Exemplos

O seguinte exemplo de código cria um StatusBar controlo num formulário e adiciona dois StatusBarPanel objetos. Um dos StatusBarPanel, denominado panel1, apresenta texto de estado para uma aplicação. A segunda StatusBarPanel, chamada 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 assume que o método definido no exemplo é definido e chamado do construtor de um Form.

private:
   void CreateMyStatusBar()
   {
      // Create a StatusBar control.
      StatusBar^ statusBar1 = gcnew StatusBar;

      // Create two StatusBarPanel objects to display in the StatusBar.
      StatusBarPanel^ panel1 = gcnew StatusBarPanel;
      StatusBarPanel^ panel2 = gcnew StatusBarPanel;

      // Display the first panel with a sunken border style.
      panel1->BorderStyle = StatusBarPanelBorderStyle::Sunken;

      // Initialize the text of the panel.
      panel1->Text = "Ready...";

      // Set the AutoSize property to use all remaining space on the StatusBar.
      panel1->AutoSize = StatusBarPanelAutoSize::Spring;

      // Display the second panel with a raised border style.
      panel2->BorderStyle = StatusBarPanelBorderStyle::Raised;

      // Create ToolTip text that displays the time the application
      // was started.
      panel2->ToolTipText = System::DateTime::Now.ToShortTimeString();

      // Set the text of the panel to the current date.
      panel2->Text = "Started: " + System::DateTime::Today.ToLongDateString();

Observações

A StatusBar.StatusBarPanelCollection classe armazena os painéis exibidos no StatusBararquivo . Cada objeto na coleção é uma instância da StatusBarPanel classe que define as características e comportamentos de exibição de um painel exibido num StatusBar.

Existem várias formas de adicionar painéis à coleção. O Add método permite adicionar um único painel à coleção. Para adicionar vários painéis à coleção, cria um array de StatusBarPanel objetos e atribui-lo ao AddRange método. Se quiser inserir um painel num local específico dentro da coleção, pode usar o Insert método. Para remover painéis, pode usar o Remove método ou o RemoveAt método se souber onde o painel está localizado dentro da coleção. O Clear método permite-lhe remover todos os painéis da coleção em vez de usar o Remove método de remover um único painel de cada vez.

Para além dos métodos e propriedades para adicionar e remover painéis, StatusBar.StatusBarPanelCollection também fornece métodos para encontrar painéis dentro da coleção. O Contains método permite-lhe determinar se um painel faz parte da coleção. Depois de saber que o painel está localizado dentro da coleção, pode usar o IndexOf método para determinar onde o painel está dentro da coleção.
