演练：创建具有专业样式的 ToolStrip 控件

项目
08/12/2011

可以为应用程序的 ToolStrip 控件提供专业的外观和行为，方法是编写从 ToolStripProfessionalRenderer 类型派生的您自己的类。

本演练演示如何使用 ToolStrip 控件创建类似于 Microsoft® Outlook® 提供的**“导航窗格”**的复合控件。本演练演示了以下任务：

创建一个 Windows 控件库项目。
设计 StackView 控件。
实现自定义呈现器。

完成后，您将拥有可重用的自定义客户端控件，该控件具有 Microsoft Office® XP 控件的专业外观。

若要将本主题中的代码复制为单个列表，请参见如何：创建具有专业样式的 ToolStrip 控件。

提示

显示的对话框和菜单命令可能会与“帮助”中的描述不同，具体取决于您现用的设置或版本。若要更改设置，请在“工具”菜单上选择“导入和导出设置”。有关更多信息，请参见使用设置。

系统必备

若要完成本演练，您需要：

足以在安装了 Visual Studio 的计算机上创建和运行 Windows 窗体应用程序项目的权限。

创建 Windows 控件库项目

第一步是创建控件库项目。

创建控件库项目

创建一个名为 StackViewLibrary 的新的 Windows 控件库项目。
在**“解决方案资源管理器”**中，通过删除名为“UserControl1.cs”或“UserControl1.vb”的源文件来删除项目的默认控件，具体删除哪个源文件取决于您选择的语言。

有关更多信息，请参见如何：移除、删除和排除项。
向**“StackViewLibrary”**项目添加新的 UserControl 项。将新源文件的基名称命名为 StackView。

设计 StackView 控件

StackView 控件是具有一个子 ToolStrip 控件的复合控件。有关复合控件的更多信息，请参见各种自定义控件。

设计 StackView 控件

将 ToolStrip 控件从**“工具箱”**中拖动到设计图面。

在**“属性”**窗口中，根据下表设置 ToolStrip 控件的属性。

属性	值
Name	stackStrip
CanOverflow	false
Dock	Bottom
字体	Tahoma, 10pt, style=Bold
GripStyle	Hidden
LayoutStyle	VerticalStackWithOverflow
Padding	0, 7, 0, 0
RenderMode	Professional

在 Windows 窗体设计器中，单击 ToolStrip 控件的**“添加”**按钮并向 stackStrip 控件添加一个 ToolStripButton。

在**“属性”**窗口中，根据下表设置 ToolStripButton 控件的属性。

属性	值
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	邮件
TextAlign	MiddleLeft

对于另外三个 ToolStripButton 控件，请重复步骤 7。

为控件 calendarStackButton、contactsStackButton 和 tasksStackButton 命名。将 Text 属性值分别设置为“日历”、“联系人”和“任务”。

处理事件

为使 StackView 控件正常运行，有两个事件非常重要。处理 Load 事件可正确定位控件。处理每个 ToolStripButton 的 Click 事件可使 StackView 控件的状态行为类似于 RadioButton 控件。

处理事件

在 Windows 窗体设计器中，选择 StackView 控件。
在**“属性”窗口中，单击“事件”**。
双击 Load 事件以生成 StackView_Load 事件处理程序。

在 StackView_Load 事件处理程序中，复制并粘贴下面的代码。

' 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;
}

在 Windows 窗体设计器中，选择 mailStackButton 控件。
在**“属性”窗口中，单击“事件”**。
双击“Click”事件。

Windows 窗体设计器将生成 mailStackButton_Click 事件处理程序。
将 mailStackButton_Click 事件处理程序重命名为 stackButton_Click。

有关更多信息，请参见如何：重命名标识符 (Visual Basic)。

将下面的代码插入到 stackButton_Click 事件处理程序中。

' 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;
        }
    }
}

在 Windows 窗体设计器中，选择 calendarStackButton 控件。
在**“属性”**窗口中，将“Click”事件设置为 stackButton_Click 事件处理程序。
对 contactsStackButton 和 tasksStackButton 控件重复步骤 10 和 11。

定义图标

每个 StackView 按钮都有一个关联的图标。为方便起见，每个图标都表示为以 Base64 编码的字符串，在根据该字符串创建 Bitmap 之前，将反序列化该字符串。在生产环境中，位图数据将作为资源存储，图标将显示在 Windows 窗体设计器中。有关更多信息，请参见如何：向 Windows 窗体添加背景图像。

定义图标

在代码编辑器中，将以下代码插入到 StackView 类定义中。此代码初始化 ToolStripButton 图标的位图。

在 StackView 类构造函数中添加对 InitializeImages 方法的调用。

}

实现自定义呈现器

通过实现从 ToolStripRenderer 类中派生的类，可以自定义 StackView 控件的大多数元素。在此过程中，将会实现 ToolStripProfessionalRenderer 类，该类用于自定义手柄并绘制 ToolStripButton 控件的渐变背景。

实现自定义呈现器

将下面的代码插入到 StackView 控件定义中。

这是 StackRenderer 类的定义，该定义重写了 RenderGrip、RenderToolStripBorder 和 RenderButtonBackground 方法以产生自定义外观。

在 StackView 控件的构造函数中创建 StackRenderer 类的新实例，并将此实例分配给 stackStrip 控件的 Renderer 属性。

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();
}

测试 StackView 控件

StackView 控件从 UserControl 类中派生。因此，可以使用**“UserControl 测试容器”**测试控件。有关更多信息，请参见如何：测试 UserControl 的运行时行为。

测试 StackView 控件

按 F5 以生成项目并启动**“UserControl 测试容器”**。
将指针移到 StackView 控件的按钮上方，然后单击任一按钮以查看其选定状态的外观。

后续步骤

在本演练中，您已经创建了具有 Office XP 控件专业外观的可重用自定义客户端控件。 ToolStrip 系列控件有很多其他用途：

使用 ContextMenuStrip 来创建控件的快捷菜单。有关更多信息，请参见 ContextMenu 组件概述（Windows 窗体）。
创建一个自动填充有标准菜单的窗体。有关更多信息，请参见演练：向窗体提供标准菜单项。
创建包含停靠的 ToolStrip 控件的多文档界面 (MDI) 窗体。有关更多信息，请参见如何：创建合并了菜单并具有 ToolStrip 控件的 MDI 窗体。
