Log message:
2006-06-06 Roman Kennke <address@hidden>
PR 27920
* javax/swing/JTree.java
(JTree()): Initialize with default model.
(JTree(TreeModel)): Clear expanded state hashtable. Added
comment
on the updateUI() / setModel() order.
(setModel): Correctly (un-)setup the listeners. Clear the
expanded
paths.
* javax/swing/plaf/basic/BasicTreeUI.java
(BasicTreeUI()): Initialize listeners in installListeners().
(setModel): Complete editing on model change. Correctly resetup
the listeners. Update the layout cache accordingly.
(setShowRootHandles): Complete editing and update layout. Do not
call back into the JTree, this could cause cycles.
(prepareForUIInstall): Implemented. Moved some init code from
installUI() to this method.
(completeUIInstall): Implemented. Moved some init code from
installUI() to this method.
(createDefaultCellEditor): Check for type of renderer, and
install
with null renderer when not DefaultTreeCellRenderer.
(updateLayoutCacheExpandedNodes): Added null check for tree root
to avoid NPE.
(updateRenderer): Call updateEditor().
(installListeners): Initialize the listeners here. Added some
null
checks to avoid NPEs.
(installUI): Moved some init code to prepareForUIInstall() and
completeUIInstall().
(completeEditing): Return immediately if editing component is
null
or if the setting is to not stop editing on complete editing.
(checkForClickInExpandControl): Call handleExpandControlClick()
instead of toggleExpandState() directly.
(isLocationInExpandControl): Rewritten to correctly determine
the
expand click location.
(MouseHandler.mousePressed): Rewritten to make better use of the
instance methods of BasicTreeUI to handle the click.
(PropertyHandler.propertyChange): Handle model and cell renderer
updates.
* javax/swing/tree/DefaultTreeCellEditor.java
(DefaultTreeCellEditor): Removed initialization of the icon.
This
is done so that the constructor can deal with null renderer as
the
RI does. Maybe this needs more fixing.
* javax/swing/tree/TreePath.java
(isDescendant): Fixed this method. The previous version did too
much and compared the wrong things, which lead to a
ClassCastException
in equals().
* javax/swing/tree/VariableHeightLayoutCache.java
(update): Do nothing when model is null.
(setModel): Clear the tables and update the layout. Added null
check to prevent NPE.
