Detailed Description

template<typename ItemType>
class SObjectTableRow< ItemType >

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

By using UUserWidget::TakeDerivedWidget<T>(), 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 IUserListEntry UInterface, which allows the row widget to respond to various list-related events.

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

◆ OnDragCancelled()

template<typename ItemType >

void SObjectTableRow< ItemType >::OnDragCancelled	(	const FDragDropEvent &	DragDropEvent,
		UDragDropOperation *	Operation
	)

inlineoverridevirtual

Reimplemented from SObjectWidget.

◆ OnDragDetected()

template<typename ItemType >

virtual FReply SObjectTableRow< ItemType >::OnDragDetected	(	const FGeometry &	MyGeometry,
		const FPointerEvent &	MouseEvent
	)

inlineoverridevirtual

Called when Slate detects that a widget started to be dragged. Usage: A widget can ask Slate to detect a drag. OnMouseDown() reply with FReply::Handled().DetectDrag( SharedThis(this) ). Slate will either send an OnDragDetected() event or do nothing. If the user releases a mouse button or leaves the widget before a drag is triggered (maybe user started at the very edge) then no event will be sent.

Parameters

InMyGeometry	Widget geometry
InMouseEvent	MouseMove that triggered the drag

Reimplemented from SObjectWidget.

◆ OnDragEnter()

template<typename ItemType >

virtual void SObjectTableRow< ItemType >::OnDragEnter	(	const FGeometry &	MyGeometry,
		const FDragDropEvent &	DragDropEvent
	)

inlineoverridevirtual

Called during drag and drop when the drag enters a widget.

Enter/Leave events in slate are meant as lightweight notifications. So we do not want to capture mouse or set focus in response to these. However, OnDragEnter must also support external APIs (e.g. OLE Drag/Drop) Those require that we let them know whether we can handle the content being dragged OnDragEnter.

The concession is to return a can_handled/cannot_handle boolean rather than a full FReply.

Parameters

MyGeometry	The geometry of the widget receiving the event.
DragDropEvent	The drag and drop event.

Returns: A reply that indicated whether the contents of the DragDropEvent can potentially be processed by this widget.

Reimplemented from SObjectWidget.

◆ OnDragLeave()

template<typename ItemType >

virtual void SObjectTableRow< ItemType >::OnDragLeave ( FDragDropEvent const & DragDropEvent )

inlineoverridevirtual

Called during drag and drop when the drag leaves a widget.

Parameters

DragDropEvent The drag and drop event.

Reimplemented from SObjectWidget.

◆ OnDragOver()

template<typename ItemType >

virtual FReply SObjectTableRow< ItemType >::OnDragOver	(	const FGeometry &	MyGeometry,
		const FDragDropEvent &	DragDropEvent
	)

inlineoverridevirtual

Called during drag and drop when the the mouse is being dragged over a widget.

Parameters

MyGeometry	The geometry of the widget receiving the event.
DragDropEvent	The drag and drop event.

Returns: A reply that indicated whether this event was handled.

◆ OnDrop()

template<typename ItemType >

virtual FReply SObjectTableRow< ItemType >::OnDrop	(	const FGeometry &	MyGeometry,
		const FDragDropEvent &	DragDropEvent
	)

inlineoverridevirtual

Called when the user is dropping something onto a widget; terminates drag and drop.

Parameters

MyGeometry	The geometry of the widget receiving the event.
DragDropEvent	The drag and drop event.

Returns: A reply that indicated whether this event was handled.

Reimplemented from SObjectWidget.
