Classes: - FileDialog - LoadFileDialog - SaveFileDialog This module also presents tk common file dialogues, it provides interfaces to the native file dialogues available in Tk 4.2 and newer, and the directory dialogue available in Tk 8.3 and newer. These interfaces were written by Fredrik Lundh, May 1997. é)Ú*)ÚDialog)Ú commondialogNc@s eZdZdZdZd$dd„Zejdddfdd „Zd%d d „Z d d „Z dd„Z dd„Z dd„Z dd„Zdd„Zd&dd„Zdd„Zdd„Zd'dd„Zd d!„Zd"d#„ZdS)(Ú FileDialogaëStandard file selection dialog -- no checks on selected file. Usage: d = FileDialog(master) fname = d.go(dir_or_file, pattern, default, key) if fname is None: ...canceled... else: ...open file... All arguments to go() are optional. The 'key' argument specifies a key in the global dictionary 'dialogstates', which keeps track of the values for the directory and pattern arguments, overriding the values passed in (it does not keep track of the default argument!). If no key is specified, the dialog keeps no memory of previous state. Note that memory is kept even when the dialog is canceled. (All this emulates the behavior of the Macintosh file selection dialogs.) zFile Selection DialogNcCs°|dkr|j}||_d|_t|ƒ|_|j |¡|j |¡t|jƒ|_|jjt t dt |jƒ|_ |j jt t d|j   d|j¡t |jƒ|_|jjtt d|j  d|j¡t|jƒ|_|jjttdt|jƒ|_|jjttdt|jd|jdfd|_|jjtttd|j ¡}|j |dd…|dd…¡|j  d |j¡|j  d |j¡|jj|jd fd t|jƒ|_|jjt tdt|jd|jdfd|_!|j!jt ttd|jj|j!d fd |j! ¡}|j! |dd…|dd…¡|j!  d |j"¡|j!  d |j#¡t$|jd |j%d|_&|j&jt dt$|jd|jd|_'|j'jt tdt$|jd|j(d|_)|j)jtd|j *d|j(¡|j  d|j(¡|j  d|j(¡dS)N)ÚsideÚfillz)ÚexpandrrÚset)ZexportselectionZyscrollcommand)rrrézzZyview)ÚcommandZOK)Útextr )rZFilter)rrÚCancelZWM_DELETE_WINDOWzz)+ÚtitleÚmasterÚ directoryZToplevelÚtopZiconnameZFrameZbotframeZpackZBOTTOMÚXZEntryÚ selectionZbindÚok_eventÚfilterZTOPÚfilter_commandZmidframeZYESZBOTHZ ScrollbarZfilesbarZRIGHTÚYZListboxÚfilesZbindtagsÚfiles_select_eventÚfiles_double_eventZconfigZdirsbarZLEFTÚdirsÚdirs_select_eventÚdirs_double_eventZButtonÚ ok_commandZ ok_buttonZ filter_buttonÚcancel_commandZ cancel_buttonZprotocol)ÚselfrrZbtags©r!ú7/opt/alt/python37/lib64/python3.7/tkinter/filedialog.pyÚ__init__3sh                zFileDialog.__init__rÚcCsÜ|r|tkrt|\|_}n2tj |¡}tj |¡r<||_ntj |¡\|_}| |j|¡| |¡|  ¡|j   ¡|j   ¡|j  ¡d|_|j ¡|rÌ| ¡\}}|jrÀtj |j¡}||ft|<|j  ¡|jS)N)Ú dialogstatesrÚosÚpathÚ expanduserÚisdirÚsplitÚ set_filterÚ set_selectionrrZ focus_setrZwait_visibilityZgrab_setÚhowrZmainloopÚ get_filterÚdirnameZdestroy)r Z dir_or_fileÚpatternÚdefaultÚkeyrr!r!r"Úgors*           z FileDialog.gocCs||_|j ¡dS)N)r-rÚquit)r r-r!r!r"r4‹szFileDialog.quitcCs | ¡dS)N)r)r Úeventr!r!r"rszFileDialog.dirs_double_eventcCs@| ¡\}}|j d¡}tj tj |j|¡¡}| ||¡dS)NÚactive) r.rÚgetr&r'ÚnormpathÚjoinrr+)r r5ÚdirÚpatZsubdirr!r!r"r’s  zFileDialog.dirs_select_eventcCs | ¡dS)N)r)r r5r!r!r"r˜szFileDialog.files_double_eventcCs|j d¡}| |¡dS)Nr6)rr7r,)r r5Úfiler!r!r"r›s zFileDialog.files_select_eventcCs | ¡dS)N)r)r r5r!r!r"rŸszFileDialog.ok_eventcCs| | ¡¡dS)N)r4Ú get_selection)r r!r!r"r¢szFileDialog.ok_commandc Cs0| ¡\}}yt |¡}Wntk r8|j ¡dSX||_| ||¡| ¡tj g}g}xH|D]@}tj   ||¡}tj   |¡r|  |¡qft ||¡rf|  |¡qfW|j dt¡x|D]}|j t|¡q¾W|j dt¡x|D]}|j t|¡qèWtj  | ¡¡\} } | tjkr"d} | | ¡dS)Nrr$)r.r&ÚlistdirÚOSErrorrÚbellrr+ÚsortÚpardirr'r9r)ÚappendÚfnmatchrÚdeleteÚENDÚinsertrr*r=Úcurdirr,) r r5r:r;ÚnamesZsubdirsZ matchingfilesÚnameÚfullnameÚheadÚtailr!r!r"r¥s6          zFileDialog.filter_commandcCsN|j ¡}tj |¡}|dd…tjks4tj |¡rBtj |d¡}tj |¡S)Néÿÿÿÿr) rr7r&r'r(Úsepr)r9r*)r rr!r!r"r.Ás   zFileDialog.get_filtercCs|j ¡}tj |¡}|S)N)rr7r&r'r()r r<r!r!r"r=Ès  zFileDialog.get_selectioncCs | ¡dS)N)r4)r r5r!r!r"rÍszFileDialog.cancel_commandcCs„tj |¡sPy t ¡}Wntk r0d}YnX|rPtj ||¡}tj |¡}|j dt ¡|j  t tj |pttj |pzd¡¡dS)Nrr) r&r'ÚisabsÚgetcwdr?r9r8rrErFrGrH)r r:r;Úpwdr!r!r"r+Ðs    zFileDialog.set_filtercCs,|j dt¡|j ttj |j|¡¡dS)Nr)rrErFrGr&r'r9r)r r<r!r!r"r,ÜszFileDialog.set_selection)N)N)N)N)Ú__name__Ú __module__Ú __qualname__Ú__doc__rr#r&rHr3r4rrrrrrrr.r=rr+r,r!r!r!r"rs" ?
