在D3-V3中工作的代码在D3-V4中不起作用

Question

我必须在d3-v4中禁用鼠标左键的平移，它应该只使用鼠标右键平移。我的下面的代码是在d3-v3中工作但不在v4中

        this.zoomListener = d3.zoom().on("start", this.zoomstart.bind(this)).on("zoom", this.zoom.bind(this)).on("end", this.zoomend.bind(this));
        const eventProxy = (fn: any) => {
            return () => {
                // Enable events if enableEvents=== true
                if (d3.event.which === 3) {
                    fn.apply(this, arguments);
                }
            };
        };
        this.parentSvg.call(this.zoomListener).on("dblclick.zoom", null);
        const mouseDownTarget = this.parentSvg.on("mousedown.zoom");
        this.parentSvg.on("mousedown.zoom", eventProxy(mouseDownTarget));

有人知道如何在V4中这样做吗
