how to close our own application ??

[adhavanj]

hi all i want to close my application automatically, when the system time reaches the user given time.
any ideas???
Thank you all in advance

Create a QTimer object that emits a timeout() signal every few seconds.
Connect the signal to a slot that checks if the required time has elapsed and, if it has, call this->close()

Why not just compute the time to the given time and set that for the timer interval?

As it is a user supplied time it may change after the timer is set.
Checking periodically saves having to cancel and restart the timer if the user changes the value.

If the user time changes you simply reset the timer. You probably need to be able to cancel it anyway, if some user activity interrupts things.

Polling is evil on a phone (or on any device, actually).

Clearly Nokia don't think it is that bad or they wouldn't have provided the QTimer class with a polling function!
But yes, on second thoughts it is probably better to set the timer for the time the application needs to close......

Any tool can be abused.

Please note, that Qt is cross-platform framework, which is available on dozen architectures and only some of them are mobile platforms.
