Tkinter Dialogs
===============
:mod:`tkinter.simpledialog` --- Standard Tkinter input dialogs
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. module:: tkinter.simpledialog
:platform: Tk
:synopsis: Simple dialog windows
**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)
askstring(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.
.. method:: body(master)
Override to construct the dialog's interface and return the widget that
should have initial focus.
.. method:: buttonbox()
Default behaviour adds OK and Cancel buttons. Override for custom button
layouts.
:mod:`tkinter.filedialog` --- File selection dialogs
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. 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.
.. note:: The *FileDialog* class should be subclassed for custom event
handling and behaviour.
.. class:: FileDialog(master, title=None)
Create a basic file selection dialog.
.. method:: cancel_command(event=None)
Trigger the termination of the dialog window.
.. method:: dirs_double_event(event)
Event handler for double-click event on directory.
.. method:: dirs_select_event(event)
Event handler for click event on directory.
.. method:: files_double_event(event)
Event handler for double-click event on file.
.. method:: files_select_event(event)
Event handler for single-click event on file.
.. method:: filter_command(event=None)
Filter the files by directory.
.. method:: get_filter()
Retrieve the file filter currently in use.
.. method:: get_selection()
Retrieve the currently selected item.
.. method:: go(dir_or_file=os.curdir, pattern="*", default="", key=None)
Render dialog and start event loop.
.. method:: ok_event(event)
Exit dialog returning current selection.
.. method:: quit(how=None)
Exit dialog returning filename, if any.
.. method:: set_filter(dir, pat)
Set the file filter.
.. method:: set_selection(file)
Update the current file selection to *file*.
.. class:: LoadFileDialog(master, title=None)
A subclass of FileDialog that creates a dialog window for selecting an
existing file.
.. method:: ok_command()
Test that a file is provided and that the selection indicates an
already existing file.
.. class:: SaveFileDialog(master, title=None)
A subclass of FileDialog that creates a dialog window for selecting a
destination file.
.. method:: 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.
:mod:`tkinter.commondialog` --- Dialog window templates
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. module:: tkinter.commondialog
:platform: Tk
:synopsis: Tkinter base class for dialogs
**Source code:** :source:`Lib/tkinter/commondialog.py`
--------------
The :mod:`tkinter.commondialog` module provides the :class:`Dialog` class that
is the base class for dialogs defined in other supporting modules.
.. class:: Dialog(master=None, **options)
.. method:: show(color=None, **options)
Render the Dialog window.
