Gets the Cursors collection that is available for use in the inking region.

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

Syntax

'Declaration
Public ReadOnly Property Cursors As Cursors
'Usage
Dim instance As InkCollector 
Dim value As Cursors 

value = instance.Cursors

public Cursors Cursors { get; }

public:
property Cursors^ Cursors {
    Cursors^ get ();
}

public function get Cursors () : Cursors

Property Value

Type: Microsoft.Ink.Cursors
The Cursors collection that is available for use in the inking region.

Remarks

Each cursor corresponds to the tip of a pen or other ink input device.

The cursors in this collection are local to an InkCollector object.

Any new cursors that the InkCollector object encounters are added to the returned Cursors collection, although the cursors are not necessarily returned in the order in which the InkCollector object encounters them.

When you enable a mouse as an input device on the InkCollector object (when the useMouseForInput parameter of the SetAllTabletsMode method is true), the mouse is added to the Cursors collection after the InkCollector encounters any other cursor, such as a pen. This is because the pen also acts like a mouse.

Note

The CursorInRange event is received for the mouse cursor after any other cursor, such as when a pen draws a stroke (which fires the Stroke event).

The Cursors collection is cleared (count set to 0, containing no objects) when:

The tablet mode is changed (for example, from SetSingleTabletIntegratedMode to SetAllTabletsMode).
The SetSingleTabletIntegratedMode method is called.

Examples

This C# example returns a report on the attributes of all of the cursors seen 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;
}
