title: Qt - Detect item information change in QListView
body: <p>I have a QListView which is connected to a QStandardItemModel. How do I detect any information change in the model or the QListView? I tried the Signals and Slots with the itemChanged() for the model but it seems to crash the whole program.</p>
  
  <pre><code>Qbject::connect(bugModel, SIGNAL(itemChanged(QStandardItem*)), this, SLOT(bugInfoChanged()));
  </code></pre>
  
  <p>That is the code I'm using to connect the Signal. the function bugInfoChanged() just runs a qDebug() that says "Changed". But when I start the program, it shows a crash error.</p>
