[salmanmanekia]

Hi ALL,
I am developing an application in which i want the clock to show continous time as of my PC(machine) time,when i run the application it shows the time but the time issnt refreshing ,it isnt changing at all ,i have QTimer for that purpose but it doesnt seem to work !!..
anyhelp would be apprecited..

HEADER FILE

QTime time;
QTimer *update;
QFont fontTime;
QGraphicsTextItem *timeItem;
QString timeString;
..
public slots:
void updateTime();

QTime time;
QTimer *update;
QFont fontTime;
QGraphicsTextItem *timeItem;
QString timeString;
..
public slots:
void updateTime();

To copy to clipboard, switch view to plain text mode 

SOURCE FILE

time  = QTime::currentTime();
update = new QTimer();
connect(update,SIGNAL(timeout()),this,SLOT(updateTime()));
update->start(1000);
timeString = time.toString("hh:mm A");
..  .. 
timeItem = scene->addText(timeString);
timeItem->setFont(fontTime);
timeItem->setTextWidth(100);
timeItem->setPos(TIME_TEXT_X,TIME_TEXT_Y);
..  ..
void TrainingUI::updateTime()
{
	time = QTime::currentTime();
}

time  = QTime::currentTime();
update = new QTimer();
connect(update,SIGNAL(timeout()),this,SLOT(updateTime()));
update->start(1000);
timeString = time.toString("hh:mm A");
..  .. 
timeItem = scene->addText(timeString);
timeItem->setFont(fontTime);
timeItem->setTextWidth(100);
timeItem->setPos(TIME_TEXT_X,TIME_TEXT_Y);
..  ..
void TrainingUI::updateTime()
{
	time = QTime::currentTime();
}

You need to call timeItem->setText(....) in TrainingUI::updateTime().

thanks for the reply...but there doesnt seem to be any function as setText()...

Sorry, that should be QGraphicsTextItem::setPlainText() or QGraphicsTextItem::setHtml().

I think you need to add the following code inside the slot.

timeString = time.toString("hh:mm A");
...
...
timeItem = scene->addText(timeString);
timeItem->setFont(fontTime);
timeItem->setTextWidth(100);
timeItem->setPos(TIME_TEXT_X,TIME_TEXT_Y);

timeString = time.toString("hh:mm A");
...
...
timeItem = scene->addText(timeString);
timeItem->setFont(fontTime);
timeItem->setTextWidth(100);
timeItem->setPos(TIME_TEXT_X,TIME_TEXT_Y);

Looks like the code is outside.

[EDIT] Rather, you will need to update the text of your timeItem inside the slot.

Thanks,it worked..i was calling slot for just updating and not showing it on the view...bad mistake from me..
