源码: Lib/tkinter/filedialog.py


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

原生 加载/保存 对话框.

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”, \*options*)

tkinter.filedialog.askopenfiles(mode=”r”, \*options*)

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

tkinter.filedialog.asksaveasfile(mode=”w”, \*options*)

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

tkinter.filedialog.askopenfilename(\*options*)

Additional keyword option:

class tkinter.filedialog.Open(master=None, \*options*)

class tkinter.filedialog.SaveAs(master=None, \*options*)

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