Introduction Still, as of UE 5.5, multi-line editable text boxes lack proper keyboard and gamepad navigation support. Let’s fix this without modifying the engine’s source code. I’ll experiment with a simple 2x2 grid of text boxes to demonstrate how we can implement smooth, unified navigation across both keyboard and gamepad input devices, which you can also recreate for testing purposes. Current Limitations Keyboard Arrow keys only allow navigation within the content of a single text box, and there’s no way to navigate between text boxes themselves....

Need to use third-party libraries that depend on spdlog in your Unreal project? Here’s how to simulate the spdlog API using Unreal’s native UE_LOG system, to let you avoid adding extra dependencies while keeping your code clean. We’ll create a logging utility class that matches the spdlog interface, handling type conversions to FString and formatting along the way. Implementation Here’s the code that bridges spdlog and Unreal’s logging system: #pragma once #include "Containers/UnrealString....

As of UE 5.4, the Common UI button (UCommonButtonBase) still doesn’t support direct focus settings. This is because UCommonButtonBase is derived from UUserWidget, which supports focusing, but doesn’t direct the focus to the underlying button itself automatically. However, you can still set the focus on the button by performing a “deep” focus on the Slate button. Here’s how you can achieve this: /** * Sets the focus on the button * This function performs the "deep" focus on the Common UI button, which means that it will set the focus on the button itself * This is useful since UCommonButtonBase is derived from UUserWidget, which doesn't support focus when setting it directly */ UFUNCTION(BlueprintCallable, Category = "mod....

Do not confuse Modular Features with Modular Gameplay Features . Introduction In Unreal Engine, Modular Features is a pretty straightforward system that makes it possible create and manage features that can be enabled or disabled at runtime. Features share the same base interface (derived from IModularFeatures), and they can be registered/unregistered at runtime from any part of the code and any module. This system is widely used in UE, for example, in audio capture, where each platform may have its audio capture implementation registered/unregistered based on the target platform, all using the base interface of IAudioCaptureFactory, which is derived from IModularFeatures....

In Unreal Engine, you can determine the currently focused widget in both Slate and UMG UI systems. Slate To get the currently focused Slate widget, you can use the following code snippet: // Instead of 0, you can pass the user index if you have multiple users TSharedPtr<SWidget> FocusedSlateWidget = FSlateApplication::Get().GetUserFocusedWidget(0); UMG Getting the currently focused UMG widget is a bit more involved, since there is no direct function to get it or the place where it is stored....
