|
**Source code:** :source:`Lib/tkinter/simpledialog.py`
|
|
|
|
--------------
|
|
|
|
The :mod:`tkinter.simpledialog` module contains convenience classes and
|
|
functions for creating simple modal dialogs to get a value from the user.
|
|
|
|
|
|
.. function:: askfloat(title, prompt, **kw)
|
|
askinteger(title, prompt, **kw)
|

The above three functions provide dialogs that prompt the user to enter a value
|
|
of the desired type.
|
|
|
|
.. class:: Dialog(parent, title=None)
|
|
|
|
The base class for custom dialogs.

|
|
should have initial focus.
|
|
|
|
.. method:: buttonbox()
|
|
|

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. module:: tkinter.filedialog
|
|
:platform: Tk
|
|
:synopsis: Dialog classes for file selection
|
|
|
|
**Source code:** :source:`Lib/tkinter/filedialog.py`
|
|
|
|
--------------
|
|
|
|
The :mod:`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.
|
|
|
|
.. function:: askopenfile(mode="r", **options)
|
|
askopenfiles(mode="r", **options)
|
|
|
|
The above two functions create an :class:`Open` dialog and return the opened
|
|
file object(s) in read-only mode.
|
|
|
|
.. function:: asksaveasfile(mode="w", **options)
|
|
|
|
Create a :class:`SaveAs` dialog and return a file object opened in write-only mode.
|
|
|
|
.. function:: askopenfilename(**options)
|
|
askopenfilenames(**options)
|
|
|
|
The above two functions create an :class:`Open` dialog and return the
|
|
selected filename(s) that correspond to existing file(s).
|
|
|
|
.. function:: asksaveasfilename(**options)
|
|
|
|
Create a :class:`SaveAs` dialog and return the selected filename.
|
|
|
|
.. function:: askdirectory(**options)
|
|
|
|
| Prompt user to select a directory.
|
|
| Additional keyword option:
|
|
| *mustexist* - determines if selection must be an existing directory.
|
|
|
|
.. class:: Open(master=None, **options)
|
|
SaveAs(master=None, **options)
|
|
|
|
The above two classes provide native dialog windows for saving and loading
|
|
files.
|
|
|
|
**Convenience classes**
|
|
|
|
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:: Directory(master=None, **options)
|
|
|
|
Create a dialog prompting the user to select a directory.
|
|
|

|
|
handling and behaviour.

|
|
|
.. class:: FileDialog(master, title=None)
