Syntax

template<typename ItemType>  
class SObjectTableRow :  
    public SObjectWidget,  
    public IObjectTableRow

Remarks

It's an SObjectWidget! It's an ITableRow! It does it all!

By using UUserWidget::TakeDerivedWidget(), this class allows UMG to fully leverage the robust Slate list view widgets. The major gain from this is item virtualization, which is an even bigger deal when unnecessary widgets come with a boatload of additional UObject allocations.

The owning UUserWidget is expected to implement the IUserListItem UInterface, which allows the row widget to respond to various list-related events.

Note: Much of the implementation here matches STableRow exactly, so refer there if looking for additional information.
