Rendering an ITextEditor inside a SWT Composite [message #1828291]

Hi,

Is it possible to render an ITextEditor inside a SWT Composite? if so, how can we achieve that or something similar? (*)

Context:
We have a plugin using the Generic Text Editor (ExtensionBasedTextEditor) with a custom Language Server using LSP4E.
We want to open a "configuration dialog" (WizardPage) and have the editor (just the "viewport") with full capabilities (suggestions, syntax highlight, error markers, etc) to allow inline editions of a text without having a file.

Thank you very much in advance!

(*): We were trying multiple (hacky) ways but without much luck.

Quick update for future reference.

"Editors are displayed only in the editor area, so no, you can't get a StructuredTextEditor in a wizard page." (reference)

The way to go to do it is to use a SourceViewer (and configure a lot of things) and give a parent Composite to it. See: http://wiki.eclipse.org/Platform_Text

Xtext has an embedded editor (not an IEditorPart) that also could be taken as a reference. See the EmbeddedEditor class and the ones related in that package.

To understand a little bit more about this Xtext embedded editor see these (a bit old) slides: https://www.slideshare.net/meysholdt/lightweight-xtext-editorsasswtwidgets
