namespace EAppMsgType

	/**
	 * Enumerates supported message dialog button types.

	enum Type
	{
		Ok,
		YesNo,
		OkCancel,
		YesNoCancel,
		CancelRetryContinue,
		YesNoYesAllNoAll,
		YesNoYesAllNoAllCancel,
		YesNoYesAll,

	 */
	enum Type
	{
		No,
		Yes,
		YesAll,
		NoAll,
		Cancel,
		Ok,
		Retry,
		Continue,
	};

前者为输入,后者会返回

可以通过返回类型的不同来做不同的逻辑

1
EAppReturnType::Type ReturnType = FMessageDialog::Open(EAppMsgType::OkCancel, DialogText);
  • 强行封装蓝图库
