tkinter.simpledialog — Standard Tkinter input dialogs

源代码： Lib/tkinter/simpledialog.py

The tkinter.simpledialog module contains convenience classes and functions for creating simple modal dialogs to get a value from the user.

tkinter.simpledialog. askfloat ( title , prompt , ** kw )
tkinter.simpledialog. askinteger ( title , prompt , ** kw )
tkinter.simpledialog. askstring ( title , prompt , ** kw )

The above three functions provide dialogs that prompt the user to enter a value of the desired type.

class tkinter.simpledialog. Dialog ( parent , title = None )

The base class for custom dialogs.

body ( master )

Override to construct the dialog’s interface and return the widget that should have initial focus.

buttonbox ( )

Default behaviour adds OK and Cancel buttons. Override for custom button layouts.

tkinter.filedialog — File selection dialogs

源代码： Lib/tkinter/filedialog.py

The tkinter.filedialog module provides classes and factory functions for creating file/directory selection windows.

Native Load/Save Dialogs

The following classes and functions provide file dialog windows that combine a native look-and-feel with configuration options to customize behaviour. The following keyword arguments are applicable to the classes and functions listed below:

parent - the window to place the dialog on top of
title - the title of the window
initialdir - the directory that the dialog starts in
initialfile - the file selected upon opening of the dialog
filetypes - a sequence of (label, pattern) tuples, ‘*’ wildcard is allowed
defaultextension - default extension to append to file (save dialogs)
multiple - when true, selection of multiple items is allowed

Static factory functions

The below functions when called create a modal, native look-and-feel dialog, wait for the user’s selection, then return the selected value(s) or None to the caller.

tkinter.filedialog. askopenfile ( mode = 'r' , ** 选项 )
tkinter.filedialog. askopenfiles ( mode = 'r' , ** 选项 )

The above two functions create an Open dialog and return the opened file object(s) in read-only mode.

tkinter.filedialog. asksaveasfile ( mode = 'w' , ** 选项 )

创建 SaveAs dialog and return a file object opened in write-only mode.

tkinter.filedialog. askopenfilename ( ** 选项 )
tkinter.filedialog. askopenfilenames ( ** 选项 )

The above two functions create an Open dialog and return the selected filename(s) that correspond to existing file(s).

tkinter.filedialog. asksaveasfilename ( ** 选项 )

创建 SaveAs dialog and return the selected filename.

tkinter.filedialog. askdirectory ( ** 选项 )
Prompt user to select a directory.
Additional keyword option:
mustexist - determines if selection must be an existing directory.
class tkinter.filedialog. 打开 ( master = None , ** 选项 )
class tkinter.filedialog. SaveAs ( master = None , ** 选项 )

The above two classes provide native dialog windows for saving and loading files.

方便类

The below classes are used for creating file/directory windows from scratch. These do not emulate the native look-and-feel of the platform.

class tkinter.filedialog. 目录 ( master = None , ** 选项 )

Create a dialog prompting the user to select a directory.

注意

The FileDialog class should be subclassed for custom event handling and behaviour.

class tkinter.filedialog. FileDialog ( master , title = None )

Create a basic file selection dialog.

cancel_command ( event = None )

Trigger the termination of the dialog window.

dirs_double_event ( event )

Event handler for double-click event on directory.

dirs_select_event ( event )

Event handler for click event on directory.

files_double_event ( event )

Event handler for double-click event on file.

files_select_event ( event )

Event handler for single-click event on file.

filter_command ( event = None )

Filter the files by directory.

get_filter ( )

Retrieve the file filter currently in use.

get_selection ( )

Retrieve the currently selected item.

go ( dir_or_file = os.curdir , pattern = '*' , default = '' , key = None )

Render dialog and start event loop.

ok_event ( event )

Exit dialog returning current selection.

quit ( how = None )

Exit dialog returning filename, if any.

set_filter ( dir , pat )

Set the file filter.

set_selection ( file )

Update the current file selection to file .

class tkinter.filedialog. LoadFileDialog ( master , title = None )

A subclass of FileDialog that creates a dialog window for selecting an existing file.

ok_command ( )

Test that a file is provided and that the selection indicates an already existing file.

class tkinter.filedialog. SaveFileDialog ( master , title = None )

A subclass of FileDialog that creates a dialog window for selecting a destination file.

ok_command ( )

Test whether or not the selection points to a valid file that is not a directory. Confirmation is required if an already existing file is selected.

tkinter.commondialog — Dialog window templates

源代码： Lib/tkinter/commondialog.py
