在TextEditor裏下斷點，得到如下堆棧：
1 TextEditor::TextDocument::plainText
2 CppEditor::Internal::CppEditorDocument::contentsText
3 CppEditor::Internal::CppEditorDocumentHandleImpl::contents
4 CppTools::CppModelManager::buildWorkingCopyList

51級堆棧纔到達我們的斷點。可以看到調用軌跡，TextEditor會調用CppEditor,後者又會回調前者。我感覺qt-creator模塊設計得不錯，以後可擴充至任何語言。
