property view show reference [message #197110]

Hello,
I have several questions:
How to make the property view in the runtime not show the references
between classes?
Why some properties are changed as I make connections between
figures,while those containment property are not changed? For instance,two
classes A and B, A contains B,A also can be connected to B by another
class C.when I connect A and B with C,the property view show C in the
'incoming ' and 'outgoing' in A and B's property.but B's 'container' is A
is not shown in the property of B the moment I draw B in A?

Regards
Ye Liu

Hello Ye,

you can specify which properties should be shown and which not (and also
whether the visible properties should be editable) in the EMF genmodel
file. Select a property from the tree and change the 'property type' in
the 'edit' category. Here you can also assign categories to the several
properties (just like the 'ecore' and 'edit' categories in this sheet).
Make the changes and regenerate the edit code.

Regards,
Tobias

Hello,
Even if I changed the 'Property type' of this reference from'None' to
'Editable'.The outcome is still not as I expected.
e.g. a class O belong to class A, O has an association to A called
Parent.(in order to get the Parent name once an instance of O is drawn
inside an instance of A).Initially, when the 'Property type' of 'Parent'
is set to 'None' .Nothing was shown whether I draw instance of O inside A
or not.After I change the 'property type' to 'Editable', there 'parent'
property of O's instance shows a list of existing instances of A in the
Canvas.It is expected to show the specific parent automatically instead
let user to choose one from the list.

Thanks a lot!

Hi Ye,

actually, the current value of the reference should already be selected
in that list. Are you sure that the parent ref is the opposite of the
containing ref, so parent is set automatically when node O is inserted
in A? BTW, I would recommend not to set properties to 'editable' that
correspond to diagram elements, as they will most likely not synchronize
with the diagram when you change them.

Regarding your other posting I could also imagine that something is
wrong with your mapping model, especially the definition of the
compartment in A, so that O is not really contained in A, but only drawn
on top of it or something. Could you check your model file (using the
tree editor or as XML) and check whether O really is a child of A?

Hello,Tobias
First,thank you very much!
I have tried to define another class K(which is also a child of
container class A ) as compartment of A, and it succeed now.The 'parent'
property works well now as well as the collapsible function.
But I wonder if it is possible to add more figures inside the same
compartment?and how about include the an instance of the container itself?
Because when we define Compartment in .gmfgraph,there is only one 'Figure
Descriptor' can be chosen as property 'Figure'.(The container class A have
more than one children including itself. )

Long for your reply!

Hello Ye,

I think you got something wrong with you gmfgraph model. The compartment
figure ist NOT the figure of the node that is contained in this
compartment, but a container for those nodes.

For instance, in the general case you will have a figure with a label
and a compartment. That would mean you have a figure descriptor with a
child figure, which again has a child label and another child figure (a
rectangle).
- FigureDesc
- ParentFigure // this is the figure that is shown for the parent node
- LabelFigure // this figure is the label of the parent
- CompartmentFigure // this figure (should be a rectangle) is the
one associated with the Compartment

Now, in the mapping model, you define a top level node for the parent,
holding a compartment mapping associated with the compartment from the
gmfgraph model, a feature label mapping and a child reference mapping,
associated with the compartment mapping.

Well, I think this is a bit much to explain here. Have you yet tried the
GMF-Tutorials? I think they explain the issue very well. You find them here:
<http://wiki.eclipse.org/GMF_Documentation> (however, currently there
seem to be some problems with the server)

Hello,
I checked the tutorials carefully,and now I understand the real meaning
of compartment and its setting.
However, I still wonder whether the container class can contain itself
in the compartment.Or I should define them separately when I define the
Ecore model.E.g.there is such object A as a container for other
objects.The top A is the biggest container which there can be only one in
a program.Now I define only one class A,use an attribute Top to distinct
Top A and A.If it's better to define a separate class TopA and class A,A
is contained in TopA? Hopefully I'm understood.

Thank you very much!

Hello Ye,

I'm glad I could help. Concerning the problem of inserting A in A, you
should have a look at the thread "Indefinite Child Referentiation" right
next to this thread. Basically, you can insert nodes recursively by
setting the "Referenced Child" feature of a Child Reference.

Hello,
There is a bug in the generated method EditPart file:
xxxCompartmentEditPart.java
public String getCompartmentName() {
return Messages.NetworkCanalsObjectCompartmentEditPart_title;
}

it says Messages.NetworkCanalsObjectCompartmentEditPart_title cann't be
resolved.
I have checked all the places need refering the name of the compartment
and they are all written.I don't know where else is wrong?

Thanks

Hello Tobias,
I don't know if I understand correctly,I set the 'Referenced Child' of a
Child Reference to the container Node mapping.I couldn't tell whether it
works or not.
But I find one thing very strange: the compartment area is just a
limited rectangle area, it is not as big as the container's figure.So one
thing funny is if I draw a figure B inside the narrow compartment area of
A,then B's 'Parent ' property show A's name.if I draw B in the lower part
of figure of A,then B is not considered as A's child.
Is there a way to make the compartment area have the same size as the
figure contains it?

Thanks a lot!

Why can't you tell? Can you insert an A in an A (and another A in the A
in the A), or not?

There's definitely a way, but right now I can't tell how, because for me
it always worked by default, and by now I'm using exclusively custom
figures, so I can't just have a look in my gmfgraph. I think, you should
simply insert the label and the compartment figure into the parent
figure, without any layout, points, or stuff.

Hello,
Thanks a lot!Now every figure can be correctly added in the compartment
of container.Even though the compartment area is not eaqual to the area of
the container figure,I find ways to place the desired figure inside the
compartment.
