Dynamically adding context/popup menus to Editors [message #329223]

Hi All,

I wish to dynamically add a context/popup menu to an editor created by
me. I have declared a TextEditor inisde my editor. I have been following
"Building Commercial-Quality plugins" but I am unable to find any
examples of adding these menus dynamically *for TextEditors*. All the
examples have viewers or trees. Can someone please enlighten me about
how to add these menus. Any code samples would be greatly useful. I have
looked at the editorContextMenuAboutToShow() in TextEditor but it is a
protected method and I am already extending EditorPart.

I have been struggling for days with this problem.

Prasad

Declared a text editor "inside" your editor? What do you mean? Are you
in a MultiPageEditorPart?

Normally for text based editors, you would subclass AbstractTextEditor
or TextEditor itself. Another alternative is to use a TextViewer or
SourceViewer in your EditorPart (both of which are configurable).

Or do you mean you are using TextEditor inside your editor with
something like "textEditor.createPartControl(parent)"?

If the latter, that really won't work reliably since you can't host an
editor in an editor (at least not well).

As for context menus, you can add to them programmatically if you are
the EditorPart that creates them or if owning EditorPart exposes the
context MenuManager some way. The other alternative is to use
org.eclipse.ui.popupMenus/viewerContribution,
org.eclipse.ui.popupMenus/objectContribution or
org.eclipse.ui.menus/menuContribution ... once you find the correctly
registered context menu id.

Hi Paul,

Thanks for your response.

Yes I am using a MultiPageEditorPart. My editor class(say GrammerEditor)
extends MultipageEditorPart. I declared a private instance of TextEditor
in this editor class(GrammerEditor). I have been trying to add the menu
to this private instance (texteditor) rather than the GrammerEditor.

Well truth is I was sticking to the examples in the book. So I guess I
would now extend TextEditor rather than MultipageEditorPart inspite of
loosing multi-tab functionality which I was hoping to use later. If I
extend TextEditor I hope to use the editorContextMenuAboutToShow() to
create the menus.

This is another problem. I am still confused about the targetID for
popupMenus/viewerContribution. Is this achieved by appending ".context"
to the id of the editor?

No, for example use ALT+SHIFT+F1 while in the java editor. It will list
a set of active context menu IDs. They default to the viewId when
registerContextMenu(*) is called with no ID, or to the ID specified in
the registerContextMenu(*) call.
