Matic,
No problem. I'm glad you found the solution.

Hey Tony,
Thanks for the example. I tried it by adding a QGroupBox to the self.verticalLayout_2 \
and the gap was still there! So It was something with the QGroupBox, not the layout!
So I found this post: \

Long story short: It is a bug with the style on Linux. A workaround is to just offset \
the margin of the groupbox, like for example so:
groupbox.setStyleSheet("QGroupBox{padding-top:0px; margin-top:-25px}")
Thanks again Tony, for pointing me in the right direction!

I use QtDesigner to create my interface, but here is the code it
generates for the QDockWidget elements:
self.dockWidget = QtWidgets.QDockWidget(MainWindow)
self.dockWidget.setObjectName("dockWidget")
self.dockWidgetContents = QtWidgets.QWidget()
self.dockWidgetContents.setObjectName("dockWidgetContents")
self.verticalLayout_2 = QtWidgets.QVBoxLayout(self.dockWidgetContents)
self.verticalLayout_2.setObjectName("verticalLayout_2")
self.dataView = Temperature_DataView(self.dockWidgetContents)
self.dataView.setObjectName("dataView")
self.verticalLayout_2.addWidget(self.dataView)
spacerItem2 = QtWidgets.QSpacerItem(20, 40,
QtWidgets.QSizePolicy.Minimum, QtWidgets.QSizePolicy.Expanding)
self.verticalLayout_2.addItem(spacerItem2)
self.dockWidget.setWidget(self.dockWidgetContents)
So, this creates a content widget followed by a vbox layout widget with
the content widget as its parent. The widgets I want in the dock are
then added to the vbox layout and finally, the content widget is set as
the dock widget.
Hope this helps.
Regards,
Tony.
