gtkTextIterBackwardVisibleLines {RGtk2} | R Documentation

## gtkTextIterBackwardVisibleLines

### Description

Moves `count` visible lines backward, if possible (if `count` would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then `FALSE` is returned. If `count` is 0, the function does nothing and returns `FALSE`. If `count` is negative, moves forward by 0 - `count` lines.

### Usage

### Arguments

``object`` | a `GtkTextIter`
``count`` | number of lines to move backward
