Gets the maximum input rectangle, in tablet device coordinates, that the Tablet object supports.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public ReadOnly Property MaximumInputRectangle As Rectangle
'Usage
Dim instance As Tablet 
Dim value As Rectangle 

value = instance.MaximumInputRectangle

public Rectangle MaximumInputRectangle { get; }

public:
property Rectangle MaximumInputRectangle {
    Rectangle get ();
}

public function get MaximumInputRectangle () : Rectangle

Property Value

Type: System.Drawing.Rectangle
The maximum input rectangle, in tablet device coordinates, that the Tablet supports.

Remarks

The rectangle returned by the MaximumInputRectangle property specifies the maximum allowable space in which ink can be drawn.

Note

This function can be re-entered if called within certain message handlers, causing unexpected results. Take care to avoid a reentrant call when handling any of the following messages: WM_ACTIVATE, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_PAINT; WM_SYSCOMMAND if wParam is set to SC_HOTKEY or SC_TASKLIST; and WM_SYSKEYDOWN (when processing Alt-Tab or Alt-Esc key combinations). This is an issue with single-threaded apartment model applications.

Examples

This example reports on the Plug and Play ID, the hardware capabilities and the maximum input rectangle of the default Tablet object in the Tablets collection.

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();
}
