Slate Elements¶

Custom UI controls and enhanced widgets for inventory interfaces.

Core Components¶

Enhanced Widgets¶

UMounteaAdvancedInventoryAnimatedSwitcher - Animated panel transitions
UMounteaAdvancedInventoryButtonWidget - Gameplay tag-based buttons

Animated Switcher¶

Enhanced Functionality¶

Extends UCommonAnimatedSwitcher with completion callbacks:

// Event fired when animation completes
UPROPERTY(BlueprintAssignable)
FOnAnimationFinished OnAnimationFinished;

// Delegate signature
DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams(FOnAnimationFinished, UWidget*, ActiveWidget, int32, ActiveIndex);

Usage¶

// Bind to animation completion
AnimatedSwitcher->OnAnimationFinished.AddDynamic(this, &AMyActor::OnSwitchComplete);

void OnSwitchComplete(UWidget* ActiveWidget, int32 ActiveIndex)
{
    // Handle transition completion
    if (ActiveIndex == InventoryPanelIndex)
    {
        // Focus inventory panel
        ActiveWidget->SetFocus();
    }
}

Use Cases¶

Panel Transitions - Smooth switching between inventory/equipment/crafting
Tab Systems - Animated category selection
Modal Dialogs - Transition in/out effects

Inventory Button¶

Gameplay Tag Integration¶

// Enhanced button with action context
UPROPERTY(EditAnywhere, BlueprintReadWrite)
FGameplayTag ButtonActionTag;

UPROPERTY(EditAnywhere, BlueprintReadWrite) 
FString ButtonActionContext;

Theme Application¶

Automatically applies inventory theme when created:

virtual void ApplyTheme_Implementation() override;

Tags Usage¶

// Set button action
InventoryButton->ButtonActionTag = FGameplayTag::RequestGameplayTag("UI.Action.Equip");
InventoryButton->ButtonActionContext = "MainHand";

// Handle button press
void OnButtonClicked()
{
    if (ButtonActionTag.MatchesTag(EquipTag))
    {
        EquipItemToSlot(ButtonActionContext);
    }
}

Theme Integration¶

Both widgets integrate with the inventory theme system for consistent styling:

Color Application¶

Automatic theme color application
State-based styling (normal/hovered/pressed)
Level-based theming (primary/secondary/tertiary)

Runtime Updates¶

// Apply theme to custom widgets
UMounteaInventoryUIStatics::ApplyTheme(CustomWidget);

Best Practices¶

Use UMounteaAdvancedInventoryAnimatedSwitcher for smooth UI transitions
Leverage gameplay tags in buttons for flexible action handling
Apply themes consistently across all custom widgets
