编辑器扩展：消息窗口

前言

自定义和扩展消息窗口

消息窗口

先看两个枚举

namespace EAppMsgType
{
	/**
	 * Enumerates supported message dialog button types.
	 */
	enum Type
	{
		Ok,
		YesNo,
		OkCancel,
		YesNoCancel,
		CancelRetryContinue,
		YesNoYesAllNoAll,
		YesNoYesAllNoAllCancel,
		YesNoYesAll,
	};

namespace EAppReturnType
{
	/**
	 * Enumerates message dialog return types.
	 */
	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

	EAppReturnType::Type ReturnType = FMessageDialog::Open(EAppMsgType::OkCancel, DialogText);

• 强行封装蓝图库

UENUM(BlueprintType)
enum class EMsgType : uint8
{
	Ok,
	YesNo,
	OkCancel,
	YesNoCancel,
	CancelRetryContinue,
	YesNoYesAllNoAll,
	YesNoYesAllNoAllCancel,
	YesNoYesAll,

};
UENUM(BlueprintType)
enum class EMsgRetType : uint8
{
	No,
	Yes,
	YesAll,
	NoAll,
	Cancel,
	Ok,
	Retry,
	Continue,

};

EMsgRetType UFlib_IO::OpenMessageWindow(EMsgType Type, FText Msg)
{
	EAppMsgType::Type  tp;
	switch (Type)
	{
	case EMsgType::Ok:
	tp = EAppMsgType::Ok; 
		break;
	case EMsgType::YesNo:
		tp = EAppMsgType::YesNo;
		break;
	case EMsgType::OkCancel:
		tp = EAppMsgType::OkCancel;
		break;
	case EMsgType::YesNoCancel:
		tp = EAppMsgType::YesNoCancel;
		break;
	case EMsgType::CancelRetryContinue:
		tp = EAppMsgType::CancelRetryContinue;
		break;
	case EMsgType::YesNoYesAllNoAll:
		tp = EAppMsgType::YesNoYesAllNoAll;
		break;
	case EMsgType::YesNoYesAllNoAllCancel:
		tp = EAppMsgType::YesNoYesAllNoAllCancel;
		break;
	case EMsgType::YesNoYesAll:
		tp = EAppMsgType::YesNoYesAll;
		break;
	}
	EAppReturnType::Type retType = FMessageDialog::Open(tp, Msg);
	EMsgRetType returnType = EMsgRetType::Ok;
	switch (retType)
	{
	case EAppReturnType::No:
		returnType = EMsgRetType::No;
		break;
	case EAppReturnType::Yes:
		returnType = EMsgRetType::Yes;
		break;
	case EAppReturnType::YesAll:
		returnType = EMsgRetType::YesAll;
		break;
	case EAppReturnType::NoAll:
		returnType = EMsgRetType::NoAll;
		break;
	case EAppReturnType::Cancel:
		returnType = EMsgRetType::Cancel;
		break;
	case EAppReturnType::Ok:
		returnType = EMsgRetType::Ok;
		break;
	case EAppReturnType::Retry:
		returnType = EMsgRetType::Retry;
		break;
	case EAppReturnType::Continue:
		returnType = EMsgRetType::Continue;
		break;
	}
	return returnType;
}
