HOW TO：將按鈕加入至 ToolBar 控制項

注意事項：
ToolStrip 控制項會取代並且將功能加入至 ToolBar 控制項；不過您也可以選擇保留 ToolBar 控制項，以提供回溯相容性 (Backward Compatibility) 以及供未來使用。

ToolBar 控制項的一個整數部分，是您加入的按鈕。這些按鈕可用以輕鬆存取功能表命令，或是也可置於應用程式使用者介面的其他區域，將功能表結構中沒有的命令公開給您的使用者。

下面的範例假設 ToolBar 控制項已加入至 Windows Form (Form1)。

若要以程式設計方式加入按鈕

在程序中，將工具列按鈕加入至 ToolBar.Buttons 集合，建立工具列按鈕。

透過 Buttons 屬性傳遞按鈕的索引來指定個別按鈕的屬性設定。

下列範例假設已將 ToolBar 控制項加入表單。

注意事項：
ToolBar.Buttons 集合是以零起始的集合，所以程式碼要根據這點來處理。

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
' Set the ToggleButton's PartialPush property.
   ToolBar1.Buttons(2).PartialPush = True
' Instantiate a ContextMenu component and menu items.
' Set the DropDownButton's DropDownMenu property to the context menu.
   Dim cm As New ContextMenu()

   ToolBar1.Buttons(3).DropDownMenu = cm
' Set the PushButton's Pushed property.
   ToolBar1.Buttons(0).Pushed = True
' Set the ToolTipText property of one of the buttons.
