我有一個專案，它由許多不同的框架組成。其中一些框架是相互繼承的。這是基本設定：
- TBaseFrame
- TFrame1
- TFrame1A
- TFrame1B
- TFrame2
- TFrame2A
- TFrame1
...等等。
一切都很好，花花公子。我已經能夠整天用這個設定編譯和運行我的專案。但是，在某些時候，它開始完全失敗并崩潰。
在應用程式啟動時，在主螢屏顯示后不久，我收到此錯誤：
奇怪的是，我的應用程式中還沒有創建或使用任何這些框架——這些框架位于一個僅在登錄后才顯式創建的表單上（我確認它不是自動創建的）。
按 OK 后，我的應用程式將終止，然后顯示此錯誤：
After some digging, I discovered something very odd in the IDE. I closed Delphi and re-opened it, and I'm still seeing this discrepancy.
On the base frame (TBaseFrame), it does not show any ClientWidth or ClientHeight properties:
However the inherited frame (TFrame1) does:
It seems as if the inherited frame is being treated as if it's a form, especially seeing a Caption property there which shouldn't belong.
Why did this happen and how do I fix it?
EDIT
To add, when I go to my project options, it's offering me to add many of the frames to auto-create, which should not be possible. And in fact one of the frames (the most recently created one) is already set to auto-create. But it's a frame, not a form.
EDIT 2
After finding and removing the 1 frame from the project's auto-create, as well as removing another (unrelated) frame which had class name conflicts and re-adding it to the project, now I'm able to at least compile the project and run it. Yet still numerous frames appear as if they're forms.
uj5u.com熱心網友回復：
您在使用某些 Delphi 版本的 IDE 設計器時遇到問題，它忘記了繼承的框架是框架。
要解決此問題，請打開專案源并在受影響框架的組件名稱后添加“：TFrame”。保存、關閉并重新打開專案。
這是一個示例：
MyFrame1 in 'MyFrame1.pas' {Frame1: TFrame};
