[platform-ui-dev] Dialogs remembering their size and position

[Susan M Franklin <susan_franklin@xxxxxxxxxx>]

The JFace Dialog class now supports
(in builds >20051004) persisting of a dialog's location and/or 
size.  For a detailed history of
this topic and explanation of how to get this behavior,
see https://bugs.eclipse.org/bugs/show_bug.cgi?id=33550.

Dialog owners are encouraged to migrate
to the new behavior and delete any 
code previously used to persist size
and location.  (Then all those pesky 
multi-monitor bugs won't be your fault
anymore!).  It is still up to you to determine 
whether persisting location and/or size
makes sense for your particular dialog.  
You won't magically get any behavior
without doing something.  

Here's how it works.

(1)  Override the method Dialog.getDialogsBoundsSettings()
to return the 
IDialogSettings appropriate for persisting
your dialog's bounds.  

(2)  If you want to persist the
last known size and location of the dialog, 
you are done.  If you want to persist
only the size or only the location, 
override the method Dialog.getDialogBoundsStrategy()
to return the constant 
indicating what strategy to use.  This
is a combination of bit mask values which are 
currently defined as
  DIALOG.PERSIST_LOCATION - persist
the last known location of the dialog
  DIALOG.PERSIST_SIZE - persist
the last known size of the dialog

If you think a certain dialog should
have its size and/or location persisted,
please open a bug for that dialog.
