Tablet.MaximumInputRectangle 属性

获取 Tablet 对象所支持的最大输入矩形(采用 Tablet 设备坐标)。

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

语法

声明
Public ReadOnly Property MaximumInputRectangle As Rectangle
用法
Dim instance As Tablet
Dim value As Rectangle

value = instance.MaximumInputRectangle
public Rectangle MaximumInputRectangle { get; }
public:
property Rectangle MaximumInputRectangle {
    Rectangle get ();
}
/** @property */
public Rectangle get_MaximumInputRectangle()
public function get MaximumInputRectangle () : Rectangle

属性值

类型:System.Drawing.Rectangle
Tablet 所支持的最大输入矩形(采用 Tablet 设备坐标)。

备注

MaximumInputRectangle 属性返回的矩形负责指定可以绘制墨迹 的最大空间范围。

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_ACTIVATEWM_ACTIVATEAPPWM_NCACTIVATEWM_PAINTWM_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();
}
