How to use a EditorPart to draw Draw2D figures on it ? [message #230965]

Hi!

I going to create a eclipse plugin containing a graphical editor
(EditorPart) .
I'm not sure that I can use the GEF existing editor so I decided to
implement my own.
I extend the abstract class EditorPart and plant to use a Canvas to draw
the graphics with Draw2D.
My problem is that I can't find how a EditorPart exactly works. Where
must I create the Canvas object I am going to draw at and which methodes
are called from eclipse system to draw the canvas content ?

Is there a tutorial which can help me or can someone explain how the
editor works generaly ?

thanks, Jan

Hi,

Did you look at this tutorial:
http://eclipsewiki.editme.com/GefDescription ?
Maybe you could find some useful information there.

Yes I had a look at that.

I'm not sure if I can use it that way. Maybe I have to create my own
editor extending EditorPart class. And how this exactly works I can't
find until now.

The problem is that the graphical editor I am going to create musst be
able to customise its tool-window at runtime with tools created with the
editor itself.
If someone can tell me if the GEF existing framework is able to do that
I didn't have to understand the EditorPart class because I can extend
one of the GEF existing graphical editors as descriped in some tutorial
I found.

regards, Jan

Hi there,

I have somewhat the same Problem, so I didn't want to open up a new thread, although this one is pretty old.

I would be thankful for some hints/tips/links on how to work with the EditorPart and where to create the Canvas. I need to draw some 3D-Objects in the Editor using JOGL (later on also some other bindings, for evaluation purposes) and therefore need to get a canvas in the editor.

Thanks in advance,

Dimi
