[Insight-users] CMAKE command to link Fltk (fluid) in a code

[Luis Ibanez]

Hi Alexandre,


CMake offers you a much better way of managing the .fl
files from fluid. In fact, CMake is fully FLTK-aware.


Please look at the Tutorial sessions

   http://www.itk.org/HTML/Tutorials.htm

in particular to

    "ITK and Graphical User Interface"
http://www.itk.org/CourseWare/Training/GettingStarted-IV.pdf

where you will find instructions on how to use
ITK along with FLTK or with Qt, and how to setup
CMakeLists.txt files using ITK + FLTK.


You will find multiple examples of ITK+FLTK
configurations in the InsightApplications checkout.


Here is for example, an extract from the CMakeLists.txt
file of the GaussianFilter demo application available at
InsightApplications:


-----------------------------------------------------

INCLUDE_DIRECTORIES(
   ${InsightApplications_SOURCE_DIR}/Auxiliary/FltkImageViewer
   ${InsightApplications_BINARY_DIR}/Auxiliary/FltkImageViewer
   ${InsightApplications_SOURCE_DIR}/GaussianFilter
   ${InsightApplications_BINARY_DIR}/GaussianFilter
)

SET(GaussianFilter_SRCS
   liFilterConsole.cxx
   liFilterConsoleBase.cxx
   GaussianFilter.cxx
   )

ADD_GUI_EXECUTABLE(GaussianFilter   "${GaussianFilter_SRCS}")

FLTK_WRAP_UI(GaussianFilter liFilterConsoleGUI.fl)

ITK_DISABLE_FLTK_GENERATED_WARNINGS(liFilterConsoleGUI.fl)

TARGET_LINK_LIBRARIES(GaussianFilter
                        ITKFltkImageViewer ITKIO ITKBasicFilters)

-----------------------------------------------------

The CMake command:

              FLTK_WRAP_UI()

is the one that knows what to do with the .fl fluid files.
It will take care of generating the .cxx and .h files for
your and it will add them to the list of files to be compiled.



Please let us know if you have further questions.


    Thanks


      Luis
