Procédure pas à pas : création d'un contrôle ToolStrip de style professionnel

Article
08/10/2011

Vous pouvez donner une apparence et un comportement professionnels aux contrôles ToolStrip de votre application en écrivant votre propre classe dérivée du type ToolStripProfessionalRenderer.

Cette procédure pas à pas montre comment utiliser des contrôles ToolStrip pour créer un contrôle composite qui ressemble au Volet de navigation fourni par Microsoft® Outlook®. Les tâches suivantes sont illustrées dans cette procédure pas à pas :

Création d'un projet Bibliothèque de contrôles Windows.
Conception du contrôle StackView.
Implémentation d'un convertisseur personnalisé.

Lorsque vous avez terminé, vous disposez d'un contrôle client personnalisé réutilisable doté de l'apparence professionnelle d'un contrôle Microsoft Office® XP.

Pour copier le code dans cette rubrique sous forme de liste unique, consultez Comment : créer un contrôle ToolStrip de style professionnel.

Notes

Les boîtes de dialogue et les commandes de menu qui s'affichent peuvent être différentes de celles qui sont décrites dans l'aide, en fonction de vos paramètres actifs ou de l'édition utilisée. Pour modifier vos paramètres, choisissez Importation et exportation de paramètres dans le menu Outils. Pour plus d'informations, consultez Utilisation des paramètres.

Composants requis

Pour exécuter cette procédure pas à pas, vous devrez :

Avoir des autorisations suffisantes pour être en mesure de créer et d'exécuter des projets d'application Windows Forms sur l'ordinateur où Visual Studio est installé.

Création d'un projet Bibliothèque de contrôles Windows.

La première étape consiste à créer le projet Bibliothèque de contrôles.

Pour créer le projet de bibliothèque de contrôles

Créez un projet Bibliothèque de contrôles Windows appelé StackViewLibrary.
Dans l'Explorateur de solutions, supprimez le contrôle par défaut du projet en supprimant le fichier source nommé "UserControl1.cs" ou "UserControl1.vb", selon le langage de votre choix.

Pour plus d'informations, consultez Comment : supprimer et exclure des éléments.
Ajoutez un nouvel élément UserControl au projet StackViewLibrary. Donnez le nom de base StackView au nouveau fichier source.

Conception du contrôle StackView

Le contrôle StackView est un contrôle composite doté d'un contrôle ToolStrip enfant. Pour plus d'informations sur les contrôles composites, consultez Variétés de contrôles personnalisés.

Pour concevoir le contrôle StackView

Depuis la Boîte à outils, faites glisser un contrôle ToolStrip vers l'aire de conception.

Dans la fenêtre Propriétés, définissez les propriétés du contrôle ToolStrip en fonction du tableau suivant.

Propriété	Valeur
Nom	stackStrip
CanOverflow	false
Dock	Bottom
Police	Tahoma, 10pt, style=Bold
GripStyle	Hidden
LayoutStyle	VerticalStackWithOverflow
Padding	0, 7, 0, 0
RenderMode	Professional

Dans le Concepteur Windows Forms, cliquez sur le bouton Ajouter du contrôle ToolStrip et ajoutez un ToolStripButton au contrôle stackStrip.

Dans la fenêtre Propriétés, définissez les propriétés du contrôle ToolStripButton en fonction du tableau suivant.

Propriété	Valeur
Nom	mailStackButton
CheckOnClick	true
CheckState	Checked
DisplayStyle	ImageAndText
ImageAlign	MiddleLeft
ImageScaling	None
ImageTransparentColor	238, 238, 238
Margin	0, 0, 0, 0
Padding	3, 3, 3, 3
Texte	Courrier
TextAlign	MiddleLeft

Répétez l'étape 7 pour trois contrôles ToolStripButton supplémentaires.

Nommez les contrôles calendarStackButton, contactsStackButton et tasksStackButton. Affectez à la propriété Text les valeurs Calendrier, Contacts et Tâches, respectivement.

Gestion des événements

Pour que le contrôle StackView se comporte correctement, deux événements sont nécessaires. Gérez l'événement Load pour positionner le contrôle correctement. Gérez l'événement Click pour chaque ToolStripButton afin de donner à l'état du contrôle StackView un comportement identique au contrôle RadioButton.

