QSystemAlignedTimer Class Reference

Member Function Documentation

QSystemAlignedTimer::QSystemAlignedTimer ( QObject * parent = 0 )

Constructs a QSystemAlignedTimer object with the given parent.

QSystemAlignedTimer::~QSystemAlignedTimer ()

Destructs the QSystemAlignedTimer

void QSystemAlignedTimer::error ( QSystemAlignedTimer::AlignedTimerError error ) [signal]

This signal is emitted when an error happens.

AlignedTimerError QSystemAlignedTimer::lastError () const

Returns the last AlignedTimerError.

void QSystemAlignedTimer::singleShot ( int minimumTime, int maximumTime, QObject * receiver, const char * member ) [static]

This static function starts a timer to call a slot after a minimumTime interval has elapsed, and ensures that it will be called before the maximumTime has elapsed.

These values are specified in seconds.

The receiver is the receiver object and the member is the slot.

See also setSingleShot().

void QSystemAlignedTimer::start ( int minimumTime, int maximumTime ) [slot]

Starts the timer with the minimal interval of minimumTime, and maximum interval maximumTime in seconds.

This is not a guaranteed interval, and the timeout signal may be fired at any time, depending on other clients attached to this timer.

In the case of minimalInterval of 0, it means 'wake me up when someone else is woken up'.

If you need a window of time in which your timer should fire, use QSystemAlignedTimer::setWindow

void QSystemAlignedTimer::start () [slot]

Starts the alignedtimer.

void QSystemAlignedTimer::stop () [slot]

Stops this timer request.

void QSystemAlignedTimer::timeout () [signal]

This signal is emitted when the timer times out.

void QSystemAlignedTimer::wokeUp ()

This should be called when the application wakes up via other means than QSystemAlignedTimer timeout.

Other applications that are in their wakeup window *may* be woken up. Single-shot timer is canceled, and reoccuring timer interval will restart.

Symbian does not support this wokeUp call for reoccuring timers and will simply ignore it.
