Hello Amir,
Thank you! it was useful to me your explanation about the global rendering
manager.
Regarding the function you suggested me
<https://phabricator.mitk.org/source/mitk/browse/master/Modules/RenderWindowManager/src/mitkRenderWindowViewDirectionController.cpp;48733f55943c98170b2339eb85503edc4d5052d8$83-110>
, it is private and I couldn't access it. To solve the issue I found that
you can provide a specific RenderingManager to the QmitkStdMultiWidget
constructor, so I created a different Rendering Managers for each one, then
I just called:
my_rendering_manager->InitializeViewsByBoundingObjects(my_data_storage);
Now it is working perfectly!
Thank you again.
Best regards,
Rocío