Pour gérer des événements

Dans le Concepteur Windows Forms, sélectionnez le contrôle StackView.
Dans la fenêtre Propriétés, cliquez sur Événements.
Double-cliquez sur l'événement Load pour générer le gestionnaire d'événements StackView_Load.

Dans le gestionnaire d'événements StackView_Load, copiez et collez le code suivant.

' 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;
}

Dans le Concepteur Windows Forms, sélectionnez le contrôle mailStackButton.
Dans la fenêtre Propriétés, cliquez sur Événements.
Double-cliquez sur l'événement Click.

Le Concepteur Windows Forms génère le gestionnaire d'événements mailStackButton_Click.
Remplacez le nom du gestionnaire d'événements mailStackButton_Click par stackButton_Click.

Pour plus d'informations, consultez Comment : renommer un identificateur (Visual Basic).

Insérez le code suivant dans le gestionnaire d'événements stackButton_Click.

' 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;
        }
    }
}

Dans le Concepteur Windows Forms, sélectionnez le contrôle calendarStackButton.
Dans la fenêtre Propriétés, affectez à l'événement Click le gestionnaire d'événements stackButton_Click.
Répétez les étapes 10 et 11 pour les contrôles contactsStackButton et tasksStackButton.

Définition d'icônes

Chaque bouton StackView a une icône associée. Pour plus de facilité, chaque icône est représentée sous forme de chaîne encodée en base64 qui est désérialisée avant qu'un Bitmap ne soit créé à partir de celle-ci. Dans un environnement de production, vous stockez des données Bitmap en tant que ressource et vos icônes s'affichent dans le Concepteur Windows Forms. Pour plus d'informations, consultez Comment : ajouter des images d'arrière-plan à des Windows Forms.

Pour définir des icônes

Dans l'éditeur de code, insérez le code suivant dans la définition de classe StackView. Ce code initialise les bitmaps pour les icônes ToolStripButton.

Implémentation d'un convertisseur personnalisé

Vous pouvez personnaliser la plupart des éléments du contrôle StackView en implémentant une classe qui dérive de la classe ToolStripRenderer. Dans cette procédure, vous implémenterez une classe ToolStripProfessionalRenderer qui personnalise la poignée et dessine des arrière-plans dégradés pour les contrôles ToolStripButton.

Pour implémenter un convertisseur personnalisé

Insérez le code suivant dans la définition du contrôle StackView.

Il s'agit de la définition de la classe StackRenderer qui substitue les méthodes RenderGrip, RenderToolStripBorder et RenderButtonBackground afin de produire une apparence personnalisée.

Dans le constructeur du contrôle StackView, créez une nouvelle instance de la classe StackRenderer et assignez-la à la propriété Renderer du contrôle stackStrip.

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();
}

Test du contrôle StackView

Le contrôle StackView dérive de la classe UserControl. Par conséquent, vous pouvez tester le contrôle à l'aide du Conteneur de test UserControl. Pour plus d'informations, consultez Comment : tester le comportement d'un UserControl au moment de l'exécution.

Pour tester le contrôle StackView

Appuyez sur F5 pour générer le projet et lancer le Conteneur de test UserControl.
Déplacez le pointeur sur les boutons du contrôle StackView, puis cliquez sur un bouton pour visualiser l'apparence de son état sélectionné.

Étapes suivantes

Dans cette procédure pas à pas, vous avez créé un contrôle client personnalisé réutilisable doté de l'apparence professionnelle d'un contrôle Office XP. Vous pouvez utiliser la famille de contrôles ToolStrip à bien d'autres fins :

Créer des menus contextuels pour vos contrôles avec ContextMenuStrip. Pour plus d'informations, consultez Vue d'ensemble du composant ContextMenu (Windows Forms).
Créer un formulaire doté d'un menu standard automatiquement rempli. Pour plus d'informations, consultez Procédure pas à pas : mise à disposition d'éléments de menu standard pour un formulaire.
Créez un formulaire d'interface multidocument (MDI) avec des contrôles d'ancrage ToolStrip. Pour plus d'informations, consultez Comment : créer un formulaire MDI avec la fusion de menus et des contrôles ToolStrip.
