FilterDesignView is the largest settings panel in DISPLIB: it lets the user pick a filter type (low-, high-, band-pass or band-stop), a design family (cosine, Hamming, Blackman …), the cutoff frequencies, the transition bandwidth and the number of taps, preserves the resulting FilterKernel in a QSettings path and renders the magnitude (and optional group-delay / phase) response in a FilterPlotScene that updates while the user drags the spinboxes. Designed filters are emitted as filterChanged signals consumed by the rtprocessing filter chain.
