Hey,
I have added a Figure (Composite) to my Editor that contains other figures
and whose purpose is to group figures together.
When I add these Figures to my Composite they reduce in size so that more
can be fit in.
If I then remove them from the the Composite they return to normal size for
easy editing
What I would like to do is be able to open another editor from the
Composite.
So for example say the Composite contains 3 figures. If I then double-click
on it I want to open a new Editor which then shows these three figures at
normal size for editing purposes.
Anybody done this already or have ideas on how this can be done ?
Thanks,
Alan.

you should not be passing around or manipulating Composites or Figures.
You should be manipulating your models. The IEditorInput should
contain a light weight pointer to your model. It should not contain
the model itself. But to get you going quickly, you can just stuff the
model right into the IEditorInput based class you create.
In your editor, in the setEditorInput method or whatever its called, you
check with instanceof to see if its your type of IEditorInput and if so
you use it.
but again, a figure is just a way to show yoru model, but you should be
passing around and manipulating the model only.

CL,
Thanks for the advice. I created an instance of IEditorInput and had it hold
an instance of my model.
In the setEditorInput method of my new Editor I take this model and load the
parts of it I need into the new editor.
Not sure if this is how I should be doing it but I guess it'll do for the
time being.
Not quite sure what you are referring to when you speak about IEditorInput
containing a light weight pointer to my model.
Anyway I now have a new editor which displays the contents of my Composite.
What I was hoping to do now was to have changes that I make reflected back
in the original editor.
So if I add and a new Figure in my new Editor this should appear in the
Composite figure in the original editor on save.
This means that I somehow need to be able to update the original Model from
my new Editor.
Not sure how to approach this...would I be better off using a Multipage
Editor here or can I manage this another way ?
Thanks again,
Alan.

When the workbench is launched, the active page is null until after any open
editors have been created. I believe there's a bug open regarding this.
