带边框的透明窗口(Transparent window with a border)

带边框的透明窗口(Transparent window with a border)

我试图制作一个小截图程序，我正在制作一个带边框的小型WPF窗口。 这应该作为“视口”，因此窗口内（边框内）的所有内容都应该是截图。 然而，当我将窗口的透明度设置为0然后我看不到我的边框时。 有关如何使我的网格完全透明，并仍然保留2 xx黑色边框的任何想法？

Im trying to make a small screenshot program, im making a small WPF window with a border. This should function as a "Viewport" so everything inside the window (within the border) should be screenshottet. How ever when i set the transparency of the window to 0 then i cant see my border. Any ideas on how to make my grid fully transparent, and still preserve a 2 px black border around it?

不确定您是希望窗口还是只有网格透明边框。

这会在窗口周围绘制边框：

<Window x:Class="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" AllowsTransparency="True" WindowStyle="None" Background="Transparent" BorderThickness="2" BorderBrush="Black"> <Grid> </Grid> </Window>

这只是在网格周围绘制一个broder：

<Window x:Class="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" AllowsTransparency="True" WindowStyle="None" Background="Transparent"> <Border BorderThickness="2" BorderBrush="Black"> <Grid> </Grid> </Border> </Window>

Not sure if you want the window or just the grid transparent with border.

That draws a border around the window:

<Window x:Class="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" AllowsTransparency="True" WindowStyle="None" Background="Transparent" BorderThickness="2" BorderBrush="Black"> <Grid> </Grid> </Window>

This is drawing a broder around the grid only:

<Window x:Class="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" AllowsTransparency="True" WindowStyle="None" Background="Transparent"> <Border BorderThickness="2" BorderBrush="Black"> <Grid> </Grid> </Border> </Window>
