<div class="gmail_extra" style><br></div><div class="gmail_extra" style>I found out about this by having a button that connected to a function that only did self.widget.Initialize().</div><div class="gmail_extra" style>So Initializing the widget wont work if the QtGui havent started yet (sorta makes sense).</div>
<div class="gmail_extra" style><br></div><div class="gmail_extra" style>The tutorials on this although have to be updated to reflect this.</div><div class="gmail_extra" style><br></div><div class="gmail_extra" style>Hope this helps some other poor souls in the same situation.</div>
