Exemplos

O seguinte exemplo de código cria um StatusBar controlo num formulário e adiciona dois StatusBarPanel objetos. Um dos StatusBarPanel objetos, chamado panel1, apresenta texto de estado para uma aplicação. O segundo StatusBarPanel objeto, chamado panel2, mostra a data atual e usa a ToolTipText propriedade da StatusBarPanel classe para mostrar a hora atual. O exemplo usa a ShowPanels propriedade para garantir que os painéis são exibidos em vez de um painel padrão, e usa e a Panels propriedade para aceder ao Add método de adicionar StatusBar.StatusBarPanelCollection os painéis ao StatusBar. O exemplo também utiliza as AutoSizepropriedades , BorderStyle, ToolTipText, e Text para inicializar os StatusBarPanel objetos. Este exemplo exige que o método definido no exemplo seja definido e chamado a partir do construtor de um Form.

Observações

O StatusBar controlo pode mostrar vários painéis para fornecer informação ao utilizador da sua aplicação. Por exemplo, um painel pode mostrar a hora atual ou o progresso de um download de ficheiro. Cada painel apresentado pelo StatusBar controlo é uma instância da StatusBarPanel classe. A Panels propriedade permite-lhe obter uma referência para a coleção de StatusBarPanel objetos que estão atualmente armazenados no StatusBar controlo. Com esta referência, pode adicionar painéis, remover painéis, aceder a um painel específico dentro da coleção e obter uma contagem dos painéis no StatusBar controlo. Para mais informações sobre as tarefas que podem ser realizadas com a coleção de painéis, consulte os StatusBar.StatusBarPanelCollection tópicos de referência da turma.
