I don't want to do it for you, but here's my advice: processSamples should just copy the samples into some sort of queue, which should always contain the most recent X samples (where X is the FFT size or some multiple of that). Then, when ::Draw() wishes to draw, it should take the most recent FFT-size samples, copy them, window them, FFT them, then draw. If the input samples haven't changed since the previous draw, it could reuse the previous results. This method would have the added advantage of reducing the audio thread CPU use (and putting it in the UI thread).
