Windows 8 Store Apps学习（56）系统UI Scale, Snap,Orientation,High Contrast2014-03-09 cnblogs webabcd介绍

重新想象 Windows 8 Store Apps 之 系统 UI

获取系统的 UI 相关的设置 信息

屏幕方向

Snap

为 snap 操作和屏幕方向的改变增加动画效果

缩放至不同屏幕

高对比度

示例

1、演示如何获取系统的 UI 相关的设置 信息

UI/UISettingsInfo.xaml.cs

/* * 演示如何获取系统的 UI 相关的设置信息 */using System;using Windows.UI.ViewManagement;using Windows.UI.Xaml.Controls;using Windows.UI.Xaml.Navigation;namespace XamlDemo.UI{public sealed partial class UISettingsInfo : Page{public UISettingsInfo（）{this.InitializeComponent（）;}protected override void OnNavigatedTo（NavigationEventArgs e）{UISettings uiSettings = new UISettings（）;lblMsg.Text = "AnimationsEnabled: " + uiSettings.AnimationsEnabled; // 是否启用动画lblMsg.Text += Environment.NewLine;lblMsg.Text += "CaretBlinkRate: " + uiSettings.CaretBlinkRate; // 输入光标的闪烁速率lblMsg.Text += Environment.NewLine;/* * 光标浏览模式（Caret Browsing） - 在页面中会出现一个类似于记事本中的输入光标，用户可以使用键盘（按 Shift 键 + 方向键）来精确地进行页面文字的选择 * IE8 以上可以通过“F7”来打开/关闭光标浏览模式 */lblMsg.Text += "CaretBrowsingEnabled: " + uiSettings.CaretBrowsingEnabled; // 当前输入光标是否可用于光标浏览模式lblMsg.Text += Environment.NewLine;lblMsg.Text += "CaretWidth: " + uiSettings.CaretWidth; // 输入光标的宽度lblMsg.Text += Environment.NewLine;lblMsg.Text += "CursorSize: " + uiSettings.CursorSize; // 指针的尺寸lblMsg.Text += Environment.NewLine;lblMsg.Text += "DoubleClickTime: " + uiSettings.DoubleClickTime; // 捕获双击时，两次单击间的最长时间lblMsg.Text += Environment.NewLine;lblMsg.Text += "HandPreference: " + uiSettings.HandPreference; // 用户界面的方向（LeftHanded 或 RightHanded）lblMsg.Text += Environment.NewLine;lblMsg.Text += "MessageDuration: " + uiSettings.MessageDuration; // 消息显示的持续时间，单位：秒lblMsg.Text += Environment.NewLine;lblMsg.Text += "MouseHoverTime: " + uiSettings.MouseHoverTime; // hover 事件触发之前，指针可以 hover 的时间lblMsg.Text += Environment.NewLine;lblMsg.Text += "ScrollBarArrowSize: " + uiSettings.ScrollBarArrowSize; // 当前窗口滚动条的箭头的大小lblMsg.Text += Environment.NewLine;lblMsg.Text += "ScrollBarSize: " + uiSettings.ScrollBarSize; // 当前窗口滚动条的大小lblMsg.Text += Environment.NewLine;lblMsg.Text += "ScrollBarThumbBoxSize: " + uiSettings.ScrollBarThumbBoxSize; // 当前窗口滚动条 thumb 的大小lblMsg.Text += Environment.NewLine;// 获取当前系统的相关颜色lblMsg.Text += "ActiveCaption: " + uiSettings.UIElementColor（UIElementType.ActiveCaption）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "Background: " + uiSettings.UIElementColor（UIElementType.Background）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "ButtonFace: " + uiSettings.UIElementColor（UIElementType.ButtonFace）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "ButtonText: " + uiSettings.UIElementColor（UIElementType.ButtonText）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "CaptionText: " + uiSettings.UIElementColor（UIElementType.CaptionText）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "GrayText: " + uiSettings.UIElementColor（UIElementType.GrayText）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "Highlight: " + uiSettings.UIElementColor（UIElementType.Highlight）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "HighlightText: " + uiSettings.UIElementColor（UIElementType.HighlightText）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "Hotlight: " + uiSettings.UIElementColor（UIElementType.Hotlight）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "InactiveCaption: " + uiSettings.UIElementColor（UIElementType.InactiveCaption）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "InactiveCaptionText: " + uiSettings.UIElementColor（UIElementType.InactiveCaptionText）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "Window: " + uiSettings.UIElementColor（UIElementType.Window）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "WindowText: " + uiSettings.UIElementColor（UIElementType.WindowText）;lblMsg.Text += Environment.NewLine;AccessibilitySettings accessibilitySettings = new AccessibilitySettings（）;lblMsg.Text += "是否启用了高对比度模式: " + accessibilitySettings.HighContrast; // 是否启用了高对比度模式}}}

2、演示与“屏幕方向”相关的知识点

UI/ScreenOrientation.xaml
