Custom Property Sorter in EMF Editor

The default property sheet provided by EMF sorts the attributes in Alphabetical Order, no matter what is the actual order of definition in the ecore. However EMF uses the generator GAP pattern, so one can change the generated code and mark such API as @generated NOT. So no mess up during regeneration

1. Implement a Custom Sorter

package com.odcgroup.edge.t24ui.common.presentation;

import org.eclipse.ui.views.properties.IPropertySheetEntry;

import org.eclipse.ui.views.properties.PropertySheetSorter;

public class CustomPropertySheetSorter extends PropertySheetSorter {

    @Override

    public void sort(IPropertySheetEntry[] entries) {

        // do nothing;

        // or may be your custom logic

    }

}

2. Implement a CustomPropertSheetPage

which sets the newly implemented sorter. In simple just replace the getPropertySheetPage() method in the generated Editor (ex : YourEditor.java) by the snippet below

    /**

     * This accesses a cached version of the property sheet.

     * <!-- begin-user-doc -->

     * <!-- end-user-doc -->

     * @generated NOT

     */

    public IPropertySheetPage getPropertySheetPage() {

       

        class MyCustomPropertySheetPage extends ExtendedPropertySheetPage {

            /**

             * @param editingDomain

             */

            public MyCustomPropertySheetPage(AdapterFactoryEditingDomain editingDomain) {

                super(editingDomain);

                setSorter(new CustomPropertySheetSorter());

            }

           

            @Override

            public void setSelectionToViewer(List<?> selection) {

                YourEditor.this.setSelectionToViewer(selection);

                YourEditor.this.setFocus();

            }

            @Override

            public void setActionBars(IActionBars actionBars) {

                super.setActionBars(actionBars);

                getActionBarContributor().shareGlobalActions(this, actionBars);

            }

        }

        PropertySheetPage propertySheetPage = new MyCustomPropertySheetPage(editingDomain);

        propertySheetPage.setPropertySourceProvider(new AdapterFactoryContentProvider(adapterFactory));

        propertySheetPages.add(propertySheetPage);

        return propertySheetPage;

    }
