Gtk.EntryBuffer::delete_text

function vfunc_delete_text(position:Number, n_chars:Number):Number {
}

Deletes a sequence of characters from the buffer. n_chars characters are deleted starting at position. If n_chars is negative, then all characters until the end of the text are deleted.

If position or n_chars are out of bounds, then they are coerced to sane values.

Note that the positions are specified in characters, not bytes.
