如何使用C＃查看** winrt **应用程序中的特定设置页面？

Question

如何使用C＃从外部按钮点击查看 winrt 应用程序中的特定设置页面？

在javascript中，我发现像 WinJS.UI.SettingsFlyout.showSettings（“关于”，“/设置/关闭”）

但是我无法在c＃中找到这个，我使用 callisto 来设置弹出窗口

Answer 1

我也在使用Callisto和C＃，这就是我解决问题的方法。

    void OnCommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
    {
        var settings = new SettingsCommand("settings", "Settings", new UICommandInvokedHandler(showSettings));
        args.Request.ApplicationCommands.Add(settings);
        var credits = new SettingsCommand("credits", "Credits", new UICommandInvokedHandler(showCredits));
        args.Request.ApplicationCommands.Add(credits);
    }

    public void showSettings(IUICommand command)
    {
        var settings = new SettingsFlyout();
        settings.Content = new SettingsUserControl();
        settings.HeaderBrush = new SolidColorBrush(_background);
        settings.Background = new SolidColorBrush(_background);
        settings.HeaderText = "Settings";
        settings.IsOpen = true;
    }

    public void showCredits(IUICommand command)
    {
        var settings = new SettingsFlyout();
        settings.Content = new CreditsUserControl();
        settings.HeaderBrush = new SolidColorBrush(_background);
        settings.Background = new SolidColorBrush(_background);
        settings.HeaderText = "Credits";
        settings.IsOpen = true;
    }

然后从其他页面我可以致电

((App)Application.Current).showCredits(null);  

或

((App)Application.Current).showSettings(null);

打开我想看的设置窗格：o）

第一步是在SettingsPane上为要显示设置的页面添加CommandsRequest事件的侦听器。例如：

SettingsPane.GetForCurrentView().CommandsRequested += MainPage_CommandsRequested;

然后定义事件处理程序

void MainPage_CommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
{
    SettingsCommand generalCommand = new SettingsCommand("GeneralSettings", ResourceLoader.GetString("GeneralText"), (x) =>
    {
        SettingsFlyout settings = new SettingsFlyout();
        settings.HeaderBrush = Resources["SettingsHeaderBrush"] as SolidColorBrush;
        settings.HeaderText = ResourceLoader.GetString("GeneralText");
        settings.Background = new SolidColorBrush(Windows.UI.Colors.White);
        settings.Content = new GeneralSettingsFlyout();
        settings.IsOpen = true;
        settings.Height = Window.Current.Bounds.Height;

        // Optionally, add a closed event handler
        settings.Closed += settings_Closed;
    });
}

请注意，在这种情况下，GeneralSettingsFlyout只是一个页面，一旦选择了特定的设置，它就会被加载到设置窗格中（Callisto会自动处理）。

SettingsFlyout是来自Callisto的类。

修改您的app.xaml文件，并参考以下代码段：

App::OnLaunched()
{
.
.
     var rootFrame = new CharmFrame { CharmContent = new CharmFlyouts() };
     SuspensionManager.RegisterFrame(rootFrame, "AppFrame");
.
.
}

然后，当您想要显示该设置时，请执行以下操作：

SomeOtherMethod()
{
     ((Window.Current.Content as CharmFrame).CharmContent as CharmFlyouts).ShowSettings();
}
