Instruções passo a passo: criando um controle ToolStrip com estilo profissional

Você pode dar aos controles do seu aplicativo uma aparência e comportamento profissionais escrevendo sua própria classe derivada do ToolStripToolStripProfessionalRenderer tipo.

Este passo a passo demonstra como usar ToolStrip controles para criar um controle composto semelhante ao Painel de Navegação fornecido pelo Microsoft® Outlook®. As seguintes tarefas são ilustradas nesta instrução passo a passo:

  • Criar um projeto da Biblioteca de Controle do Windows.

  • Projetar o controle StackView.

  • Implementar um renderizador personalizado.

Quando tiver terminado, você terá um controle de cliente personalizado reutilizável com a aparência profissional de um controle do Microsoft Office XP.

Para copiar o código neste tópico como uma única lista, consulte Como criar um controle ToolStrip com estilo profissional.

Pré-requisitos

Você precisará do Visual Studio para concluir este passo a passo.

Criar o projeto de biblioteca de controle

  1. No Visual Studio, crie um novo projeto da Biblioteca de Controle do Windows chamado StackViewLibrary.

  2. No Gerenciador de Soluções, exclua o controle padrão do projeto excluindo o arquivo de origem denominado "UserControl1.cs" ou "UserControl1.vb", dependendo da linguagem de sua escolha.

    Para obter mais informações, consulte Como: remover, excluir e excluir itens.

  3. Adicione um novo UserControl item ao projeto StackViewLibrary . Dê ao novo arquivo de origem o nome base StackView.

Projetar o controle StackView

O StackView controle é um controle composto com um controle filho ToolStrip . Para obter mais informações sobre controles de composição, consulte Variedades de controles personalizados.

  1. Na Caixa de Ferramentas, arraste um ToolStrip controle para a superfície de design.

  2. Na janela Propriedades, defina as ToolStrip propriedades do controle de acordo com a tabela a seguir.

    Propriedade Valor
    Nome stackStrip
    CanOverflow false
    Encaixar Bottom
    Fonte Tahoma, 10pt, style=Bold
    GripStyle Hidden
    LayoutStyle VerticalStackWithOverflow
    Preenchimento 0, 7, 0, 0
    RenderMode Professional
  3. No Windows Forms Designer, clique no botão Adicionar do ToolStrip controle e adicione um ToolStripButton ao stackStrip controle.

  4. Na janela Propriedades, defina as ToolStripButton propriedades do controle de acordo com a tabela a seguir.

    Propriedade Valor
    Nome mailStackButton
    CheckOnClick true
    CheckState Checked
    DisplayStyle ImageAndText
    ImageAlign MiddleLeft
    ImageScaling None
    ImageTransparentColor 238, 238, 238
    Margem 0, 0, 0, 0
    Preenchimento 3, 3, 3, 3
    Texto Email
    TextAlign MiddleLeft
  5. Repita a etapa 7 para mais ToolStripButton três controles.

    Nomeie os controles como calendarStackButton, contactsStackButton e tasksStackButton. Defina o valor da Text propriedade como Calendário, Contatos e Tarefas, respectivamente.

Tratar eventos

Dois eventos são importantes para fazer com que o controle StackView se comporte corretamente. Manipule o evento para posicionar o Load controle corretamente. Manipule o Click evento para cada um ToolStripButton para dar ao comportamento de estado de controle semelhante ao StackViewRadioButton controle.

  1. No Designer de Formulários do Windows, selecione o controle StackView.

  2. Na janela Propriedades, clique em Eventos.

  3. Clique duas vezes no evento Carregar para gerar o manipulador de eventos StackView_Load.

  4. No manipulador de eventos StackView_Load, copie e cole o código a seguir.

    // This method handles the Load event for the UserControl.
    private void StackView_Load(object sender, EventArgs e)
    {
        // Dock bottom.
        this.Dock = DockStyle.Bottom;
    
        // Set AutoSize.
        this.AutoSize = true;
    }
    
    ' This method handles the Load event for the UserControl.
    Private Sub StackView_Load(sender As Object, e As EventArgs) Handles MyBase.Load
       ' Dock bottom.
       Me.Dock = DockStyle.Bottom
       
       ' Set AutoSize.
       Me.AutoSize = True
     End Sub
    
  5. No Designer de Formulários do Windows, selecione o controle mailStackButton.

  6. Na janela Propriedades, clique em Eventos.

  7. Clique duas vezes no evento Clique.

    O Designer de Formulários do Windows gera o manipulador de eventos mailStackButton_Click.

