Detailed Description

Implements a widget switcher.

A widget switcher is like a tab control, but without tabs. At most one widget is visible at time.

Member Typedef Documentation

◆ FScopedWidgetSlotArguments

using SWidgetSwitcher::FScopedWidgetSlotArguments = TPanelChildren<FSlot>::FScopedWidgetSlotArguments

◆ FSlot

using SWidgetSwitcher::FSlot = FBasicLayoutWidgetSlot

Constructor & Destructor Documentation

◆ SWidgetSwitcher()

SWidgetSwitcher::SWidgetSwitcher ( )

Holds the index of the initial widget to be displayed (INDEX_NONE = default).

◆ ~SWidgetSwitcher()

SWidgetSwitcher::~SWidgetSwitcher ( )

virtualdefault

Member Function Documentation

◆ AddSlot()

SWidgetSwitcher::FScopedWidgetSlotArguments SWidgetSwitcher::AddSlot ( int32 SlotIndex = INDEX_NONE )

Adds a slot to the widget switcher at the specified location.

Parameters

SlotIndex The index at which to insert the slot, or INDEX_NONE to append.

◆ ComputeDesiredSize()

FVector2D SWidgetSwitcher::ComputeDesiredSize ( float ) const

overrideprotectedvirtual

A Panel's desired size in the space required to arrange of its children on the screen while respecting all of the children's desired sizes and any layout-related options specified by the user. See StackPanel for an example.

Returns: The desired size.

Implements SPanel.

◆ ComputeVolatility()

virtual bool SWidgetSwitcher::ComputeVolatility ( ) const

inlineoverrideprotectedvirtual

Recomputes the volatility of the widget. If you have additional state you automatically want to make the widget volatile, you should sample that information here.

Reimplemented from SWidget.

◆ Construct()

void SWidgetSwitcher::Construct ( const FArguments & InArgs )

Constructs the widget.

◆ GetActiveSlot()

const SWidgetSwitcher::FSlot * SWidgetSwitcher::GetActiveSlot ( ) const

protected

◆ GetActiveWidget()

TSharedPtr< SWidget > SWidgetSwitcher::GetActiveWidget ( ) const

Gets the active widget.

Returns: Active widget.

◆ GetActiveWidgetIndex()

int32 SWidgetSwitcher::GetActiveWidgetIndex ( ) const

inline

Gets the slot index of the currently active widget.

Returns: The slot index, or INDEX_NONE if no widget is active.

◆ GetChildren()

FChildren * SWidgetSwitcher::GetChildren ( )

overrideprotectedvirtual

All widgets must provide a way to access their children in a layout-agnostic way. Panels store their children in Slots, which creates a dilemma. Most panels can store their children in a TPanelChildren<Slot>, where the Slot class provides layout information about the child it stores. In that case GetChildren should simply return the TPanelChildren<Slot>. See StackPanel for an example.

Implements SPanel.

◆ GetNumWidgets()

int32 SWidgetSwitcher::GetNumWidgets ( ) const

inline

Gets the number of widgets that this switcher manages.

Returns: Number of widgets.

◆ GetTypedChildren()

TPanelChildren< FSlot > & SWidgetSwitcher::GetTypedChildren ( )

inlineprotected

◆ GetWidget()

TSharedPtr< SWidget > SWidgetSwitcher::GetWidget ( int32 SlotIndex ) const

Gets the widget in the specified slot.

Parameters

SlotIndex The slot index of the widget to get.

Returns: The widget, or nullptr if the slot does not exist.

◆ GetWidgetIndex()

int32 SWidgetSwitcher::GetWidgetIndex ( TSharedRef< SWidget > Widget ) const

Gets the slot index of the specified widget.

Parameters

Widget The widget to get the index for.

Returns: The slot index, or INDEX_NONE if the widget does not exist.

◆ OnArrangeChildren()

void SWidgetSwitcher::OnArrangeChildren	(	const FGeometry &	AllottedGeometry,
		FArrangedChildren &	ArrangedChildren
	)		const

overrideprotectedvirtual

Panels arrange their children in a space described by the AllottedGeometry parameter. The results of the arrangement should be returned by appending a FArrangedWidget pair for every child widget. See StackPanel for an example

Parameters

AllottedGeometry	The geometry allotted for this widget by its parent.
ArrangedChildren	The array to which to add the WidgetGeometries that represent the arranged children.

Implements SPanel.

◆ OnSlotAdded()

virtual void SWidgetSwitcher::OnSlotAdded ( int32 AddedIndex )

inlineprotectedvirtual

◆ OnSlotRemoved()

virtual void SWidgetSwitcher::OnSlotRemoved	(	int32	RemovedIndex,
		TSharedRef< SWidget >	RemovedWidget,
		bool	bWasActiveSlot
	)

inlineprotectedvirtual

◆ RemoveSlot()

int32 SWidgetSwitcher::RemoveSlot ( TSharedRef< SWidget > WidgetToRemove )

Removes a slot with the corresponding widget in it. Returns the index where the widget was found, otherwise -1.

Parameters

Widget The widget to find and remove.

◆ SetActiveWidget()

void SWidgetSwitcher::SetActiveWidget ( TSharedRef< SWidget > Widget )

inline

Sets the active widget.

Parameters

Widget The widget to activate.

◆ SetActiveWidgetIndex()

void SWidgetSwitcher::SetActiveWidgetIndex ( int32 Index )

Activates the widget at the specified index.

Parameters

Index The slot index.

◆ SLATE_BEGIN_ARGS()

SWidgetSwitcher::SLATE_BEGIN_ARGS ( SWidgetSwitcher )

inline

◆ Slot()

SWidgetSwitcher::FSlot::FSlotArguments SWidgetSwitcher::Slot ( )

static

Creates a new widget slot.

Returns: A new slot.

◆ ValidatePathToChild()

bool SWidgetSwitcher::ValidatePathToChild ( SWidget * InChild )

overridevirtual

Reimplemented from SWidget.
