示例

下面的两个示例演示如何使用 InPlaceVisibilityChanging。

第一个示例将 InPlaceVisibilityChanging 事件处理程序 tip_InPlaceVisibilityChanging 附加到 TextInputPanel 对象 tip。

AddHandler tip.InPlaceVisibilityChanging, AddressOf tip_InPlaceVisibilityChanging

tip.InPlaceVisibilityChanging += new EventHandler<InPlaceVisibilityChangeEventArgs>(tip_InPlaceVisibilityChanging);

第二个示例定义 InPlaceVisibilityChanging 事件的事件处理程序，其中 Visible 值用于设置 TextBox (outputTextBox) 的 TextBox.Text 属性。

Sub tip_InPlaceVisibilityChanging(ByVal sender As Object, ByVal e As InPlaceVisibilityChangeEventArgs)
    outputTextBox.Text += IIf(e.Visible, "Panel is Visible", "Panel is not Visible") + Environment.NewLine
End Sub

void tip_InPlaceVisibilityChanging(object sender, InPlaceVisibilityChangeEventArgs e)
{
    outputTextBox.Text += (e.Visible ? "Panel is Visible" : "Panel is not Visible") + Environment.NewLine;
}
