ToolTip 类编程介绍

下面的代码示例创建一个 ToolTip 类的实例，并将该实例与创建它时所在的 Form 相关联。代码随后初始化延迟属性 AutoPopDelay、InitialDelay 和 ReshowDelay。另外，ToolTip 类的实例将 ShowAlways 属性设置为 true，以使工具提示文本始终显示而不管窗体是否活动。最后，该示例将工具提示文本与窗体上的 Button 和 CheckBox 这两个控件关联。本代码示例要求示例中定义的方法位于 Form 之内，而该窗体应包含一个名为 button1 的 Button 控件和一个名为 checkBox1 的 CheckBox 控件，并且要求从 Form 的构造函数中调用该方法。

Visual Basic

' This example assumes that the Form_Load event handling method
' is connected to the Load event of the form.
Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles MyBase.Load
   ' Create the ToolTip and associate with the Form container.
   Dim toolTip1 As New ToolTip()
   
   ' Set up the delays for the ToolTip.
   toolTip1.AutoPopDelay = 5000
   toolTip1.InitialDelay = 1000
   toolTip1.ReshowDelay = 500
   ' Force the ToolTip text to be displayed whether or not the form is active.
   toolTip1.ShowAlways = True
   
   ' Set up the ToolTip text for the Button and Checkbox.
   toolTip1.SetToolTip(Me.button1, "My button1")
   toolTip1.SetToolTip(Me.checkBox1, "My checkBox1")
