I have a TreeViewer that navigates an object hierarchy that is not file
based. I have context popup menus for the various objects (which are
different in type as we go down the hierarchy), and for each object type I
want to open an editor (probably FormToolkit derived). But I have NO CLUE
how to open an editor that is based on an Iselection object rather than on a
file type. Any suggestions would be greatly appreciated.

Hi,

You will need to implement org.eclipse.ui.IEditorInput for the objects in
your tree. I usually set my viewer to listen to double clicks and then call:

PlatformUI.getWorkbench().getActiveWorkbenchWindow()
.getActivePage().openEditor(new myEditrInput(), "editor.id", true);

Regards,

Tim.

I used this code for the listener:

treeViewer.addDoubleClickListener(new IDoubleClickListener() {
public void doubleClick(DoubleClickEvent e) {
IStructuredSelection selection = (IStructuredSelection)
treeViewer.getSelection();
getEditor(selection.getFirstElement());
}
});

And this code for opending the editor:

public void getEditor(Object obj){
String editorID = null;
IEditorPart editor = null;
IEditorInput input = null;
if (obj instanceof Agency){
input = new AgencyEditorInput((Agency) obj);
editorID = AgencyEditor.ID;
}
if (obj instanceof AMITables){
//input = new AgencyEditorInput((Agency) obj);
//editorID = AgencyEditor.ID;
}
if (obj instanceof Grant){
input = new GrantEditorInput((Grant) obj);
editorID = GrantEditor.ID;
}
if (obj instanceof Employee){
input = new StaffEditorInput((Employee) obj);
editorID = StaffEditor.ID;
}
if (obj instanceof County){

}
if (obj instanceof User){
input = new UserEditorInput((User) obj);
editorID = UserEditor.ID;
}
editor =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().findEditor(input);
if (editor != null){

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().activate(editor);
return;
}
try{

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().openEditor(input,
editorID);
}catch(Exception e){
System.out.println(e);
}
}
