index of the second cell.
- the spanned rectangle, or
null if either
index1 or index2 does not
designate a valid cell.
indexToLocation
public abstract Point indexToLocation(JList list,
int index) Determines the location of the specified cell.
list - the JList for which this delegate object
provides the pluggable user interface.index - the zero-based index of the cell whose location shall be
determined.
- the position of the top left corner of the cell in the
JList coordinate system, or null
if cell does not designate a valid cell.
locationToIndex
public abstract int locationToIndex(JList list,
Point location) Determines the cell index which is the closest to the specified
location. The find out whether the returned cell actually
contains the location, the caller should also use
getCellBounds(JList,int,int).
list - the JList for which this delegate object
provides the pluggable user interface.location - a point in the JList coordinate
system.
- the index of the closest cell, or -1 if the list model
is empty.
