A patch to fix part of the issue

This patch makes it so the generated C++ commenting style selection actually works now.

Did a quick review and found a few issues: 
> Settings aren't actually saved
1. works 
> Generated code still uses // comments instead of /* */ when that style is selected.

2. The generated comments in // style for example on classes looks like
  /// 
  /// class SDL_RWops

and for  methods like
  /// 
  /// Set the value of type
  /// @param new_var the new value of type
  void setType (Uint32 new_var)   {

in /* */ mode for classes 

  /** 
   * class SDL_RWops
   */

but for methods 

/*  */
/* Methods */
/*  */

which should be 

/**
  * Methods
 */

There may be more issues, which could be verified by opening the code generator test case   'test/test-COG.xmi' from the umbrello source and generating code with it.

2. Please follow topic 12. of CODING-STYLE from the umbrello source eg. 
if (...) {
        ...
} else { 
     .... 
}

3. If possible use 'git format-patch' to generate the patch to have a complete patch header, which could be easily applied with 'git am'.

Thank you for the bug report.

As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists.

If this bug is no longer persisting or relevant please change the status to resolved.

1. Apply patch https://bugs.kde.org/attachment.cgi?id=96895 with review
   comments by Ralf Habacker addressed.
2. Fix generation of section comments:
   - In umbrello/umbrello.kcfg group "Code Generation" change Bool
     forceSections to writeSectionComments of type
     CodeGenerationPolicy::WriteSectionCommentsPolicy.
   - In umbrello/optionstate.h class CodeGenerationState change member
     forceSections to writeSectionComments of type
     CodeGenerationPolicy::WriteSectionCommentsPolicy.
   - In umbrello/codegenerators/codegenerationpolicy.{h,cpp},
     - add enum WriteSectionCommentsPolicy with values None,
       WhenNonEmpty, Always;
     - rename accessors {set,get}CodeVerboseSectionComments handling
       bool argument to {set,get}SectionCommentsPolicy handling arg of
       type WriteSectionCommentsPolicy, and manipulating
       Settings::optionState().codeGenerationState.writeSectionComments
       in lieu of the former forceSections;
     - change member `bool m_codeVerboseSectionComments` to
       `WriteSectionCommentsPolicy m_sectionCommentsPolicy`.
   - In umbrello/codegenerators/codegenerationpolicy.cpp adjust
     functions setDefaults and writeConfig to the UmbrelloSettings
     switchover from forceSections() to writeSectionComments().
   - In umbrello/codegenwizard/codegenoptionspage.ui change QCheckBox
     ui_forceSections to QComboBox ui_writeSectionComments with values
     "None", "When section is non empty", "Always".
   - In umbrello/codegenwizard/codegenoptionspage.cpp adjust constructor
     and function apply() to the codegenoptionspage.ui change.
   - In umbrello/codegenerators/codegenerator.{h,cpp},
     - change setForceSections(bool) to setSectionCommentPolicy with arg
       of type CodeGenerationPolicy::WriteSectionCommentsPolicy calling
       UMLApp::app()->commonPolicy()->setSectionCommentsPolicy(arg);
     - at getter forceSections() add TODO remark about changing return
       type to CodeGenerationPolicy::WriteSectionCommentsPolicy.
   - In umbrello/codegenerators/cpp/cppwriter.cpp :
     - Move setting of m_indentLevel from function writeHeaderFile to
       writeClassDecl so that class level comments are generated without
       indentation.
     - In functions writeSourceFile, writeAttributeDecls,
       writeAttributeMethods, writeConstructorDecls,
       writeConstructorMethods,
       - change test of forceDoc() to forceSections() when deciding
         whether to write section comments;
       - on generating section comments, change
           writeComment(QStringLiteral(" "), indnt, stream)
         to
           writeBlankLine(stream)
         in order to avoid ugly empty comments /*  */ in multi line
         comment mode.
     - In function writeHeaderAttributeAccessorMethods simplify call to
       writeAttributeMethods() by factoring the effective visibility
       into local `vis`.
