在VS 2017自定义项目系统中，如何在解决方案资源管理器中使项目项加粗?

Question

我正在为 VS 2017 编写一个项目系统扩展，每个项目用我的语言都有一个文件，即"启动文件"。我希望该文件在解决方案资源管理器中显示为粗体。

Python Tools for VS做了我想要的，但我的扩展建立在新的项目系统框架(CPS(上。更改解决方案资源管理器项外观的 CPS 方法是实现IProjectTreePropertiesProvider，但我看不到任何使用它更改文本样式的方法——只有图标。

我不确定CPS是否为此内置了任何东西，但是您仍然可以混合使用"旧"本机/托管Visual Studio界面。下面是一个使用 IProjectTreePropertiesProvider 的示例：

[Export(typeof(IProjectTreePropertiesProvider))]
[AppliesTo(MyUnconfiguredProject.UniqueCapability)]
[Order(1000)]
internal class ProjectTreePropertiesProvider1 : IProjectTreePropertiesProvider
{
// we need to import that to do COM calls
[Import]
protected IProjectThreadingService ThreadingService { get; set; }
// we want the "old" IVsHierarchy interface 
[ImportMany(ExportContractNames.VsTypes.IVsHierarchy)]
private OrderPrecedenceImportCollection<IVsHierarchy> IVsHierarchies { get; }
private IVsHierarchy VsHierarchy => IVsHierarchies.First().Value;
[ImportingConstructor]
public ProjectTreePropertiesProvider1(UnconfiguredProject unconfiguredProject)
{
IVsHierarchies = new OrderPrecedenceImportCollection<IVsHierarchy>(projectCapabilityCheckProvider: unconfiguredProject);
}
/// <summary>
/// Calculates new property values for each node in the project tree.
/// </summary>
/// <param name="propertyContext">Context information that can be used for the calculation.</param>
/// <param name="propertyValues">Values calculated so far for the current node by lower priority tree properties providers.</param>
public async void CalculatePropertyValues(IProjectTreeCustomizablePropertyContext propertyContext, IProjectTreeCustomizablePropertyValues propertyValues)
{
// this is from the standard WindowsScript project type sample
if (propertyValues.Flags.Contains(ProjectTreeFlags.Common.ProjectRoot))
{
// etc..
propertyValues.Icon = KnownMonikers.JSProjectNode.ToProjectSystemType();
// etc..
}
// now, we're doing some COM calls, ensure it happens on UI thread
await ThreadingService.SwitchToUIThread();
// get the id of some item (this "Start.js" item is from the standard sample)
VsHierarchy.ParseCanonicalName("Start.js", out uint id);
// get IVsUIShell from service provider
VsHierarchy.GetSite(out Microsoft.VisualStudio.OLE.Interop.IServiceProvider sp);
var shell = (IVsUIShell)sp.QueryService<IVsUIShell>();
// get solution explorer's window
var SolutionExplorer = new Guid(ToolWindowGuids80.SolutionExplorer);
shell.FindToolWindow(0, ref SolutionExplorer, out IVsWindowFrame frame);
// get solution explorer's DocView
frame.GetProperty((int)__VSFPROPID.VSFPROPID_DocView, out object obj);
var window = (IVsUIHierarchyWindow2)obj;
// change attribute of the item
window.SetItemAttribute((IVsUIHierarchy)VsHierarchy, id, (uint)__VSHIERITEMATTRIBUTE.VSHIERITEMATTRIBUTE_Bold, true);
}
}
