\modulesynopsis{Interface to the S60 global UI notifiers.}

The \module{globalui} module offers an interface to the S60 global UI notifiers. 
This allows a global note and query to be launched from an application which does not 
have a UI environment. 
The \module{globalui} module have functions:

\begin{funcdesc}{global_note}{note_text\optional{, type}}
Displays a note of the chosen type with \var{note_text} 
(Unicode). The default value for \var{type} is \code{'info'}. \var{type} can be 
one of the following strings: \code{'error'}, \code{'text'}\footnote{Applicable for 
platforms 2.6 and later.}, \code{'warn'}, \code{'charging'}, \code{'wait'}, 
\code{'perm'},\code{'not_charging'}, \code{'battery_full'}, \code{'battery_low'}, 
\code{'recharge_battery'}, or \code{'confirm'}. 
\end{funcdesc}

\begin{funcdesc}{global_query}{query_text\optional{, timeout}}
Displays a global confirmation query with \var{query_text} (Unicode). Returns 
\code{1} when the user presses 'Yes' and \code{0} otherwise. If the user does 
not respond to the query within \var{timeout} seconds, returns \code{None}. 
If the \var{timeout} value is 0, then the query waits indefinitely for user input. 
The default value for \var{timeout} is 0. The \var{timeout} value should be an integer.
\end{funcdesc}

\begin{funcdesc}{global_msg_query}{query_text, header_text\optional{, timeout}}
Displays a global message query with \var{query_text}(Unicode). \var{header_text} is used 
to set the heading string of the query. Returns \code{1} when the user 
presses 'OK' and \code{0} otherwise. If the user does not respond to the query within 
\var{timeout} seconds, returns \code{None}. If the \var{timeout} value is \code{0}, then the query 
waits indefinitely for user input. The default value for \var{timeout} is \code{0}. 
The \var{timeout} value should be an integer.
\end{funcdesc}

\begin{funcdesc}{global_popup_menu}{option_items\optional{, header_text, timeout}} 
Displays a global menu with \var{option_items}(Unicode). \var{header_text}\footnote{This \
field will be ignored for platform 2.0.} is used to set the heading string of the 
menu. \var{header_text} is applicable for platforms 2.6 and later. If no value is 
passed for \var{header_text}, then the header will not be displayed. Returns the index value 
of the selected item from the list. If the user does not respond to the menu within 
\var{timeout} seconds, returns \code{None}. If the \var{timeout} value is \code{0}, 
then the menu waits indefinitely for the input. The default value for \var{timeout} 
is \code{0}. The \var{timeout} value should be an integer.
\end{funcdesc}

Example:
\begin{verbatim}
>>> import globalui, time
...
>>> text_to_show = u"text for showing note"
>>> globalui.global_note(text_to_show,'error')
>>> time.sleep(6)
>>> globalui.global_note(text_to_show)
>>> time.sleep(6)
>>> result = globalui.global_query(u"do you want to continue ?")
>>> time.sleep(6)
>>> listresult = globalui.global_popup_menu([u"MenuItem1", u"MenuItem2"],u"Select item",5)
...   
\end{verbatim}
