FileBrowser
|
|
===========
|
|
The :class:`FileBrowser` widget is an advanced file browser. You use it
|
|
similarly to FileChooser usage.
|
|
It provides a shortcut bar with links to special and system directories.
|
|
When touching next to a shortcut in the links bar, it'll expand and show
|
|
all the directories within that directory. It also facilitates specifying
|
|
custom paths to be added to the shortcuts list.
|
|
It provides a icon and list view to choose files from. And it also accepts
|
|
filter and filename inputs.
|
|
To create a FileBrowser which prints the currently selected file as well as
|
|
the current text in the filename field when 'Select' is pressed, with
|
|
a shortcut to the Documents directory added to the favorites bar::
|
|
import os
|
|
from kivy.app import App
|
|
class TestApp(App):
|
|
def build(self):
|
|
user_path = os.path.join(get_home_directory(), 'Documents')
|
|
browser = FileBrowser(select_string='Select',
|
|
favorites=[(user_path, 'Documents')])
|
|
browser.bind(on_success=self._fbrowser_success,
|
|
on_submit=self._fbrowser_submit)
|
|
return browser
|
|
def _fbrowser_success(self, instance):
|
|
print(instance.selection)
|
|
def _fbrowser_submit(self, instance):
|
|
print(instance.selection)
|
|
TestApp().run()
|
|
:Events:
|
|
`on_success`:
|
|
Fired when the `Select` buttons `on_release` event is called.
|
|
`on_submit`:
|
|
Fired when a file has been selected with a double-tap.
