I define a line segment, the code is as follows:

 # pragma once 

#include 
using namespace std; 
The class line 
{
Private: 
Cstrings name;//curve name 
The float min;//the minimum 
Float Max;//Max 
Color line_color;//color value 
Int line_path;//track 
Int line_width;//line width 
Public: 
Vector The value;//curve values 
The line (void); 
~ the line (void); 
The line (TCHAR * m_name, float m_min, float m_max, Color m_line_color, int m_line_path, int m_line_width); 
Void Set_name (cstrings name);//set curve name 
Void Set_min (float min);//set the minimum 
Void Set_max (float Max);//set the maximum 
Void Set_color (Color line_color);//set colors 
Void Set_path (int line_path);//set the orbit 
Void Set_width (int line_width);//set the line width 

Cstrings return_name ();//return curve name 
Float return_min ();//return the minimum 
Float return_max ();//returns the maximum 
Color return_color ();//return color value 
Int return_path ();//return orbital value 
Int return_width ();//returns the line width values 
}; 
# include "StdAfx. H" 
H # include "line." 
//# include "afxtempl. H" 



Line: line (void) 
{
//id=yuwen shuxue of==NULL; 
Name=_T (" "); 
Min=0; 
Max=0; 
Line_color=Color (0, 0); 
Line_path=0; 
Line_width=1; 
}


The line: : ~ line (void) 
{
//delete [] name; 
}
Line: line (TCHAR * m_name, float m_min, float m_max, Color m_line_color, int m_line_path, int m_line_width) 
{

This - & gt; Name=m_name; 
This - & gt; Min=m_min; 
This - & gt; Max=m_max; 
This - & gt; Line_color=m_line_color; 
This - & gt; Line_path=m_line_path; 
This - & gt; Line_width=m_line_width; 
}
Void line: : Set_name (cstrings m_name)//set name 
{
This - & gt; Name=m_name; 
}
Void line: : Set_min (float m_min)//set the minimum 
{
This - & gt; Min=m_min; 
}
Void line: : Set_max (float m_max)//set the maximum 
{
This - & gt; Max=m_max; 
}
Void line: : Set_color (Color m_line_color)//set colors 
{
This - & gt; Line_color=m_line_color; 
}
Void line: : Set_path (int m_line_path)//set the orbit 
{
This - & gt; Line_path=m_line_path; 
}
Void line: : Set_width (int m_line_width)//set the line width 
{
This - & gt; Line_width=m_line_width; 
}

Cstrings line: : return_name ()//return curve name 
{
Return the name; 
}
Float line: : return_min ()//return the minimum 
{
Return min; 
}
Float line: : return_max ()//return the maximum 
{
return max; 
}
The Color line: : return_color ()//return Color value 
{
Return line_color; 
}
Int line: : return_path ()//return orbital value 
{
Return line_path; 
}
Int line: : return_width ()//return line width value 
{
Return line_width; 
}

Defines an object in the main program line NCO=line (_T (" near the C/O "), 0.4, 0.6, Color (0, 0), 1, 1);
And then put into the array line arrline [12]={NCO,,,,,,}, I through the NCO value. The push_back (1) enter a value, then through arrline [0]. Value [0] why not value? How to modify, the great god give directions? Is the need to turn the vector The value in private members the inside also? This fine: I don't know function: line (TCHAR * m_name, float m_min, float m_max, Color m_line_color, int m_line_path, int m_line_width) structure when initialized how ~ ~
