Forms

Fair enough…

Bummer! A new OSGi header!

What do you expect from an editor?
Undo/Redo Copy/Paste Error feedback
Drag&Drop Outline Properties view
Contextual actions
March 25th, 2010© Sierra Wireless
And from an editing framework?
Standard widgets Extensible
Model-backed Simple

EMF Forms
A generic & tiny framework To build advanced editors on top of models Lives in PDE incubator• /cvsroot/eclipse• pde-incubator/modeling component
March 25th, 2010
EMF Forms: the Editor
EmfFormEditor<? extends EObject>• Generic editor• Configurable
• Custom Forms toolkit• Outline?• Rich error tooltips?• Source page?

EmfFormEditor
IEmfFormEditorConfig
EMF Forms: the Page
AbstractEmfFormPage• createContents()• bind()
March 25th, 2010© Sierra Wireless
EMF Forms: Master/Details blocks
EmfMasterDetailBlock /EmfDetailsPart• Ease the process of registering details pages• Hierarchical databinding
(DetailsObservable)

What? You’re not
using databinding
?!?
Databinding
Linking objects with each other in a declarative and simple way Allows to specify• Conversion rules• Validation policies
March 25th, 2010© Sierra Wireless
ViewModel
Controller
EMF Databinding
On top of the Edit layer Compact syntax Default behavior easily customizable
March 25th, 2010© Sierra Wireless
Databinding examples
bindingContext.bindValue(ViewerProperties.input().
observe(_propertiesMasterDetail.getTreeViewer())
,
getEditor().getInputObservable());
March 25th, 2010© Sierra Wireless
Databinding examples (MasterDetails)
bindingContext.bindValue(WidgetProperties.text(SWT.FocusOut).
observe(propertyComposite.getTextName())
, EMFEditProperties.value(getEditingDomain(),
ScrPackage.Literals.COMPONENT__NAME).
observeDetail(getCurrentSelection()));
March 25th, 2010© Sierra Wireless
EditingDomain?
Every operation on the model is a Command This command being stacked on a CommandStack
March 25th, 2010© Sierra Wireless
Undo/redo
CommandStack
Period.

Model validation
« Simple » validation rules• Directly in the model• Code mostly generated if you use the http://www.eclipse.org/emf/2002/Ecore#constraints annotation
• On-demand
March 25th, 2010© Sierra Wireless
Model validation
More complex rules• Contributed from the outside• Declaration• Fine-grained
March 25th, 2010© Sierra Wireless
EMF Validation
Constraints defined in extension points• Bound to specific feature(s) and operation(s)
They can be written in Java, OCL… or any language
March 25th, 2010© Sierra Wireless
Validation builder
ModelIncrementalBuilder• Generic builder• Detects modification on model files• Creates markers
• EMFFormEditor implements IGotoMarker
• Make things faster filtering on a content-type
