Exemplos

O exemplo de código a seguir demonstra como você pode implementar o GetGlyphs método para desenhar objetos de glifo personalizados em uma superfície do designer de atividades.

Este exemplo de código faz parte do exemplo do SDK do Monitor de Fluxo de Trabalho do arquivo DesignerGlyphProvider.cs. Para obter mais informações, consulte Monitor de Fluxo de Trabalho.
