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 FcCs.||_||_|d|_d|_|ddSNr)r insert_mode_update_max_yx stripspaceslastcmdZkeypad)selfrr rrr __init__+s zTextbox.__init__cCs&|j\}}|d|_|d|_dSr )rZgetmaxyxmaxymaxx)rrrrrr r3s zTextbox._update_max_yxcCsX||j}tj|j||tjjkr@t|j|d}qTn |dkrJqT|d}q|S)zuGo to the location of the first blank on the given line, returning the index of the last non-blank character.rr)rrrasciirinchZSPmin)ryZlastrrr _end_of_line8s zTextbox._end_of_linecCs||j\}}d}||jks.||jkr|jr>|j}z|j|Wntj k rdYnX|jrtj |szq|}|j\}}|dkr||f}q|dk r|jj |dS)N) rrgetyxrrr rrrerrorrisprintmove)rchrxZbackyxZoldchrrr _insert_printable_charFs$  zTextbox._insert_printable_charcCsV||j\}}||_tj|rJ||jks<||jkrF| |n|tjj krh|j |dn|tjj tj tjjtjfkr|dkr|j ||dnB|dkrn8|jr|j |d||dn|j |d|j|tjjtjfkrR|jnL|tjjkr"|jn0|tjjkrb|jrN|j |||n|j ||jn|tjjtjfkr||jkr|j ||dn ||jkrn|j |ddn|tjjkrdS|tjjkr |jdkrdS||jkrR|j |ddnF|tjjkrZ|dkr@||dkr@|jn|j |||jn|tjjkrt|jn|tjjtjfkr||jkrR|j |d||||dkrR|j |d||dnz|tjj kr|j!n`|tjj"tj#fkrR|dkrR|j |d||||dkrR|j |d||ddS)z!Process a single editing command.rr)$rrrrrrrrrr ZSOHrZSTXZKEY_LEFTZBSZ KEY_BACKSPACErrZdelchZEOTZENQZACKZ KEY_RIGHTZBELNLZVTZdeletelnZclrtoeolZFFrefreshZSOZKEY_DOWNZSIZinsertlnZDLEZKEY_UP)rrrrrrr do_command_sr            zTextbox.do_commandc Csd}|t|jdD]}|j|d||}|dkrF|jrFqt|jdD]4}|jrj||krjq|tt j |j ||}qT|jdkr|d}q|S)z.Collect and return the contents of the window.rr ) rrangerrrrrrchrrrr)rresultrstoprrrr gathers    zTextbox.gatherNcCs<|j}|r||}|sq||s(q4|jq|S)z2Edit in the widget window and collect the results.)rZgetchr#r"r*)rZvalidaterrrr edits   z Textbox.edit)F)N) __name__ __module__ __qualname____doc__rrrr r#r*r+rrrr r s Ar __main__cCsfd\}}d\}}||d|dt||||}t||d|d|||||t|S)N) )zUse Ctrl-G to end editing.r)ZaddstrrZnewwinr r"r r+)ZstdscrZncolsZnlinesrrrrrr test_editboxs r6zContents of text box:) r/rZ curses.asciir r r,r6wrapperstrprintreprrrrr s ,
