9.Net Micro Framework研究—窗体控件

原文地址：https://blog.csdn.net/yefanqiu/archive/2007/11/15/1887238.aspx 

试验平台：.Net Micro Framework 模拟器

在Microsoft.SPOT.Presentation.Controls命名空间里，也就如下几个控件（姑且称为控件吧），Panel、StackPanel、Text、TextFlow、Image、ListBox、ScrollViewer 其中仅有Panel、Text、Image控件完成度相对较好，其他的实现并不完整，甚至只是一个空接口。

下面是测试代码：

using System;

using Microsoft.SPOT;

using Microsoft.SPOT.Input;

using Microsoft.SPOT.Presentation;

using Microsoft.SPOT.Presentation.Controls;

using Microsoft.SPOT.Presentation.Media;

using Microsoft.SPOT.Presentation.Shapes;

namespace MFWindow

{

    public class Program : Microsoft.SPOT.Application

    {

        public static void Main()

        {

            //创建窗体

            WindowsDrawing win = new WindowsDrawing();

            //程序运行

            new Program().Run(win);

        }

        internal sealed class WindowsDrawing : Window

        {

            public WindowsDrawing()

           {

                this.Width = SystemMetrics.ScreenWidth;

                this.Height = SystemMetrics.ScreenHeight;

                //可设置显示方向（水平，垂直）

                //StackPanel panel = new StackPanel(Orientation.Vertical);

                StackPanel panel = new StackPanel(Orientation.Horizontal);

                //设置对象堆叠的方式

                panel.HorizontalAlignment = HorizontalAlignment.Left;

                panel.VerticalAlignment = VerticalAlignment.Top;

    this.Child = panel;

                //Text控件

                Text txt = new Text(Resources.GetFont(Resources.FontResources.small), "yefan");

                txt.Width = 100;

                txt.Height = 30;

                txt.ForeColor = Colors.Green;

                panel.Children.Add(txt);

                //TextFlow控件 不支持滚动条，实现还不完整

                TextFlow txtf = new TextFlow();

                txtf.ScrollingStyle = ScrollingStyle.LineByLine;

                txtf.TextAlignment = TextAlignment.Left;

                txtf.Height = 200;

                txtf.Width = 50;

                for (int i = 0; i < 10; i++)

                {

                    txtf.TextRuns.Add(new TextRun("yefan123", Resources.GetFont(Resources.FontResources.small), Colors.Blue));

                    //注意:换行这么写，可不是\r\n

                    txtf.TextRuns.Add(TextRun.EndOfLine);

                    txtf.TextRuns.Add(new TextRun("yefan456", Resources.GetFont(Resources.FontResources.small), Colors.Red));

                    txtf.TextRuns.Add(TextRun.EndOfLine);

                    txtf.TextRuns.Add(new TextRun("yefan789", Resources.GetFont(Resources.FontResources.small), Colors.Green));

                    txtf.TextRuns.Add(TextRun.EndOfLine);

                }

                panel.Children.Add(txtf);

                //image

                Image img = new Image();

                img.Bitmap = Resources.GetBitmap(Resources.BitmapResources.yfmvp);

                panel.Children.Add(img);

                //ListBox 仅实现了一个空接口

                ListBox lst = new ListBox();

                lst.Font = Resources.GetFont(Resources.FontResources.small);

                lst.Items.Add(new ListBoxItem());

                //panel.Children.Add(lst);

                //ScrollViewer 仅实现了一个空接口

                ScrollViewer sv = new ScrollViewer();

                sv.Width = 30;

                sv.Height = 50;

                //panel.Children.Add(sv);

                //sv.Child = txtf;

            }

        }

    }

}

目前版本的MF对TCP协议栈支持也并不完善（对串口也谈不上完善，毕竟不支持奇偶校验、停止位设置），Digi的以太网口是加入了自己的处理方案，明年二月份微软将要发布的MF V3.0版，就已经完全支持TCP了，到时候MF最理想的应用也许就是通信转换了。

从本篇内容中可以看出，微软MF之旅尚在出发点不远的地方，MF研发人员任重而道远啊！
