EmfComboboxDataBinding

public EmfComboboxDataBinding()

Method Details

feature

public EmfComboboxDataBinding<T,V> feature(org.eclipse.emf.ecore.EStructuralFeature feature)

Sets the EMF structural feature to bind to the combo box. Configures automatic value extraction and command-based updates.

Parameters:

feature - The EMF structural feature to bind

Returns:

this binding instance for method chaining

nameFeature

public EmfComboboxDataBinding<T,V> nameFeature(org.eclipse.emf.ecore.EStructuralFeature nameFeature)

Sets the EMF feature to use for displaying item labels.

Parameters:

nameFeature - The EMF feature containing display names

Returns:

this binding instance for method chaining

getLabelProvider

protected org.eclipse.jface.viewers.IBaseLabelProvider getLabelProvider()

Creates an appropriate label provider based on configuration. If nameFeature is specified, creates an ObservableMapLabelProvider that automatically updates when feature values change.

Overrides:

getLabelProvider in class ContainerComboboxDataBinding<T extends org.eclipse.emf.ecore.EObject,V>

Returns:

Configured label provider instance

createBinding

public void createBinding()

Description copied from interface: AbstractDataBinding

Creates and initializes the data binding.

Specified by:

createBinding in interface AbstractDataBinding<T extends org.eclipse.emf.ecore.EObject>

Overrides:

createBinding in class ContainerComboboxDataBinding<T extends org.eclipse.emf.ecore.EObject,V>

getFeature

public org.eclipse.emf.ecore.EStructuralFeature getFeature()

Description copied from interface: EmfDataBinding

Gets the EMF structural feature being bound.

Specified by:

getFeature in interface EmfDataBinding<T extends org.eclipse.emf.ecore.EObject,V>

Returns:

The EStructuralFeature representing the model attribute being bound to the UI control. This defines which property of the EObject container is being observed/modified.
