Get the Widget containing the renderd Image from Mayas Render View

[Simon.weck]

Hello everyone, 

I am trying to make an experimental tool that modifies the existing Maya Render View and swaps out the current rendered Image. I want to get the widget that contains the rendered image and change it. 

I got the Render View Dialog through MQtUtil with this code: 

 
I looked through all children of the Render View and tracked the widget that seems to contain the rendered image down to a QWidget. The problem ist that this widget has no children and there is no QImage or a similar widget that actualy displays the rendering. 

 

I also removed all of the widgets in the dialog that wont remove the rendered image to make sure I dont miss anything. 

 

These are the widgets that are left in the dialog:

 

I also have a tool that prints the hirarchy of the widgets when hovering over it. When I hover over the renderd image I get this hirarchy. The widget at the top that has no Object name set is the widget that seems to contain the rendered image

 

Am I missing something or how can I get the widget that displays the rendered image?
