小菜的系统框架界面设计-灰姑娘到白雪公主的蜕变（工具条OutLookBar）

灰姑娘本身也有自已的优点，但是却可能因为外貌不讨人喜欢，要变成白雪公主却需要有很多勇气和决心去改变自已：

有一颗善良的心
讨人喜爱的外貌

--蜕变-->

我这里讲的是一个工具条的蜕变过程，用”灰姑娘到白雪公主蜕变”这个比喻不知道是否合理？还恳请高人讨教。

工具条控件提供了一种类似Outlook方式的导航菜单，用来切换各种业务窗口，用上这个控件，肯定为你的程序增色不少,这个工具条的优点是可以上下划动，很灵活，这个是我需要采用的；

缺点是只能跟传统的系统界面进行匹配，提供外接设置的接口比较少，并且它没有任何的换肤功能, 如果用到具有换肤功能的系统中，它真变成了“土里土气的灰姑娘”。

现状

现在来看传统的OutLookBar的长相,是不是有些土里土气?

蜕变后

现在我要让它变成白雪公主，对它进行改造，添加支持换肤功能(背景色根据需要设置)...这样就秀气多了大声笑 , 来看它的蜕变过程，如下：

(1)Office2007Blue:

文字中间对齐,Office鼠标经过效果:

文字向左对齐,Office鼠标经过效果:

Office鼠标经过效果：

另一种背景色，这个可以通过设置调整:

鼠标点下时效果:

(2)Office2007Silver:

鼠标经过时效果:

正常状态:

如何蜕变?

另一种OutLook的效果，它做得非常漂亮，请参考网站 www.codeproject.com上的一篇介绍OutLook样式的导航条的文章《A Serious Outlook Style Navigation Pane Control》,具体图示：

正常效果鼠标经过效果鼠标点击效果

它的两种样式:

Office2007Blue:

Office2007Silver:

这个控件的优点很明显:很清新，美观，也灵活;至于缺点，我总感觉它不能够上下划动，拉动时划动距离还是有限的，个人总感觉还是我前面提到的那种上下划动比较灵活。

所以，我根据这个控件的设计原理，对前面讲到的能上下划动的工具条控件做改善。

新特性:

添加换肤接口,能够灵活扩展皮肤模板
添加鼠标经过，按下(hover,Press)导航按钮时Office效果

具体设计步骤：

设计一个基本皮肤模板类:NaviColorTableOffice.cs

参考源码：

      public override Color PopupBandBackground { get { return Color.FromArgb(240, 241, 242); } }
   }
}

(4). 如何去实现渲染这个工具栏上的按钮，把它们加工得更漂亮一点？

我是这样做的，设计一对控件进行渲染的类：NaviButtonRendererOffice2007.cs,由它来实现对控件进行重加工，参考如下:

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace UtilityLibrary.Common
{
    public class NaviButtonRendererOffice2007
    {
        NaviColorTableOffice colorTable;
        public NaviButtonRendererOffice2007()
        {
            // Use by default the blue colors, override this with the property ColorTable
            colorTable = new NaviColorTableOffice2007Blue();
        }
        /// <summary>
        /// Gets or sets the table of colors
        /// </summary>
        public NaviColorTableOffice ColorTable
        {
            get { return colorTable; }
            set { colorTable = value; }
        }

        /// <summary>
        /// Draws the background gradients of an Button
        /// </summary>
        /// <param name="g">The graphics surface to draw on</param>
        /// <param name="bounds">The bounds that the drawing should apply to</param>
        public  void DrawBackground(Graphics g, Rectangle bounds, ControlState state, InputState inputState)
        {
            Color[] endColors = new Color[1];

            if ((state == ControlState.Normal) && (inputState == InputState.Normal))
            {
                endColors = new Color[] { ColorTable.ButtonLight, ColorTable.ButtonDark, 
                                ColorTable.ButtonHighlightDark, ColorTable.ButtonHighlightLight };
            }
            else if ((state == ControlState.Normal) && (inputState == InputState.Hovered))
            {
                endColors = new Color[] { ColorTable.ButtonHoveredLight, ColorTable.ButtonHoveredDark, 
                                ColorTable.ButtonHoveredHighlightDark, ColorTable.ButtonHoveredHighlightLight };
            }
            else if ((state == ControlState.Active) && (inputState == InputState.Normal))
            {
                endColors = new Color[] { ColorTable.ButtonActiveLight, ColorTable.ButtonActiveDark, 
                                ColorTable.ButtonActiveHighlightDark, ColorTable.ButtonActiveHighlightLight };
            }
            else if ((inputState == InputState.Clicked)
               || ((state == ControlState.Active) && (inputState == InputState.Hovered)))
            {
                endColors = new Color[] { ColorTable.ButtonClickedLight, ColorTable.ButtonClickedDark, 
                                ColorTable.ButtonClickedHighlightDark, ColorTable.ButtonClickedHighlightLight };
            }

            float[] ColorPositions = { 0.0f, 0.62f, 0.62f, 1.0f };

