How do I create an Object at runtime?

[Cayan]

I'm trying to develop an option where according to some options the Dialog gets resized and some new objects appear on screen. What I'm trying is:

label1 = new QLabel(this);
label1->setObjectName(QString::fromUtf8("label1"));
label1->setProperty("text", "Direction:");
label1->setProperty("geometry", QRect(10, 70, 43, 13));

label1 = new QLabel(this);
label1->setObjectName(QString::fromUtf8("label1"));
label1->setProperty("text", "Direction:");
label1->setProperty("geometry", QRect(10, 70, 43, 13));

To copy to clipboard, switch view to plain text mode 

This is from my last try, I've also attempted to do it with directly property changes, like: label1->setText("Direction:");
It does not return any error... it simple does nothing...
I don't wanna manage hidden objects for this, it is far better to make them dynamically but something is happening and I don't know what...
