将按钮添加到窗口边框

Question

我有一个带有属性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。

Answer 1

您可能需要使用here 描述的窗口镶边库。

Answer 2

我认为这样您就可以重新创建最小化/最大化/关闭按钮。

您有两个选择，使用Grid 或DockPanel。我在下面包含了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>

具有RowDefinition Height="Auto" 的网格具有右对齐的StackPanel Orientation="Horizontal"。

但是

如果你想制作一个真正的无边框窗口，你需要做的不仅仅是将WindowStyle 设置为None。

我遇到的一个主要障碍是当WindowStyle 是None 时，它不会尊重任务栏（即重叠它），您需要连接到消息泵以设置正确的窗口约束。

如果您想知道如何执行此操作，请在 cmets 中告诉我，我们很乐意发布示例代码。

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：

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();
                        }
                    }
                }
            }
        }  
}
