특성

예제

다음 코드 예제에서는 둥근 단추를 만들어 Region 속성을 사용 하는 방법을 보여 줍니다.The following code example demonstrates how to use the Region property by creating a round button. 예제를 실행 하려면 roundButton 이라는 단추가 포함 된 폼에 다음 코드를 붙여넣습니다.To run the example, paste the following code in a form containing a button called roundButton. 이 예에서는 Paint 이벤트가 예제에 정의 된 이벤트 처리기에 연결 되어야 합니다.This example requires that the Paint event is connected to the event handler defined in the example.

private:
   // This method will change the square button to a circular button by 
   // creating a new circle-shaped GraphicsPath object and setting it 
   // to the RoundButton objects region.
   void roundButton_Paint( Object^ sender,
      System::Windows::Forms::PaintEventArgs^ e )
   {
      System::Drawing::Drawing2D::GraphicsPath^ buttonPath =
         gcnew System::Drawing::Drawing2D::GraphicsPath;
      
      // Set a new rectangle to the same size as the button's 
      // ClientRectangle property.
      System::Drawing::Rectangle newRectangle = roundButton->ClientRectangle;
      
      // Decrease the size of the rectangle.
      newRectangle.Inflate(  -10, -10 );
      
      // Draw the button's border.
      e->Graphics->DrawEllipse( System::Drawing::Pens::Black, newRectangle );
      
      // Increase the size of the rectangle to include the border.
      newRectangle.Inflate( 1, 1 );
      
      // Create a circle within the new rectangle.
      buttonPath->AddEllipse( newRectangle );
      
      // Set the button's Region property to the newly created 
      // circle region.
      roundButton->Region = gcnew System::Drawing::Region( buttonPath );
   }
// This method will change the square button to a circular button by 
// creating a new circle-shaped GraphicsPath object and setting it 
// to the RoundButton objects region.

    System.Windows.Forms.PaintEventArgs e)
{

    System.Drawing.Drawing2D.GraphicsPath buttonPath =

    // Set a new rectangle to the same size as the button's 
    // ClientRectangle property.
    System.Drawing.Rectangle newRectangle = roundButton.ClientRectangle;

    // Decrease the size of the rectangle.
    newRectangle.Inflate(-10, -10);
    
    // Draw the button's border.
    e.Graphics.DrawEllipse(System.Drawing.Pens.Black, newRectangle);

    // Increase the size of the rectangle to include the border.
    newRectangle.Inflate( 1,  1);

    buttonPath.AddEllipse(newRectangle);
            
    // Set the button's Region property to the newly created 
    // circle region.
    roundButton.Region = new System.Drawing.Region(buttonPath);

설명

창 영역은 운영 체제에서 그리기를 허용 하는 창 내의 픽셀 컬렉션입니다.The window region is a collection of pixels within the window where the operating system permits drawing. 운영 체제 창의 창 영역 외부에 있는 일부가 표시 되지 않습니다.The operating system does not display any portion of a window that lies outside of the window region. 컨트롤 영역의 좌표는 컨트롤의 클라이언트 영역이 아니라 컨트롤의 왼쪽 위 모퉁이를 기준으로 합니다.The coordinates of a control's region are relative to the upper-left corner of the control, not the client area of the control.

참고

영역에 포함 된 픽셀 컬렉션은 인접 하지 않을 수 있습니다.The collection of pixels contained with the region can be noncontiguous.
