If container is minimized

Hi,

I need to know if the container is minimized or not. The container structure dont show it.

Code:

---

{itemcount = 2, itemid = 2854, isopen = true, ispage = false, hashigher = true, item = {{count = 1, special = 0, id = 3505}, {count = 1, special = 0, id = 2872}}, name = "Backpack", maxcount = 20}
