Parâmetros

Exemplos

O exemplo de código a seguir foi projetado para uso com o Windows Forms e requer PaintEventArgse, que é um parâmetro do manipulador de eventos Paint. O código executa as seguintes ações:

• Cria o primeiro retângulo e o desenha para a tela em preto.

• Cria o segundo retângulo e o desenha para a tela em vermelho.

• Cria uma região do primeiro retângulo.

• Obtém a área de interseção para a região quando combinada com o segundo retângulo.

• Preenche a área de interseção com azul e a desenha para a tela.

Observe que apenas a área sobreposta para a região e o retângulo é azul.
