InkEdit에서 애플리케이션 사전 사용

애플리케이션 사전을 만들려면 RecognizerContext 개체의 WordList 속성을 설정해야 합니다. InkEdit 컨트롤은 RecognizerContext 개체를 노출하지 않으므로 InkEdit 컨트롤의 RecognizerContext 개체의 WordList 속성을 직접 설정할 수 없습니다.

InkEdit 컨트롤과 함께 애플리케이션 사전을 사용하려면 InkEdit 컨트롤에서 스트로크를 가져와서 WordList 속성이 애플리케이션 사전이 포함된 WordList로 설정된 새 RecognizerContext 개체에 전달하고, 이 RecognizerContext 개체의 결과를 저장한 다음, 결과를 InkEdit 컨트롤에 다시 전달해야 합니다.

예제

다음 C# 코드는 이 기술의 예를 보여줍니다.

private RecognizerContext rc;
private WordList wl;
private int wlSelStart;
private int wlSelLen;
private bool isRecoPending = false;

private void Form1_Load(object sender, EventArgs e)
{
  //event handlers must be attached for dictionary to work.
  inkEdit1.Recognition += new Microsoft.Ink.InkEditRecognitionEventHandler(inkEdit1_Recognition);
  inkEdit1.TextChanged += new EventHandler(inkEdit1_TextChanged);

  //create a WordList that contains the application dictionary
  wl = new WordList();
  //...
  //Add dictionary terms to the WordList
  //...

  // create a RecognizerContext for the WordList
  rc = inkEdit1.Recognizer.CreateRecognizerContext();
  rc.Factoid = Factoid.WordList;

  //set the RecognizerContext WordList to the newly created WordList
  rc.WordList = wl;

  //create a delegate for the new RecognizerContext
  rc.RecognitionWithAlternates += new

  RecognizerContextRecognitionWithAlternatesEventHandler(rc_Recognition);
}

void inkEdit1_TextChanged(object sender, EventArgs e)
{
  if (isRecoPending)
  {
    isRecoPending = false;
    rc.BackgroundRecognizeWithAlternates();
  }
}

private void inkEdit1_Recognition(object sender,
Microsoft.Ink.InkEditRecognitionEventArgs e)
{
  //store the start of the selection in wlSelStart
  wlSelStart = inkEdit1.SelectionStart;

  //store the length of the selection in wlSelLen
  wlSelLen = e.RecognitionResult.TopString.Length;

  //copy the strokes from the InkEdit control into the new
  // RecognizerContext
  rc.Strokes = e.RecognitionResult.Strokes.Ink.Clone().Strokes;
  isRecoPending = true;
}

private void rc_Recognition(object sender,
Microsoft.Ink.RecognizerContextRecognitionWithAlternatesEventArgs e)
{
  if (inkEdit1.InvokeRequired)
  {
    inkEdit1.Invoke(new RecognizerContextRecognitionWithAlternatesEventHandler(rc_Recognition),
      new object[] { sender, e });
    return;
  }

  //set the insertion point in the InkEdit control
  inkEdit1.SelectionStart = wlSelStart;
  inkEdit1.SelectionLength = wlSelLen;
  //insert the result from the new RecognizerContext 
  //into the InkEdit control
  inkEdit1.SelectedText = e.Result.TopString;
  inkEdit1.SelectionStart = inkEdit1.SelectionStart +
  e.Result.TopString.Length;
}

// Event handler for the form's closed event
private void Form1_Closed(object sender, System.EventArgs e)
{
  inkEdit1.Dispose();
  inkEdit1 = null;
  rc.Dispose();
  rc = null;
}
