如何在wpf中创建自定义窗口chrome？

Question

如何为WPF窗口创建基本的自定义窗口镶边,不包括关闭按钮,仍然是可移动和可调整大小的窗口？

Answer 1

你设置你的窗口WindowStyle="None",然后建立自己的窗口界面.您需要构建自己的Min/Max/Close/Drag事件处理程序,但仍会保留Resizing.

例如:

<Window 
    WindowState="Maximized" 
    WindowStyle="None"
    WindowStartupLocation="CenterScreen"
    MaxWidth="{Binding Source={x:Static SystemParameters.WorkArea}, Path=Width}"
    MaxHeight="{Binding Source={x:Static SystemParameters.WorkArea}, Path=Height}"
>

    <DockPanel x:Name="RootWindow">
        <DockPanel x:Name="TitleBar" DockPanel.Dock="Top">
            <Button x:Name="CloseButton" Content="X"
                    Click="CloseButton_Click"                 
                    DockPanel.Dock="Right" />
            <Button x:Name="MaxButton" Content="Restore" 
                    Click="MaximizeButton_Click"
                    DockPanel.Dock="Right" />
            <Button x:Name="MinButton" Content="Min"
                    Click="MinimizeButton_Click"
                    DockPanel.Dock="Right" />

            <TextBlock HorizontalAlignment="Center">Application Name</TextBlock>
        </DockPanel>

        <ContentControl Content="{Binding CurrentPage}" />
    </DockPanel>

</Window>

这里是常见窗口功能的一些示例代码隐藏

/// <summary>
/// TitleBar_MouseDown - Drag if single-click, resize if double-click
/// </summary>
private void TitleBar_MouseDown(object sender, MouseButtonEventArgs e)
{
    if(e.ChangedButton == MouseButton.Left)
        if (e.ClickCount == 2)
        {
            AdjustWindowSize();
        }
        else
        {
            Application.Current.MainWindow.DragMove();
        }
 }

/// <summary>
/// CloseButton_Clicked
/// </summary>
private void CloseButton_Click(object sender, RoutedEventArgs e)
{
   Application.Current.Shutdown();
}

/// <summary>
/// MaximizedButton_Clicked
/// </summary>
private void MaximizeButton_Click(object sender, RoutedEventArgs e)
{
    AdjustWindowSize();
}

/// <summary>
/// Minimized Button_Clicked
/// </summary>
private void MinimizeButton_Click(object sender, RoutedEventArgs e)
{
    this.WindowState = WindowState.Minimized;
}

/// <summary>
/// Adjusts the WindowSize to correct parameters when Maximize button is clicked
/// </summary>
private void AdjustWindowSize()
{
    if (this.WindowState == WindowState.Maximized)
    {
        this.WindowState = WindowState.Normal;
        MaximizeButton.Content = "1";
    }
    else
    {
        this.WindowState = WindowState.Maximized;
        MaximizeButton.Content = "2";
    }

}

.NET 4.5添加了一个新类,大大简化了这一点.

该WindowChrome类可让您的Windows Presentation Foundation(WPF)的内容延伸到这通常是保留给操作系统的窗口管理器窗口的非客户区.

你可以在这里找到一个教程.

这是一个简短的示例用法.

我刚刚在.net 4.5中使用了下面的示例，它工作得很好。有趣的是，它为点击事件使用了后面的代码作为资源字典。您所要做的就是在app.xaml文件中引用资源字典，然后为Window指定样式CustomWindowStyle。这是从http://www.eidias.com/blog/2014/1/27/restyle-your-window偷来的。

<ResourceDictionary x:Class="WpfApp7.WindowStyle"

                                    Width="15"

                                <Button x:Name="btnRestore"

                                <Button x:Name="btnMinimize"
                                    Width="15"
                                    Margin="5"
                                    VerticalContentAlignment="Bottom"
                                    Click="MinimizeClick"
                                    Content="_"

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

对于后面的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;

namespace WpfApp7
{
    public partial class WindowStyle : ResourceDictionary
    {
        public WindowStyle()
        {
            InitializeComponent();
        }

        private void CloseClick(object sender, RoutedEventArgs e)
        {
            var window = (Window)((FrameworkElement)sender).TemplatedParent;
            window.Close();
        }

        private void MaximizeRestoreClick(object sender, RoutedEventArgs e)
        {
            var window = (Window)((FrameworkElement)sender).TemplatedParent;
            if (window.WindowState == System.Windows.WindowState.Normal)
            {
                window.WindowState = System.Windows.WindowState.Maximized;
            }
            else
            {
                window.WindowState = System.Windows.WindowState.Normal;
            }
        }

        private void MinimizeClick(object sender, RoutedEventArgs e)
        {
            var window = (Window)((FrameworkElement)sender).TemplatedParent;
            window.WindowState = System.Windows.WindowState.Minimized;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("Hello!");
        }
    }
}

Answer 4

这是一个简单的解决方案，它看起来与默认的 Windows 10 按钮非常相似，它只是为符号使用相同的字体：

<StackPanel Orientation="Horizontal" VerticalAlignment="Top" WindowChrome.IsHitTestVisibleInChrome="True">
<Button Click="Minimize_Click" Content="&#xE949;" FontFamily="Segoe MDL2 Assets" FontSize="10" Padding="15,15,15,5" Background="Transparent" BorderBrush="Transparent" />
<Button Click="Maximize_Click" FontFamily="Segoe MDL2 Assets" FontSize="10" Padding="15,10" Background="Transparent" BorderBrush="Transparent">
    <Button.Style>
        <Style TargetType="{x:Type Button}">
            <Setter Property="Button.Content" Value="&#xE739;" />
            <Style.Triggers>
                <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}, Path=WindowState}" Value="Maximized">
                    <Setter Property="Button.Content" Value="&#xE923;" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </Button.Style>
</Button>
<Button Click="Close_Click" Content="&#xE106;" FontFamily="Segoe MDL2 Assets" FontSize="10" Padding="15,10" Background="Transparent" BorderBrush="Transparent" />
</StackPanel>

Answer 5

以下是您需要采取的方法的概述：

• 设置WindowStyle="None"做你自己的UI。
• 用于WindowChrome.CaptionHeight获得标准标题栏拖动/双击/摇动行为并设置WindowChrome.IsHitTestVisibleInChrome="True"按钮以使其可单击。
• 为您的按钮实现点击处理程序。
• 挂钩 Window.StateChanged 事件来处理最大化/恢复更改并更新您的 UI。您不能假设每个人都使用标题栏按钮来最大化和恢复。这可以通过键盘快捷键（Win+Up/Win+Down）或双击标题栏来实现。
• 最大化时，窗口的 7 像素会被四面八方切断。要解决此问题，我们需要挂钩 WM_GETMINMAXINFO 以提供正确的最大化位置。
• 您需要重新实现窗口边框以提供不同背景的对比度。
• 使用 <Path> 渲染标题栏图标，以便它们在不同的 DPI 下看起来不错。
• 根据窗口是否处于活动状态更改标题栏的外观，以向用户指示哪个窗口具有焦点。

全文有点长；我在这篇博文中通过代码示例详细介绍了它们。
