在WPF中,我可以拥有一个无边框窗口,它具有常规的最小化,最大化和关闭按钮吗？

Question

如果您在最大化时查看Chrome浏览器,则其标签页眉位于窗口顶部.我可以做类似的事吗？

Answer 1

当然,但你必须自己重拍这些按钮(这并不难,不用担心).

在您的MainWindow.xaml中:

<Window ...
        Title="" Height="Auto" Width="Auto" Icon="../Resources/MyIcon.ico" 
        ResizeMode="NoResize" WindowStartupLocation="CenterScreen" 
        WindowStyle="None" AllowsTransparency="True" Background="Transparent"
        ...>
    <Canvas>
       <Button /> <!-- Close -->
       <Button /> <!-- Minimize -->
       <Button /> <!-- Maximize -->
       <TabControl>
           ...
       </TabControl>
    </Canvas>
</Window>

然后你只需将Buttons和TabControl放在Canvas上,并自定义外观.

编辑:在.NET 4.5中关闭/最大化/最小化的内置命令是SystemCommands.CloseWindowCommand/ SystemCommands.MaximizeWindowCommand/SystemCommands.MinimizeWindowCommand

因此,如果您使用的是.NET 4.5,则可以执行以下操作:

<Window ...
        Title="" Height="Auto" Width="Auto" Icon="../Resources/MyIcon.ico" 
        ResizeMode="NoResize" WindowStartupLocation="CenterScreen" 
        WindowStyle="None" AllowsTransparency="True" Background="Transparent"
        ...>
    <Window.CommandBindings>
        <CommandBinding Command="{x:Static SystemCommands.CloseWindowCommand}" CanExecute="CommandBinding_CanExecute_1" Executed="CommandBinding_Executed_1" />
        <CommandBinding Command="{x:Static SystemCommands.MaximizeWindowCommand}" CanExecute="CommandBinding_CanExecute_1" Executed="CommandBinding_Executed_2" />
        <CommandBinding Command="{x:Static SystemCommands.MinimizeWindowCommand}" CanExecute="CommandBinding_CanExecute_1" Executed="CommandBinding_Executed_3" />
    </Window.CommandBindings>
    <Canvas>
       <Button Command="{x:Static SystemCommands.CloseWindowCommand}" Content="Close" />
       <Button Command="{x:Static SystemCommands.MaximizeWindowCommand}" Content="Maximize" />
       <Button Command="{x:Static SystemCommands.MinimizeWindowCommand}" Content="Minimize" />
       <TabControl>
           ...
       </TabControl>
    </Canvas>
</Window>

在你的C#代码隐藏中:

    private void CommandBinding_CanExecute_1(object sender, CanExecuteRoutedEventArgs e)
    {
        e.CanExecute = true;
    }

    private void CommandBinding_Executed_1(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.CloseWindow(this);
    }

    private void CommandBinding_Executed_2(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.MaximizeWindow(this);
    }

    private void CommandBinding_Executed_3(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.MinimizeWindow(this);
    }

这将使得关闭/最大化/最小化工作与常规窗口完全相同.
当然,您可能希望使用System.Windows.Interactivity将C#移动到ViewModel中.
