設置WPF復選框的不確定狀態

Question

我想設置WPF復選框的不確定狀態。 我們有一個帶有復選框的樹視圖控件，我們希望不確定狀態表示某些后代被檢查而一些未被選中。

我到處看到的解決方案是覆蓋復選框的默認控件模板並執行我需要做的事情。

我有兩個問題：

1. 我找不到普通Aero復選框的控件模板。 這個： http ： //msdn.microsoft.com/en-us/library/ms752319.aspx看起來很傻。

2. 我從Expression Blend獲得的控件模板中包含了BulletChrome元素，我無法弄清楚該怎么做。

那么有誰知道在哪里獲得看起來“正常”的復選框控制模板，或者是否有更簡單的方法來自行設置不確定狀態？

我確信有一種簡單的方法我只是忽略......對嗎？

Answer 2

您是否已經嘗試下載Aero Theme xaml並進行了調查？
我在哪里可以下載Microsoft的標准WPF主題？

Answer 3

叫我瘋了，但我實際上在純XAML中重新實現了標准的Aero復選框。 如果您想自定義Aero復選框，這是一個很好的起點。 您可以在我的存儲庫中找到GitHub上的其他樣式（ 特定提交 ，以防文件被移動）。

筆記：

1. {xx:SystemBrush ControlText}是{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}的快捷方式。 您可以使用該快捷方式，也可以只使用正則表達式查找和替換。

2. 不支持RTL，動畫，奇怪的情況。

3. 這種風格比使用BulletChrome大量優化的BulletChrome慢。

Answer 4

您可以使用位於以下位置的經典主題的CheckBox樣式：

• C:\\Program Files (x86)\\Microsoft Expression\\Blend 4\\SystemThemes\\Wpf\\classic.xaml

這實現了一個Path表示名為復選框標記CheckMarkPath 。 我只是用填充的Rectangle替換了這個Path來獲得這些結果：

Answer 5

您可以將復選框的IsThreeState屬性設置為true。

但是，這允許將復選框的值切換為null。
如果這是不受歡迎的，你可以在CheckBox的模板中添加null值的觸發器，就像Greg Bacchus 在他的回答中所示 ：

<ControlTemplate.Triggers>
    <Trigger Property="IsChecked" Value="{x:Null}">
        <!-- TODO: Do Stuff Here -->
    </Trigger>
</ControlTemplate.Triggers>

修改控件現有外觀的最佳軟件是Expression Blend。 如果要更改現有外觀，則必須修改控件的“控件模板”。

Answer 7

另一個選項可能是設置切換按鈕的樣式，因為它也有多個狀態。 在過去的項目中，我創建了自定義切換按鈕，其中包含多個狀態，這些狀態看起來像chekcbox一樣。 我確實使用了混合來進行更改但是使用切換按鈕作為基礎我能夠為按鈕/ chekcbox的各種狀態創建更加自定義的外觀。 使用切換按鈕可以繞過許多與標准chekcbox控件緊密相關的chrome相關問題。

Answer 8

您是否考慮過使用SimpleStyles作為控制基礎？

通過從Assets面板中選擇此控件，Expression Blend將在您的項目中放置一個新的資源dictonary，您可以使用它來修改樣式。 可能是一個更好的起點，而不是試圖入侵Chrome標准復選框。

Answer 9

使用Blend中的模板：

要使BulletChrome工作，您需要添加對PresentationFramework.Aero的引用 ，並為“theme”命名空間添加xml命名空間聲明：

xmlns:theme="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"

我自己沒有嘗試過，但我相信它應該可行（我已經用Luna完成了）。
