UListView - barsandcat/HMS-Sunflower GitHub Wiki

Has siblings:

• UListView
• UTreeView
• UTileView

Actually just a wrapper of SListView that does all of that in one class

Dynamically constructs widgets as needed during scroll

• Needs a widget class to create
• Use object list source of data - its up to you to do something sensible in your list entry widget with list data

Has selection support

• None
• Singe
• Multiple (including range selection and adding to selection)

Manages list of selected items even between data updates

Handles input:

• Buttons navigation
• Mouse click into list background to clear selection

List entries must implement IUserObjectListEntry

• It has GetOwningListView
• Has extension point IsListItemSelectable and events OnItemSelectionChanged - and it is is used in SObjectTableRow - which is something new to me

List entries are wrapped up in SObjectTableRow. UCommonListView requires entry to be descendant of UCommonButtonBase to be able to handle clicks, and has its own wrapper SCommonButtonTableRow
