Hello guys,

I succeeded in making a functional ecore model from my XSD file, but now I have a problem related to control labels.

I have the following situation:

XSD:
<xs:complexType name="bool_string_valueType">
<xs:attribute name="type" type="xs:string" fixed="EUTILstringValue"/>
<xs:attribute name="value" type="boolStringEnum" default="FALSE"/>
</xs:complexType>

<xs:complexType name="auto_commitType">
<xs:sequence>
<xs:element type="bool_string_valueType" name="bool_string_value"/>
</xs:sequence>
<xs:attribute type="xs:string" name="type" fixed="EUTILparameter"/>
<xs:attribute type="xs:string" name="name" fixed="auto_commit"/>
<xs:attribute type="xs:string" name="valueType" fixed="str"/>
</xs:complexType>

<xs:complexType name="use_degradedType">
<xs:sequence>
<xs:element type="bool_string_valueType" name="bool_string_value"/>
</xs:sequence>
<xs:attribute type="xs:string" name="type" fixed="EUTILparameter"/>
<xs:attribute type="xs:string" name="name" fixed="use_degraded_mode"/>
<xs:attribute type="xs:string" name="valueType" fixed="str"/>
</xs:complexType>

XMI:
<autoCommit
name="auto_commit"
type="EUTILparameter"
valueType="str">
<boolStringValue
value="TRUE"
type="EUTILstringValue"/>
</autoCommit>

<useDegraded
name="use_degraded_mode"
type="EUTILparameter"
valueType="str">
<boolStringValue
value="TRUE"
type="EUTILstringValue"/>
</useDegraded>

In a new view model I want to add both values of the boolStringValue (the auto_commit and use_degraded ones), but then it will display two drop-downs having the same label called "Value". How can I change this depending on the parent somehow, without making another bool string value type?

Thank you very much,
Simona T.

What do you mean by "the view model"? Is this a question about EMF Forms?

Sorry, I meant to say view, not view model. The view model is the project created in IDE.

I'm trying to figure out what you mean by "view model". Is this an EMF
Forms question?

The EMF Forms developers monitor the eclipse.technology.emft forum and
generally expect the subject line to be prefixed with [EMF Forms]. They
might not notice your post here or without that prefix.

Hi Simona,

I am not sure, if I understand your requirement. Could you add a
screenshot or a drawing?

Best regards

Hello Jonas,

Sorry for not being able to explain (I am an EMF beginner), it is more simpler than it looks maybe.

The first photo attached (Part_of_ecore.png) shows how the three complex types from the XSD (autoCommit, useDegraded, boolStringValue) + 1 enum (BoolStringEnum) are generated in the ecore. The AutoCommitType and UseDegradedType both have the same EAttribute boolStringValue of type BoolStringValueType. The BoolStringValueType has also an EAttribute called "Value".

Now, I want to be able to create a view with both boolean values (that means both the AutoCommit->boolStringValue->value and the UseDegraded->boolStringValue->value), but not with the default label "Value".
I attached a second photo in which you can see how the controls are generated in the view and how I want them to be.

Please tell me if it is clear now, if not, I will try to explain better. Any help is appreciated.

Thank you very much for your time!
Simona

Hi,

have you tried to set the Label Alihment to "none" in the view model for
these controls?

Best regards

If I do that, then the label "Value" disappears. Then, I can manually create in the view an Horizontal Layout and a label component with name "Auto commit" indeed. But this is the only way?

There isn't any other programmatic way in which I can obtain this? To have access to the source code and modify the implementation of this label to take into account the parent in which BoolStringType is in? Usually I saw that this labels are changed through plugin.properties file from the edit plugin. I also saw that you can modify the label in the model explorer by changing the implementation in getText(Object object) method from the ItemProvider.

Anyway, thank you very much for the solution!

Hi,

the problem with the two approaches you describe is that the label
depends on the type of the parent, which is a very special case. That is
why plugin.properties will not work. Labels are provided by a service in
EMF Forms, which needs to be registered as an OSGi service. The default
is this:
org.eclipse.emfforms.internal.core.services.label.EMFFormsLabelProviderImpl

You can register a custom implementation with a higher service rank to
replace the default behavior.

Best regards

Jonas

Hi again Jonas,

I came back to this topic recently. Now, I want to create a custom control with a configurable label instead of creating an OSGI service. Custom controls will help me more in the future.
I have some questions:

1) How can I take the parent of the parent of the parent in isApplicable method?
if (eStructuralFeature.getName().equals("value") && eStructuralFeature.getEContainingClass() == (EEnum) pack.getEClassifier("BoolStringEnum")) && parentofBoolStringEnum is BoolStringValueType && parentofBoolStringValueType is AutoCommitType)
{
return 10;
}
2) think I should use a combobox swt control renderer to create the control? Which one should apply in this case?
3) Is it ok if I add new annotations in Ecore model to mark the objects where this custom control should apply? But then when a user clicks to see a view, the custom control would look in all models to read the elements with a certain annotation? I believe it puts an overload on the application, right?

Thank you very much,
S.
