Classes

  Type Name Description
Public class FDraggableBoxUIDragOperation A drag/drop operation used by SDraggableBox, largely modeled on FInViewportUIDragOperation, except instead of requiring the drop location to be able to handle that particular class to trigger the OnDragComplete delegate, it just triggers on any drop.  
Public struct ModelingUIConstants Constants used for various standard ModelingUI gizmos/etc  
Public class SComboPanel SComboPanel provides a ComboBox-type interface but instead of a drop-down list, a STileView panel ("Flyout") is shown with an icon for each selectable item.  
Public class SDraggableBox A widget for the draggable box itself, which requires its parent to handle its positioning in response to the drag.  
Public class SDraggableBoxOverlay Class that can be used to place a draggable box into a viewport or some other large widget as an overlay.  
Public class SDynamicNumericEntry SNumericEntryBox wrapper that supports custom Get/SetValue and dynamic value/UI range  
Public class STickDelegateWidget Simple widget that calls its OnTickDelegate in its Tick function, to allow for custom tick behavior via composition instead of having to create a class and override the method, for instance when creating custom slate in-line somewhere.  
Public class SToolInputAssetComboPanel SToolInputAssetComboPanel provides a similar UI to SComboPanel but specifically for picking Assets.  
Public class SToolInputAssetPicker SToolInputAssetPicker is designed to support Asset picking in Modeling Tools, where the Assets in question are input parameters/options to Tools, eg such as a brush alpha texture for use in a Painting/Sculpting Tool.
