InputPanel.InputMethodCollection 类

项目
08/18/2008

提供对 Pocket PC 上安装的所有输入法软件的访问权。无法继承此类。

命名空间： Microsoft.WindowsCE.Forms
程序集： Microsoft.WindowsCE.Forms（在 Microsoft.WindowsCE.Forms.dll 中）

语法

声明
Public NotInheritable Class InputMethodCollection _
    Implements IList, ICollection, IEnumerable
用法
Dim instance As InputPanel.InputMethodCollection

public sealed class InputMethodCollection : IList, 
    ICollection, IEnumerable

public ref class InputMethodCollection sealed : IList, 
    ICollection, IEnumerable

public final class InputMethodCollection implements IList, ICollection, IEnumerable

备注

此集合访问 Pocket PC 上的软输入面板 (SIP) 中的文本和字符条目的方法。常用输入法包括：

键盘

点击 SIP 键盘或硬件键盘附件上的字符。
字母识别器

在 SIP 上绘制字母和数字。当用户暂停时，笔迹将自动转换为键入的文本，并显示在插入点。
块识别器

在 SIP 上绘制预设的、显示为特定字符的笔划。此输入法类似于 graffiti 枚举。

可以安装其他输入法以支持日语和俄语之类的语言。在设备上安装了新的输入法后，它将被加入到输入法集合中。

使用 InputMethods 属性来获取一个 InputPanel.InputMethodCollection。

示例

下面的代码示例枚举 InputPanel.InputMethodCollection 并在列表框中列出可用的输入法。当用户选择输入法时，CurrentInputMethod 属性被设置为该输入法。输入面板的 Enabled 属性设置为 true，从而为用户显示键盘和其他输入区域。
