Property Value

Type: System.Int32
The number of buttons on the stylus.

Remarks

The list of buttons provided in this collection indicate what is supported by a digitizer and not necessarily what is present on the pen. You can determine the state of a specific stylus button, and confirm its presence, when the plug-in receives the StylusButtonDown and StylusButtonUp notifications.

Examples

This Microsoft Visual C# .NET example shows an event handler for the StylusInRange method implemented on a form:

public class Form1 : Form, IStylusAsyncPlugin
{
    private RealTimeStylus rts;
    private DynamicRenderer dr;
    private System.Windows.Forms.TextBox textBox1;
    public Form1()
    {
        rts = new RealTimeStylus(this);
        dr = new DynamicRenderer(this);
        rts.SyncPluginCollection.Add(dr);
        rts.AsyncPluginCollection.Add(this);
        rts.Enabled = true;
        dr.Enabled = true;

        InitializeComponent();
    }
    // ...
    public Microsoft.StylusInput.DataInterestMask DataInterest
    {
        get{return DataInterestMask.AllStylusData;}
    }
    public void StylusInRange(RealTimeStylus sender, StylusInRangeData data)
    {
        string sInverted = data.Stylus.Inverted ? "is inverted" : "is not inverted";
        
        textBox1.AppendText(
            string.Format("{0} in range; {1}; has {2} buttons:{3}", 
                data.Stylus.Name, 
                sInverted,
                data.Stylus.Buttons.Count,
                Environment.NewLine)
            );

        for (int i=0; i<data.Stylus.Buttons.Count; i++)
        {
            textBox1.AppendText(
                string.Format("    {0}: {1}{2}", 
                    i.ToString(),
                    data.Stylus.Buttons.GetName(i),
                    Environment.NewLine)
                );
        }
    }
    // ...
