Exemplos

O exemplo de código a seguir demonstra como usar o ListView recurso de lado a lado. No exemplo, o modo de exibição de bloco exibe itens que representam livros. Cada item é mostrado como um bloco que contém um ícone de um livro, o título, o autor e o ano de publicação. Para que o código de exemplo funcione, você deve incluir um arquivo de ícone chamado Book.ico no mesmo diretório que o exemplo. Para ver a exibição de bloco sem ícones, comente as linhas relacionadas ao ImageList objeto.
