Tablet.HardwareCapabilities 属性

从定义 Tablet 对象的硬件功能的 TabletHardwareCapabilities 枚举获取一个值。

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

语法

声明
Public ReadOnly Property HardwareCapabilities As TabletHardwareCapabilities
用法
Dim instance As Tablet
Dim value As TabletHardwareCapabilities

value = instance.HardwareCapabilities

public TabletHardwareCapabilities HardwareCapabilities { get; }

public:
property TabletHardwareCapabilities HardwareCapabilities {
    TabletHardwareCapabilities get ();
}

/** @property */
public TabletHardwareCapabilities get_HardwareCapabilities()

public function get HardwareCapabilities () : TabletHardwareCapabilities

属性值

类型：Microsoft.Ink.TabletHardwareCapabilities
Tablet 对象的硬件功能。

备注

Tablet 对象的硬件功能包括光标是否必须与 Tablet 实际接触才报告其位置，以及数字化仪 是否与显示屏集成。使用按位比较确定某个特定 Tablet 对象对应有哪些硬件功能。有关硬件功能值的完整列表，请参见 TabletHardwareCapabilities 枚举类型。

备注

如果在某些消息处理程序内调用此函数，则可以重新进入此函数，从而导致意外的结果。在处理以下任一消息时，请注意避免可重入调用：WM_ACTIVATE、WM_ACTIVATEAPP、WM_NCACTIVATE、WM_PAINT；WM_SYSCOMMAND（如果 wParam 设置为 SC_HOTKEY 或 SC_TASKLIST）；以及 WM_SYSKEYDOWN（处理 Alt-Tab 或 Alt-Esc 组合键时）。这是单线程单元模型应用程序的问题。

示例

此示例报告 Tablets 集合中的默认 Tablet 对象的即插即用 ID、硬件功能以及最大输入矩形。

Public Function Report_Hardware_DefaultTablet() As String
    Dim SB As StringBuilder = New StringBuilder(1024)
    Dim defTablet As Tablet = New Tablets().DefaultTablet

    ' report on the hardware capabilities of the default tablet
    SB.AppendLine("Hardware capabilities of the default tablet: " + defTablet.Name)
    SB.AppendLine("PlugAndPlayId: " + defTablet.PlugAndPlayId)

    If (defTablet.HardwareCapabilities And TabletHardwareCapabilities.CursorMustTouch) <> 0 Then
        SB.AppendLine("CursorMustTouch: YES")
    Else
        SB.AppendLine("CursorMustTouch: NO")
    End If

    If (defTablet.HardwareCapabilities And TabletHardwareCapabilities.CursorsHavePhysicalIds) <> 0 Then
        SB.AppendLine("CursorsHavePhysicalIds: YES")
    Else
        SB.AppendLine("CursorsHavePhysicalIds: NO")
    End If

    If (defTablet.HardwareCapabilities And TabletHardwareCapabilities.HardProximity) <> 0 Then
        SB.AppendLine("HardProximity:: YES")
    Else
        SB.AppendLine("HardProximity:: NO")
    End If

    If (defTablet.HardwareCapabilities And TabletHardwareCapabilities.Integrated) <> 0 Then
        SB.AppendLine("Integrated: YES")
    Else
        SB.AppendLine("Integrated: NO")
    End If

    SB.AppendLine("MaximumInputRectangle " + defTablet.MaximumInputRectangle.ToString())

    Return SB.ToString()
End Function

public string Report_Hardware_DefaultTablet()
{
    StringBuilder SB = new StringBuilder(1024);
    Tablet defTablet = new Tablets().DefaultTablet;

    // report on the hardware capabilities of the default tablet
    SB.AppendLine("Hardware capabilities of the default tablet: " + defTablet.Name);
    SB.AppendLine("PlugAndPlayId: " + defTablet.PlugAndPlayId);

    SB.AppendLine("CursorMustTouch: " +
        (((defTablet.HardwareCapabilities & TabletHardwareCapabilities.CursorMustTouch) != 0) ? "YES" : "NO"));

    SB.AppendLine("CursorsHavePhysicalIds: " +
        (((defTablet.HardwareCapabilities & TabletHardwareCapabilities.CursorsHavePhysicalIds) != 0) ? "YES" : "NO"));

    SB.AppendLine("HardProximity: " +
        (((defTablet.HardwareCapabilities & TabletHardwareCapabilities.HardProximity) != 0) ? "YES" : "NO"));

    SB.AppendLine("Integrated: " +
        (((defTablet.HardwareCapabilities & TabletHardwareCapabilities.Integrated) != 0) ? "YES" : "NO"));

    SB.AppendLine("MaximumInputRectangle " + defTablet.MaximumInputRectangle.ToString());

    return SB.ToString();
}
