Member Function Documentation

◆ Construct()

void SDragAndDropVerticalBox::Construct ( const FArguments & InArgs )

Handle this event to determine whether a drag and drop operation can be executed on top of the target row widget. Most commonly, this is used for previewing re-ordering and re-organization operations in lists or trees. e.g. A user is dragging one item into a different spot in the list or tree. This delegate will be called to figure out if we should give visual feedback on whether an item will successfully drop into the list. Perform a drop operation onto the target row widget Most commonly used for executing a re-ordering and re-organization operations in lists or trees. e.g. A user was dragging one item into a different spot in the list; they just dropped it. This is our chance to handle the drop by reordering items and calling for a list refresh.

◆ OnDragDetected()

FReply SDragAndDropVerticalBox::OnDragDetected	(	const FGeometry &	MyGeometry,
		const FPointerEvent &	MouseEvent
	)

overridevirtual

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 SWidget.

◆ OnDragEnter()

void SDragAndDropVerticalBox::OnDragEnter	(	FGeometry const &	MyGeometry,
		FDragDropEvent const &	DragDropEvent
	)

overridevirtual

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 SWidget.

◆ OnDragLeave()

void SDragAndDropVerticalBox::OnDragLeave ( FDragDropEvent const & DragDropEvent )

overridevirtual

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

Parameters

DragDropEvent The drag and drop event.

Reimplemented from SWidget.

◆ OnDragOver()

FReply SDragAndDropVerticalBox::OnDragOver	(	const FGeometry &	MyGeometry,
		const FDragDropEvent &	DragDropEvent
	)

overridevirtual

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.

Reimplemented from SWidget.

◆ OnDrop()

FReply SDragAndDropVerticalBox::OnDrop	(	const FGeometry &	MyGeometry,
		const FDragDropEvent &	DragDropEvent
	)

overridevirtual

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 SWidget.

◆ OnMouseButtonDown()

FReply SDragAndDropVerticalBox::OnMouseButtonDown	(	const FGeometry &	MyGeometry,
		const FPointerEvent &	MouseEvent
	)

overridevirtual

Drag detection and handling

Reimplemented from SWidget.

◆ OnPaint()

int32 SDragAndDropVerticalBox::OnPaint	(	const FPaintArgs &	Args,
		const FGeometry &	AllottedGeometry,
		const FSlateRect &	MyCullingRect,
		FSlateWindowElementList &	OutDrawElements,
		int32	LayerId,
		const FWidgetStyle &	InWidgetStyle,
		bool	bParentEnabled
	)		const

overridevirtual

The widget should respond by populating the OutDrawElements array with FDrawElements that represent it and any of its children. Called by the non-virtual OnPaint to enforce pre/post conditions during OnPaint.

Parameters

Args	All the arguments necessary to paint this widget (
AllottedGeometry	The FGeometry that describes an area in which the widget should appear.
MyCullingRect	The rectangle representing the bounds currently being used to completely cull widgets. Unless IsChildWidgetCulled(...) returns true, you should paint the widget.
OutDrawElements	A list of FDrawElements to populate with the output.
LayerId	The Layer onto which this widget should be rendered.
InColorAndOpacity	Color and Opacity to be applied to all the descendants of the widget being painted
bParentEnabled	True if the parent of this widget is enabled.

Returns: The maximum layer ID attained by this widget or any of its children.

Reimplemented from SPanel.
