SETTING-UP the EDITOR Models by code [message #1053741]

Hi Everyone,
I am realizing a graphical editor with Eclipse GMF.
- First of all I defined an ecore metamodel to describe my editor
- In my ecore metamodel there is an EClass called Block. Since the user can define different blocks to have into the palette that reflect Block definition, I would like to implement a set up phase where he can decide which and how many to have, before starting up the editor and its components. (note: It is not possible to know a priori how many of them he will have and he can also change their properties and number during the normal execution of the program, so for example, he can create a new element of that block and it has to be visible into the palette).

Is it possible to define the .gmfgraph, .gmftool and the others by code without using the GMF Dashboard ?

I hope to have well defined the problem,
Thank you very much in advance.

Best regards,
Luca.

Hi Luca,

you can completely program using GMF runtime without using GMF Tooling. It could be however be very useful to define a basic set of your language using the GMF models and manipulate the generated elements (figures, palettes etc.) at runtime. That is what works quite well in my case.

Thank you very much Ralph for your suggestions.

I am a very beginner with GMF so I am reading tutorials and documentations about it, but I cannot find the one that can really help me.
Since I am using Eclipse Juno I searched here http://help.eclipse.org/juno/index.jsp
but I didn't find any specification.

Can you recommend me where I can find the right documentation for Eclipse Juno ?

Thanks,
Luca.

Hi,

here you will find documentation on GMF Runtime http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.gmf.doc/reference/api/runtime/overview-summary.html . You should also take a look on the examples and code snippets in the GMF wiki.

Hi Ralph,
thank you very much for all suggestions,

I was able to create dinamically into the palette the number of objects I needed from a single ecore class so they refer just to one metamodel class definition.
I this time I would like to get their properties from the palette to draw on the editor but the only thing I can do it is getting the type of class.
It would be nice for me to get for example their name to be set already into the objects at the moment of their instantiation.

How can I get also some other properties they have ?
For example, these NodeTools into the palette have different names, how can I know them at the moment of block creation on the editor? It seems like there is no connection between palette and commands.

Can you help me ?

Best regards,
Luca.

Hi,

you can access the palette in your command via the editing domain and ask for the active tool.

Hi Ralph, thanks for replying me.
I am trying to follow your advice from the method doExecuteWithResult of an EditElementCommand but I am not able to do as you suggested me.

Can you please give more detail how to access to the getActiveTool I guess?

Thanks,
Luca

Hi,

here is code that I placed in canExecute. This is code that I place in a create command https://github.com/deep-modeling/melanee-core/blob/master/plugins/org.melanee.core.models.gmf/templates/aspects/xpt/diagram/commands/CreateNodeCommand.xpt . I also do use it in ElementInitializer (line 104) https://github.com/deep-modeling/melanee-core/blob/master/plugins/org.melanee.core.models.gmf/templates/aspects/xpt/providers/ElementInitializers.xpt . It is important that you https://github.com/deep-modeling/melanee-core/blob/master/plugins/org.melanee.core.models.gmf/templates/aspects/xpt/editor/Editor.xpt (line 81) show how to get a palette from an editing domain. It is important to know that this is done on a DefaultEditDomain so may need to do a type cast when retrieving you edit domain from somewhere else than the generated xxxDiagramEditor.
