Hello,
I need to have the usual text editor, but it should basically edit a
relatively small String (which is part of a model object), and NOT be
associated to a file.
The editor will be on a page of a MultiPageEditor, and I need to be able
to instantiate it myself.
What is a good way of doing this/where can I find good documentation?
I've played with the TextEditor in jface, but I had all kind of problems
instantiating it and putting it in a MultiPageEditor page.
Thanks

It is quite straight forward to use the MultiPageEditor. The MultiPageEditor
example offers a starting point and the MultiPageEditor API also tells you
what to do.
Essentially you need to implement (override) the createPages() method, in
which you add all the pages to the editor using
addPage(IEditorPart, IEditorInput)
For your particular problem this means you create an IEditorPart (or extend
one of the abstract editor classes) and add it to your MPE using that
method.
e.g.
protected void addPages() {
javaEditor = new JavaEditor();
IEditorInput javaInput = new JavaEditorInput(javaCode);
int index = addPage(javaEditor, javaInput);
setPageText(index, "Java: "+javaCode.getClassName());
}
this would create a new JavaEditor and add it to the MPE with the given
JavaEditorInput (your input as described bye anonymous)
the title of the editors tab in the MPE is then set to "Java: " followed by
the classname. Here you can put anything you want...
