Hello everyone,

I'm working with 3D data in my application, which I display using the 
ImageView class. My app closely resembles this GeeksForGeeks 
<https://www.geeksforgeeks.org/pyqtgraph-setting-image-to-image-view/> example, 
but I have a custom ROI button that displays a custom ROI box in the 
display.

*My question:* is there a way I can define the ROI Box to exist on only 
specified frames? For example, I want the ROI box to exist from frames 3 to 
10 and 20 to 25.

Thanks in advance!

Rishav
