Reviewer's Guide by Sourcery

This pull request optimizes the DelegateModel refresh process by only updating the visibility of items that have changed, rather than refreshing all items. This is achieved by tracking visible and invisible items and updating their group membership accordingly. The update function was also modified to only move items in the visibleItems group if their visibleIndex has changed.

No diagrams generated as the changes look simple and do not need a visual representation.

关键摘要:

• 在update函数中，i变量在循环外部被重新声明，可能导致作用域问题。
• items.removeGroups和items.addGroups方法的使用可能不正确，需要确认这些方法是否接受相同的参数。
• item.inVisible属性在代码中被注释掉了，如果这个属性不再使用，应该移除以避免混淆。

是否建议立即修改:

• 是

• unVisible数组在update函数中被声明，但在函数外部没有使用，可能是不必要的。
• items.removeGroups和items.addGroups方法的使用可能需要确认是否正确处理了所有可能的边界情况，例如当items为空时。
