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!
