예제

다음 예제에서는 사용 하는 방법에 설명 합니다 GetCharFromPosition 의 내용에서 문자를 가져오는 방법을 RichTextBox 컨트롤 좌표가 지정 된 합니다.The following example demonstrates how to use the GetCharFromPosition method to obtain a character from the contents of a RichTextBox given its control coordinates. 에 있는 좌표를 사용 하는 예제 코드는 MouseEventArgs 개체 문자를 가져올 컨트롤의 위치를 확인 하려면 이벤트 처리기에 매개 변수로 전달 합니다.The example code uses coordinates located in the MouseEventArgs object passed as a parameter to the event handler to determine the location in the control to obtain the character. 문자 다음에 표시 되는 MessageBox 공백 문자가 없는 경우.The character is then displayed in a MessageBox if it is not a space character. 이 가정를 RichTextBox 라는 컨트롤 richTextBox1 만들었습니다 및 예제 코드에 연결 된를 MouseDown 의 이벤트는 RichTextBox합니다.This example assumes that a RichTextBox control named richTextBox1 has been created and that the example code is connected to the MouseDown event of the RichTextBox.

private:
   void richTextBox1_MouseDown( Object^ /*sender*/, System::Windows::Forms::MouseEventArgs^ e )
   {
      // Determine which mouse button is clicked.
      if ( e->Button == ::MouseButtons::Left )
      {
         // Obtain the character at which the mouse cursor was clicked at.
         Char tempChar = richTextBox1->GetCharFromPosition( Point(e->X,e->Y) );

         // Determine whether the character is an empty space.
         if (  !tempChar.ToString()->Equals( " " ) )

         // Display the character in a message box.
         MessageBox::Show( String::Format( "The character at the specified position is {0}.", tempChar ) );
      }
   }
private void richTextBox1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
	// Determine which mouse button is clicked.
	if(e.Button == MouseButtons.Left)
	{
		// Obtain the character at which the mouse cursor was clicked at.
		char tempChar = richTextBox1.GetCharFromPosition(new Point(e.X, e.Y));
		// Determine whether the character is an empty space.
		if (tempChar.ToString() != " ")
			// Display the character in a message box.
			MessageBox.Show("The character at the specified position is " + tempChar + ".");

	}
}
Private Sub richTextBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles richTextBox1.MouseDown
    ' Determine which mouse button is clicked.

다음 예제에서는 여러 마우스 이벤트를 사용 하 여 마우스의 경로에 그릴는 Panel합니다.The following example demonstrates using different mouse events to draw the path of the mouse on a Panel. 선 세그먼트에 추가 되는 GraphicsPath 각각에 대해 MouseMoveMouseDown 발생 하는 이벤트입니다.A line segment is added to the GraphicsPath for each MouseMove and MouseDown events that occur. 그래픽을 업데이트 하는 Invalidate 메서드를 호출 합니다 PanelMouseDownMouseUp 이벤트입니다.To update the graphics, the Invalidate method is called for the Panel on each MouseDown and MouseUp event. 그래픽 경로 위나 아래로 때 스크롤되는 또한는 MouseWheel 이벤트가 발생 합니다.In addition, the graphic path is scrolled up or down when the MouseWheel event occurs. 와 같은 추가 마우스 이벤트가 MouseHover, 화면에서 식별 됩니다.Additional mouse events, like MouseHover, are identified on screen as well. 마우스에 대 한 추가 정보는 화면에 표시 된 SystemInformation 클래스입니다.Also displayed on the screen is additional information about the mouse from the SystemInformation class.
