\page Step09Page MITK Tutorial - Step 9: A plug-in

MITK uses a very modular concept to maximize reusability and portability. A MITK application based on the BlueBerry
application framework (for example the MITK Workbench) consists of several bundles (or plug-ins). A bundle can contain
resources and program logic. It can also contribute so-called Views to the main application, which provide a specific
user interface for controlling the bundles functions.

\verbatim
documentation\doxygen\
  modules.dox......................... Doxygen file for documenting your plug-in

resources\
  icon.png............................ The icon of your plug-in. GIMP or other programs (including your text editor)
                                       can be used to change this

src\internal\
  QmitkRegionGrowingView.cpp.......... The most important file, implementing behaviour
  QmitkRegionGrowingView.h............ Header file of the functionality
  QmitkRegionGrowingViewControls.ui... XML file of the Qt Designer, describes buttons, combo boxes, etc. of your controls

CMakeLists.txt \...................... Build system related files for CMake
files.cmake    /
manifest_headers.cmake................ Information about your plug-in
plugin.xml ........................... BlueBerry integration
\endverbatim

If you are not familiar with Qt development, please look into
<a href="https://doc.qt.io/qt-6/qtdesigner-manual.html">this Qt company page describing .ui files</a>

The C++ files implement a subclass of QmitkAbstractView. In this special case of QmitkRegionGrowing, we added the option to set some seed points and run a region grower. If you are interested in the concrete changes necessary to turn a freshly generated QmitkRegionGrowing into an integrated one:

The plug-in will be build as part of MITK Workbench. Do use it start MITK Workbench an select the region growing view in the view menu.

To add a mitk::PointSet for the seed points:
QmitkRegionGrowingView.h

Add includes and forward declarations:
\snippet QmitkRegionGrowingView.h includes

Add the point set and a pointer to a QmitkPointListWidget as a private member:
\snippet QmitkRegionGrowingView.h members

QmitkRegionGrowingView.cpp

CreateQtPartControl():
\snippet QmitkRegionGrowingView.cpp cpp-createqtpartcontrol

To use the ITK region grower:

QmitkRegionGrowingView.h

Add the private method:
\snippet QmitkRegionGrowingView.h itkimageprocessing

QmitkRegionGrowingView.cpp

Add includes:
\snippet QmitkRegionGrowingView.cpp cpp-includes

DoImageProcessing():
\snippet QmitkRegionGrowingView.cpp cpp-doimageprocessing

And add the new method:
\snippet QmitkRegionGrowingView.cpp cpp-itkimageaccess

Have fun using MITK!

If you meet any difficulties during your first steps, don't hesitate to ask on the MITK mailing list mitk-users@lists.sourceforge.net!
People there are kind and will try to help you.
