Question

我有来自TForm的后代的自定义表单。我使用ToolApi注册自定义模块并将其添加到存储库。到现在为止还挺好。但是当我点击File-＆gt; New时，我可以看到我的自定义表单的图标类别，但它被禁用了。图标是灰色的，我无法从菜单中选择它来创建自定义表单并将其添加到项目中。

您有什么建议和提示有什么不对吗？我应该尝试什么？

完整的存储库向导（带有自定义表单）在Bruno Fierens的白皮书中进行了演示，您可以从此处获取：http://forms.embarcadero.com/forms/AMUSCA1104BrunoFierensOTAPIWhitepaper通过Embarcadero。

我给你链接而不仅仅是答案的原因是我注意到你的代码不止一个问题，你将从阅读白皮书中受益！它不会花费你很长时间，演示应用程序随之而来，它不仅解决了这个问题，而且在玩OTAPI时可能遇到的大多数问题。

使用ToolsApi在delphi 2010中注册自定义表单
