Supports the following Emacs-like key bindings: Ctrl-A Go to left edge of window. Ctrl-B Cursor left, wrapping to previous line if appropriate. Ctrl-D Delete character under cursor. Ctrl-E Go to right edge (stripspaces off) or end of line (stripspaces on). Ctrl-F Cursor right, wrapping to next line when appropriate. Ctrl-G Terminate, returning the window contents. Ctrl-H Delete character backward. Ctrl-J Terminate if the window is 1 line, otherwise insert newline. Ctrl-K If line is blank, delete it, otherwise clear to end of line. Ctrl-L Refresh screen. Ctrl-N Cursor down; move down one line. Ctrl-O Insert a blank line at cursor location. Ctrl-P Cursor up; move up one line. Move operations do nothing if the cursor is at an edge where the movement is not possible. The following synonyms are supported where possible: KEY_LEFT = Ctrl-B, KEY_RIGHT = Ctrl-F, KEY_UP = Ctrl-P, KEY_DOWN = Ctrl-N KEY_BACKSPACE = Ctrl-h c C s? | | _ | | _ | j � d | _ d | _ | j d � d S( Ni ( R t insert_modet _update_max_yxt stripspacest Nonet lastcmdt keypad( t selfR R ( ( s& /usr/lib64/python2.7/curses/textpad.pyt __init__+ s c C s3 | j j � \ } } | d | _ | d | _ d S( Ni ( R t getmaxyxt maxyt maxx( R R R ( ( s& /usr/lib64/python2.7/curses/textpad.pyR 3 s c C s� | j � | j } xk t r� t j j | j j | | � � t j j k rc t | j | d � } Pn | d k rs Pn | d } q W| S( su Go to the location of the first blank on the given line, returning the index of the last non-blank character.i i ( R R t TrueR t asciiR t incht SPt min( R t yt last( ( s& /usr/lib64/python2.7/curses/textpad.pyt _end_of_line8 s - c C s | j � | j j � \ } } d } x� | | j k sF | | j k r� | j ra | j j � } n y | j j | � Wn t j k r� n X| j s� t j j | � r� Pn | } | j j � \ } } | d k r( | | f } q( q( W| d k r| j j | � n d S( N( R R t getyxR R R R R R R t errorR t isprintt move( R t chR! t xt backyxt oldch( ( s& /usr/lib64/python2.7/curses/textpad.pyt _insert_printable_charF s$ ! c C so | j � | j j � \ } } | | _ t j j | � rk | | j k sX | | j k rk| j | � qkn | t j j k r� | j j | d � n�| t j j t j t j j t j f k rj| d k r� | j j | | d � nY | d k r� nJ | j r"| j j | d | j | d � � n | j j | d | j � | t j j t j f k rk| j j � qkn| t j j k r�| j j � n�| t j j k r�| j r�| j j | | j | � � qk| j j | | j � n�| t j j t j f k rO| | j k r#| j j | | d � qk| | j k r5qk| j j | d d � n | t j j k red S| t j j k r�| j d k r�d S| | j k rk| j j | d d � qkn�| t j j k r | d k r�| j | � d k r�| j j � qk| j j | | � | j j � nO| t j j k r>| j j � n-| t j j t j f k r�| | j k rk| j j | d | � | | j | d � k r�| j j | d | j | d � � q�qkn� | t j j k r�| j j! � n� | t j j" t j# f k rk| d k rk| j j | d | � | | j | d � k rh| j j | d | j | d � � qhqkn d S( s!
