示例

此 Microsoft Visual C# .NET 示例是窗体的帮助器方法 StylusDataToString 中的代码段。此帮助器方法接受一个 Stylus 对象，并返回包含有关该手写笔及其按钮的信息的字符串。

using Microsoft.Ink;
using Microsoft.StylusInput;
using Microsoft.StylusInput.PluginData;

// ...

// Declare the RealTimeStylus objects, the GestureRecognizer plugin,
// and the DynamicRenderer plug-in.
private Microsoft.StylusInput.RealTimeStylus thePrimaryRealTimeStylus = null;
private Microsoft.StylusInput.RealTimeStylus theSecondaryRealTimeStylus = null;
private Microsoft.StylusInput.GestureRecognizer theGestureRecognizer = null;
private Microsoft.StylusInput.DynamicRenderer theDynamicRenderer = null;

// ...

// Returns information about a given stylus.
private string StylusDataToString(Stylus theStylus)
{
    System.Text.StringBuilder result = new System.Text.StringBuilder();

    // Add information about the tablet pen.
    result.Append(
        string.Format("  Name = {0}, Id = {1}, ContextId = {2}, Inverted = {3}, Button Count = {4}."
        + Environment.NewLine, theStylus.Name, theStylus.Id,
        theStylus.TabletContextId, theStylus.Inverted, theStylus.Buttons.Count));

    // Add information about each of the tabet pen's buttons.
    for (int i=0; i<theStylus.Buttons.Count; i++)
    {
        result.Append(
            string.Format("    Button {0}: Name = {1}, Id = {2}" + Environment.NewLine,
            i, theStylus.Buttons.GetName(i), theStylus.Buttons.GetId(i)));
    }

    return result.ToString();
}
