Tutorial: Crear un control ToolStrip de estilo profesional

Artículo
05/04/2023

Puede asignar a los controles ToolStrip de la aplicación un aspecto y comportamiento profesionales si escribe una clase propia derivada del tipo ToolStripProfessionalRenderer.

En el ejemplo de código siguiente se muestra cómo usar controles ToolStrip para crear un control compuesto similar al panel de navegación de Microsoft® Outlook®. En este tutorial se ilustran las tareas siguientes:

Creación de un proyecto de Biblioteca de controles de Windows.
Diseño del control StackView.
Implementación de un representador personalizado.

Cuando haya terminado, tendrá un control de cliente personalizado reutilizable con la apariencia profesional de un control de Microsoft Office® XP.

Para copiar el código de este tema como una sola lista, vea Procedimiento para crear un control ToolStrip de estilo profesional.

Requisitos previos

Necesitará Visual Studio para completar este tutorial.

Creación del proyecto de biblioteca de controles

En Visual Studio, cree un proyecto de Biblioteca de controles de Windows denominado StackViewLibrary.
En el Explorador de soluciones, elimine el control predeterminado del proyecto mediante la eliminación del archivo de código fuente denominado "UserControl1.cs" o "UserControl1.vb", en función del lenguaje que haya elegido.

Para más información, vea Procedimiento para quitar, eliminar y excluir elementos.
Agregue un nuevo elemento UserControl al proyecto StackViewLibrary. Asigne el nombre base StackView al nuevo archivo de código fuente.

Diseño del control StackView

StackView es un control compuesto con un control ToolStrip secundario. Para más información sobre los controles compuestos, vea Variedades de controles compuestos.

Desde el Cuadro de herramientas, arrastre un control ToolStrip hasta la superficie de diseño.

En la ventana Propiedades, establezca las propiedades del control ToolStrip según la tabla siguiente.

Propiedad	Valor
Nombre	`stackStrip`
CanOverflow	`false`
Acoplar	Bottom
Fuente	`Tahoma, 10pt, style=Bold`
GripStyle	Hidden
LayoutStyle	VerticalStackWithOverflow
Relleno	`0, 7, 0, 0`
RenderMode	Professional

En el Diseñador de Windows Forms, haga clic en el botón Agregar del control ToolStrip y agregue un elemento ToolStripButton al control stackStrip.

En la ventana Propiedades, establezca las propiedades del control ToolStripButton según la tabla siguiente.

Propiedad	Valor
Nombre	`mailStackButton`
CheckOnClick	true
CheckState	Checked
DisplayStyle	ImageAndText
ImageAlign	MiddleLeft
ImageScaling	None
ImageTransparentColor	`238, 238, 238`
Margen	`0, 0, 0, 0`
Relleno	`3, 3, 3, 3`
Texto	Correo
TextAlign	MiddleLeft

Repita el paso 7 para tres controles ToolStripButton más.

Asigne a los controles los nombres calendarStackButton, contactsStackButton y tasksStackButton. Establezca el valor de la propiedad Text en Calendario, Contactos y Tareas, respectivamente.

Control de eventos

Hay dos evento importantes para que el control StackView se comporte correctamente. Controle el evento Load para colocar el control correctamente. Controle el evento Click de cada objeto ToolStripButton para asignar al control StackView un comportamiento de estado similar al del control RadioButton.

En el Diseñador de Windows Forms, seleccione el control StackView.
En la ventana Propiedades, haga clic en Eventos.
Haga doble clic en el evento Load para generar el controlador de eventos StackView_Load.

En el controlador de eventos StackView_Load, copie y pegue el siguiente código.

// 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

En el Diseñador de Windows Forms, seleccione el control mailStackButton.
En la ventana Propiedades, haga clic en Eventos.
Haga doble clic en el evento Click.

El Diseñador de Windows Forms genera el controlador de eventos mailStackButton_Click.
Cambie el nombre del controlador de eventos mailStackButton_Click a stackButton_Click.

Para más información, vea Cambio del nombre de un símbolo de código de refactorización.

Inserte el código siguiente en el controlador 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

En el Diseñador de Windows Forms, seleccione el control calendarStackButton.
En la ventana Propiedades, establezca el evento Click en el controlador de eventos stackButton_Click.
Repita los pasos 10 y 11 para los controles contactsStackButton y tasksStackButton.

Definición de iconos

Cada botón StackView tiene un icono asociado. Para mayor comodidad, cada icono se representa como una cadena codificada en Base64, que se deserializa antes de crear a un objeto Bitmap partir de ella. En un entorno de producción, los datos de mapa de bits se almacenan como un recurso y los iconos aparecen en el Diseñador de Windows Forms. Para más información, vea Procedimiento para agregar imágenes de fondo a Windows Forms.

En el Editor de código, inserte el código siguiente en la definición de la clase StackView. Este código inicializa los mapas de bits de los iconos ToolStripButton.

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

Implementación de un representador personalizado

Puede personalizar la mayoría de los elementos del control StackView mediante la implementación de una clase derivada de la clase ToolStripRenderer. En este procedimiento, implementará una clase ToolStripProfessionalRenderer que personaliza el control de ajuste y dibuja fondos degradados para los controles ToolStripButton.

Inserte el código siguiente en la definición del control StackView.

Esta es la definición de la clase StackRenderer, que invalida los métodos RenderGrip, RenderToolStripBorder y RenderButtonBackground para generar una apariencia personalizada.

En el constructor del control StackView, cree una instancia de la clase StackRenderer y asigne esta instancia a la propiedad Renderer del control stackStrip.

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

Prueba del control StackView

El control StackView deriva de la clase UserControl. Por tanto, puede probar el control con el contenedor de pruebas de UserControl. Para más información, consulte Cómo: Comprobar el comportamiento de un control de usuario en tiempo de ejecución.

Presione F5 para compilar el proyecto e iniciar el contenedor de pruebas UserControl.
Mueva el puntero sobre los botones del control StackView y, después, haga clic en un botón para ver la apariencia de su estado seleccionado.

Pasos siguientes

En este tutorial, ha creado un control de cliente personalizado reutilizable con la apariencia profesional de un control de Office XP. Puede usar la familia de controles ToolStrip para muchos otros fines:

Crear menús contextuales de los controles con ContextMenuStrip. Para más información, vea Información general sobre el componente ContextMenu.
Crear un formulario con un menú estándar rellenado de forma automática. Para más información, vea Tutorial: Proporcionar elementos de menú estándar a un formulario.
Crear un formulario de interfaz de múltiples documentos (MDI) con controles ToolStrip acoplados. Para más información, vea Procedimiento para crear un formulario MDI con combinación de menús y controles ToolStrip.
