Re: [mitk-users] Rendering viewer update

Hi Hortense,

did you manage to update the render window?

Maybe a image->Modified() call is necessary after changing the image contents and before calling this->RequestRenderWindowUpdate()?

Best,
Sascha

Hi Sascha, all,

Thank you for your indication.
I have been adding the following line to my code

either

this->RequestRenderWindowUpdate(mitk);

or

this->RequestRenderWindowUpdate(mitk::RenderingManager::REQUEST_UPDATE_ALL);

but the behavior does not change, viewers are not updated.
Would you have any idea why?

Best,

Hortense

Once I reset my image, I still see in the viewer the old image; only when I scroll through the image the image displayed will be updated.

Is there a way to ‘force’ the refresh of the viewer display?

if you want to trigger the update from within a sub-class of QmitkAbstractView, use

http://docs.mitk.org/2013.12/classQmitkAbstractView.html#adb0d756b51c3734bd3031618fe5aaea7

otherwise have a look at the mitk::RenderingManager class.

Best,
Sascha
