[SOLVED]Qvector Problem instansiate Thanks ALL

toho71

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

p-himik

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

giesbert

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

toho71

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

toho71

Here is not the TAR file to test

p-himik

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

toho71

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;
}@

toho71

copy and paste is the to magic words
Ok now it works again.

I have to look in my header prj to and see if this is the magic case.

toho71

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?

toho71

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

p-himik

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

toho71

Here it is

the two files with this problem
"myFiles":http://rghost.net/31396481

goetz

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.

toho71

Here is a full tested version with compiling.

I uploaded a small ex earlier
"MyApp":http://rghost.net/31409351

toho71

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.

goetz

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.
