Open a small floating window at cursor position
提问by JanivZ
I'm writing a small proof of concept that requires me to listen to some key combination that when pressed opens a small WPF/WinFormswindow underneath the current cursor position. I'm more of a web guy so I'm having trouble starting with this.
我正在编写一个小的概念证明，需要我听一些组合键，当按下该组合键时WPF/WinForms，会在当前光标位置下方打开一个小窗口。我更像是一个网络人，所以我在开始时遇到了麻烦。
Can anyone point me in the right direction? Or provide some resources/examples?
任何人都可以指出我正确的方向吗？或者提供一些资源/例子？
Thanks.
谢谢。

Try this example for WPF. By pressing the Enterkey displays a Popupwindow in advance receiving the coordinates of the mouse cursor.
试试这个 WPF 的例子。通过Enter按键显示一个Popup窗口，预先接收鼠标光标的坐标。
XAML
XAML
<Window x:Class="OpenWindowForCursor.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525"
WindowStartupLocation="CenterScreen"
PreviewKeyDown="Window_PreviewKeyDown">
<Grid>
<Popup Name="PopupWindow"
Placement="Relative"
IsOpen="False"
StaysOpen="False">
<Border Width="100"
Height="100"
Background="AntiqueWhite">
<Label Content="Test" />
</Border>
</Popup>
</Grid>
</Window>
Code-behind
Code-behind
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Window_PreviewKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
PopupWindow.IsOpen = true;
var point = Mouse.GetPosition(Application.Current.MainWindow);
PopupWindow.HorizontalOffset = point.X;
PopupWindow.VerticalOffset = point.Y;
}
}
}
Edit: An easier solution

You can just set Placement="Mouse"for Popupinstead receive coordinates of the mouse:
您可以只设置Placement="Mouse"forPopup而不是接收鼠标的坐标：
XAML
XAML
<Grid>
<Popup Name="PopupWindow"
Placement="Mouse"
IsOpen="False"
StaysOpen="False">
<Border Width="100"
Height="100"
Background="AntiqueWhite">
<Label Content="Test" />
</Border>
</Popup>
</Grid>
Code-behind
Code-behind
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Window_PreviewKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
PopupWindow.IsOpen = true;
}
}
}
