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

Artigo
10/19/2023

Você pode dar aos controles do seu aplicativo uma aparência e comportamento profissionais escrevendo sua própria classe derivada do ToolStrip ToolStripProfessionalRenderer 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

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

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

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

No Windows Forms Designer, clique no botão Adicionar do ToolStrip controle e adicione um ToolStripButton ao stackStrip controle.

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

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.

No Designer de Formulários do Windows, selecione o controle StackView.
Na janela Propriedades, clique em Eventos.
Clique duas vezes no evento Carregar para gerar o manipulador de eventos StackView_Load.

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

No Designer de Formulários do Windows, selecione o controle mailStackButton.
Na janela Propriedades, clique em Eventos.
Clique duas vezes no evento Clique.

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

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

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

No Designer de Formulários do Windows, selecione o controle calendarStackButton.
Na janela Propriedades, defina o evento Clique para o manipulador de eventos stackButton_Click.
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.

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.

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.

StackView No construtor do controle, crie uma nova instância da StackRenderer classe e atribua essa instância à stackStrip propriedade do Renderer controle.

public StackView()
{
    this.InitializeComponent();

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

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

Public Sub New()
   Me.InitializeComponent()
   
   ' Assign icons to ToolStripButton controls.
   Me.InitializeImages()
   
   ' Set up renderers.
   Me.stackStrip.Renderer = New StackRenderer()
 End Sub

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).

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

Crie menus de atalho para seus controles com ContextMenuStripo . Para obter mais informações, consulte Visão geral do componente ContextMenu.
Criar um formulário com um menu padrão preenchido automaticamente. Para mais informações, consulte Instruções passo a passo: fornecendo itens de menu padrão para um formulário.
Crie um formulário de interface de vários documentos (MDI) com controles de encaixe ToolStrip . Para obter mais informações, consulte Como criar um formulário MDI com mesclagem de menu e controles ToolStrip.
