Tkinter ダイアログ
******************


"tkinter.simpledialog" --- Standard Tkinter input dialogs
=========================================================

**ソースコード:** 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)

   上の３つの関数は、ユーザーに期待する型の値を入力を促すダイアログを
   提供します。

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

   カスタムダイアログ用の基底クラスです。

   body(master)

      ダイアログインターフェースの構築をオーバーライドし、初期フォーカ
      スを持つべきウィジットを返します。

   buttonbox()

      デフォルト動作はOKとCancelボタンを追加します。カスタムのボタンレ
      イアウトが必要であればオーバーライドします。


"tkinter.filedialog" --- File selection dialogs
===============================================

**ソースコード:** Lib/tkinter/filedialog.py

======================================================================

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


ネイティブの読み込み/保存ダイアログ
-----------------------------------

下記のクラスは、振る舞いをカスタマイズできる設定オプション付きの、ネイ
ティブルック＆フィールと統合したファイルダイアログを提供します。以下の
キーワード引数は、下記で列挙するクラスや関数に適用できます。

      *parent* - ダイアログをその上に表示するウィンドウ

      *title* - ウィンドウのタイトル

      *initialdir* - 最初に表示するディレクトリ

      *initialfile* - ダイアログを表示した際に選択するファイル

      *filetypes* - (ラベル, パターン) のタプルからなるシーケンスで、'*' ワイルドカードが利用できます

      *defaultextension* - ファイルに追加するデフォルトの拡張子 (保存ダイアログ向け)

      *multiple* - 真の場合、複数要素の選択を許可します

**静的なファクトリ関数**

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)
tkinter.filedialog.askopenfilenames(**options)

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

tkinter.filedialog.asksaveasfilename(**options)

   Create a "SaveAs" dialog and return the selected filename.

tkinter.filedialog.askdirectory(**options)

      Prompt user to select a directory.
      Additional keyword option:
         *mustexist* - determines if selection must be an existing directory.

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.

**便利なクラス**

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.Directory(master=None, **options)

   Create a dialog prompting the user to select a directory.

注釈:

  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
==================================================

**Source code:** Lib/tkinter/commondialog.py

======================================================================

The "tkinter.commondialog" module provides the "Dialog" class that is
the base class for dialogs defined in other supporting modules.

class tkinter.commondialog.Dialog(master=None, **options)
