title: Qt Set background Color of QPushButton
body: <p>I am very new to Qt and I am making some changes to a program. What I am trying to do is get a QPushButton called <code>start_</code> to change its color when clicked. The button is declared here:</p>
  
  <pre><code>void StatusTab::CreateControlFrame() {
  start_ = new QPushButton(tr("Start Capture"), this);
  start_-&gt;setSizePolicy(QSizePolicy::Minimum, QSizePolicy::Minimum);
  button_layout-&gt;addWidget(start_, 0, 0, 1, 1);
  connect(start_, SIGNAL(clicked()), this, SLOT(OnStartClicked()));
  }
  </code></pre>
  
  <p>I am guessing that the code needs to be added in the <code>OnStartClicked()</code> method but I am not sure what functions I need to use. Any help would be appreciated.</p>
