Loot event?

[DeadlyAppearance]

Hi, i`m new to ui programming.
I have done a quick tutorial to understand how it works.
Now i have the first question. I found the function GetLootSlotInfo() which i want to use.
I think i must call my own function in the <OnEvent> tag in the xml file.
Now i must set the event with RegisterEvent. But what is the right event? I haven`t found a eventlist.
Or this this the wrong way to do something if the lootwindow open?

I hope someone can help me to understand how this works.

Try that. That is also a list of all the known events.
