[PyQt] Question about laying out widgets.

[Christian]

Hi Gabriele,
the incorrect line is:

       GeneralLayout.addWidget(self.summaryBox, 3, 0)

this line needs to be changed to:

       GeneralLayout.addWidget(self.summaryBoxScroll, 3, 0)

Because the summaryBox is a child of the Scroll Area, summaryBoxScroll 
and you should add only the top item.

But the result is very ugly, you have a scroll area, which contains the 
group box. Instead I would put the scroll area into the group box:

       self.summaryBox = QGroupBox("Project Management Layout")
       self.summaryBox.setMinimumHeight(100)

       self.summaryBoxTopLayout = QVBoxLayout()
       self.summaryBoxTopLayout.setContentsMargins(1, 1, 1, 1)
       self.summaryBox.setLayout(self.summaryBoxTopLayout)

       self.summaryBoxScroll = QScrollArea()
       self.summaryBoxScroll.setFrameStyle(QFrame.NoFrame)
       self.summaryBoxTopLayout.addWidget(self.summaryBoxScroll)

       self.summaryBoxTopWidget = QWidget()
       self.summaryBoxScroll.setWidget(self.summaryBoxTopWidget)

       self.summaryBoxLayout = QFormLayout(self.summaryBoxTopWidget)
       self.summaryBoxLayout.setSpacing(1)
       self.summaryBoxLayout.setSizeConstraint(QLayout.SetMinAndMaxSize)
       self.summaryBoxTopWidget.setLayout(self.summaryBoxLayout)

Further you should increase the initial frame size a bit.
