hi
i'm trying to develop a simple rcp application.
i just have a perspective with two views
now i want to add an editor with a palette
(GraphicalEditorWithFlyoutPalette), but i don't want the editor to do
anything. i just want to show the editor opened when my application starts.
i have already search the web looking for examples, articles, snippets,
...anything that could help me, but i'm getting crazy with this!
is it possible to have an editor without a model and all stuff? just an
empty white area with a palette?
when and how should i open the editor? (i have already read the post "open
editor automatically" but i still don't understand...)
i tried page.openEditor(...) in my WorkbenchAdvisor.postWindowOpen() but
the editor's place appears the message "An error has occurred when
creating this editor". After debugging source i noticed that
graphicalViewer is null
any help would be very appreciated
TIA
Tom

Try creating an empty logic diagram. That's what you want it to look like,
right? The point being that you can still have a model, without having a
file behind it. The model (LogicDiagram) is there, but it has no children.
So, to answer your question, yes, it's possible. Look at an EditorPart's
setInput() method. The logic example expects a IFileEditorInput. Since,
there's no file for what you want to do, you'll probably have to write your
own IEditorInput subclass. Or you can just create an empty model yourself
in the editor.
What are you trying to do? Do you want like a default, untitled editor to
be created when the workbench is launched? In that case, you could possibly
also create like a temp, hidden file somewhere and use it as input. Save
then, would have to work as save as.
As for launching the editor when the workbench is launched, I'm not sure.
The folks over at eclipse.platform newsgroup might be able to better help
you with that.

thanks for your help.
i have found a .pdf in ibm.com/redbooks ("Eclipse Development using the
Graphical Editing Framework and the Eclipse Modeling Framework") and i'm
trying to use some parts of the code
i have already created the editor without any problem, but my code fails
when i try to add a PaletteViewer. The problem is that PaletteViewer uses
DefaultPaletteViewerPreferences which in turn uses GEFPlugin. I don' t
know what's this GEFPlugin. I'm constructing an RCP app, i have my class
that extends AbstractUIPlugin...what am i missing?
i'm using GEF 3.1.0
TIA
