[EMF Client Platform] ViewModel adding children references [message #1177407] Sat, 09 November 2013 00:17 Go to next message
Eclipse UserFriend
With the ViewModel I would like to consolidate controls for an elements
children in the Editor for the parent element. I see this is possible
for 0..1 and 1..1 references and have experimented with it by adding
controls for children inside of layouts and groups.



Read the 'How to customize the editor layout' article but still have
many questions about how to use some of the models elements like the
Span, GroupGrid, ShowRule, EnableRule, TableControl and How to add x..n
references?

thanks for any help,
John

Hi John,
as it happens, I am currently working on a more detailed tutorial. I
hope I will be able to publish the first version of it today. I hope it
answers most of your questions. I will post a link as soon as it is
published.

Best Regards

Jonas

While still writing on the tutorial, one question:
You mentioned x..n references, could you explain me a little bit more in
detail, what you want to do?

Best Regards

As an example I have an EObject named Premises that has a couple of
attributes name and id. The premises contains an EReference named
Address (1..1) that has attributes and may contain (0..1) a GeoPoint
with lat/long attributes. The Premises contains one or more people
EReferences that may contain a phone number. The Premises may also
contain one or more Program Status (0..*).

When the Premises is selected I would like the editor to show all its
children references. Now I am not clear on how that will work in the
for the child portion of the UI if there are no children. (I suspect
this is where the logic 'ShowRule' comes in?) How are multiple children
modeled in the UI with the TableControl??

Also not clear if the Editor UI on its own can create or delete children
or does one explicitly have to use the Model Explorer for creation and
deletion?

Also the question comes up regarding modeling an EObject in a ModelView
and how the Editor reacts if that modeled EObject is a child of another
EObject that is modeled and referencing the first modeled EObject. In
other words if I create a ViewModel for an EObject do I have to recreate
the same modeled portion of that child EObject if I want to see it
contained in parent?

best regards,
John

Hi,

from an ECP point of view, containment attributes are typically handled
differently depending on their multiplicity.

References with a mutliplicity of more then 1 are per default displayed
in a list of hyperlinks. Alternativly, you can specify a table control
to display the children "inline". I have documented this:

http://eclipsesource.com/blogs/tutorials/emf-forms-view-model-elements/#tablecontrol

For 0..1 references, ECP currently assumes, that the attributes of the
referenced object logically belongs to the parent. The adress is a good
example. From the user point of view, you might want to hide, that
adress is an own object. The user probably expects to enter the adress
of a premise in the same form. This can be done by placing controls on
the view of the premise, which reference attributes of the object
adress. The view model editor allows to select attributes of child
elements, too. Of course you might want to group all attributes of a
child object in the UI.
If you reference a child object in the view model, ECP will create an
empty object, if you open a premise without an adress, the adress will
be created. Does this match your requirements? Or shall the user
explicitly create a child object, e.g. a GeoPoint?

Regards

Jonas

That's very functioal.

Do you mean hide it in the the hierarchy of the Model Explorer?
How is this done? GenModel?

Yes, I have done this and it works well.

Well the Premises must have an address, so if a Premises is created, and
the UI has been defined for the address it makes sense if the Address is
created, but an address may not have a GeoPoint, so the user should be
allowed to explicitly create or Not create it.

Hi Jonas,

I tried to create a tableControl, but have not had any luck with my
model or with the 'Task' model of your example. Here is what my
viewModel userGroup.view looks like:

<org.eclipse.emf.ecp.view.model:View xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:org.eclipse.emf.ecp.view.model="http://org/eclipse/emf/ecp/view/model"
xmlns:org.eclipse.emf.ecp.view.table.model="http://org/eclipse/emf/ecp/view/table/model"
name="UserGroup">
<rootEClass
href="http://eclipsesource.com/makeithappen/model/task#//UserGroup"/>
<children
xsi:type="org.eclipse.emf.ecp.view.table.model:TableControl"
name="UserGroup" addRemoveDisabled="true">
<domainModelReference
xsi:type="org.eclipse.emf.ecp.view.table.model:TableDomainModelReference">
<domainModelEFeature xsi:type="ecore:EReference"
href="http://eclipsesource.com/makeithappen/model/task#//UserGroup/users"/>
</domainModelReference>
<columns>
<attribute
href="http://eclipsesource.com/makeithappen/model/task#//User/firstName"/>
</columns>
</children>
</org.eclipse.emf.ecp.view.model:View>

The plugin.xml of the com.eclipsesource.makeithappen.ui looks like:

<extension
point="org.eclipse.emf.ecp.view.model.provider.xmi.file">
<file
filePath="viewModel/taskView2.view">
</file>
<file
filePath="viewModel/userGroup.view">
</file>
</extension>

BTW - I am also getting parsing errors if I try to use the
viewModel/taskView.view viewModel from the example (right from git) so
I had to redefine it.

Any ideas what I am doing wrong?
thanks,

John

I see. We did not have this requirement before, so we would need to
develop a new control for a 0..1 reference. That means you could
consider a contribution or a sponsorship. Is one of these possibilities
an option for you?

Yes, I would be happy to contribute, but of course will have to dig
deeper and learn the internals first, before I could be of any help.

Hi,

we were able to reproduce the first issue, there is a minor bug in the
1.1.0 release, we will create a hotfix for this asap:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=421709

About the taskView.view: Where did you get this file from exactly? I
browsed the make it happen repository and I couldn't find it.

Thanks for the detailed report!

Kind regards

Jonas

Hi Jonas,

Good to here you could reproduce this problem.

The file is in the ui plugin. Here is the link to the file:
https://raw.github.com/eclipsesource/makeithappen/master/com.eclipsesource.makeithappen.ui/viewModel/taskView.view


thanks,
John

Hi Jonas,

1.1.1 is working for me. I was able to create table controls for
children of parent EObjects. Did notice a couple of limitations:

1. If the children have attributes that are enumerations the
TableControl column only shows a text type control vs a drop down menu.
Is this a current limitation or can I configure something to get a drop
down with all the enumerations? Of course for now I can just use the
model explorer to configure these values.


2. A child displayed in the TableControl may also be a parent of
optional objects, Will the table control eventually be able to handle
children of its own in columns?

What may be a simple solution for these more complicated types inside a
tableControl is to allow the tableView modeler to display links to these
objects, which would then visualize in their own editor showing either a
customized view or a default one.

thanks again for all your work,
John

Hi John,
sorry for the late answer, I have overseen this second post, the thread
is pretty long right now :-)

There is currently no drop down, could you please file a feature request
in Bugzilla?

The question is how this should look like. Would you espect to unfold
the entry then? If so, we would probably need to use a more powerful
table, e.g. NATtable

You should be able to double click an element in the table to open it up
in a new editor. Is this what you meant?

Best Regards

Jonas
