Member Function Documentation

◆ Advanced_AsInvalidationRoot()

const FSlateInvalidationRoot * SInvalidationPanel::Advanced_AsInvalidationRoot ( ) const
overrideprotectedvirtual

Reimplemented from SWidget.

◆ Advanced_IsInvalidationRoot()

bool SInvalidationPanel::Advanced_IsInvalidationRoot ( ) const
overrideprotectedvirtual

Reimplemented from SWidget.

◆ Construct()

void SInvalidationPanel::Construct ( const FArguments &  InArgs)

◆ CustomPrepass()

bool SInvalidationPanel::CustomPrepass ( float  LayoutScaleMultiplier)
overrideprotectedvirtual

Reimplemented from SWidget.

◆ GetAllChildren()

FChildren * SInvalidationPanel::GetAllChildren ( )
overridevirtual

Returns the children (if any) of this widget that are used by the invalidation system. This is used by the FastPath system to generate the correct information for every widget.

Note
Prefer GetChildren. Some widget may hide widget from you.
Should be name GetFastPathChildren or GetInvalidationChildren

Reimplemented from SWidget.

◆ GetCanCache()

bool SInvalidationPanel::GetCanCache ( ) const

Returns true when the invalidation panel is able to cache the widgets.

◆ GetChildren()

FChildren * SInvalidationPanel::GetChildren ( )
overridevirtual

Returns the useful children (if any) of this widget. Some widget type may hide widget if they are needed by the system. Allows for iteration over the Widget's children regardless of how they are actually stored.

Note
Should be renamed to GetVisibleChildren (not ALL children will be returned in all cases).

Reimplemented from SCompoundWidget.

◆ GetRootWidget()

TSharedRef< SWidget > SInvalidationPanel::GetRootWidget ( )
overrideprotectedvirtual
Returns
the children root widget of the Invalidation root.

Implements FSlateInvalidationRoot.

◆ OnPaint()

int32 SInvalidationPanel::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
ArgsAll the arguments necessary to paint this widget (
AllottedGeometryThe FGeometry that describes an area in which the widget should appear.
MyCullingRectThe rectangle representing the bounds currently being used to completely cull widgets. Unless IsChildWidgetCulled(...) returns true, you should paint the widget.
OutDrawElementsA list of FDrawElements to populate with the output.
LayerIdThe Layer onto which this widget should be rendered.
InColorAndOpacityColor and Opacity to be applied to all the descendants of the widget being painted
bParentEnabledTrue if the parent of this widget is enabled.
Returns
The maximum layer ID attained by this widget or any of its children.

Reimplemented from SCompoundWidget.
