QT is a beginner. He reads books and makes little things by himself. Recently, a sudden whim, I want to make a little clever, beautiful interface a little forgotten as the desktop. After thinking for a long time, I found that the aero Effect of Vista/win7 was good. Besides, I am using win7 now. So I went online and found out how to make the aero effect by using QT. After Google finally found the function and usage. So we made a simple aero special effect window.
