ULimenNumberPad

Overview

ULimenNumberPad is a custom UMG widget designed to allow users to input numeric codes. It consists of a grid of number buttons (0-9), a submit button, and a clear button.

Usage & Implementation Notes

Threading Constraints: This widget does not perform any operations that require threading constraints.
Replication Requirements: No replication is required for this widget as it operates purely on client-side data.
Memory Lifetime Management: The widget manages memory for the buttons and screen using smart pointers (TSharedPtr and TStrongObjectPtr). Ensure proper management of these objects to avoid memory leaks.
Initialization Dependencies: This widget depends on ULimenStandardButton for its functionality. Ensure that this class is properly defined and available in your project.
