Create a dynamic custom control [message #1263292]

Hi,

i want to create a custom control, without specificing a "hardcoded" references within the getNeededDomainModelReferences() as it is documented in the CustomControls Tutorial Section.
In the tutorial, a VFeaturePathDomainModelReference is created for "User_LastName" and "User_Gender".

For my custom control, i want to set this VFeaturePathDomainModelReference's based on the current selection within the TreeNavigator.
So is there any api in ECP 1.2 where i can get the currently selected DomainObject?

The API from ECP 1.1 org.eclipse.emf.ecp.edit.spi.ECPAbstractControl#ECPControlContext getModelElementContext().getModelElement() was removed in ECP 1.2, as i can see here.
Also, ECPAbsractControl.getViewModelContext().getDomainModel() is not initialized at this point

Thanks in advance Smile

Hi Bryan,

Thank you for your message.

A custom control based on the current selection will most probably be implemented without any dependencies on the actual selection. This would be something like the BooleanControl. It just doesn't care what you select, the tester provided by the control just ensures, that the attribute which is about to be shown is of a specific type.

If you want to create a custom control which has domain specific behavior, then you will need to know the actual selected object which was selected. This is ensured by the tester of the custom control.

I might be wrong Wink

, but are you maybe trying to implement some kind of a master detail view, you might want to look at the TreeMasterDetail model.

Maybe you could provide some more detail to your usecase, so I can give you better advice.

Cheers,
Eugen
