[EMF Forms] Custom control get parent of an eStructuralFeature [message #1722675]

Hi guys,

I have an Ecore model that has the following structure:

BoolEnum
-> TRUE
-> FALSE

BoolStringValue
value -> BoolEnum

DifferentType1
boolStringValue -> BoolStringValue

DifferentType2
boolStringValue -> BoolStringValue

In my new custom control I want to be able to render differently the value combobox (from BoolStringValue). But how can I know its parent, from where it comes from (DifferentType1/DifferentType2)?

This is the skeleton for isApplicable method:

.... isApplicable(){

if (eStructuralFeature.getName().equals("value") && eStructuralFeature.getEContainingClass() == (EClass) pack.getEClassifier("BoolStringValue") && (condition??) )

{
return 10;
}

And which SWT control renderer should apply here to create the control? Should I use a BooleanControlSWTRenderer?

Thank you very much,
S.

Hi,

you can access the domain model with:
viewModelContext.getDomainModel();
and then you can do any check you want, e.g. for a specific parent.

Best regards

Jonas

Sorry, but this did not worked. From what I noticed, the viewModelContext.getDomainModel() gives information about the view model, but I can have multiple view models with different domain model references that are like this:

ViewModel1
X -> ... -> something -> BoolStringValueType -> value

ViewModel2
Y -> something -> BoolStringValueType -> value

ViewModel3
Z-> ... -> .... -> something -> BoolStringValueType -> value

I'm always interested in the class that contains a reference to this BoolStringValueType. (called "something" in the previous example)

Thank you,
S.

Hi,

what makes you believe that viewModelContext.getDomainModel() returns
something about the view model? Have you debugged that? What does it return?

best regards

Jonas

Hi,

I am sorry about that Embarrassed

, I found the eContents() and eAllContents() methods from the viewModelContext.getDomainModel(). I will use them.

Thank you,
S.
