导读：我在这里创建了这个课： //整数矩形类 class AguiRectangle { int x; int y; int width; int height;public: bool isEmpty { return x == 0 y == 0 width == 0 height == 0; } int getTop() { return x; } int getLeft() { return y; } int getBottom() { re

我在这里创建了这个课：
//整数矩形类 class AguiRectangle {
int x;
int y;
int width;
int height;
public:
bool isEmpty {
return x == 0 && y == 0 &&
width == 0 && height == 0;
}
int getTop() {
return x;
}
int getLeft() {
return y;
}
int getBottom() {
return y + height;
}
int getRight() {
return x + width;
}
AguiPoint getTopLeft()
{
return AguiPoint(getTop(),getLeft());
}
AguiPoint getBottomRight()
{
return AguiPoint(this->getBottom(),this->getRight());
}
};
编译器告诉我x和y以及宽度和高度是未声明的.这几乎就像班级没有看到自己. 谢谢 Error 14 error C2673: 'getBottomRight' : global functions do not have 'this' pointers c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 178 Error 16 error C2673: 'getBottomRight' : global functions do not have 'this' pointers c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 178 Error 13 error C2665: 'AguiPoint::AguiPoint' : none of the 4 overloads could convert all the argument types c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 174 Error 6 error C2628: 'AguiRectangle' followed by 'int' is illegal (did you forget a ';'?) c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 158 Error 3 error C2473: 'isEmpty' : looks like a function definition,but there is no parameter list. c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 153 Error 5 error C2238: unexpected token(s) preceding ';' c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 156 Error 17 error C2227: left of '->getRight' must point to class/struct/union/generic type c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 178 Error 15 error C2227: left of '->getBottom' must point to class/struct/union/generic type c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 178 Error 2 error C2146: syntax error : missing ';' before identifier 'result' c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 64 Error 19 error C2143: syntax error : missing ';' before '}' c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 180 Error 21 error C2079: 'pp' uses undefined class 'AguiPointf' c:UsersJoshDocumentsVisual Studio 2008ProjectsAguiAlleg_5main.cpp 35 Error 8 error C2065: 'y' : undeclared identifier c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 162 Error 9 error C2065: 'y' : undeclared identifier c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 166 Error 7 error C2065: 'x' : undeclared identifier c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 159 Error 11 error C2065: 'x' : undeclared identifier c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 169 Error 12 error C2065: 'width' : undeclared identifier c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 169 Error 10 error C2065: 'height' : undeclared identifier c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 166 Error 4 error C2059: syntax error : 'return' c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 155 Error 18 error C2059: syntax error : '}' c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 180 Error 20 error C2059: syntax error : '}' c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 180 Error 1 error C2027: use of undefined type 'AguiPointf' c:usersjoshdocumentsvisual studio 2008projectsaguialleg_5AguiAguiBaseTypes.h 59 解决方法
应该
