关键摘要:

• 在ConnectWidget::initUI()函数中，新增的QSpacerItem可能会导致布局问题，需要确认是否与现有布局策略兼容。
• 在ConnectWidget::initConnectLayout()函数中，新增的ipVLayout->addSpacing(14);可能会影响布局美观，应确保这一改动不会破坏现有的布局结构。
• 检查是否有必要在mainLayout和ipVLayout中使用QSpacerItem，如果布局已经足够灵活，则可能不需要添加额外的空白空间。

是否建议立即修改:

• 是，需要确保布局的改动不会影响用户界面的美观性和功能正确性。如果新增的空白空间会导致布局问题，应立即进行修正。
