Typedefs
template<typename T >
using	TArgumentsOf = typename TArgumentsOf_Struct<T>::Type
	Get the type of arguments from either a widget or a slot type (FArguments or FSlotArguments)

template<CWidgetOrSlot T>

Typedef Documentation

◆ TArgumentsOf

template<typename T >

using Mcro::Slate::TArgumentsOf = typename TArgumentsOf_Struct<T>::Type

Get the type of arguments from either a widget or a slot type (FArguments or FSlotArguments)

Definition at line 90 of file Slate.h.

◆ TAttributeBlock

template<CWidgetOrSlot T>

using Mcro::Slate::TAttributeBlock = TAttributeBlockFunctor<TArgumentsOf<T>>

An attribute block functor which takes in reference of FArguments or FSlotArguments and returns the same reference but presumably setting some Slate attributes before that. This is useful for modularizing the Slate declarative syntax.

Definition at line 159 of file Slate.h.

Function Documentation

◆ IsVisible()

MCRO_API EVisibility Mcro::Slate::IsVisible	(	bool	visible,
		EVisibility	hiddenState = EVisibility::Collapsed )

Convenience function for typing less when widget visibility depends on a boolean.

◆ SlotsFromTuples()

template<CFunctionLike Transform, Mcro::Range::CRangeOfTuplesCompatibleWithFunction< Transform > Range, CFunctionLike OnEmpty = TUniqueFunction<TFunction_Return<Transform>()>, CSlotArguments = TFunction_Return<Transform>>
requires (TFunction_ArgCount<Transform> >= 1)

auto Mcro::Slate::SlotsFromTuples	(	Range &&	range,
		Transform &&	transform,
		TOptional< OnEmpty > &&	onEmpty = {} )

Create widget slots from ranges of tuples via a transformation with structured binding arguments.

See also: Mcro::Range::TransformTuple

For example:

void SMyWidget::Construct(const FArguments& args)
{
    using namespace Mcro::Slate;
    
    ChildSlot
    [
        SNew(SVerticalBox)
        + SlotsFromTuples(args._DataMap, [](const FString& key, int32 value)
        {
            return MoveTemp(SVerticalBox::Slot()
                . HAlign(HAlign_Fill)
                . AutoHeight()
                [
                    SNew(SHorizontalBox)
                    + SHorizontalBox::Slot() [ SNew(STextBlock).Text(AsText(key)) ]
                    + SHorizontalBox::Slot() [ SNew(STextBlock).Text(AsText(value)) ]
                ];
            );
        })
        + SVerticalBox::Slot()
        . HAlign(HAlign_Fill)
        . AutoHeight()
        [
            SNew(STextBlock)
            . Text(INVTEXT_"Footer after the list of data")
        ]
    ];
}
