          I'm not exactly sure what do you mean under "show popup dialog at this point", but do something like this:



          IEditorPart editor =  PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor();
          if (editor instanceof ITextEditor) {
          ISelectionProvider selectionProvider = ((ITextEditor)editor).getSelectionProvider();
          ISelection selection = selectionProvider.getSelection();
          if (selection instanceof ITextSelection) {
          ITextSelection textSelection = (ITextSelection)selection;
          int offset = textSelection.getOffset(); // etc.
          }
          }


          Of course, in production code do null checks etc.

          • I need (X,Y) point (in pixels) to show a popup dialog and I want to show it under the text cursor like the code completion popup. In your code you get text offset in symbols, how to convert this offset to point in pixels. Or may be exists another way to show popup under the text cursor?

          You can use the getCursorPosition() method of AbstractTextEditor

            Not only is it protected, it also returns a string "description of the cursor position", which is not what the OP was asking for at all.
