Hey Tony,<br>
<br>
Thanks for the example. I tried it by adding a QGroupBox to the self.<font size="2"><span style="font-size:11pt;">verticalLayout_2</span></font> and the gap was still there! So It was something with the QGroupBox, not the layout!<br>
<br>
So I found this post: <a href="https://stackoverflow.com/questions/43549990/removing-the-title-from-a-qgroupbox#43550049" id="LPNoLP376971">
https://stackoverflow.com/questions/43549990/removing-the-title-from-a-qgroupbox#43550049</a><br>
<br>
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:<br>
<blockquote style="margin-top: 0px; margin-bottom: 0px;"><br>
<span style="font-size: 11pt;">groupbox.setStyleSheet("QGroupBox{padding-top:0px; margin-top:-25px}")</span><br>
</blockquote>
<br>
Thanks again Tony, for pointing me in the right direction!<br>

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