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 cCsm||_||_|jƒ\|_|_|jd|_|jd|_d|_d|_|jdƒdS(Ni( R t insert_modetgetmaxyxtmaxytmaxxt stripspacestNonetlastcmdtkeypad(tselfR R((s$/usr/lib/python2.7/curses/textpad.pyt__init__+s    cCs{|j}xktrvtjj|jj||ƒƒtjjkrYt|j|dƒ}Pn|dkriPn|d}q W|S(suGo to the location of the first blank on the given line, returning the index of the last non-blank character.ii(RtTrueRtasciiR tinchtSPtmin(Rtytlast((s$/usr/lib/python2.7/curses/textpad.pyt _end_of_line5s  - cCsÖ|jjƒ\}}||jks3||jkrÒ|jrN|jjƒ}ny|jj|ƒWntjk rxnX|jrÒ|jjƒ\}}tj j |ƒrÏ|j |ƒ|jj ||ƒqÏqÒndS(N( R tgetyxRRRRRRterrorRtisprintt_insert_printable_chartmove(RtchR txtoldchtbackytbackx((s$/usr/lib/python2.7/curses/textpad.pyR&Bs   cCse|jjƒ\}}||_tjj|ƒra||jksN||jkra|j|ƒqan|tjj kr‰|jj |dƒnØ|tjj tj tjj tjfkr`|dkrÙ|jj ||dƒnY|dkrènJ|jr|jj |d|j|dƒƒn|jj |d|jƒ|tjj tjfkra|jjƒqan|tjjkr‚|jjƒnß|tjjkrÕ|jr¼|jj ||j|ƒƒqa|jj ||jƒnŒ|tjjtjfkrE||jkr|jj ||dƒqa||jkr+qa|jj |ddƒn|tjjkr[dS|tjjkr¬|jdkr€dS||jkra|jj |ddƒqanµ|tjjkr|dkrï|j|ƒdkrï|jjƒqa|jj ||ƒ|jjƒnO|tjjkr4|jjƒn-|tjjtjfkr»||jkra|jj |d|ƒ||j|dƒkr¸|jj |d|j|dƒƒq¸qan¦|tjjkrÝ|jj ƒn„|tjj!tj"fkra|dkra|jj |d|ƒ||j|dƒkr^|jj |d|j|dƒƒq^qandS(s!Process a single editing command.ii(#R R#RRRR%RRR&tSOHR'tSTXtKEY_LEFTtBSt KEY_BACKSPACERR"tdelchtEOTtENQtACKt KEY_RIGHTtBELtNLtVTtdeletelntclrtoeoltFFtrefreshtSOtKEY_DOWNtSItinsertlntDLEtKEY_UP(RR(R R)((s$/usr/lib/python2.7/curses/textpad.pyt do_commandTsp *   ' !- -c Csãd}xÖt|jdƒD]Á}|jj|dƒ|j|ƒ}|dkr]|jr]qnx_t|jdƒD]J}|jr||krPn|ttj j |jj ||ƒƒƒ}qqW|jdkr|d}qqW|S(s.Collect and return the contents of the window.tiis ( trangeRR R'R"RRtchrRRR(RtresultR tstopR)((s$/usr/lib/python2.7/curses/textpad.pytgather”s/cCs`xS|jjƒ}|r'||ƒ}n|s3qn|j|ƒsFPn|jjƒq|jƒS(s2Edit in the widget window and collect the results.(R tgetchRDR=RJ(RtvalidateR(((s$/usr/lib/python2.7/curses/textpad.pytedit¤sN( t__name__t __module__t__doc__tFalseRR"R&RDRJRRM(((s$/usr/lib/python2.7/curses/textpad.pyRs  @ t__main__cCs‡d\}}d \}}|j|d|dƒtj||||ƒ}t||d|d||||ƒ|jƒt|ƒjƒS( Ni iiiisUse Ctrl-G to end editing.i(i i(ii(taddstrRtnewwinRR=RRM(tstdscrtncolstnlinesR R R ((s$/usr/lib/python2.7/curses/textpad.pyt test_editbox²s  & sContents of text box:(( RPRt curses.asciiRRRNRXtwrappertstrtrepr(((s$/usr/lib/python2.7/curses/textpad.pyts   ž
