Обновлен: Ноябрь 2007

Чтобы придать элементам управления приложения ToolStrip профессиональный внешний вид и поведение, создайте собственный класс на основе типа ToolStripProfessionalRenderer.

В этом пошаговом руководстве демонстрируется использование элементов управления ToolStrip для создания составного элемента управления, напоминающего Область переходов в Microsoft® Outlook®. В этом пошаговом руководстве проиллюстрированы следующие задачи:

Создание проекта "Библиотека элементов управления Windows"
Разработка элемента управления StackView
Реализация настраиваемого средства визуализации

По завершении работы с этим примером создается пользовательский клиентский элемент управления, доступный для многократного использования, имеющий профессиональный внешний вид элемента управления Microsoft Office® XP.

Обязательные компоненты

Для выполнения этого пошагового руководства потребуется:

Разрешения, необходимые для создания и выполнения проектов приложения Windows Forms на компьютере, на котором установлена Visual Studio.

Создание проекта "Библиотека элементов управления Windows"

На первом этапе необходимо создать проект библиотеки элементов управления.

Чтобы создать проект библиотеки элемента управления

Создайте новый проект библиотеки элементов управления Windows под названием StackViewLibrary.
В Обозревателе решений удалите элемент управления по умолчанию для этого проекта, удалив исходный файл "UserControl1.cs" или "UserControl1.vb" в зависимости от выбранного языка.

Дополнительные сведения см. в разделе Практическое руководство. Устранение, удаление и исключение элементов.
Добавьте новый элемент UserControl в проект StackViewLibrary. Назовите новый исходный файл StackView.

Разработка элемента управления StackView

Элемент управления StackView – это составной элемент управления, содержащий один дочерний элемент управления ToolStrip. Дополнительные сведения о составных элементах управления см. в разделе Создание собственных элементов управления.

Чтобы разработать элемент управления StackView

Перетащите элемент управления ToolStrip из панели элементов на поверхность разработки.

В окне Свойства задайте свойства элемента управления ToolStrip в соответствии со следующей таблицей.

Свойство	Значение
Name	stackStrip
CanOverflow	false
Dock	Bottom
Font	Tahoma, 10pt, style=Bold
GripStyle	Hidden
LayoutStyle	VerticalStackWithOverflow
Padding	0, 7, 0, 0
RenderMode	Professional

В конструкторе Windows Forms щелкните кнопку Добавить для элемента управления ToolStrip и добавьте ToolStripButton к элементу управления stackStrip.

В окне Свойства задайте свойства элемента управления ToolStripButton в соответствии со следующей таблицей.

Свойство	Значение
Name	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
Text	Почта
TextAlign	MiddleLeft

Повторите шаг 7 для еще трех элементов управления ToolStripButton.

Назовите элементы управления calendarStackButton, contactsStackButton и tasksStackButton. Укажите для свойства Text значения Календарь, Контакты и Задачи соответственно.

Обработка событий

Для обеспечения корректного поведения элемента управления StackView важны два события. Обработайте событие Load для правильного размещения элемента управления. Обработайте событие Click для каждой кнопки ToolStripButton, чтобы поведение состояния элемента управления StackView стало похожим на элемент управления RadioButton.

Чтобы обработать события

В конструкторе Windows Forms выберите элемент управления StackView.
В окне Свойства щелкните События.
Дважды щелкните событие "Load" для создания обработчика события StackView_Load.

В обработчике события StackView_Load скопируйте и вставьте следующий код.

' 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;
}

В конструкторе Windows Forms выберите элемент управления mailStackButton.
В окне Свойства щелкните События.
Дважды щелкните событие "Click".

Конструктор Windows Forms генерирует обработчик события для события mailStackButton_Click.
Измените имя обработчика события mailStackButton_Click на stackButton_Click.

Дополнительные сведения см. в разделе Практическое руководство. Переименование идентификатора.

Вставьте следующий код в обработчик события 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;
        }
    }
}

Определение значков

Каждой кнопке StackView назначается определенный значок. Для удобства каждый значок представлен как строка в кодировке Base64, которая десериализуется до создания Bitmap на ее основе. В производственной среде данные точечных рисунков хранятся как ресурс, и значки отображаются в конструкторе Windows Forms. Дополнительные сведения см. в разделе Практическое руководство. Добавление фоновых изображений в формы Windows Forms..

Чтобы определить значки

В редакторе кода вставьте следующий код в определение класса StackView. Этот код инициализирует точечные рисунки для значков ToolStripButton.

Реализация настраиваемого средства визуализации

Большую часть элементов элемента управления StackView можно настроить, реализовав класс на основе класса ToolStripRenderer. В этой процедуре необходимо реализовать класс ToolStripProfessionalRenderer, используемый для настройки захвата и изображения градиентного фона для элементов управления ToolStripButton.

Чтобы реализовать настраиваемое средство визуализации

Вставьте следующий код в определение элемента управления StackView.

Это определение для класса StackRenderer, который переопределяет методы RenderGrip, RenderToolStripBorder и RenderButtonBackground для создания настраиваемого внешнего вида.

В конструкторе элемента управления StackView создайте новый экземпляр класса StackRenderer и назначьте этот экземпляр свойству Renderer элемента управления 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();
}

Тестирование элемента управления StackView

Элемент управления StackView является производным от класса UserControl. Следовательно, этот элемент управления можно тестировать с использованием Тестового контейнера пользовательских элементов управления. Дополнительные сведения см. в разделе Практическое руководство. Тестирование поведения элемента UserControl во время выполнения.

Чтобы протестировать элемент управления StackView

Нажмите клавишу F5 для построения проекта и запуска Тестового контейнера пользовательских элементов управления.
Поместите указатель мыши над кнопками элемента управления StackView, а затем щелкните кнопку для просмотра внешнего вида выбранного для нее состояния.

Следующие действия

В этом пошаговом руководстве был создан пользовательский клиентский элемент управления, допускающий многократное использование и имеющий профессиональный внешний вид элемента управления Office XP. Семейством элементов управления ToolStrip можно также пользоваться для многих других целей:

Создайте контекстное меню для своих элементов управления с помощью ContextMenuStrip. Дополнительные сведения см. в разделе Общие сведения о компоненте ContextMenu (Windows Forms).
Создайте форму с автоматически заполняемым стандартным меню. Дополнительные сведения см. в разделе Пошаговое руководство. Создание стандартных пунктов меню для формы.
Создайте форму многодокументного интерфейса MDI с закрепленными элементами управления ToolStrip. Дополнительные сведения см. в разделе Практическое руководство. Создание формы MDI путем слияния меню и с применением и элементов управления ToolStrip.
