is it possible to set IEMFListProperty as the input for GalleryViewer ?
is there sample for integrate EMF databinding with GalleryTreeViewer ?

Thanks.

GalleryTreeViewer treeViewer = ...

// input object that contains the root tree elements as children
EObject inputObject = ..

IEMFListProperty childrenProp =
EMFProperties.list(inputObjectChildrenStructuralFeature);

IEMFValueProperty[] columnProps = new IEMFValueProperty[] {
EMFProperties.value(property1),
EMFProperties.value(property2),
EMFProperties.value(property3),
}

ViewerSupport.bind(treeViewer, inputObject, childrenProp, columnProps);

Hope this helps,

Matthew

Hi, thanks for reply Smile
i have a model like :
Mail
- MailFolder (as root of group)
- MailEntry (as children)

here is my code :
GalleryTreeViewer viewer = new GalleryTreeViewer(parent);
EObject inputObject = mail;
IEMFListProperty childrenProp = EMFProperties.list(ModelPackage.Literals.PIM_MAIL__CURRENT_F OLDER);

IEMFValueProperty[] columnProps = new IEMFValueProperty[] {
EMFProperties.value(ModelPackage.Literals.MAIL_FOLDER__ENTRY ),
EMFProperties.value(ModelPackage.Literals.MAIL_ENTRY__CONTEN T)
};

ViewerSupport.bind(viewer, inputObject,childrenProp, columnProps);
return viewer;

that's code not work, that's only show the group of gallery Sad
can you tell me what is IEMFListProperty mean ?

Thanks,

Ok, you have a non-homogeneous tree structure. So you need to create a
list property that:
* For a Mail instance, observes the mail folders
* For a MailFolder instance, observes the mail entries

Use DelegatingListProperty:

IListProperty childrenProp = new DelegatingListProperty() {
IListProperty mailFolders = EMFProperties.list(
ModelPackage.Literals.PIM_MAIL__CURRENT_FOLDER);
IListProperty folderEntries = EMFProperties.list(
ModelPackage.Literals.PIM_MAIL_FOLDER__ENTRIES);

protected IListProperty doGetDelegate(Object source) {
if (source instanceof Mail)
return mailFolders;
if (source instanceof MailFolder)
return folderEntries;
}
};

> can you tell me what is IEMFListProperty mean ?

This is just a specialized IListProperty extension interface that lets
you do property chaining using EMF structural features:

IEMFListProperty foldersProp =
EMFProperties.list(ModelPackage.Literals.PIM_MAIL__CURRENT_F OLDER);
IEMFListProperty folderNamesProp =
foldersProp.values(ModelPackage.Literals.PIM_MAIL_FOLDER__NA ME);

Using this second property you could:

IEMFObservableList folderNamesObs = folderNamesProp.observe(mail);

...which gives you an observable list of folder *names*. Property
chaining allows you to project a value property over all elements of the
master list.

Hope this helps,

Matthew

Hi, Matthew
Thanks for reply and give me explanation about IEMFListProperty Smile and it's work now Smile

about Nebula Gallery :
when i move my application, it always refresh the viewer, how to make it not refresh the canvas when i move the application or minimize or maximize my application ?

about GalleryTreeViewer :
I have a model structure like a list, only 1 root and many list item, can it handle by GalleryTreeViewer ?
