|
Native filechooser dialog facade.
|
|
=================================
|
|
|
|
open_file, save_file and choose_dir accept a number of arguments
|
|
listed below. They return either a list of paths (normally
|
|
absolute), or None if no file was selected or the operation was
|
|
canceled and no result is available.
|
|
|
|
Arguments:
|
|
* **path** *(string or None)*: a path that will be selected
|
|
by default, or None
|
|
* **multiple** *(bool)*: True if you want the dialog to
|
|
allow multiple file selection. (Note: Windows doesn't
|
|
support multiple directory selection)
|
|
* **filters** *(iterable)*: either a list of wildcard patterns
|
|
or of sequences that contain the name of the filter and any
|
|
number of wildcards that will be grouped under that name
|
|
(e.g. [["Music", "*mp3", "*ogg", "*aac"], "*jpg", "*py"])
|
|
* **preview** *(bool)*: True if you want the file chooser to
|
|
show a preview of the selected file, if supported by the
|
|
back-end.
|
|
* **title** *(string or None)*: The title of the file chooser
|
|
window, or None for the default title.
|
|
* **icon** *(string or None)*: Path to the icon of the file
|
|
chooser window (where supported), or None for the back-end's
|
|
default.
|
|
* **show_hidden** *(bool)*: Force showing hidden files (currently
|
|
supported only on Windows)
|
|
* **on_selection** *(func)*: Callback for fetching the selection.
|
|
|
|
Important: these methods will return only after user interaction.
|
|
Use threads or you will stop the mainloop if your app has one.
|
|
|
