Csharp Winform 流程图 （一、定义接口）

一、创建接口 ,确定接下来流程创建的过程中我们需要使用的哪些方法及变量，同时为后续提供其他人员开发自定义节点图形做好基础。

 

1、基础接口定义：IBase.cs

    internal interface IBase
    {
        Control Owner { get; set; }
        string Id { get; set; }
        string Name { get; set; }
        int X { get; set; }
        int Y { get; set; }
        int Width { get; set; }
        int Height { get; set; }
        int Left { get; }
        int Top { get; }
        int Right { get; }
        int Bottom { get; }
        bool Drag { get; }
        bool Capture { get; }
        bool Selected { get; set; }
        bool Hovering { get; }
        bool ReadOnly { get; }
        Color BorderColor { get; set; }
        Point Loaction { get; }
        Size Size { get; }
        RectangleF ClientRectangleF { get; }
        Rectangle ClientRectangle { get; }
        Color BackColor { get; set; }
        string Text { get; set; }
        Font Font { get; set; }
    }

　　2、事件接口定义：IEvent.cs

    internal interface IEvent
    {
        void OnMouseDown(MouseEventArgs e);
        void OnMouseEnter(EventArgs e);
        void OnMouseLeave(EventArgs e);
        void OnMouseHover(EventArgs e);
        void OnMouseMove(MouseEventArgs e);
        void OnMouseUp(MouseEventArgs e);
        void OnMouseWheel(MouseEventArgs e);
        void OnMove(EventArgs e);
        void OnPaint(PaintEventArgs e);
        void OnPaddingChanged(EventArgs e);
        void OnMouseDoubleClick(MouseEventArgs e);
    }

　　3、拓展一部分事件接口定义：IEventCustom.cs

    internal interface IEventCustom
    {
        event EventHandler PointChange;
        bool HasPointChange();
        void OnPointChange(EventArgs e);
    }

　　4、流程控制接口定义：IMaster.cs

    internal interface IMaster
    {
        /// <summary>
        /// 是否允许拖动
        /// </summary>
        [Description("是否允许拖动")]
        bool Drag { get; }
        /// <summary>
        /// 节点图形集合
        /// </summary>
        [Description("节点图形集合")]
        List<IShape> Shapes { get; }
        /// <summary>
        /// 连线图形
        /// </summary>
        [Description("连线图形")]
        ShapeLinks ShapeLink { get; }
        /// <summary>
        /// Master的拥有者
        /// </summary>
        [Description("Master的拥有者")]
        Control Owner { get; set; }
        /// <summary>
        /// 缩放因子
        /// </summary>
        [Description("缩放因子")]
        float ScaleFactor { get; set; }
        /// <summary>
        /// 平移转换
        /// </summary>
        [Description("缩放因子")]
        PointF DefaultTranslate { get; }
        /// <summary>
        /// 平移转换偏量
        /// </summary>
        [Description("平移转换偏量")]
        PointF TranslateOffset { get; }
        /// <summary>
        /// 鼠标偏移量
        /// </summary>
        [Description("鼠标偏移量")]
        PointF MouseOffset { get; }
        /// <summary>
        /// 坐标转换
        /// </summary>
        /// <param name="pointF">需要被转换的坐标</param>
        /// <returns></returns>
        PointF Pto(PointF pointF);
        /// <summary>
        /// 坐标转换
        /// </summary>
        /// <param name="pointF">需要被转换的坐标</param>
        /// <returns></returns>
        PointF PointTo(PointF pointF);
        /// <summary>
        /// 坐标转换
        /// </summary>
        /// <param name="pointF">需要被转换的坐标</param>
        /// <returns></returns>
        PointF Pform(PointF pointF);
        /// <summary>
        /// 坐标转换
        /// </summary>
        /// <param name="pointF">需要被转换的坐标</param>
        /// <returns></returns>
        PointF PointFrom(PointF pointF);
        /// <summary>
        /// 节点连线数据集合
        /// </summary>
        [Description("连线数据集合")]
        List<Link> Links { get; }
        /// <summary>
        /// 节点连线坐标数据集合
        /// </summary>
        [Description("节点连线坐标数据集合")]
        List<LinkPoint> LinkPoints { get; }
        /// <summary>
        /// 鼠标悬停的图形
        /// </summary>
        [Description("鼠标悬停的图形")]
        Tuple<ShapeModule, MouseEventArgs> MouseHoverShape { get; }
        void DrawGrid(Graphics graphics, Rectangle area, int majorStep, int minorStep);
        void SetNotSelectedShapeAll(IShape shape = null);
    }

　　5、节点图形绘制接口定义：IShape.cs  继承 IBase

    internal interface IShape:IBase
    {
        string FromShapId { get; set; }
        ShapeType ShapeType { get; set; }
        Region ClientRegion { get; set; }
        PointF[] ClientRegionPointFs { get; set; }
        RectangleF ClientRegionRect { get; set; }
        Point MouseOffset { get; }
        Point[] MouseOffsets { get; }
        int BorderWidth {  get; }
        float ScaleFactor { get;set; }
        Image Image { get; set; }
        PointF TranslateOffset { get;  }
        RectangleF RectScale { get; }
        Point Centre { get; }
        PointF Pto(PointF pointF);
        PointF PointTo(PointF pointF);
        PointF Pform(PointF pointF);
        PointF PointFrom(PointF pointF);
        /// <summary>
        /// 当前实例的浅表副本 复杂属性（引用类型....）不适用
        /// </summary>
        /// <returns></returns>
        //IShape Clone();
    }
