forward_visible_lines


Description:

public bool forward_visible_lines (int count)

Moves count visible lines forward, 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 backward by 0 - count lines.

Parameters:

this

a TextIter

count

number of lines to move forward

Returns:

whether this moved and is dereferenceable
