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', **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.

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 tkinter.filedialog.Directory(master=None, **options)¶

Create a dialog prompting the user to select a directory.

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)¶
