我有点。我想在Point附近显示Popup。有什么属性可以设置它吗?我在这里发现了类似的问题,但它们不是我想要的
下面是一个例子。当你在一个窗口上点击鼠标时,弹出窗口将被移动:
XAML:
<Window x:Class="WpfApplication60.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="myWindow"
Title="MainWindow" Height="350" Width="525" MouseLeftButtonDown="Window_MouseLeftButtonDown">
<Grid>
<Popup x:Name="myPopup" PlacementTarget="{Binding ElementName=myWindow}" Placement="Relative">
<Label Width="50" Height="20" Background="LightGreen" MouseLeftButtonDown="Label_MouseLeftButtonDown">I am the Popup</Label>
</Popup>
</Grid>
</Window>
代码:
private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
Point current = e.GetPosition(this);
myPopup.HorizontalOffset = current.X;
myPopup.VerticalOffset = current.Y;
myPopup.IsOpen = true;
}
