Scrolling problems

[salvador]

Hey,
i am trying to implement a slider with these requirements: (1) when i have i single step call a specific function (2) when the slider makes more steps (slidermoved) wait some time and the call the same function. Untill now i have done these:
This is the connection of the signals,

  connect(ui->verticalScrollBar, SIGNAL(sliderMoved(int)), this, SLOT(sliderMoved_slot()));
  connect(ui->verticalScrollBar, SIGNAL(valueChanged(int)), this, SLOT(sliderSingleStep_slot()));
  connect (&m_Timer, SIGNAL(timeout()), this, SLOT (requestSlot()));

and the implementation of the slots,

void VGrid::sliderSingleStep_slot()
{
    requestSlot();
}

void VGrid::sliderMoved_slot()
{
    disconnect(ui->verticalScrollBar, SIGNAL(valueChanged(int)), this, SLOT(sliderSingleStep_slot()));
    drawGrid();
    m_Timer.start(500);
    connect(ui->verticalScrollBar, SIGNAL(valueChanged(int)), this, SLOT(sliderSingleStep_slot()));
}

I used the disconnect() because i don't want the valueChanged() signalto be emmited when the sliders moves. I want it to be emmited only when i have a single step. I have tried also the blockSignals() function. None of these two worked.
What am i doing wrong? Any other suggetion for the implementation of the slider are very welcomed.

Hi,

In that case have a look at "actionTriggered":http://qt-project.org/doc/qt-4.8/qabstractslider.html#actionTriggered

seems that the "solution with actionTriggered":http://qt-project.org/forums/viewthread/28225/ wasn't successful?!
