[翻译]  How to create a WPF Window without a border that can be resized?

[CHINESE]  如何创建一个没有可以调整大小的边框的WPF窗口?


Is there a way in WPF where I can remove the main window's border, yet allow that window to be resized (without grip)?

在WPF中有没有办法可以删除主窗口的边框,但允许调整窗口大小(没有夹点)?

I realized there's a way to do this scenario by setting resize mode to CanResizeWithGrip. However, I want to be able to do it with the resize mode set to CanResize.

我意识到有一种方法可以通过将调整大小模式设置为CanResizeWithGrip来完成此方案。但是,我希望能够将调整大小模式设置为CanResize。

I tried setting the following:

我尝试设置以下内容:

ResizeMode="CanResize" 
WindowStyle="None"
AllowsTransparency="True"

However, by setting AllowsTransparency, it removes the ability to resize without the grip. Any ideas how I can pull this off?

但是,通过设置allowsTransparency,它将删除没有夹点时调整大小的功能。我有什么想法可以解决这个问题吗?

I also should note that I can't set AllowsTransparency to true anyway, because I am using a winformshost control in my window, which is not shown when AllowsTransparency is true.

我还应该注意,无论如何我都不能将AllowTransparency设置为true,因为我在我的窗口中使用了winformshost控件,当AllowTransparency为true时,它不显示。

The user needs something to interact with to resize the window. If you don't like the default border or grip, you'll need to add some other control with a click and drag behavior that resizes the window. Perhaps a line on each edge of the window?

用户需要与之交互以调整窗口大小。如果您不喜欢默认边框或夹点,则需要添加一些其他控件,其中包含调整窗口大小的单击和拖动行为。也许在窗口的每个边缘都有一条线?

You can use the WPF customizable window library, available here: http://wpfwindow.codeplex.com/

您可以使用WPF自定义窗口库,可在此处获取:http://wpfwindow.codeplex.com/

Then, when using the library's window type, you can set the same properties as you listed above

然后,使用库的窗口类型时,可以设置与上面列出的属性相同的属性

<CustomWindow:EssentialWindow x:Class="CustomWindowDemo.DemoEssentialWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:CustomWindow="clr-namespace:CustomWindow;assembly=CustomWindow"
    AllowsTransparency="True" ResizeMode="CanResize" WindowStyle="None" Title="EssentialWindow"
    Height="300" Width="250">

This can happen if ResizeBorderThickness is set to 0.

如果ResizeBorderThickness设置为0,则会发生这种情况。

It can be set to a positive value in XAML like this:

它可以在XAML中设置为正值,如下所示:

<WindowChrome>
    <WindowChrome.ResizeBorderThickness>
        <Thickness>1</Thickness>
    </WindowChrome.ResizeBorderThickness>
</WindowChrome>

The simplest, but maybe too simple is

最简单的,但也许太简单了

this.MouseLeftButtonDown += delegate { this.DragMove(); };
