如何：向工具栏控件添加按钮

注释

ToolStrip 控件替换并添加 ToolBar 控件的功能;但是，如果选择，则保留 ToolBar 控件以实现后向兼容性和将来使用。

ToolBar 控件的一个组成部分是你在其中添加的按钮。 这些命令可用于轻松访问菜单命令，或者，也可以将其放置在应用程序用户界面的另一个区域中，以向用户公开在菜单结构中不可用的命令。

以下示例假定 ToolBar 控件已添加到 Windows 窗体（Form1）。

以编程方式添加按钮

  1. 在此过程中，通过将它们添加到 ToolBar.Buttons 集合来创建工具栏按钮。

  2. 通过通过属性传递按钮的索引 Buttons 来指定单个按钮的属性设置。

    以下示例假定窗体已添加控件 ToolBar。

    注释

    集合 ToolBar.Buttons 是一个从零开始的集合，因此代码应相应地继续。

    Public Sub CreateToolBarButtons()
' Create buttons and set text property.
   ToolBar1.Buttons.Add("One")
   ToolBar1.Buttons.Add("Two")
   ToolBar1.Buttons.Add("Three")
   ToolBar1.Buttons.Add("Four")
' Set properties of StatusBar panels.
' Set Style property.
   ToolBar1.Buttons(0).Style = ToolBarButtonStyle.PushButton
   ToolBar1.Buttons(1).Style = ToolBarButtonStyle.Separator
   ToolBar1.Buttons(2).Style = ToolBarButtonStyle.ToggleButton
   ToolBar1.Buttons(3).Style = ToolBarButtonStyle.DropDownButton
