mono跨平台GUI库-Eto

潜水很久，也不知道写些什么，就放点好玩的东西，目前.net虽然开源了，但对跨平台这块，还得依靠mono，之前在windows下作界面编程，用到的就是winform和wpf，mono虽然支持winform，可是在Linux下的表现就好像那时候的windows95通常。因此要么就用GTK#，GTK#是GTK+的绑定，GTK的那些文档看得头疼。因此就找到这个Eto。

两年前写过一个小工具，串口助手，很简单的，就拿它来作个演示，下面是先前的一个界面。

1.新建控制台项目

2.将项目属性输出类型改成Windows应用程序

3.NuGet添加

Install-Package Eto.Forms

Install-Package Eto.Platform.Gtk

Install-Package Eto.Platform.Windows

4.建立MainForm

1 public partial class MainForm : Form
2    {
3        public MainForm()
4        {
5             InitializeComponent();
6        }
7    }            

建立UI

 partial class MainForm
    {
        private void InitializeComponent()
        {
            var layout_left = new DynamicLayout { Padding = new Padding(10, 5, 5, 5), Spacing = new Size(5, 5), ClientSize = new Size(345, 426), MinimumSize = new Size(345, 426) };
            var layout_right = new DynamicLayout { Padding = new Padding(5, 5, 5, 5), Spacing = new Size(5, 5), ClientSize = new Size(180, 426), MinimumSize = new Size(180, 426) };

            var layout_serialPort = new DynamicLayout { Padding = new Padding(5, 15, 5, 5), Spacing = new Size(5, 5) };


            _textAreaIn = new TextArea() { BackgroundColor = Colors.Black, TextColor = Colors.SpringGreen, };
            _textAreaOut = new TextArea() { BackgroundColor = Colors.Black, TextColor = Colors.SpringGreen, };
            layout_left.AddAutoSized(new Label() { Text = "接收区" });
            layout_left.AddSeparateRow(new Panel() { Content = _textAreaIn, MinimumSize = new Size(345, 240), ClientSize = new Size(345, 240) });
            layout_left.AddAutoSized(new Label() { Text = "发送区" });
            layout_left.AddSeparateRow(new Panel() { Content = _textAreaOut, MinimumSize = new Size(345, 165), ClientSize = new Size(345, 165) });

            _comboBoxSerialPortName = new ComboBox();
            _comboBoxSerialBaudRate = new ComboBox();
            _comboBoxSerialDataBits = new ComboBox();
            _comboBoxSerialParity = new ComboBox();
            _comboBoxSerialStopBits = new ComboBox();

            _btnClear = new Button { Text = "清空收区" };
            _btnClear.Click += _btnClear_Click;
            _btnOpen = new Button { Text = "打开串口" };
            _btnOpen.Click += _btnOpen_Click;
            _btnSend = new Button { Text = "串口发送" };
            _btnSend.Click += _btnSend_Click;
            _checkBoxHex = new CheckBox{ Text = "是否Hex"};
            label7 = new Label();

            layout_serialPort.BeginVertical();
            layout_serialPort.BeginHorizontal();
            layout_serialPort.AddAutoSized(new Label() { Text = "端口号：" }, new Padding(0, 3));
            layout_serialPort.AddAutoSized(_comboBoxSerialPortName);
            layout_serialPort.EndBeginHorizontal();
            layout_serialPort.BeginHorizontal();
            layout_serialPort.AddAutoSized(new Label() { Text = "波特率：" }, new Padding(0, 3));
            layout_serialPort.AddAutoSized(_comboBoxSerialBaudRate);
            layout_serialPort.EndBeginHorizontal();
            layout_serialPort.BeginHorizontal();
            layout_serialPort.AddAutoSized(new Label() { Text = "数据位：" }, new Padding(0, 3));
            layout_serialPort.AddAutoSized(_comboBoxSerialDataBits);
            layout_serialPort.EndBeginHorizontal();
            layout_serialPort.BeginHorizontal();
            layout_serialPort.AddAutoSized(new Label() { Text = "效验位：" }, new Padding(0, 3));
            layout_serialPort.AddAutoSized(_comboBoxSerialParity);
            layout_serialPort.EndBeginHorizontal();
            layout_serialPort.BeginHorizontal();
            layout_serialPort.AddAutoSized(new Label() { Text = "中止位：" }, new Padding(0, 3));
            layout_serialPort.AddAutoSized(_comboBoxSerialStopBits);
            layout_serialPort.EndBeginHorizontal();
            //layout_serialPort.AddColumn();
            //layout_serialPort.AddColumn();

            layout_serialPort.EndBeginVertical();

            layout_right.AddAutoSized(layout_serialPort);
            layout_right.AddCentered(new Panel() { Content = _btnClear, ClientSize = new Size(164, 37), MinimumSize = new Size(164, 37) }, null, null, true);
            layout_right.AddCentered(new Panel() { Content = _btnOpen, ClientSize = new Size(164, 37), MinimumSize = new Size(164, 37) }, new Padding(0, 80, 0, 0), null, true);
            layout_right.AddCentered(new Panel() { Content = _btnSend, ClientSize = new Size(164, 37), MinimumSize = new Size(164, 37) }, new Padding(0, 10), null, true);
            layout_right.AddCentered(_checkBoxHex);
            layout_right.AddAutoSized(label7);

            var layout = new Splitter()
            {
                Panel1 = layout_left,
                Panel2 = layout_right,
                Orientation = SplitterOrientation.Horizontal
            };
            this.Content = layout;
            this.Title = "串口助手";
        }

       

      

        private TextArea _textAreaIn;
        private TextArea _textAreaOut;

        private ComboBox _comboBoxSerialPortName;
        private ComboBox _comboBoxSerialBaudRate;
        private ComboBox _comboBoxSerialDataBits;
        private ComboBox _comboBoxSerialParity;
        private ComboBox _comboBoxSerialStopBits;

        private Button _btnClear;
        private Button _btnOpen;
        private Button _btnSend;
        private CheckBox _checkBoxHex;
        private Label label7;
    }

class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
            new Application().Run(new MainForm());
        }
    }

Eto有如下布局类：

• Panel - Controls that subclass Panel, such as Window, GroupBox, Scrollable, etc allow you to specify a single child Content control
• TableLayout - Similar to how an HTML table works, with a single control per cell
• PixelLayout - Specify X,Y co-ordinates for the position of each control (from Upper-Left)
• DynamicLayout - Dynamic hierarchical horizontal and vertical layout

至关于控件容器，用于Control的摆放，下面就看看各个平台下的显示效果 ^_^

1.windows下：

2Ubuntu下：

3.最近有人在的玩树莓派：

下载地址：代码

比较简单，只是想说，咱dotNet跨平台仍是很好玩的哈~纯粹抛砖引玉哈。。。
