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

        Try again with this code
        I had comment the problem spots in the last code.
        The new one is here
        "Vectorproblems":http://rghost.net/31386231

        pls

          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
              create object
              delete ClPresetLoadsTestValues
              appendat obj
              1 vectorsize and kapacitet = 1
              delete ClPresetLoadsTestValues

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

              here is my object

              @@ClPresetLoadsTestValues::ClPresetLoadsTestValues()
              {
              qDebug() << "create ClPresetLoadsTestValues";
              }

              ClPresetLoadsTestValues::ClPresetLoadsTestValues(int k, int m, int s)
              {
              this->kw = k;
              this->min = m;
              this->sec = s;
              qDebug() << "create ClPresetLoadsTestValues";
              }

              ClPresetLoadsTestValues::~ClPresetLoadsTestValues()
              {
              qDebug() << "delete ClPresetLoadsTestValues";
              }

              //set and getters
              @

              and my func to add the obj

              @void GlobalParams::addValuesToLoadsTestTemp(int kw, int min, int sec)
              {
              ClPresetLoadsTestValues p(kw,min,sec);

              qDebug() << "try to append";
               qDebug() << this->presetVector.size() << " vektorstorlek"; //IT crashes here
              
              if (this->presetVector.isEmpty())
                  qDebug() << "Empty";
               else
                  qDebug() << "SIZE " << presetVector.size() ;
              
              presetVector.append(p);
               qDebug() << "appendad";
              

              }

                Can you make another tarball?

                  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.

                        Please provide a

                        • complete
                        • compilable
                        • minimal

                        test case.

                        leave out

                        • intermediate object file (*.o)
                        • autogenerated stuff from moc and uic (moc_.cpp, ui_.h)
                        • Qt Creator user data (*.pro.user)
                        • the final executable

                        You're more likely to get an answer if the fellows trying to help here in the forums do not need to guess how to set up a correct test case and a project file.

                          Here is a full tested version with compiling.

                          I uploaded a small ex earlier

                            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.

                              Unfortunately I can spend some time on it right now, but the archive is no longer available. Do you mind uploading it again, please?

                                I got it solved and it had a Nullpointer in another place so this worked fine but some dependent functions made some errors to this.
