Hi guys,
I wrote a tiny class for delaying splash screen in C++ but when I
tired to re-write it in python it didn't work!
I got "AttributeError TeSplashScreen object has no attribut
QFrate" although TeSplashScreen inherited from QFrame
Could you please help me, I'm still a newbie in PyQt and Python.
