Hi:
I'm using the GEF drop from Feb. 13, 2003. I was wondering if it is
possible to place the palette back on the left side of the editor rather
than the right side.
Thanks,
Jason

It seems like I can move the palette back to the left by simply switching
the order with which the GraphicalViewer and PaletteViewer are added to the
Splitter in the GraphicalEditorWithPalette:createPartControl.
thanks anyway,
Jason

Should I assume then that the intended starting point for a commercial
quality editor which uses GEF is to simply subclass EditorPart?
And is it possible to concisely state (for a GEF newbie) why it is
better to start out by subclassing EditorPart as opposed to
GraphicalEditor (i.e. does something in GraphicalEditor not scale, etc)?
(Or is it perhaps merely historical accident and not some limitation of
GraphicalEditor that none of those Websphere tools you mentioned inherit
from GraphicalEditor--maybe they were started before GraphicalEditor
existed, perhaps?)

Since this was written a couple months ago, has there been any decision
on whether the palette is indeed going to become a view for 2.2? And if
so, is there any estimate on which of the 2.2 release milestones this
would be slated for?
Also (another newbie question--I apologize) is there any way to wrap the
2.1 palette in a view? (I would like the palette to go in a tab where
the Navigator is, for example, so I was hoping to make a view and
somehow put the palette in it. But I haven't read enough of the code
yet to know if this is possible, or how I would access the palette to
add it...)
Thanks in advance,
Peter Armstrong

These is lot's of crap that you have to do to be a well behaved editor. We
don't do any of it for you. You must respond to your input being renamed,
deleted, or moved. You must respond to different versions being loaded and
replacing the current contents. You must support validate-edit, for
pessimistic team environments.
Also, there is lots of stuff we do that maybe you don't want to do. For
example, Action management, or synchronizing the selection between the
outline and editor.
Also, you might want to inherit from MultiPageEditor, or write your own
multipage implementation, or maybe you want a split pane editor. Therefore,
we try to make sure that the interesting stuff in GEF is not burried in our
editor implementation.
If there is interesting code in our editor, maybe it can be factored out?
