Syntax Coloring for a Non-File based Editor [message #336137]

Hi everybody,

I am trying to get the syntax coloring working when setting an editor's
content programmatically (for an existing editor, e.g. the Java one),
but I have not come to a solution until now. I am not able to set the
content type programmatically. The syntax coloring appears to work only
when opening a file which extension is defined in the
org.eclipse.ui.editors extension point.

What I am doing until now:

- define MyEditorInput extending IEditorInput

- define MyDocumentProvider extending AbstractDocumentProvider and
override createDocument, where I return a Document with the content I
want if getting a parameter of type MyEditorInput. (I tried to override
the method getContentType(Object), but it is never called.)

- Open the Java editor programmatically with my custom input.

Anyone has an idea what I should do for the syntax coloring to work or
how I can set the content type programmatically?

Thanks in advance.
Cheers,

Patrick

Anyone?

It seems to me like a tricky thing, since syntax coloring within an
editor is linked to a file extension. I am wondering if no one had a
similar problem...

This is not true. Syntax coloring has nothing to do with a file or a
file extension.

Have you tried implementing IStorageEditorInput and *not* overriding
the document provider?
