title: PyQt absolute position of QWidget
body: <p>I have a <code>QDialog</code> which has a layout, in this layout there are multiple <code>QWidgets</code>. Now I have a button, if the user presses this button I want to display a "tooltip" which displays some more information. This "tooltip" has to contain a layout.</p>
  
  <p>For this I wanted to use a <code>QWidget</code> with an absolute position. When I put together the code mentioned in <a href="https://stackoverflow.com/q/4329754/5934316">this question</a> the solution does not work for me. I have also tried to use the <code>QtWidget.raise_()</code> function but the <code>QWidget</code> is not being displayed.</p>
  
  <p>I stripped down my code to the following example:</p>
  
  <pre><code># creating content
  layout = QtWidgets.QVBoxLayout()
  for i in range(0, 10):
      layout.addWidget(QtWidgets.QLabel("line {} - bla bla bla bla bla bla".format(i)))
  
  widget = QtWidgets.QWidget()
  widget.setLayout(layout)    
  
  # creating dialog and apply the layout
  dialog = QtWidgets.QDialog()
  dialog.setLayout(layout)
  
  # creating the absolute positioned widget
  absolute_layout = QtWidgets.QVBoxLayout()
  absolute_layout.addWidget(QtWidgets.QLabel("Absolute positioned QWidget"))
  absolute_layout.addWidget(QtWidgets.QLabel("With some widgets in itself"))
  absolute_layout.addWidget(QtWidgets.QLabel("With some widgets in itself"))
  absolute_layout.addWidget(QtWidgets.QLabel("With some widgets in itself"))
  
  absolute = QtWidgets.QWidget(dialog)
  absolute.setLayout(absolute_layout)
  
  # show the absolute widget and move it
  absolute.show()
  absolute.move(10, 10)
  absolute.raise_()
  
  dialog.show()
  </code></pre>
  
  <p>The dialog is shown correctly with the content in the <code>layout</code> but the <code>absolute</code> is not being shown.</p>
  
  <p>What am I doing wrong?</p>
