public abstract java.awt.Rectangle getCellBounds(javax.swing.JList list, int index1, int index2)
Returns the bounds of the specified item in JList coordinates, null if index isn't valid.
param
index The index of the JList cell.
return
The bounds of the index'th cell.
public abstract java.awt.Point indexToLocation(javax.swing.JList list, int index)
Returns the origin of the specified item in JList coordinates, null if index isn't valid.
param
index The index of the JList cell.
return
The origin of the index'th cell.
public abstract int locationToIndex(javax.swing.JList list, java.awt.Point location)
Convert a point in JList coordinates to the closest index of the cell at that location. To determine if the cell actually contains the specified location use a combination of this method and getCellBounds. Returns -1 if the model is empty.
param
location The JList relative coordinates of the cell
return
The index of the cell at location, or -1.
