Is your feature request related to a problem?

When creating a project, I encountered a problem with the entry object. I couldn't find a way to get the starting column and row of the selected text. I'd like to fix this, it doesn't look that hard.

Is it possible to construct a solution with the existing API?

Yes, i have a PR from forked repo

Describe the solution you'd like to see.

selectRow, selectColumn int -> SelectRow, SelectColumn int
