Hi,

what i want to do is to replace a figure (for example a rectangle) with a self-made GUI (with radio buttons, checkboxes and more).

When the user drag&drops an element from the palette toolbar I want a little GUI to appear in the editor field.

thanks
Mahmoud

I guess this would be rather difficult, as the Canvas uses Draw2D, which
is a lightweight drawing toolkit. It does not support embedding SWT
widgets into the canvas.

However, you could have look at org.eclipse.draw2d.Clickable and its
subclasses. There are some Draw2D Figures that can be used in the Draw2D
Canvas and are lightweight implementations of Buttons. However, there is
not very much different stuff available.

An alternative would be to use a hover-Editor that shows in front of the
Draw2D canvas and can contain any SWT stuff you want. But I'm not
familiar with that.

Hi Mahmoud,

> - what the object that is used in gef reffering to a cavas?

You should have a look at the Draw2D documentation:
http://help.eclipse.org/helios/topic/org.eclipse.draw2d.doc. isv/guide/overview.html

From that I understand a "LightweightSystem" is the top-level class
that can contain a Canvas. I think you can also use such Lightweight
System yourself as an Widget in any arbitrary SWT Components.

Sorry, I don't know how to do that. I guess you cannot use the GMF code
directly to do that, but you could use your own Multipage Editor and
there embed the generated GMF Viewer as one Tab. I think the MDT/Papyrus
Editor does it that way. You could have a look at that or directly ask
the Papyrus guys how they did it.
