C＃检测口音颜色变化的WinRT XAML [英] C# Detect Accent Colour Changes WinRT XAML

问题描述

我试图来检测Application.Resources资源词典的变化，这样我就可以在标题栏自动改变为雅绅特色时更新。所有XAML控件和元素的自动变化，和纯色画笔设置为 DSDFS 的刷子，其内在价值的变化。

I am trying to detect changes in the Application.Resources Resource dictionary, so I can automatically change the Titlebar to the Accent Colour when it updates. All of the XAML controls and elements change automatically, and when setting a solid colour brush to the address of the DSDFS brush, its internal value changes.

这是我曾尝试使用来检测变化的代码：

This is the code I have tried to use to detect the change:

public static DependencyProperty accent = DependencyProperty.Register("DictChange", typeof(ResourceDictionary), typeof(Shell), new PropertyMetadata(Application.Current.Resources, new PropertyChangedCallback(accent_PropertyChanged)));

public ResourceDictionary DictChange
{
    get { return (ResourceDictionary)GetValue(accent); }
    set { SetValue(accent, value); }
}

private static void accent_PropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
    _app.SetTitlebar();
}

我虽然承担了错，还是我不知道如果这就是做检测更改正确的事情。有一个前一次迭代中，我用 Application.Current.Resources [SystemControlBackgroundAccentBrush]作为的SolidColorBrush 并试图发现其财产，但没有任何工作。

I'm assuming its wrong though, or I'm not sure if that is the right thing to do to detect changes. There was a previous iteration where I used Application.Current.Resources["SystemControlBackgroundAccentBrush"] as SolidColorBrush and tried to detect its property, but that didn't work either.

我在做什么错了？请帮助：）

What am I doing wrong? Please help :)

推荐答案

这也许不能算错，但它可能无法提供最佳的解决方案。

It might not be wrong, but it's probably not the best solution available.

在WinRT的XAML，我们有这个新的 ThemeResource 自动更新的资源。棘手位是找到绑定 ApplicationView.GetForCurrentView（）的方法。TitleBar.BackgroundColor 到 SystemControlBackgroundAccentBrush 。

In WinRT XAML, we have this new ThemeResource that updates the resources automatically. The tricky bit is to find a way to bind the ApplicationView.GetForCurrentView().TitleBar.BackgroundColor to SystemControlBackgroundAccentBrush.

在我回答这个问题，我创建了一个行为是一个附加的自定义的 TitleBar中页面。如果修改背景属性来这样的事情 -

In my answer to this question, I created a Behavior that attaches a custom TitleBar to the page. If you modify the Background property to something like this -

<local:FullScreenModeTitleBarBehavior Background="{ThemeResource SystemControlBackgroundAccentBrush}" />

现在运行的应用，你会看到当您更改强调色背景色被更新，如下面的图片 -

Now run the app and you will see the background color gets updated when you change the accent color of the system, as shown in the picture below -

基本上你的情况，你只需要创建一个类似（安培;简单）行为，像一座桥的行为联系起来的 BackgroundColor中的标题栏到 SystemControlBackgroundAccentBrush ，通过 ThemeResource 绑定。

Basically in your case, you just need to create a similar (& simpler?) Behavior that acts like a bridge to link the BackgroundColor of the TitleBar to the SystemControlBackgroundAccentBrush, via ThemeResource binding.
