我的应用程序中有一些源自共同祖先的表单，例如：
TAtFormBaseIW = class( TIWAppForm )
和
TAtFormExplorerIW = class( TAtFormBaseIW )
这适用于某些表单，但不适用于其他表单。
让我大胆猜测一下：它似乎适用于 IW 10 之前在 Delphi 中创建的所有表单，但不适用于我使用 IW 10 创建的表单。较新的表单会发生什么情况：HWenever 我想将它们加载到 IDE 中，它们被解释为 win32 表单，一些属性被忽略（所有典型的 win32 属性，例如 ClientWidth），并且我被告知不能将 IW 组件放在这些表单上。
使它们成为 TIWAppForm 的直接后代，保存它们并使用普通的文本编辑器将它们改回原样。重新编译后，它们在浏览器中显示得很好，但在 IDE 中却显示不出来。
知道发生了什么吗？
I have forms in my application that I derive from a common ancestor, like:
TAtFormBaseIW = class( TIWAppForm )
and
TAtFormExplorerIW = class( TAtFormBaseIW )
This works for certain forms, but not for others.
Let me make a wild guess: it seems to work for all forms that where created in Delphi prior to IW 10, but not for forms I created with IW 10. What happens with newer forms: HWenever I want to load them into the IDE, they are interpreted as win32 forms, some properties are ignored (all typical win32 properties such as ClientWidth), and I am told that I cannot put IW components on these forms.
Making them direct descendants of TIWAppForm, saving them and using a normal text editor to change them back works. After a recompile they show up fine in the browser, but never in the IDE.
Any idea of what is happening?

我犯了罪，我犯了最大的罪。这个问题与 IntraWeb 无关，而是与将派生表单添加到项目中的方式有关。
在向项目添加新表单后，我不应该只是将 TIWAppForm 更改为 TAtFormBaseIW，而是应该执行以下操作：
在 IDE
文件/新建/其他/可继承项
中选择，然后选择要从中派生表单的基本表单。
如果要将现有表单转换为派生形式，还可以将 dfm 文件中的前导关键字 object 更改为 inherited。

Mea culpa, mea maxima culpa. This problem has nothing to do with IntraWeb, but with the way a derived form should be added to the project.
Instead of just changing TIWAppForm to TAtFormBaseIW, after having added a new form to the project, I should do this:
Select in the IDE
File / New / Other / Inheritable Items
and then the base form you want to derive your form from.
If you want to turn an existing form into a derivate, also change the leading key word object in the dfm file to inherited.
