MetalFileChooserUI is pretty much completed now. I am still testing it
for any remaining bugs. The sizing is still off in some cases, since the
bug for wrapping JLists is not fixed (the wrapping code is temporarily
commented out).
The details view works. Editing in all views also works.
2005-11-29 Lillian Angel <[EMAIL PROTECTED]>
* javax/swing/JViewport.java
(setView): Added check to prevent NPE.
* javax/swing/plaf/basic/BasicFileChooserUI.java
(ListLabelRenderer): Removed class, never used.
* javax/swing/plaf/metal/MetalFileChooserUI.java
(DetailTableModel): Removed, not needed.
(TableFileRenderer): Implemented to override some color
and icon defaults in the default table renderer.
(actionPerformed): Set selection in list, if something was
selected in the table.
(actionPerformed): Set selection in table, if something was
selected in the list.
(propertyChange): Added code to set the selection for the table,
as well as the list. This depends on what view we are in.
(editFile): Fixed to call scrollRectToVisible instead.
(TableClickListener): Implemented new private class to take
care of double clicking (changing/opening directories/files)
and single clicking (editing).
(TableClickListener.mouseClicked): Implemented
(TableClickListener.editFile): Implemented
(TableClickListener.completeEditing): Implemented
(TableClickListener.EditingActionListener): Implemented
(TableClickListener.closeDialog): Implemented
(installListeners): Added code to initialize listener fields.
(uninstallListeners): Added code to uninstall all listeners.
(createList): Changed to use scrollPane field.
(createDetailsView): Changed to use updateTable function. Set
some characteristics for the table: column selection, renderer,
listener etc.
(updateTable): Implemented to changed/add/remove rows from the
table, as needed.
(removeControlButtons): Added repaint, revalidate calls.
(ensureFileIsVisible): Removed. Does the same thing as super.
(rescanCurrentDirectory): Added check for different views.
(setDirectorySelected): Removed. Does the same thing as super.
(getDirectoryName): Removed. Does the same thing as super.
(setDirectoryName): Removed. Does the same thing as super.
(valueChanged): Changed comment.
