This snippet shows how to use tabs in Python.

Source code

import appuifw, e32
 
 
#Create an active object
app_lock = e32.Ao_lock()
#Define the exit function 
def quit():
	app_lock.signal()
appuifw.app.exit_key_handler = quit
 
#Define the tabs
tab1 = appuifw.Text(u"This is tab #1")
tab2 = appuifw.Text(u"This is tab #2")
tab3 = appuifw.Text(u"This is tab #3")
 
#Create a tab handler that switches between tabs
def handle_tab(index):
	#Switch to the tab according to index
	if(index==0):
		appuifw.app.body = tab1
	if(index==1):
		appuifw.app.body = tab2
	if(index==2):
		appuifw.app.body = tab3
 
##Set the tabs
appuifw.app.set_tabs([u"One", u"Two", u"Three"], handle_tab)
 
#Set the default tab to the first tab, for example
appuifw.app.body = tab1
 
#Wait for the user to request the exit
app_lock.wait()

Postconditions

Tabs are displayed as appuifw.Text() objects and the user can switch between them by using the left and right navigation keys.

Observations

When running a script that implements tabs in the Script Shell, after the script execution returns the tabs are still visible. To avoid this, add this in the exit function, above the line that signals the active object:

#Remove tabs and their handler function
appuifw.app.set_tabs([], None)
