在不知道什么版本的UE推出的ToolMenus模块，这个模块主要工作就是像它的名字一样，用来创建和管理编辑器菜单的工具。在此之前UE编辑器的扩展方式需要先加载想添加的模块，在找到对应的变量或函数进行修改。而ToolMenus的出现就是为了简化这一流程，
关于UToolMenus的开发与样例代码网上已经有非常多了，此处不再赘述。
因官方没有提供ToolMenus的扩展路径，所以这里我们需要自己来获取：
原理通过反射将初始化过的所有菜单都保存到文件中：
static void PrintAllMenus()
{
FMapProperty* MapProp = FindFProperty<FMapProperty>(UToolMenus::StaticClass(), FName("Menus"));
TMap<FName, TObjectPtr<UToolMenu>>* MapValuePtr = MapProp->ContainerPtrToValuePtr<TMap<FName, TObjectPtr<UToolMenu>>>(UToolMenus::Get());
TArray<FName> Out;
MapValuePtr->GetKeys(Out);
Out.Sort();
FString Str;
for (auto Item : Out)
{
Str += Item.ToString();
Str += TEXT('\n');
}
FFileHelper::SaveStringToFile(Str, TEXT("D:/a.txt"));
}
这里简单列举几个比较常用的路径
AssetEditor.AnimationEditor.ToolBar 动画编辑器工具栏 AssetEditor.BlueprintEditor.ToolBar 蓝图编辑器工具栏 AssetEditor.MaterialEditor.ToolBar 材质编辑器工具栏 AssetEditor.SkeletalMeshEditor.ToolBar 骨骼网格体编辑器工具栏 AssetEditor.SkeletonEditor.ToolBar 骨骼编辑器工具栏 AssetEditor.StaticMeshEditor.ToolBar 网格编辑器工具栏 ContentBrowser.ToolBar 内容浏览器工具栏 LevelEditor.LevelEditorToolBar 关卡编辑器工具栏 LevelEditor.MainMenu 关卡编辑器主菜单
更多但也不是全部的路径：
