关键摘要:

• 在TabWidgetPrivate::createEditor函数中，增加了对doc参数的检查和处理，确保在打开文件时提供正确的文档。
• TextEditor::openFileWithDocument函数被重命名为openFile，以符合现有的命名约定。
• TextEditor::openFile函数增加了对文件打开时文档参数的检查，确保文档正确传递。
• TextEditor::save函数中移除了对fileSaved信号的发射，因为这可能导致循环发送信号。
• TextEditor::reload函数中移除了对fileSaved信号的发射，因为这可能导致循环发送信号。
• TextEditor::addBreakpoint、TextEditor::findUsage和TextEditor::renameSymbol函数中移除了对fileSaved信号的发射，因为这可能导致循环发送信号。
• WorkspaceWidgetPrivate::doSplit函数中增加了对fromTW参数的检查，确保来源的TabWidget存在。
• WorkspaceWidgetPrivate::onSplitRequested函数中，将doSplit函数的参数从spliter, index, fileName, cursorPos, scroll更改为tabWidgetSender, spliter, index, fileName，以匹配新的doSplit函数签名。

是否建议立即修改:
是

这些修改主要是为了修复潜在的循环信号发送问题，确保信号只在适当的时候被发送，避免可能的性能问题和逻辑错误。此外，这些修改也提高了代码的可读性和一致性，符合Qt和整个项目中的命名约定。
