21、WindowProperties

WindowProperties

该项目展示了一个简单的Windows应用程序，该程序使用几个属性（特性）来显示其主窗口的大小。显示内容随用户重设窗口大小而自动更新。

(1) 创建项目

创建WPF Application项目：WindowProperties。

(2) 设计界面

 

<Window x:Class="WindowProperties.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="Window Properties" Height="150" Width="300" SizeChanged="Window_SizeChanged">

    <Grid>

        <Label Content="Width" Height="28" HorizontalAlignment="Left" Margin="12,12,0,0" VerticalAlignment="Top" Width="82" />

        <Label Content="Height" Height="28" HorizontalAlignment="Left" Margin="184,12,0,0" VerticalAlignment="Top" Width="82" />

        <TextBox Height="23" HorizontalAlignment="Left" Margin="12,58,0,0" Name="textBoxWidth" VerticalAlignment="Top" Width="82" />

        <TextBox Height="23" HorizontalAlignment="Left" Margin="184,58,0,0" Name="textBoxHeight" VerticalAlignment="Top" Width="82" />

    </Grid>

</Window>

(3) 修改MainWindow.xaml.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

 

namespace WindowProperties

{

    /// <summary>

    /// Interaction logic for MainWindow.xaml

    /// </summary>

    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();

            sizeChanged();

        }

 

        private void sizeChanged()

        {

            textBoxWidth.Text = this.ActualWidth.ToString();

            textBoxHeight.Text = this.ActualHeight.ToString();

        }

 

        private void Window_SizeChanged(object sender, SizeChangedEventArgs e)

        {

            sizeChanged();

        }

    }

}

(4) 运行测试
