RealTimeStylus.WindowInputRectangle Property

RealTimeStylus.WindowInputRectangle Property

Gets or sets the input rectangle for the RealTimeStylus object.

Definition

Visual Basic .NET Public Property WindowInputRectangle As Rectangle
C# public Rectangle WindowInputRectangle { get; set; }
Managed C++ public: __property Rectangle* get_WindowInputRectangle();
public: __property void set_WindowInputRectangle(Rectangle*);

Property Value

System.Drawing.Rectangle. The input rectangle in pixels.

This property is read/write.

(0, 0, 0, 0) Default. The input rectangle maps to the window bounds.
System.Drawing.Rectangle The input rectangle maps to the Rectangle Leave Site object.

Exceptions

COMException Leave Site:
ObjectDisposedException Leave Site: The object is already disposed.

Remarks

The input region is the intersection of the window bounds and the value of this property. When this property is set to the empty rectangle, the RealTimeStylus object will collect over the whole window, even when the window is resized.

Once the RealTimeStylus object starts collecting ink, it continues to collect ink until the stylus is raised, even if the stylus is moved outside of the input region. You can choose to handle ink that is collected outside of the input region differently in either an attached IStylusSyncPlugin object or the attached IStylusAsyncPlugin object.

This value can not be changed while the stylus is down.

Examples

This Microsoft® Visual C#® .NET example is a snippet from a form's Load Leave Site event handler, which creates a GestureRecognizer, DynamicRenderer, and two RealTimeStylus objects, attaches the objects in a cascaded RealTimeStylus model, and enables dynamic rendering, gesture recognition, and tablet pen data collection through the RealTimeStylus. The GestureRecognizer object is set to recognize single-stroke gestures and to only recognize the Right, ChevronRight, and ArrowRight application gestures. The primary RealTimeStylus object's WindowInputRectangle property is explicitly set to use the entire control to which the RealTimeStylus object is attached. The form itself implements the IStylusAsyncPlugin interface and is attached to the RealTimeStylus object.
