Eclipse-plugin how to get current text editor corsor position

Question

I try to show popup dialog at text cursor position in editor. How can I get text cursor position of active editor (Point) and show popup dialog at this point?

Answer 1

You can use the getCursorPosition() method of AbstractTextEditor

Answer 2

Hi,

I have to do the same thing (get text cursor position of active Multipage editor) ... but don't manage to get it working.

I have a MultiPageEditor- and MultiPageEditorContributor class. Should I code the getCursorPosition method in one of these classes ? ... if so, how ? (please if possible some lines of code).

Thanks.

Answer 3

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.
