Re: memcpy with 64 bit

Even on 32 bits, the recommended way is to use a QTOpenGLVisualContext and CoreVideo, not QuickDraw and upload the texture yourself. Unfortunately there is no equivalent in 64 bits yet. But if your need are just to draw the movie, you should use a QTMovieView which do this for you. And if you

Notification based toolbar design pattern

My app toolbar design pattern is as follows. My question concerns the nature of this design. 1. The App has four or five window subclasses, each with separate, dynamic, toolbars. 2. Most of the toolbar items are views. 3. A toolbar controller factory class generates instances of toolbars for a
