Hello,  
I have a Python program where I want to get the active browser node of a qMRMLSequenceBrowserToolBar. However this variable is inaccessible from Python. Any ideas on how to get this variable?

Good catch. This method was not marked for Python wrapping. I’ve [added it now](https://github.com/Slicer/Slicer/commit/fab4ec043672efc3434ae29fea498979b9ae7b17), so the method will be available in Python from tomorrow in the Slicer Preview Release.

Until then, you can get the active browser node by connecting to function to the `activeBrowserNodeChanged(vtkMRMLNode* activeBrowserNode)` signal.
