Hi python experts,

I have used the following piece of code:

import appuifw,e32

app_lock = e32.Ao_lock()

def quit():
    app_lock.signal()
appuifw.exit_key_handler = quit

f = open(u"c:\\loc_details.txt","rb")
p = f.readlines()

for x in p:
    x = x.replace('\r\n','')
    y = x.split(',')        
    fields = [(u'Location','text',u''+y[0]),
              (u'Latitude','text',u''+y[1]),
              (u'Longitude','text',u''+y[2])]
    flags = appuifw.FFormViewModeOnly
        
    f = appuifw.Form(fields,flags)
    f.execute()
    e32.ao_sleep(1)

app_lock.wait()

And my loc_details.txt have some text like this:

House,12.924198,77.621949
Office,12.8381576,77.6571918

My query is: I have to display the location details dynamically... But my code displays the next location detail from the text file only after me clicking "Back" key.. I want it to display each location detail automatically say after 2 secs...

How to get this done......
Thanks in advance for ur quick responses

Sorry, but your code is not meant to do this.

I cannot see a timer of 2 seconds which calls a function implemented anywhere in the code. Nor can I see a loop?

hello divya

what you should do is open the file, read its content and display the contents on the screen using a canvas or anything else.

Now for making it dynamic you can use the timers which will implement above algorithm for every particular interval.

For timers you can search the wiki.

Thanks gaba........ I tried using timer.. But still not working properly... Can someone fix this and help me resolve it...

It is very urgent.........

import appuifw,e32

timer = e32.Ao_timer()
delay = 1
app_lock = e32.Ao_lock()

def quit():
    app_lock.signal()
appuifw.exit_key_handler = quit

f = open(u"c:\\loc_details.txt","rb")
p = f.readlines()

def do_this():
    fields = [(u'Location','text',u''+y[0]),
              (u'Latitude','text',u''+y[1]),
              (u'Longitude','text',u''+y[2])]
    flags = appuifw.FFormViewModeOnly
        
    f = appuifw.Form(fields,flags)
    f.execute()
    
for x in p:
    x = x.replace('\r\n','')
    y = x.split(',')
    timer.after(delay,do_this)

app_lock.wait()

Where is it I have gone wrong..

HI v divya

I have a code for this in my home but only tonight I can send it to you (I am work).
I used a listbox instead. For avoiding flickering, before doing a new set_list() I saved the last selected item so set_list(items,last_selected) will make this flickering less noticeable.
