I have a QMainWindow application A which opens another QMainWindow application B. The second application (B) has a widget that displays a QwtPlot with a QwtPlotZoomer.
I can run application B independently or open it as a window through application A.

When I run B independently, it works well: I can zoom in and out of the plot.
When I run A and create B as a child, I get two signals - 1. the original zoom 2. moving of the window inside the central widget.

I'm not interested in moving the window when I'm in the QwtPlot widget (only zooming).
How can I disable the second signal for only that widget? (As I still want to be able to move the window when outside the plot widget)
I didn't connect the move signal so I assume it's done by default?
