Will QPushButton::setChecked(true); change my Icon?

[rawfool]

I'm working on button properties similar to Start/Pause & Stop.
The scenario is like this:
1. Two Buttons: Start/Pause & Stop which is related to a process
2. On click of play, pause icon is shown and Stop button is enabled.
3. On click of pause, start icon is shown, and stop button is enabled.
4. I get one signal from other process - start: pause icon is shown & stop button should be enabled.

My button properties are like this

m_pbScan = new QPushButton(this);
m_pbScan->setIcon(QIcon(":/imgs/scanStart.png"));
m_pbScan->setCheckable(true);
connect(m_pbScan, SIGNAL(clicked(bool)), this, SLOT(onScanBtnClicked(bool)));
 
// SLOT:
void CStatusPage::onScanBtnClicked(bool click)
{
    qDebug() << click;
    if(click)
    {
        emit scanBtnClicked();
        m_pbScan->setIcon(QIcon(":/imgs/scanPause.png"));
    }
    else
    {
        m_pbScan->setIcon(QIcon(":/imgs/scanStart.png"));
        emit pauseBtnClicked();
    }
    m_pbScanStop->setEnabled(true);
}

m_pbScan = new QPushButton(this);
m_pbScan->setIcon(QIcon(":/imgs/scanStart.png"));
m_pbScan->setCheckable(true);
connect(m_pbScan, SIGNAL(clicked(bool)), this, SLOT(onScanBtnClicked(bool)));

// SLOT:
void CStatusPage::onScanBtnClicked(bool click)
{
    qDebug() << click;
    if(click)
    {
        emit scanBtnClicked();
        m_pbScan->setIcon(QIcon(":/imgs/scanPause.png"));
    }
    else
    {
        m_pbScan->setIcon(QIcon(":/imgs/scanStart.png"));
        emit pauseBtnClicked();
    }
    m_pbScanStop->setEnabled(true);
}

To copy to clipboard, switch view to plain text mode 

When I get a signal from some other event promptin for start, then I'm calling this function -

void CStatusPage::scanOn()
{
    m_pbScan->setChecked(true);
}

void CStatusPage::scanOn()
{
    m_pbScan->setChecked(true);
}

To copy to clipboard, switch view to plain text mode 

My doubt is, will the setChecked(true); automatically invoke connect and set icon to pauseIcon?
I trying to implement a logic that works with above mentioned scenarios.
Thank you.
