e.g. in my UMG, there’s ScrollBox contains message list, and I need to store MsgID in very UButton Widget(a UButton represents a message), because I want to get MsgID from UButton Widget Object in callback function of UButton.
I appreciate the feedback but I don’t think I’ll be adding this. In order for you to store MsgID, MsgID would need to be a UObject. You should instead make the buttons in the list a common UserWidget with members holding the information you care about, with the ability to handle being clicked internally rather than trying to just hang data onto primitive controls. That would encapsulate the responsibility and data for each item.
OK, I see. Your suggestion is better, thx very much~
