QLabel + timers

[prophet0]

So im making a picture loop but seem to be a little stuck
in main

sClientz2_300_300Data = _myParse->getClientz2_300_300();
 
z2_300_300 = new QLabel(this);
    z2s1_Iterator = new QStringListIterator(sClientz2_300_300Data);
    z2_300_300->setGeometry(QRect(781,34,475,360));
    QTimer::singleShot(0,this, SLOT(startZ2S1()));

sClientz2_300_300Data = _myParse->getClientz2_300_300();

z2_300_300 = new QLabel(this);
    z2s1_Iterator = new QStringListIterator(sClientz2_300_300Data);
    z2_300_300->setGeometry(QRect(781,34,475,360));
    QTimer::singleShot(0,this, SLOT(startZ2S1()));

To copy to clipboard, switch view to plain text mode 

startZ2S1()

if(z2s1_Iterator->hasNext())
    {
        z2_300_300->clear();
        z2_300_300->setPixmap(QPixmap("/ttm/images/" + z2s1_Iterator->next()));
        z2_300_300->show();
    }
    if(!z2s1_Iterator->hasNext())
    {
        z2s1_Iterator->toFront();
    }
    emit doneZ2S1();

if(z2s1_Iterator->hasNext())
    {
        z2_300_300->clear();
        z2_300_300->setPixmap(QPixmap("/ttm/images/" + z2s1_Iterator->next()));
        z2_300_300->show();
    }
    if(!z2s1_Iterator->hasNext())
    {
        z2s1_Iterator->toFront();
    }
    emit doneZ2S1();

the problem i am having is getting this to display the first one only and dont display the next one untill this function is called again

how would i be able to modify my code to do the above?

Seems obvious enough... don't use a single shot timer if you want more than one shot. It is all in the QTimer details.

Thanks so much

so the fallowing code seems to be missing 1 of the strings in the list

From Debugger:

sClientz2_300_300Data	<2 items>	QStringList
			[0]	"fb70a926de17ed214dcbe1edd64c2d96.png"	QString
			[1]	"cd3eb7c9403913bf59b414dff8f64d54.png"	QString

sClientz2_300_300Data	<2 items>	QStringList
			[0]	"fb70a926de17ed214dcbe1edd64c2d96.png"	QString
			[1]	"cd3eb7c9403913bf59b414dff8f64d54.png"	QString

To copy to clipboard, switch view to plain text mode 

so the stringlist sClientz2_300_300Data has 2 items 0,1 but when the following is executed

in main()

z2_300_300 = new QLabel(this);
    timerZ2S1 = new QTimer(this);
    z2s1_Iterator = new QStringListIterator(sClientz2_300_300Data);
    z2_300_300->setGeometry(QRect(781,34,475,360));
    connect(timerZ2S1, SIGNAL(timeout()), this, SLOT(startZ2S1()));
    timerZ2S1->start(4000);

z2_300_300 = new QLabel(this);
    timerZ2S1 = new QTimer(this);
    z2s1_Iterator = new QStringListIterator(sClientz2_300_300Data);
    z2_300_300->setGeometry(QRect(781,34,475,360));
    connect(timerZ2S1, SIGNAL(timeout()), this, SLOT(startZ2S1()));
    timerZ2S1->start(4000);

To copy to clipboard, switch view to plain text mode 

in startZ2S1()

if(z2s1_Iterator->hasNext())
    {
        z2_300_300->clear();
        //QPixmap *pixmap = new QPixmap("/ttm/images/" + z2s1_Iterator->next());
        QString pixpath = "/ttm/images/" + z2s1_Iterator->next();
        z2_300_300->setPixmap(QPixmap(pixpath));
    }
    if(!z2s1_Iterator->hasNext())
    {
        z2s1_Iterator->toFront();
    }

if(z2s1_Iterator->hasNext())
    {
        z2_300_300->clear();
        //QPixmap *pixmap = new QPixmap("/ttm/images/" + z2s1_Iterator->next());
        QString pixpath = "/ttm/images/" + z2s1_Iterator->next();
        z2_300_300->setPixmap(QPixmap(pixpath));
    }
    if(!z2s1_Iterator->hasNext())
    {
        z2s1_Iterator->toFront();
    }

when the above code is executed it skips item 0 and goes to item 1 and loops it every time timeout() is called

where am i going wrong ?

It should work, unless you're doing something wrong somewhere else which you're not showing here.

Create a compilable example of the issue if you can.
I can bet you'll realize your mistake when preparing the example
