一个跨平台的`ChatGPT`悬浮窗工具

一个跨平台的ChatGPT悬浮窗工具

使用avalonia实现的ChatGPT的工具，设计成悬浮窗，并且支持插件。

如何实现悬浮窗？

在使用avalonia实现悬浮窗也是非常的简单的。

实现我们需要将窗体设置成无边框

在Window根节点添加一下属性，想要在Linux下生效请务必添加SystemDecorations属性

ExtendClientAreaToDecorationsHint="True"
ExtendClientAreaChromeHints="NoChrome"
ExtendClientAreaTitleBarHeightHint="-1"
SystemDecorations="None"

这样我们的窗口就设置成了无边框。

然后我们还需要将窗体的大小固定，

Height="50"
MaxHeight="50"
Width="{Binding Width}"
MaxWidth="{Binding Width}"

高度固定，宽度绑定到ViewModel的Width属性中，默认270，

接下来给出所有代码，

只需要设置无边框并且固定大小。悬浮窗的效果就达到了。

我们看看执行效果

就这样简单的悬浮窗写好了，我们使用一下悬浮窗的搜索功能

这个就是简单的使用效果，对比其他的工具，这个悬浮窗更简洁，并且跨平台和开源。

目前的项目结构。

plugin下面的项目是默认的插件，用于搜索系统文件（未完善）

Gotrays.Suspension.Client则是实际的客户端。

Gotrays.Suspension.PlugIn则是插件定义的接口规范。

Gotrays.Update则是检查更新程序，用于更新主程序。

实现插件

plug-in

插件模块，用于扩展功能。

插件开发

1. 创建插件项目

在解决方案中创建一个类库项目，项目名称以Gotrays.Suspension.PlugIn.开头，例如Gotrays.Suspension.PlugIn.Test。

然后在项目中依赖Gotrays.Suspension.PlugIn类库。

2. 创建插件类

在项目中创建一个类，继承Gotrays.Suspension.PlugIn.PlugInBase类，例如：

using Gotrays.Suspension.PlugIn;

public class SystemTools : PlugInBase
{
    public SystemTools()
    {
        Name = "系统搜索";

​        // 获取system.png嵌入资源的Stream
​        var stream = GetType().Assembly.GetManifestResourceStream("SystemTools.system.png");
​        if (stream == null) return;

工具服务会进行自动发现，无需手动注册。

只需要将程序集放置在./plug-in目录下即可。

服务会在一个程序集中发现所有的插件类，并且进行注册。

按照上面的方式非常的简单就集成了插件。
