QSignalMapper用法

      当多个signal连接到一个同一个slot，而且slot对每个signal处理不同时，用到QSignalMapper

 

void MainWindow::SetSignalSlot()
{
    connect(m_pBtn1, SIGNAL(clicked()), m_pSignalMapper, SLOT(map()));
   
    m_pSignalMapper->setMapping(m_pBtn1, QEasingCurve::OutSine);

    connect(m_pBtn2, SIGNAL(clicked()), m_pSignalMapper, SLOT(map()));
  
    m_pSignalMapper->setMapping(m_pBtn2, QEasingCurve::OutSine);
    connect(m_pSignalMapper, SIGNAL(mapped(int)),this, SLOT(SetAnimation(int)));
}
