UButton::SetColorAndOpacity
#include "Components/Button.h"
Access: public
Specifiers: UFUNCTIONBlueprintCallable
Description
Sets the color and opacity multiplier applied to the button's child content, not its background.
Caveats & Gotchas
- • Tints the content placed inside the button (text, icon, etc.) — use SetBackgroundColor to tint the button's own background brush instead.
- • Alpha below 1.0 fades the content but the button remains fully clickable; it does not disable input.
