<div>I have a Qt GUI called MainWindow.<br>

<br>

I am rendering some 3D objects in the constructor of the MainWindow.<br>

Moreover I declared a custom class of the <span>vtkInteractorStyleTrackballCamera</span> in "MainWindow.cpp" like in this example:<br>

<a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents" target="_blank" class="x_OWAAutoLink" id="LPlnk920112">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents</a><br>

<br>

Now I would like to call a function from the MainWindow class in the function "OnLeftButtonDown<span class="x_br0">(</span><span class="x_br0">)</span>" from my custom class of the Interactor.<br>

<br>

I tried to inherit the MainWindow class to the custom Interactor class like this:<br>

<br>

<span>class customMouseInteractorStyle : public vtkInteractorStyleTrackballCamera</span>, MainWindow<br>

<br>

But this doesn't work.<br>

<br>

<span>How can I access the functions of the MainWindow there?<br>

Thank you</span></div>
