[英]WindowChrome - Can't click buttons in titlebar
我的 WPF 應用程序有一個自定義的 WindowChrome 樣式(從這里摘錄: http ://www.bdevuyst.com/wpf-custom-title-bar-and-taskbar/)。
代碼在這里:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity">
<!-- Simple style without anything to remove the title bar -->
<Style x:Key="Style.Window.WindowStyleNoneWithTaskbar.Base" TargetType="{x:Type Window}">
<Setter Property="shell:WindowChrome.WindowChrome" >
<Setter.Value>
<shell:WindowChrome GlassFrameThickness="0" />
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Window}">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding Foreground}" BorderThickness="1" >
<ContentPresenter Content="{TemplateBinding Content}" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!-- Simple style with system buttons upper right -->
<Style TargetType="{x:Type Window}" BasedOn="{StaticResource Style.Window.WindowStyleNoneWithTaskbar.Base}" x:Key="Style.Window.WindowStyleNoneWithTaskbar">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Window}">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding Foreground}" BorderThickness="1">
<Grid>
<ContentPresenter
Content="{TemplateBinding Content}" />
<Canvas Grid.Column="2" HorizontalAlignment="Right" Margin="0,6,10,0" VerticalAlignment="Top" >
<Button x:Name="MinimizeButton" Style="{DynamicResource Style.Button.Core.Transparent}" Command="{Binding Source={x:Static SystemCommands.MinimizeWindowCommand}}" Width="24" Height="24" Canvas.Right="55" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Close" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.reduce}" Opacity=".5" Width="15" Height="15" />
</Button>
<Button x:Name="NormalizeButton" Style="{DynamicResource Style.Button.Core.Transparent}" Visibility="Collapsed" Command="{Binding Source={x:Static SystemCommands.RestoreWindowCommand}}" Width="24" Height="24" Canvas.Right="30" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Restore" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.normal}" Opacity=".5" Width="15" Height="15" />
</Button>
<Button x:Name="MaximizeButton" Style="{DynamicResource Style.Button.Core.Transparent}" Command="{Binding Source={x:Static SystemCommands.MaximizeWindowCommand}}" Width="24" Height="24" Canvas.Right="30" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Maximize" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.maximize}" Opacity=".5" Width="15" Height="15" />
</Button>
<Button x:Name="CloseButton" Style="{DynamicResource Style.Button.Core.Transparent}" Command="{Binding Source={x:Static SystemCommands.CloseWindowCommand}}" Width="24" Height="24" Canvas.Right="5" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Close" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.close}" Opacity=".5" Width="15" Height="15" />
</Button>
</Canvas>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="WindowState" Value="Maximized">
<Setter Property="Visibility" Value="Collapsed" TargetName="MaximizeButton" />
<Setter Property="Visibility" Value="Visible" TargetName="NormalizeButton" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
我刪除了對“shell:”的引用,因為它已被棄用,但由於某種原因,我無法單擊標題欄中的按鈕。 我從我鏈接的網站下載了示例解決方案,按鈕對我有用。
所以接下來,我添加了對“shell”的引用,但我仍然無法單擊按鈕。
我不確定我在這里做錯了什么。 我幾乎完全將示例解決方案復制到我的項目中,但它仍然不起作用。 我將每個按鈕的 IsHitTestVisibleInChrome 設置為“true”,但這並沒有什么不同。
我嘗試了其他幾種更簡單的方法,使用基本按鈕和沒有樣式,但都無濟於事。 我覺得我在這里遺漏了一些明顯的東西。
正確答案的小補充。 如果你有類似的東西:
<Button shell:WindowChrome.IsHitTestVisibleInChrome="True"
並且您的按鈕不會對點擊做出反應 - 只需移除“外殼:”
<Button WindowChrome.IsHitTestVisibleInChrome="True"
這將使他們工作
您的命令綁定是這里的問題。 不要綁定命令屬性。 只需設置它們:
<Canvas Grid.Column="2" HorizontalAlignment="Right" Margin="0,6,10,0" VerticalAlignment="Top" >
<Button x:Name="MinimizeButton" Style="{DynamicResource Style.Button.Core.Transparent}" Command="{x:Static SystemCommands.MinimizeWindowCommand}" Width="24" Height="24" Canvas.Right="55" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Close" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.reduce}" Opacity=".5" Width="15" Height="15" />
</Button>
<Button x:Name="NormalizeButton" Style="{DynamicResource Style.Button.Core.Transparent}" Visibility="Collapsed" Command="{x:Static SystemCommands.RestoreWindowCommand}" Width="24" Height="24" Canvas.Right="30" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Restore" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.normal}" Opacity=".5" Width="15" Height="15" />
</Button>
<Button x:Name="MaximizeButton" Style="{DynamicResource Style.Button.Core.Transparent}" Command="{x:Static SystemCommands.MaximizeWindowCommand}" Width="24" Height="24" Canvas.Right="30" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Maximize" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.maximize}" Opacity=".5" Width="15" Height="15" />
</Button>
<Button x:Name="CloseButton" Style="{DynamicResource Style.Button.Core.Transparent}" Command="{x:Static SystemCommands.CloseWindowCommand}" Width="24" Height="24" Canvas.Right="5" WindowChrome.IsHitTestVisibleInChrome="True" ToolTip="Close" >
<Rectangle Margin="2" Fill="{DynamicResource appbar.close}" Opacity=".5" Width="15" Height="15" />
</Button>
</Canvas>
您還需要為每個命令綁定一個命令,並按照@Louis Kottmann 在此處的建議以編程方式執行它們:
