2D array in Qt: QVector or QList

[AIT RAI]

i want to creat a two-dimensional QVector of QLine which means in front of each line another line:

for(int i=0;i<symZqaq.size();i++)
{
QVector<QLineF> sym;
sym.append(L4);
sym.append(L5);
sym.append(L29);
sym.append(L25);
sym.append(L42);
sym.append(L26);
sym.append(L28);
sym.append(L31);
sym.append(L36);
sym.append(L44);
symZqaq.append(sym);
}
for(int i=0;i<symZqaq.size();i++)
{
for(int j=0;j<symZqaq[i].size();i++)
{
symZqaq.append(L9);
symZqaq.append(L12);
symZqaq.append(L24);
symZqaq.append(L30);
symZqaq.append(L27);
symZqaq.append(L43);
symZqaq.append(L7);
symZqaq.append(L2);
symZqaq.append(L6);
symZqaq.append(L3);
}
}
the problem is in last loop for erreur : no matching function for call to 'QVector<QVector<QLineF> >:ush_back(QLineF&)'
symZqaq.push_back(L9);

any help plz

no matching function for call to 'QVector<QVector<QLineF> >:: push_back(QLineF&)'

"symZqaq" is a QVector of QVectors, not a QVector of QLines. You can't push a QLine onto symZqaq, only a QVector< QLine >. You did it correctly in the first loop. Use the same method in the nested loop.
