Question

因此，我构建了此示例应用程序，并使用了带有WPF和C＃的自定义WindowChrome。每次我尝试使用自己制作的按钮最大化窗口时，最大化窗口都会变得略微关闭吗？像是几个像素。发生什么事了？

<Window x:Class="TestApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:TestApp"
        mc:Ignorable="d"
        Title="TestApp"
        WindowStyle="None"
        WindowStartupLocation="CenterScreen"
        MinHeight="500" MinWidth="940">

    <WindowChrome.WindowChrome>
        <WindowChrome 
            ResizeBorderThickness="6"
            CaptionHeight="20"
            GlassFrameThickness="0"
            CornerRadius="0"
            />
    </WindowChrome.WindowChrome>

    <!-- Application -->
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="26" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <!-- WindowChrone Header -->
        <Grid Background="{StaticResource WindowChromeBrush}" Grid.Row="0">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="30"/>
                <ColumnDefinition Width="30"/>
                <ColumnDefinition Width="30"/>
            </Grid.ColumnDefinitions>
            <Button Grid.Column="0" Content="RelayC" />
            <Button Click="MinimizeWindow" Grid.Column="2" Style="{StaticResource WindowChromeButton}">
                <Image Source="{StaticResource window_minimize_icon}"/>
            </Button>
            <Button Click="MaximizeWindow" Grid.Column="3" Style="{StaticResource WindowChromeButton}">
                <Image Source="{StaticResource window_maximize_icon}" />
            </Button>
            <Button Click="CloseWindow" Grid.Column="4" Style="{StaticResource WindowChromeButton}">
                <Image Source="{StaticResource window_close_icon}" />
            </Button>
        </Grid>

           <!--- Main Content -->
        <Grid Grid.Row="1">
        </Grid>
    </Grid>
</Window>

这是按钮功能的示例代码：

    private void MinimizeWindow(object sender, RoutedEventArgs e) => this.WindowState = WindowState.Minimized;

    private void MaximizeWindow(object sender, RoutedEventArgs e) => this.WindowState = WindowState.Maximized;

    private void CloseWindow(object sender, RoutedEventArgs e) => this.Close();

我在做什么错了？

我最终找到了解决该问题的一种优雅解决方案。我只是为最外面的网格分配了一个名称，只要最大化它就会被检测到，并添加一个边距以确保应用程序完全覆盖屏幕并且不会移开。然后，当屏幕尺寸更改时，我将删除所述边距。

这是我的一些代码：

主要功能：

private bool isMaximized = false;

        private void CheckMaximizeChange(object sender, SizeChangedEventArgs e)
        {            
            if (WindowState == WindowState.Maximized || (isMaximized && WindowState != WindowState.Minimized)) ChangeWindow();
        }

        private void MaximizeWindow(object sender, RoutedEventArgs e) => this.WindowState ^= WindowState.Maximized;

        private void ChangeWindow()
        {
            isMaximized = !isMaximized;
            MaximizeImageButton.Source = FindResource(MaximizeImageButton.Source == FindResource("window_maximize_icon") ? "window_restore_icon" : "window_maximize_icon") as DrawingImage;
            MainGrid.Margin = new Thickness(MainGrid.Margin == new Thickness(0) ? 7 : 0);
        }

然后在应用程序的构造函数中：

SizeChanged += CheckMaximizeChange;

最大化后，我的WPF ChromeWindow稍微关闭了
