    Ok, once again, check if constructor of GlobalParams is called, add there qDebug()<<"anything";

      It's the first thing I do in my program.

      I got a lot of parameters in that object that I use in other places so thats no problem.

        Please provide a small, complete, compilable and runnable sample program. We can have a look if and where it crashes ourselves then.

          Now I'm back to my Work and will send a small application with this Vector problem.
          I have put some QDebug lines in the code to:

          But where could I upload the program

            I think that any file sharing hosting will be suitable. For example try http://rghost.net/

              look for a file hoster (e.g. gitorious.org, but you need a logon) or any other

                I have discovered a problem know that is a little confusing.

                When I try to append a Object or a struct thats not in the class where the vector is the program crashes but when I put a struct inside the class and append this to the vector it works fine

                    Your code works without any crashes. I didn't do any changes though.

                        toho71 either you have to read more about C++ or you did horrible typo. Here it is:
                        @myClass::~myClass()
                        {
                        delete this;
                        }@

                            in my testcase i do like this in my constructor

                            @GlobalParams::GlobalParams()
                            {
                            testRunning(false);

                            qDebug() << presetVector.isEmpty();
                            qDebug() << presetVector.size() << " vectorsize  and kapacitet =" << presetVector.capacity();
                            
                            //Create a tempobject for test
                            ClPresetLoadsTestValues p(10,10,10);
                            
                            qDebug() << "create  object ";
                            
                            presetVector.append(p);
                            qDebug() << "appendat obj";
                            qDebug() << presetVector.size() << " vectorsize  and kapacitet =" << presetVector.capacity();
                            

                            }@

                            and I got this text in my consol

                            true
                            0 vectorsize and kapacitet = 0
                            create ClPresetLoadsTestValues

                            delete ClPresetLoadsTestValues

                            And later when I try to add a ClPresetLoadsTestValues my program crashes and NO i don't delete the object.

                                it gonna be big with many files but maybe only the files in the spec region and it will not compile.
                                I'll try

                                  You should provide only source files. Do not include object files (and autogenerated moc_, ui_, qrc_*) in the tarball.

                                          it works very well to append objects when I instantiates the object globalParam but later when I try to append some new objects later in the program it seems like the vector isn't there.
