For my QGIS Plugin, that I started with the QGIS Plugin Builder, I built a
QDockWidget and populated it with some functions.
Now I want to add a
QMainWindow, since I need more space for further options, but would like to keep my
QDockWidget, in case that one only needs the "simple" Version of the plugin.
I now have build a simple
QMainWindow with Qt and want to add it to my plugin. And this is the point where I don't know how to continue.
