How To Use
----------

The source code includes some examples which are in example directory, so you can take a qucik look before you
start coding, and thre are two part of this library as below

1. High Level API functions
---------------------------

Before start, you need to import api funcitons:

::
	from vsgui.api import *

Dialogs

::
	from vsgui.api import *

	# information dialog
	info(msg)

	# warring dialog
	warning(msg):

	# error dialog
	error(msg):

	# error dialog and terminate script
	die(msg):

	# notice dialog (does not work in Unity)
	notice(msg):

Input Text

::
	# input text
	ask_text(text, initial=None)

	# input password,
	ask_passwd(text)

	# check password
	#
	# - 1234 is the password we except user to type
	# - 5 means user can try to input 5 times if the password is wrong
	# - password is wrong is just a error message shows in an error dialog
	check_passwd('1234', 5, 'password is wrong')

Questions

::

	# ask user the anwser is yes or no
	ask_yesno(text, y=None, n=None):

	# ask user select a or b
	ask_ab(text, a, b):

	# ask user passowrd, and check it
	check_passwd(wanted, count=3, text='', errmsg='wrong password, try again!')

Progress
-------

::
	# launch a progress bar and create a update function
	update = progress('downloading files')

	# update progress bar message ot 'md5sum checking' and progessive number to 90
	update(90, 'md5sum checking')

	# launch a progress bar
	pulsate_progress('starting')

File
----

::

	# ask user to select a file path
	ask_filepath()

	# ask user to select multiple file paths
	ask_filepaths()

	# ask user to select a directory path
	ask_dirpath()

	# ask user to select multiple directory paths
	ask_dirpaths()

Other
-----

	ask_scalevalue('label')

2. Zenity Class
---------------

if api functions is not enough, you can use Zenity class direcly to get
more powerful feature.

::
	from vsgui.zenity import Zenity
	z = Zenity()

	# same as executing 'zenity --file-selection --filename=a.txt'
	z.file_selection(filename='a.txt')
