Parâmetros

Devoluções

A Size que contém o tamanho especificado pelo type parâmetro para a parte atual do estilo visual.

Exceções

Exemplos

O exemplo de código seguinte demonstra como usar o GetPartSize(IDeviceContext, ThemeSizeType) método num controlo personalizado para obter os tamanhos de uma janela na barra de título, botão de fechar , bordas e alavanca de dimensionamento especificados pelo estilo visual. Estes tamanhos são usados para calcular os tamanhos dos Rectangle objetos usados para desenhar os VisualStyleElement objetos que representam estas partes da janela. Este exemplo de código faz parte de um exemplo maior fornecido para a VisualStyleRenderer visão geral da classe.
