Get a array inside slot

[Helson]

Hello, I have a combobox connected on a slot.

connect(mpCourseComboBox, SIGNAL(currentIndexChanged(int)), &dlgPublicar, SLOT(mySlot(int)));

I need use the myVector inside the dialog class.

ClassOne::methodOne{
QVector<QString> myVector;
myVector.append("info");
}

The class below is a dialog with combobox widget

DialogClass::mySlot(int index){
//I need get myVector here
}

I try declare myVector in .h public and

ClassOne CO;
co.myVector; //but here it is null

Please.
Thanks in advance!

Hi

1. QVector<QString> myVector; will be deleted as soon as methodOne ends.
   you should move it to ClassOne.h as a member of the class;

2. the combox currentIndexChanged cant take QVector
   so it would be best if dialog already know it.

So you can add a function to DialogClass to set the list;
void DialogClass::SetVector(QVector<QString> *Vector) {
Myvec = Vector ; // keep a pointer to it.
};

AND also add a new member variable to DialogClass.h
QVector<QString> *Myvec=NULL;

then in DialogClass::mySlot(int index){
if (Myvec) {
....
}
}

// in ClassOne/main
DialogClass *DC=new DialogClass ();
DC->SetVector(myVector);

Note: this is not the best way to do it. it would be via DialogClass constructor as then
it would have vector from birth.

Thank you so much!!!

DC->SetVector(&myVector);

Oh I forgot &. good spotted.
You are welcome.

@mrjj
int size = myVector->size(); //Return 1

int size = *myVector->size(); //Compilation error

myVector is an QVector<QVector<QVector<QString>>>

And it's have some data like:

QVector(QVector(
QVector("XXX", "XXX", "XXX", "A") ,
QVector("XXX", "XXX", "XXX", "B") ,
QVector("XXX", "XXX", "XXX", "C"),
QVector("XXX", "XXX", "XXX", "D") ,
QVector("XXX", "XXX", "XXX", "E") ,
QVector("XXX", "XXX", "XXX", "F"),
QVector("XXX", "XXX", "XXX", "G")
) )

And I need iterate...
if it's not asking too much, can you help me?

Hi
it seems like you add a QVector to the QVector.
And the added QVector, has Many QVectors?
List of list of list :)
Can we talk about the data as this is pretty complex to handle :)
Will each inner list always be the same
"XXX", "XXX", "XXX", "A"
"XXX", "XXX", "XXX", "B"
"XXX", "XXX", "XXX", "C"
4 strings?

The list have another values, but i need this structure to do this.

myVector[0][0] [0]="XXX" [1]="XXX2", [2]="XXX3" //3dr dimension have the data
myVector[0][1] [0]="XXX" [1]="XXX2", [2]="XXX3"
myVector[0][2] ...
myVector[0][3] ...

myVector[1][0] ...
myVector[1][1] ...
myVector[1][2] ...
myVector[1][3] ...

myVector[2][0] ...
myVector[2][1] ...
myVector[2][2] ...
myVector[2][3] ..