            ExtDrawing.DrawGradient(g, bounds, endColors, ColorPositions);

            using (Pen p = new Pen(ColorTable.DarkBorder))
            {
                g.DrawLine(p, bounds.Left, bounds.Top, bounds.Right, bounds.Top);
            }
            
        }

        /// <summary>
        /// Draws text on a graphics canvas
        /// </summary>
        /// <param name="g">The graphics surface to draw on</param>
        /// <param name="bounds">The bounds of the text</param>
        /// <param name="font">The font of the text</param>
        /// <param name="text">The text to draw</param>
        /// <param name="rightToLeft">Rigth to left or left to right layout</param>
        public  void DrawText(Graphics g, Rectangle bounds, Font font, string text, bool rightToLeft)
        {
            using (Brush brush = new SolidBrush(ColorTable.Text))
            {
                if (rightToLeft)
                {
                    TextRenderer.DrawText(g, text, font, bounds, ColorTable.Text,
                       TextFormatFlags.SingleLine | TextFormatFlags.VerticalCenter | TextFormatFlags.EndEllipsis
                       | TextFormatFlags.Right | TextFormatFlags.RightToLeft);
                }
                else
                {
                    TextRenderer.DrawText(g, text, font, bounds, ColorTable.Text,
                       TextFormatFlags.SingleLine | TextFormatFlags.VerticalCenter | TextFormatFlags.EndEllipsis);
                }
            }
        }
    }
}

我们直接调DrawBackground(Graphics g, Rectangle bounds, ControlState state, InputState inputState) 对按钮进行重绘就可以实现了。

那么如何达到换肤的功能?关键是对象NaviColorTableOffice,其他的皮肤类都继承它，这里是通过多态的方式进行实例化对象。

请参考StyleManager.cs,这是一个皮肤制造工厂,通过反射机制去动态实例化皮肤对象:

using System;
using System.Collections.Generic;
using System.Text;
using UtilityLibrary.Enums;

namespace UtilityLibrary.Common
{
    class StyleManager
    {
        public static NaviColorTableOffice GetOffice2007ColorTable(Style style)
        {
            string className = "UtilityLibrary.Common.NaviColorTable" + style.ToString();
            Type type = Type.GetType(className);
            if (type != null)
            {
                return (NaviColorTableOffice)Activator.CreateInstance(type);
            }
            return null;
        }
    }
}

我添加一个enum类型作为皮肤的样式，这里只设计三个样式。

namespace UtilityLibrary.Enums
{
    public enum Style
    {
        Office2007Blue,
        Office2007Silver,
        Office2007Black
    }
}

最后关键的一步到了，在OutlookBar.cs实现接口IStyle：

#region OutlookBar class
    [ToolboxBitmap(typeof(UtilityLibrary.WinControls.OutlookBar), 
    "UtilityLibrary.WinControls.OutlookBar.bmp")]
    public class OutlookBar : System.Windows.Forms.Control,IStyle
    {

如下代码是客户端设置皮肤的关键:

#region IStyle 成员
        public void SetStyle(Style style)
        {
            rendererOffice2007.ColorTable = StyleManager.GetOffice2007ColorTable(style);
            this.Refresh();
        }

        private Style _style = Style.Office2007Blue;
        public Style Style
        {
            get
            {
                return _style;
            }
            set
            {
                _style = value;
                SetStyle(_style);
            }
        }

所以我们在客户端设计某个皮肤时，可以这样做:

OutlookBar outlookBar1 = new OutlookBar();
outlookBar1.SetStyle(Style.Office2007Blue);//设置Office2007Blue皮肤
outlookBar1.OfficeStyle = true;//设置Office效果,主要是mouse经过，点下时的效果

最终的整体效果

总结

整个过程下来，主要做的工作:

设计模板
设计换肤接口
渲染按钮控件
换肤接口调用

经过这几个工序，对这个灰姑娘进行“整容”，“美化”的一系列过程，它就变成了白雪公主啦，不过因为它先天不足，只能说差不多过得去。

上传改善后的控件供大家试用吧,分享快乐吐舌笑脸 ,如果感觉比原来的好,记得给小弟点评一下喔~~~

如何蜕变?

具体设计步骤：

设计一个基本皮肤模板类:NaviColorTableOffice.cs

2. 再做几个模板，继承皮肤基本类NaviColorTableOffice

(1). Office2007Blue

(2). Office2007Silver

(3). Office2007Black
