Timer / Progress bar on a form to show countdown.

[Vish]

Hi All,
I'm trying to show a countdown timer on a form which displays the time
left for a discussion on some topic mentioned on that form.
I'm not able to decide or figure out the best way to do it, also I
couldn't find any earlier post discussing this.
If someone can help me suggesting this it will be really helpful and I
would be very thankful.
Regard
Vish.

Will the Timer in GWT help?

[Vishesh]

Thanks for replying.
But is there a way to show the timer on the rootpanel or other screen?
If there is I cant seem to find it anywhere.

Timer is just a class that helps you to do smth. periodically(see docs
for an example). You'll have to use it to update some label with your
time value.

Well using the Timer you can periodically request the server for the time remaining and update the count down Label. But this will require may be a server call in every min or few seconds. But I think the better approach is to get the remaining time at the first load and using a Timer to deduct a sec each time and update the label with new remaining time.

What timer function do you think will return the timer's current value
so that I can read and display on a lable?
I'm clueless :(

GWT-Ext has timer functions. Will that help you?
