addToolBar, but only once please

Hello!

With Qt4, is there a way to make sure, that this toolBar

Code:

---

toolBarKunden = new QToolBar(this);
setObjectName(QString::fromUtf8("toolBarKunden"));
addToolBar(Qt::TopToolBarArea, toolBarKunden);
setWindowTitle(QApplication::translate("Erpel", "toolBarKunden", 0, QApplication::UnicodeUTF8));

---

will be created only once?

Something like

Code:

---

if (!toolBarKunden)
{ 
    // createToolBar ...
}

---

Thanks in advance,

Guenther

It's called C++. :) Did you remember to initialize the pointer?
