Demonstra Passo a passo: Criar um controle de ToolStrip profissionalmente com estilo

Artigo
08/04/2011

Você pode dar ao seu aplicativo ToolStrip controla uma aparência profissional e o comportamento ao escrever sua própria classe derivada da ToolStripProfessionalRenderer tipo.

Esta explicação passo a passo demonstra como usar ToolStrip controles para criar um controle composto que é semelhante a O painel de navegação fornecida pelo Microsoft ® Outlook ®. As seguintes tarefas são ilustradas nesta explicação passo a passo:

Criando um projeto de biblioteca de controle do Windows.
Projetando o controle de StackView.
Implementando um renderizador personalizado.

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

Para copiar o código deste tópico como uma única lista, consulte Como: Criar um controle de ToolStrip profissionalmente com estilo.

Observação
As caixas de diálogo e comandos de menu demonstradas podem ser diferentes daqueles descritos na Ajuda, dependendo das configurações ativas ou configurações de edição. Para alterar as configurações, escolha Import and Export Settings sobre o Ferramentas menu. Para obter mais informações, consulte Trabalhando com configurações.

Pré-requisitos

A fim de concluir este explicação passo a passo, será necessário:

Dê permissões suficientes para poder criar e executar projetos de aplicativos de Formulários do Windows no computador onde o Visual Studio está instalado.

Criando um projeto de biblioteca de controle do Windows

A primeira etapa é criar o projeto de biblioteca de controle.

Para criar o projeto de biblioteca de controle

Criar um novo projeto de biblioteca de controle do Windows chamado StackViewLibrary.
Em Solution Explorer, excluir o controle do padrão do projeto, excluindo o arquivo de origem chamado "UserControl1. cs" ou "UserControl1.vb", dependendo do idioma de sua escolha.

Para obter mais informações, consulte Como: Remover, Deletar e excluir itens.
Adicionar um novo UserControl item para o StackViewLibrary project. Nomeie o novo arquivo de fonte base de StackView.

Criar o controle de StackView

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

Para criar o controle de StackView

Da caixa de ferramentas, arraste um ToolStrip o controle para a superfície de design.

No Propriedades janela, defina a ToolStrip Propriedades de controle de acordo com a tabela a seguir.

Propriedade	Valor
Nome	stackStrip
CanOverflow	false
Dock	Bottom
Fonte	Tahoma, 10pt, style=Bold
GripStyle	Hidden
LayoutStyle	VerticalStackWithOverflow
Enchimento	0, 7, 0, 0
RenderMode	Professional

No Windows Forms Designer, clique o ToolStrip do controle Add botão e adicionar uma ToolStripButton para o stackStrip de controle.

No Propriedades janela, defina a ToolStripButton Propriedades de controle de acordo com a tabela a seguir.

Propriedade	Valor
Nome	mailStackButton
CheckOnClick	verdadeiro
CheckState	Checked
DisplayStyle	ImageAndText
ImageAlign	MiddleLeft
ImageScaling	None
ImageTransparentColor	238, 238, 238
Margin	0, 0, 0, 0
Enchimento	3, 3, 3, 3
Texto	Email
AlinhamentoDoTexto	MiddleLeft

Repita a etapa 7 para obter mais três ToolStripButton controles.

Nomear os controles calendarStackButton, contactsStackButton, e tasksStackButton. Definir o valor de Text propriedade para o calendário, contatos e tarefas, respectivamente.

Tratamento de eventos

Dois eventos são importantes para fazer a StackView controle se comportam corretamente. Lidar com o Load evento para posicionar o controle corretamente. Lidar com o Click evento para cada ToolStripButton para dar a StackView semelhante ao comportamento de estado de controle a RadioButton de controle.

Para manipular eventos

No Windows Forms Designer, selecione o StackView de controle.
No Propriedades janela, clique em eventos.
Clique duas vezes no evento Load para gerar o StackView_Load manipulador de eventos.

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

' 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

// 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;
}

No Windows Forms Designer, selecione o mailStackButton de controle.
No Propriedades janela, clique em eventos.
Clique duas vezes o evento Click.

O Windows Forms Designer gera o mailStackButton_Click manipulador de eventos.
Renomear o mailStackButton_Click o manipulador de eventos para stackButton_Click.

Para obter mais informações, consulte Como: Renomear um identificador (Visual Basic).

Insira o seguinte código para o stackButton_Click manipulador de eventos.

' 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

// 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;
        }
    }
}

No Windows Forms Designer, selecione o calendarStackButton de controle.
No Propriedades janela, defina o evento Click o stackButton_Click manipulador de eventos.
Repita as etapas 10 e 11 para o contactsStackButton e tasksStackButton controles.

Definindo ícones

Cada StackView botão tem um ícone associado. Para sua conveniência, cada ícone é representado como uma seqüência de caracteres codificadas em Base64, que é desserializado antes de um Bitmap é criado a partir do proprietário. Em um ambiente de produção, você armazena dados de bitmap como um recurso e os ícones serão exibidos no Windows Forms Designer. Para obter mais informações, consulte Como: Adicionar imagens de plano de fundo ao Windows Forms.

Para definir os ícones

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

Implementando um renderizador personalizado

Você pode personalizar a maioria dos elementos da StackView minha implementação de uma classe que deriva de controle de ToolStripRenderer classe. Neste procedimento, você irá implementar um ToolStripProfessionalRenderer classe que personaliza a alça e desenha os planos de fundo de gradientes para o ToolStripButton controles.

Para implementar um renderizador personalizado

Insira o seguinte código para o StackView definição de controle.

Esta é a definição para o StackRenderer de classe, que substitui o RenderGrip, RenderToolStripBorder, e RenderButtonBackground métodos para produzir uma aparência personalizada.

No StackView o construtor do controle, criar uma nova instância do StackRenderer de classe e atribua a essa instância para o stackStrip do controle Renderer propriedade.

Public Sub New()
   Me.InitializeComponent()

   ' Assign icons to ToolStripButton controls.
   Me.InitializeImages()

   ' Set up renderers.
   Me.stackStrip.Renderer = New StackRenderer()
 End Sub

public StackView()
{
    this.InitializeComponent();

    // Assign icons to ToolStripButton controls.
    this.InitializeImages();

    // Set up renderers.
    this.stackStrip.Renderer = new StackRenderer();
}

Testando o controle de StackView

O StackView controle deriva do UserControl classe. Portanto, você pode testar o controle com o O contêiner de teste de UserControl. Para obter mais informações, consulte Como: Teste o comportamento de tempo de execução de um UserControl.

Para testar o controle de StackView

Pressione F5 para compilar o projeto e iniciar o Contêiner de teste de UserControl.
Mova o ponteiro sobre os botões da StackView de controle e clique em um botão para ver a aparência de seu estado selecionado.

Próximas etapas

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

Criar menus de atalho para os controles com ContextMenuStrip. Para obter mais informações, consulte Visão geral do componente ContextMenu (Windows Forms).
Crie um formulário com um menu padrão automaticamente preenchido. Para obter mais informações, consulte Demonstra Passo a passo: Fornecimento de itens de Menu padrão para um formulário.
Criar um formulário MDI (interface) de documento vários com docking ToolStrip controles. Para obter mais informações, consulte Como: Criar um formulário MDI com a mesclagem de Menu e os controles ToolStrip.
