Hi Stefan,
My class extending mitk::PropertyListReplacedObserver is in a module
now, but I still can't get it to work. GetPeristenceService() always
return a nullptr, wathever I try. I tried mimicking OpenCVVideoSupport
as much as possible, to no avail. Do you have any ideas on what I could
have done wrong? Thank you for your time.

Hi Nil,
I would recommend to move such code into a module. That’s why it is
working in Modules/IGTUI/Qmitk and Modules/OpenCVVideoSupport/UI. The
alternative is to make your plugin context available by providing a
static access method for the context in your plugin activator. See
org_mitk_gui_qt_simulation_Activator.h for an example. In
QmitkSimulationView.cpp right below the includes I wrote a helper
method to get a service by using this plugin context. You should be
able to get the persistence service like this without the macros (just
follow the macros, they are doing nothing special, they are just for
convenience). I still would recommend the former solution though, as
it is clean and wouldn’t require any workaround code.
I’ll correct the typo in GetPeristenceService() for the upcoming release.
Best,
Stefan

Hi Stefan,
I tried the persistence service and I got this error each time I use
GetPeristenceService().
WARNING: In us::GetModuleContext at
\Modules\CppMicroServices\core\include\usGetModuleContext.h:57 :
Module 'org_imeka_qt_brainanalysis' unknown. The calling module
probably misses a US_MODULE_NAME compile definition and/or a call to
US_INITIALIZE_MODULE in one of its source files.
I didn't find such a thing in the QmitkOpenCVVideoControls example so
I randomly added a US_INITIALIZE_MODULE in my plugin activator and now
GetPersistenceService() finds its module but returns a nullptr. I
can't give you more information than that because PersistenceService.h
is a macro hell.
Do you know how to make it work?

Hi Stefan,
/These properties can be stored inside a MITK scene together with
the data so that the user loads data and restores the application
state at once./ - MITK Persistence Service
I can't test it now but this is exactly what I needed. Thank you.

Betreff: [mitk-users] Scene properties
Hi all,
Is there a concept of scene property? I have some parameters(widget) in
my plugin, like MinFiberLength, MaxFiberLength, etc. which are not saved
when I save the scene. These parameters don't belong to any node, and
they don't fit as a Preference because the user will probably change
them when loading other data. That leaves me with "scene property", but
I don't think they exist.
My plan is to put the properties in a hidden node, but it does seem like
an hack. It's still the less hackish method I can find without modifying
MITK's code. Is there a right way to do that?
