Hello Stefan, I am begging a pardon, I've reread my answer and discovered a typo. I wrote: > I would like to call your attention no QApplication and > QApplication::exec should be called by your code directly. > Qt-edition > ROOT takes care to initialize the Qt system properly for you. The "NOT" was missed. The real statement should read, " . . . > QApplication::exec should NOT be called by your code directly. . . ."
