Cursor.Inverted Property

Cursor.Inverted Property

Gets a value that indicates whether the cursor is the inverted end of the pen.

Definition

Visual Basic .NET Public ReadOnly Property Inverted As Boolean
C# public bool Inverted { get; }
Managed C++ public: __property bool* get_Inverted();

Property Value

System.Boolean. Whether the cursor is the inverted end of the pen.

This property is read-only.

trueThe cursor is the inverted end of the pen.
falseDefault. The cursor is not the inverted end of the pen, or the pen does not support a cursor associated with the inverted end of the pen.

Remarks

Inverted cursors are generally associated with erasing, so a known pen might have one end that is intended to draw ink and another end that is intended to erase strokes. However, behavior for when the system recognizes the inverted end of the pen is not limited to erasing. You may associate any acceptable cursor behavior with the Inverted property.

For more information about erasing ink, see Erasing Ink with the Pen.

Note: Whether or not you use the Inverted property is entirely up to the needs of your application. Applications are not required to inspect inverted cursors, and the ink collector applies default drawing attributes to inverted cursors just as it does to cursors that are not inverted.

Examples

[C#]

This C# example returns a report on the attributes of all of the cursors that are encountered by the InkCollector object passed in as a parameter.


using Microsoft.Ink;
//. . .
public string CursorReport(InkCollector theInkCollector)
{
    string theReport = "The InkCollector has encountered the following cursors so far:" + Environment.NewLine;
    // Get the Cursors collection from the InkCollector
    Microsoft.Ink.Cursors theCursors = theInkCollector.Cursors;
    // Prevent changes to the collection while we iterate over it.
    lock( theCursors.SyncRoot )
    {
        theReport += "Count of cursors: " + theCursors.Count + Environment.NewLine + Environment.NewLine ;
        foreach (Microsoft.Ink.Cursor cursor in theCursors)
        {
            theReport += "Cursor Name: " + cursor.Name + Environment.NewLine ;
            theReport += "Cursor ToString: " + cursor.ToString() + Environment.NewLine ;
            theReport += "Tablet Name: " + cursor.Tablet.Name  + Environment.NewLine ;
            theReport += "Cursor Id: " + cursor.Id.ToString()  + Environment.NewLine ;
            theReport += "Cursor is inverted: " + cursor.Inverted.ToString()  + Environment.NewLine ;
            theReport += "Cursor Buttons:" + Environment.NewLine;
            foreach (CursorButton button in cursor.Buttons)
            {
                CursorButtonState theState = button.State;
                theReport += "    Button Name: " + button.Name + Environment.NewLine ;
                theReport += "    State: " + button.State.ToString() + Environment.NewLine ;
                theReport += "    Id: " + button.Id.ToString()  + Environment.NewLine + Environment.NewLine;
            }
        }
    }
    return theReport;
}
