A Windows L&F implementation of ListUI.
Inner Class Summary | |
class |
BasicListUI.FocusHandler
This inner class is marked "public" due to a compiler bug. |
class |
BasicListUI.ListDataHandler

class |
BasicListUI.ListSelectionHandler
The ListSelectionListener that's added to the JLists selection model at installUI time, and whenever the JList.selectionModel property changes. |
class |
BasicListUI.MouseInputHandler
Mouse input, and focus handling for JList. |
class |
BasicListUI.PropertyChangeHandler
The PropertyChangeListener that's added to the JList at installUI time. |

|
Method Summary | |
protected int |
convertRowToY(int row)
Return the JList relative Y coordinate of the origin of the specified row or -1 if row isn't valid. |
protected int |
convertYToRow(int y0)
Convert the JList relative coordinate to the row that contains it, based on the current layout. |
protected FocusListener |
createFocusListener()
|
protected ListDataListener |
createListDataListener()
Creates an instance of ListDataListener that's added to the JLists by model as needed. |
protected ListSelectionListener |
createListSelectionListener()
Creates an instance of ListSelectionHandler that's added to the JLists by selectionModel as needed. |
protected MouseInputListener |
createMouseInputListener()
Creates a delegate that implements MouseInputListener. |
protected PropertyChangeListener |
createPropertyChangeListener()
Creates an instance of PropertyChangeHandler that's added to the JList by installUI(). |
static ComponentUI |
createUI(JComponent list)
Returns a new instance of BasicListUI. |
Rectangle |
getCellBounds(JList list,
int index1,
int index2)
Returns the bounds of the specified item in JList coordinates, null if index isn't valid. |
Dimension |
getMaximumSize(JComponent c)
|
Dimension |
getMinimumSize(JComponent c)
|
Dimension |
getPreferredSize(JComponent c)
The preferredSize of a list is total height of the rows and the maximum width of the cells. |
protected int |
getRowHeight(int row)
Returns the height of the specified row based on the current layout. |
Point |
indexToLocation(JList list,
int index)
Returns the origin of the specified item in JList coordinates, null if index isn't valid. |
protected void |
installDefaults()
Initialize JList properties, e.g. |
protected void |
installKeyboardActions()
Register keyboard actions for the up and down arrow keys. |
protected void |
installListeners()
Create and install the listeners for the JList, its model, and its selectionModel. |
void |
installUI(JComponent c)
Initializes this.list by calling installDefaults() ,
installListeners() , and installKeyboardActions()
in order. |
int |
locationToIndex(JList list,
Point location)
Convert a point in JList coordinates to the index of the cell at that location. |
protected void |
maybeUpdateLayoutState()
If updateLayoutStateNeeded is non zero, call updateLayoutState() and reset updateLayoutStateNeeded. |
void |
paint(Graphics g,
JComponent c)
Paint the rows that intersect the Graphics objects clipRect. |
protected void |
paintCell(Graphics g,
int row,
Rectangle rowBounds,
ListCellRenderer cellRenderer,
ListModel dataModel,
ListSelectionModel selModel,
int leadIndex)
Paint one List cell: compute the relevant state, get the "rubber stamp" cell renderer component, and then use the CellRendererPane to paint it. |
protected void |
selectNextIndex()
Selected the previous row and force it to be visible. |
protected void |
selectPreviousIndex()
Selected the previous row and force it to be visible. |
protected void |
uninstallDefaults()
Set the JList properties that haven't been explicitly overriden to null. |
protected void |
uninstallKeyboardActions()
Unregister keyboard actions for the up and down arrow keys. |
protected void |
uninstallListeners()
Remove the listeners for the JList, its model, and its selectionModel. |
void |
uninstallUI(JComponent c)
Uninitializes this.list by calling uninstallListeners() ,
uninstallKeyboardActions() , and uninstallDefaults()
in order. |
protected void |
updateLayoutState()
Recompute the value of cellHeight or cellHeights based and cellWidth, based on the current font and the current values of fixedCellWidth, fixedCellHeight, and prototypeCellValue. |
