Örnekler

Aşağıdaki kod örneği, Region oluşturucu ve Exclude ve Dispose yöntemlerini gösterir.

Bu örnek, Windows Forms ile kullanılacak şekilde tasarlanmıştır. Kodu bir forma yapıştırın ve formun Paint olayını işlerken ePaintEventArgsolarak geçirerek FillRegionExcludingPath yöntemini çağırın.

private:
   void FillRegionExcludingPath( PaintEventArgs^ e )
   {
      // Create the region using a rectangle.
      System::Drawing::Region^ myRegion = gcnew System::Drawing::Region( Rectangle(20,20,100,100) );

      // Create the GraphicsPath.
      System::Drawing::Drawing2D::GraphicsPath^ path = gcnew System::Drawing::Drawing2D::GraphicsPath;

      // Add a circle to the graphics path.
      path->AddEllipse( 50, 50, 25, 25 );

      // Exclude the circle from the region.
      myRegion->Exclude( path );

      // Retrieve a Graphics object from the form.
      Graphics^ formGraphics = e->Graphics;

      // Fill the region in blue.
      formGraphics->FillRegion( Brushes::Blue, myRegion );

      // Dispose of the path and region objects.
      delete path;
      delete myRegion;
   }

private void FillRegionExcludingPath(PaintEventArgs e)

    Region myRegion = new Region(new Rectangle(20, 20, 100, 100));

    // Create the GraphicsPath.
    System.Drawing.Drawing2D.GraphicsPath path = 
        new System.Drawing.Drawing2D.GraphicsPath();

    // Add a circle to the graphics path.
    path.AddEllipse(50, 50, 25, 25);

    Graphics formGraphics = e.Graphics;

    // Fill the region in blue.
    formGraphics.FillRegion(Brushes.Blue, myRegion);

    // Dispose of the path and region objects.
    path.Dispose();
    myRegion.Dispose();
}

Private Sub FillRegionExcludingPath(ByVal e As PaintEventArgs)

    ' Create the region using a rectangle.
    Dim myRegion As New Region(New Rectangle(20, 20, 100, 100))

Örnekler

Aşağıdaki örnek, Windows Forms ile kullanılmak üzere tasarlanmıştır ve Paint olay işleyicisinin bir parametresi olan PaintEventArgsegerektirir. Kod aşağıdaki eylemleri gerçekleştirir:

• Dikdörtgen oluşturur ve siyah olarak ekrana çizer

• İlkiyle kesişen ve kırmızı renkle ekrana çizen ikinci bir dikdörtgen oluşturur.

• İlk dikdörtgeni kullanarak bir bölge oluşturur.

• İkinci dikdörtgenle birleştirildiğinde bölgenin dahil olmayan alanını alır.

• Dahil olmayan alanı maviyle doldurur ve ekrana çizer.

Bölgenin dikdörtgenle kesişmeyen alanının mavi renkli olduğuna dikkat edin.
