Hi,

I want to create for a GEF editor without modifying it an action which
can add a figure (for example a rectangle).

I don't want to add my action in the palette but if possible in a menu.
The figure created doesn't have to be persisted in the diagram file.

Is This kind of action is possible ? And how can i realize it ?
Regards

Alexia

You can certainly write an action that will just add a Figure without a
backing edit part or model. But then you will have to manage the state
of that figure yourself. Might be easier to use a model, but tweak
whatever serializes your model to not serialize that object. Perhaps
you would like to elaborate on the use case a bit?

Regarding the action itself, just read the platform developer guide on
how to put actions in menus. Then instantiate your action such that it
knows how to get a handle to the graphical viewer. The DeleteAction that
the Logic Example uses is one example of how to hook up a GEF type of
action.

Hope that helps
Ben

Hi,

I have many GEF editors and I want to add a generic action which permits
to add a figure which mustn't be add on the model, the diagram file.

HI !
i work in the same team as Alexia

Actually we have a plugin which works with some Gef editors : GMF ...

we want to add a menu which permit to add a rectangle on any diagram
working for our plugin.

We have some possibilites :
1) designing a top level generic plugin which only works with gef
possibilites
2) designing a plugin with specific editor capacities

in both way we don't know how to add dynamically a figure which is not
expected by current editor

if somebody has a solution it could be a pleasure :)

Regards

Tristan FAURE
