Find the current caret position in a TextEditor [message #242501]

I'm writing an extension plug-in to any text editor.
The plug-in gets events when the text is selected and it is easy to
replace the selected text with the required text.
However, I want to have the ability to insert text into the current
caret position.
How can I find the current caret position in the text editor?

From the start event I have the ITextEditor and I can get the IDocument
as well. But I have no access to the getCaretPosition method. Since
there is no selection highlighted, the selection object is empty.

Thanks
Yigal

I don't know how to do it if all you have is an ITextEditor, but in the
editor I'm working on, which extends
org.eclipse.ui.editors.text.TextEditor, I can do it using the
ISourceViewer, then a possible code inside my editor could be:

Position position = this.getSourceViewer().getSelectedRange();

And to replace something, I can do something like:

idocument.replace(point.x, 0, "</" + str + ">");

Regards and I hope it helps!!

I need to give you more information. I've created a plugin that extended
the org.eclipse.ui.popupMenu. It adds a new menu item on any popup
menu in any text editor.
The main action class in the plugin receives a notification with the
current editor. The getSourceViewer is protected and not accesseable.
My code need to insert text at current caret position. How can I find
the current position from a TextEditor when all methods are protected?
