Member Function Documentation

void Controller::timerEvent

(

QTimerEvent *

event

)

[protected, virtual]

This event handler can be reimplemented in a subclass to receive timer events for the object.

QTimer provides a higher-level interface to the timer functionality, and also more general information about timers. The timer event is passed in the event parameter.

See also:

startTimer(), killTimer(), event()

Reimplemented from QObject.

{
    Q_UNUSED(event);
    if (car->isValid())
        ui.label->setText("connected");
    else
        ui.label->setText("disconnected");
