I've been trying to get a widget I made in qtCreator to work as an Rviz panel. I've had a lot of problems with inheritance. Specifically, in order for the definitions in my ui_mainwindow.h file to match the input argument defined in mainwindow, I need to inherit from QMainWindow, however, this and rviz::Panel both inherit from QObject, and so it is an ambiguous base.

The specific error which appears upon catkin_make, given the below code is as follows:

/home/rnd/catkin_ws/src/rviz_panel_test/src/mainwindow.cpp: In constructor ‘MainWindow::MainWindow(QWidget*)’:
/home/rnd/catkin_ws/src/rviz_panel_test/src/mainwindow.cpp:14:21: error: no matching function for call to ‘Ui::MainWindow::setupUi(MainWindow*)’
     ui->setupUi(this);
                     ^
In file included from /home/rnd/catkin_ws/src/rviz_panel_test/src/mainwindow.cpp:3:0:

     void setupUi(QMainWindow *MainWindow)
          ^
/home/rnd/catkin_ws/build/rviz_panel_test/ui_mainwindow.h:37:10: note:   no known conversion for argument 1 from ‘MainWindow*’ to ‘QMainWindow*’
