在STUMenuWidget实现退出逻辑

1. 添加属性: 按钮
   
   protected

ShootThemUp: Menu/UI/STUMenuWidget.h
   

   Copy1UPROPERTY(meta = (BindWidget))
   2UButton *QuitGameButton;

2. 实现回调函数
   
   private

ShootThemUp: Menu/UI/STUMenuWidget.h
   

   Copy1UFUNCTION()
   2void OnQuitGame();

   ShootThemUp: Menu/UI/STUMenuWidget.cpp
   

   Copy1#include "Kismet/KismetSystemLibrary.h"
   2
   3void USTUMenuWidget::OnQuitGame()
   4{
   5    UKismetSystemLibrary::QuitGame(this, GetOwningPlayer(), EQuitPreference::Quit, true);
   6}

3. 在NativeOnInitialized注册回调函数
   
   ShootThemUp: Menu/UI/STUMenuWidget.cpp
   

   Copy1// NativeOnInitialized
   2
   3if (QuitGameButton)
   4{
   5    QuitGameButton->OnClicked.AddDynamic(this, &USTUMenuWidget::OnQuitGame);
   6}