  8. Renomeie o manipulador de eventos mailStackButton_Click como stackButton_Click.

    Para obter mais informações, consulte Renomear uma refatoração de símbolo de código.

  9. Adicione o seguinte código ao manipulador de eventos stackButton_Click.

    // This method handles the Click event for all
    // the ToolStripButton controls in the StackView.
    private void stackButton_Click(object sender, EventArgs e)
    {
        // Define a "one of many" state, similar to
        // the logic of a RadioButton control.
        foreach (ToolStripItem item in this.stackStrip.Items)
        {
            if ((item != sender) &&
                (item is ToolStripButton))
            {
                ((ToolStripButton)item).Checked = false;
            }
        }
    }
    
    ' This method handles the Click event for all
    ' the ToolStripButton controls in the StackView.
    Private Sub stackButton_Click(sender As Object, e As EventArgs) Handles mailStackButton.Click, calendarStackButton.Click, contactsStackButton.Click, tasksStackButton.Click
       ' Define a "one of many" state, similar to
       ' the logic of a RadioButton control.
       Dim item As ToolStripItem
       For Each item In  Me.stackStrip.Items
             If item IsNot sender AndAlso TypeOf item Is ToolStripButton Then
                 CType(item, ToolStripButton).Checked = False
             End If
       Next item
     End Sub
    
  10. No Designer de Formulários do Windows, selecione o controle calendarStackButton.

  11. Na janela Propriedades, defina o evento Clique para o manipulador de eventos stackButton_Click.

  12. Repita as etapas 10 e 11 para os controles contactsStackButton e tasksStackButton.

Definir icons

Cada botão StackView tem um ícone associado. Por conveniência, cada ícone é representado como uma cadeia de caracteres codificada em Base64, que é desserializada antes de um Bitmap ser criado a partir dele. Em um ambiente de produção, armazene dados de bitmap como um recurso e seus ícones serão exibidos no Designer de Formulários do Windows. Para obter mais informações, consulte Como adicionar imagens de tela de fundo ao Windows Forms.

  1. No Editor de Códigos, insira o seguinte código na definição de classe StackView. Esse código inicializa os bitmaps para os ToolStripButton ícones.

    private static Bitmap mailBmp;
    private static Bitmap calendarBmp;
    private static Bitmap contactsBmp;
    private static Bitmap tasksBmp;

Implementar um renderizador personalizado

Você pode personalizar a StackView maioria dos elementos do controle my implementando uma classe que deriva da ToolStripRenderer classe. Neste procedimento, você implementará uma ToolStripProfessionalRenderer classe que personaliza a aderência e desenha planos de fundo de gradiente para os ToolStripButton controles.

  1. Insira o seguinte código na definição de controle StackView.

    Essa é a definição da StackRenderer classe, que substitui os RenderGripmétodos , RenderToolStripBordere RenderButtonBackground para produzir uma aparência personalizada.

    internal class StackRenderer : ToolStripProfessionalRenderer

Testar o controle StackView

O StackView controle deriva da UserControl classe. Portanto, você pode testar o controle com o Contêiner de teste do UserControl. Para obter mais informações, consulte How to: Test the Run-Time Behavior of a UserControl (Como testar o comportamento de tempo de execução de um UserControl).

  1. Pressione F5 para compilar o projeto e iniciar o contêiner de teste UserControl.

  2. Mova o ponteiro sobre os botões do controle StackView e, em seguida, clique em um botão para ver a aparência de seu estado selecionado.

Próximas etapas

Neste passo a passo, você criou controle de cliente personalizado reutilizável com a aparência profissional de um controle do Office XP. Você pode usar a ToolStrip família de controles para muitas outras finalidades:
