我有一个属性为WindowStyle="SingleBorderWindow"的WPF窗口。
现在我想知道如何在窗口边框的左上角设置一个按钮。

您可能需要使用描述为here的窗口铬库。

我认为这样你可以重新创建最小化/最大化/关闭按钮。
您有两种选择，使用Grid或DockPanel。我在下面列出了Grid的示例。
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<Grid.RowDefinitions>
<StackPanel Orientation="Horizontal" Margin="2,0" HorizontalAlignment="Right" VerticalAlignment="Top">
</StackPanel>
</Grid>
RowDefinition Height="Auto"的网格，其StackPanel Orientation="Horizontal"右对齐。
<强>然而
如果您想制作一个真正的无边框窗口，除了将WindowStyle设置为None之外，您还需要做更多工作。
我遇到的一个主要障碍是当WindowStyle为None时，它不会尊重任务栏（即重叠它），你需要挂钩到消息泵来设置正确的窗口约束。
如果你想知道如何做到这一点，请在评论中告诉我，会很高兴发布示例代码。

您需要通过设置透明度，背景和样式来制作自定义窗口，如下所示：
<Window x:Class="WpfApplication2.Window2"
Name="Window2xx"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
Title="window1"
xmlns:m="clr-namespace:WpfApplication2"
AllowsTransparency="True" WindowStyle="None"
WindowStartupLocation="CenterOwner" d:DesignWidth="410" StateChanged="Window_StateChanged"
SizeToContent="WidthAndHeight" ShowInTaskbar="False" Background="Transparent">
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Style.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
<Grid>
<m:MasterWindow Width="400">
<m:MasterWindow.WindowTitle>
<ContentPresenter Content="window1" MouseLeftButtonDown="Window_MouseLeftButtonDown"></ContentPresenter>
</m:MasterWindow.WindowTitle>
<m:MasterWindow.Content>
<Grid>
</Grid>
</m:MasterWindow.Content>
</m:MasterWindow>
</Grid>
</Window>
window2后面的代码：
namespace WpfApplication2
{
public partial class Window2 : Window
{
public Window2()
{
InitializeComponent();
}
private void Window_StateChanged(object sender, EventArgs e)
{
if (((Window)sender).WindowState == WindowState.Maximized)
((Window)sender).WindowState = WindowState.Normal;
}
private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
try
{
DragMove();
}
catch ()
{}
}
}
}
主窗口如下所示：
namespace WpfApplication2
{
public class MasterWindow : ContentControl
{
public static RoutedCommand CloseWindowCommand;
static MasterWindow()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(MasterWindow), new FrameworkPropertyMetadata(typeof(MasterWindow)));
CloseWindowCommand = new RoutedCommand("CloseWindow", typeof(MasterWindow));
CommandManager.RegisterClassCommandBinding(typeof(MasterWindow), new CommandBinding(CloseWindowCommand, CloseWindowEvent));
}
public static readonly DependencyProperty WindowTitleProperty = DependencyProperty.Register("WindowTitle", typeof(object), typeof(MasterWindow), new UIPropertyMetadata());
public object WindowTitle
{
get { return (object)GetValue(WindowTitleProperty); }
set { SetValue(WindowTitleProperty, value); }
}
private static void CloseWindowEvent(object sender, ExecutedRoutedEventArgs e)
{
MasterWindow control = sender as MasterWindow;
if (control != null)
{
Window objWindow = Window.GetWindow(((FrameworkElement)sender));
if (objWindow != null)
{
if (objWindow.Name.ToLower() != "unlockscreenwindow")
{
Window.GetWindow(((FrameworkElement)sender)).Close();
}
}
}
}
}
}
主窗口的样式：
