从昨晚开始,我就一直被这个问题困扰着,而且我一直无法弄清楚为什么会这样。我一定遗漏了一些非常简单的东西。
我正在制作一个 OpenGL 程序。在这个程序中,我正在创建一个 DialogBox 类。下面是代码:
//---------------------------------------------------------------
//DialogBox.h
//---------------------------------------------------------------
#include <vector>
class DialogBox
{
private:
float X; float Y; float Z;
float Width;
float Height;
float RED;
float GREEN;
float BLUE;
float ALPHA;
int currentLine;
int maxLines; //How many lines of text this dialog box can hold
int maxChars; //How many chars each line of text can hold
std::vector< std::vector<char> >Text; //Text contents of the Dialog Box
unsigned int vertexArray_DialogBox;
unsigned int vertexBuffer_DialogBox;
public:
DialogBox();
DialogBox(float width, float height);
void draw();
void draw(float x, float y, float z);
};
//------------------------------------------------------------------------
//DialogBox.cpp
//------------------------------------------------------------------------
#include <iostream>
#include "DialogBox.h"
DialogBox::DialogBox()
{
X = 0.0f; Y = 0.0f; Z = 0.0f;
Width = 1.0f;
Height = 1.0f;
RED = 0.0f;
GREEN = 1.0f;
BLUE = 1.0f;
ALPHA = 1.0f;
//For HELVETICA_18 ----------------------
static const float letter_width = 0.03f;
static const float letter_height = 0.04f;
static const float line_height = 0.1f;
//---------------------------------------
maxLines = Height / line_height - 4;
maxChars = Width / letter_width - 2;
Text.resize(maxLines);
for(int i = 0; i < maxLines; i++)
{
Text[i].resize(maxChars);
}
}
DialogBox::DialogBox(float width, float height)
{
Width = width;
Height = height;
//The rest of the initialization codes
}
void DialogBox::draw()
{
//OpenGL Drawing codes
}
void DialogBox::draw(float x, float y, float z)
{
X = x; Y = y; Z = z;
draw();
}
然后编译器抛出了这个错误信息:
我一直在努力,但我无法弄清楚编译器指的是什么。它必须是非常简单的东西(比如代码中的拼写错误或类似的东西)。预先感谢您的帮助。
最佳答案
同一行的警告是什么?
not enough actual parameters for macro 'DialogBoxA'
DialogBox
是一个#define
-d 宏吗?如果是这样,那可能会把事情搞砸。
