im very new the world of GEF, and i'm presently battling to fully
understand the design of the GEF.
the issuse that im now facing is very simple....
all i have to do is drag and drop a Person(model) on to the editor.
this is my conclusion of the steps needed to implement
1)write the model(PersonModel)
2)figure...where we do drawing of the figure(PersonFigure)
3)edit part ...we cal createFigure and refreshVisuals()(PersonEditPart)
4)editpartfactory
5)command... for actually executing the request

i want get the advice and nod of the expert whether my understanding is
correct or it needs correction.

best regards
vedgunjan

Right, and then you just need to tie them all together. That is the
intended parent EditPart should be returning the CreateCommand from its
LayoutEditPolicy, the new EditPart should listen to the model, etc. I am
assuming you already have the palette item for the Person.

Just try it out, and post back here if you run into problems.

hi,

you are totally right. These are important steps. Have you read the
documentation at:
http://www.eclipse.org/gef/reference/articles.html?cvsroot=T ools_Project

There you can find a lot of documentation how get started with GEF. As I
remember there is also an article about drag 'n drop. Read it, if there are
still questions than post to this newsgroup.

many regards

Andreas
