我以爲我可以使用#pragma一次來解決我的問題,但它不起作用。#包含的問題
這是我的問題。
我有Agui.h,我想是我的主頭這一切包括: 這是它:
#pragma once
/*
This header includes all the required headers
required for Agui
Author: Josh
*/
//Standard library (STL)
#include <stdlib.h>
#include <iostream>
#include <string>
#include <sstream>
#include <vector>
#include <list>
#include <algorithm>
#include <queue>
//C runtime
#include <cmath>
#include <ctime>
//Allegro 5
#include <allegro5/allegro.h>
#include <allegro5/allegro5.h>
#include <allegro5/allegro_image.h>
#include <allegro5/allegro_primitives.h>
#include <allegro5/allegro_font.h>
#include <allegro5/allegro_ttf.h>
#include "AguiBaseTypes.h"
#include "AguiWidgetBase.h"
AguiBaseTypes.h看起來是這樣的:
#pragma once
#include "Agui.h"
#define AguiBitmap ALLEGRO_BITMAP
/*
This header contains classes for basic types.
These include:
Point,
Size,
Rectangle,
Color
and their floating equivalents

//integer Point class
class AguiPoint {
int x;
int y;
public:
int getX();
int getY();
void setX(int x);
void setY(int y);
void set(int x, int y);
AguiPoint(int x, int y);
AguiPoint();
std::string toString();
std::string xToString();
std::string yToString();
};
//floating version of Agui Point
class AguiPointf {
float x;
float y;
public:
float getX();
float getY();
void setX(float x);
void setY(float y);
void set(float x, float y);
AguiPointf(float x, float y);
AguiPointf(AguiPoint p);
AguiPointf();
std::string toString();
std::string xToString();
std::string yToString();
};
//Integer rectangle class
class AguiRectangle {
int x;
int y;
int width;
int height;
public:
bool isEmpty();
int getTop();
int getLeft();
int getBottom();
int getRight();
AguiPoint getTopLeft();
AguiPoint getBottomRight();
};
class AguiColor {
unsigned char r;
unsigned char g;
unsigned char b;
unsigned char a;
void verifyColorBounds();
public:
AguiColor(int r, int g, int b, int a);
AguiColor(float r, float g, float b, float a);
AguiColor();
int getR();
int getG();
int getB();
int getA();
};
和問題一,AguiWidgetBase.h
#pragma once
#include "Agui.h"
/*
This is the base class for all widgets
Author: Josh
*/
class AguiWidgetBase
{
//variables
AguiColor tintColor;
AguiColor fontColor;
//private methods
void zeroMemory();
virtual void onPaint();
virtual void onTintColorChanged(AguiColor color);
void (*onPaintCallback)(AguiRectangle clientRect);
void (*onTintColorChangedCallback)();
public:
AguiWidgetBase(void);
~AguiWidgetBase(void);
void paint();
void setTintColor(AguiColor color);
AguiColor getBackColor();
};
編譯器沒有看到AguiB AguiWidgetBase的aseTypes。這導致

我該如何解決這個問題?還有一種方法可以像我想要的那樣做到這一點,在哪裏隨處可見Agui.h,而不是隨着時間的推移會變得混亂的單個包含?

包含的.cpp文件導致錯誤的順序是什麼?您還可以使用user/showIncludes查看包含樹,並找出標題被拖入的順序... – Nick 2010-10-07 20:27:11
回滾到原始版本以查看頭文件中的依賴關係。 – quamrana 2010-10-07 21:25:21
