#include "Components/Border.h"

Description

A single-child container that renders a configurable background brush (solid color, texture, or material) with padding. Commonly used to visually frame or highlight a section of UI.

Caveats & Gotchas

• UBorder holds only one child — it derives from UContentWidget. Use UOverlay or UCanvasPanel if you need a shared background behind multiple widgets.
• BrushColor tints the background image; ContentColorAndOpacity tints the child content. They are independent multipliers applied separately.
• For animated or parameterized backgrounds, call GetDynamicMaterial() to obtain or create a UMaterialInstanceDynamic that can be driven at runtime.

Example

Set a semi-transparent dark background C++

MyBorder->SetBrushColor(FLinearColor(0.05f, 0.05f, 0.05f, 0.8f));
MyBorder->SetPadding(FMargin(8.f));
