STedsTableViewer

A table viewer widget can be used to show a visual representation of data in TEDS.

API > API/Plugins > API/Plugins/TedsTableViewer

A table viewer widget can be used to show a visual representation of data in TEDS. The rows to display can be specified using a RowQueryStack, and the columns to display are directly input into the widget Example usage:

SNew(STedsTableViewer) .QueryStack(MakeShared(&Rows)) .Columns({FTypedElementLabelColumn::StaticStruct(), FTypedElementClassTypeInfoColumn::StaticStruct());
