interesting problem : slider control..position passing to QListIterator object?

I wish to connect the slider with the iterator position(i.e. if the slider is pressed/released, the the image should be displayed accordingly)............ I can make a connect(localSlider,SIGNAL(sliderReleased()),..... ....) .....in the SLOt function I'll call localSlider->value() and accept the integeral value of the index of sldier value..............but how would I set the localIterator's position accordingly????
Below is a very simple to understand code snippet...


//CODE:

void VideoDisplayer::passFileNameToVideoLabel(QStringLi st fileName,QStringListIterator *iterator,QSlider *slider)
{
timer = new QTimer;
temp = fileName;
localIterator = iterator;
localSlider = slider;
}


void VideoDisplayer::playVideo()
{
connect(timer, SIGNAL(timeout()),this, SLOT(nextPicture()));
timer->start(1000);
}


void VideoDisplayer::nextPicture()
{
if(localIterator->hasNext())
{
videoLabel->setPixmap(QPixmap(localIterator->next()));
videoLabel->adjustSize();
videoLabel->setScaledContents(true);
//localSlider->setValue();
localSlider->setValue(temp.indexOf(localIterator->peekPrevious()));
//label->show();
}
else
{
disconnect(timer, SIGNAL(timeout()),this, SLOT(nextPicture()));

timer->stop();
localIterator->toFront();
localSlider->setValue(0);

}
}

Dispense with the iterator and keep the list and a simple index number (member variables) then:

Code:

---

void VideoDisplayer::nextPicture() { 
  if (m_index < list.size()-1) 
    m_index++; 
  showPicture(); 
}
 
void VideoDisplayer::prevPicture() { 
  if (m_index > 0) 
    m_index--; 
  showPicture(); 
}
 
void sliderReleased() {
  int newIndex = localSlider->value();
  if (...)   // bounds checks omitted
    m_index = newIndex;
  showPicture();
}
 
void showPicture() {
  // bounds checks omitted
  videoLabel->setPixmap(QPixmap(list.at(m_index)));
  videoLabel->adjustSize();
  videoLabel->setScaledContents(true);
  localSlider->setValue(m_index);
}

---

or some variation on the theme.

Edit: Use [code] tags around your code, it is the # on the editor tool bar.

Thanx but I don't want to dispense with the "iterator" as it is being used and passed by many functions and classes already.............I am sure there must be a way to do it with the "iterator".................................ple ase if you could tell me how to do it with the "iterator"!!

OK. Your choice. Since the Java style list iterator interface has no method to set the current item by index you have no choice but to toFirst() and then next() "n+1" times. The STL-style iterator could do this a little more easily with the "i += n" notation.

thanx a lot ...........
