The `QmitkStdMultiWidget` contains three functions to change the widget plane mode:
These functions are never used anywhere. Instead, changing the widget plane mode is done by receiving signals from the `QmitkRenderWindow`s (signal `ChangeCrosshairRotationMode`). The used ìnt` argument is transformed into a specific interaction scheme and used to change the interaction mode of the mouse mode switcher (which loads a new .xml interaction-config file).
Additionally the mentioned functions wouldn't work since they use a specific `enum` for the `int` argument. This is problematic, since the the enums do not contain the //ROTATIONLINKED// mode and therefore would set the wrong interaction scheme.
Furthermore I cannot find any call to
Additionally the emitted signal `WidgetPlanesRotationLinked` is never used anywhere.
It seems that all interaction scheme changes are done by the render window menus and the other mentioned functions are not needed anymore. However, interaction scheme describes different levels of modes. This will be further explained and put up for discussion in
