背水一战 Windows 10 (36) - 控件(弹出类): ToolTip, Popup, PopupMenu



作者:webabcd


介绍
背水一战 Windows 10 之 控件(弹出类)

  • ToolTip
  • Popup
  • PopupMenu



示例
1、ToolTip 的示例
Controls/FlyoutControl/ToolTipDemo.xaml

<Page
    x:Class="Windows10.Controls.FlyoutControl.ToolTipDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.Controls.FlyoutControl"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="10 0 10 10">

            <!--
                ToolTip - 提示框控件
                    Content - 提示内容
                    Placement - 提示框的显示位置(Bottom, Right, Mouse, Left, Top)
                    HorizontalOffset - 水平偏移量
                    VerticalOffset - 垂直偏移量
                    IsOpen - 提示框是否是显示状态(如果要设置此属性的话,需要等到宿主加载完之后再设置)
                    Closed - 提示框关闭后触发的事件
                    Opened - 提示框打开后触发的事件

                注:我这里测试 ToolTip 的最大宽度是 320
            -->

            <TextBlock Name="textBlock1" Text="TextBlock" Margin="5"
                       ToolTipService.ToolTip="ToolTip 的内容" 
                       ToolTipService.Placement="Right" />
