    copied!<p>I have the following the class: </p> <pre><code>//Rectangle.h #include "Point.h" class Rectangle{ public: Rectangle(); void setWidth(int); void setHeight(int); int getWidth(); int getHeight(); void draw(Point); private: int m_width; int m_height; }; //Rectangle.cpp #include &lt;Windows.h&gt; #include &lt;iostream&gt; #include &lt;GL/Gl.h&gt; #include &lt;GL/Glu.h&gt; #include &lt;GL/Glut.h&gt; #include "Rectangle.h" #include "Point.h" //constructor Rectangle::Rectangle(){ } int Rectangle::getHeight(){ return m_height; } int Rectangle::getWidth(){ return m_width; } void Rectangle::setHeight(int a_height){ m_height = a_height; } void Rectangle::setWidth(int a_width){ m_width = a_width; } void Rectangle::draw(Point center){ int pointWidth = m_width / 2; int pointHeight = m_height / 2; std::cout &lt;&lt; "drawing rectangle at" &lt;&lt; center.getX() &lt;&lt; ", " &lt;&lt; center.getY() &lt;&lt; std::endl; glColor3f(1, 1, 0); glBegin(GL_POLYGON); glVertex2i( center.getX() - pointWidth, center.getY() - pointHeight ); glVertex2i( center.getX() + pointWidth, center.getY() - pointHeight ); glVertex2i( center.getX() + pointWidth, center.getY() + pointHeight ); glVertex2i( center.getX() - pointWidth, center.getY() + pointHeight ); glEnd(); } </code></pre> <p>And then I have the following in main.cpp. The problem is with the line <code>vector&lt;Rectangle&gt; rectangles;</code> I get the following error:</p> <blockquote> <p>std::vector : Rectangle is not a valid template type argument for parameter '_Ty'</p> </blockquote> <pre><code>#include &lt;Windows.h&gt; #include &lt;math.h&gt; #include &lt;string&gt; #include "Rectangle.h" #include "Point.h" #include "Pentagon.h" #include "Star.h" #include "StringManip.h" #include &lt;iostream&gt; #include &lt;fstream&gt; #include &lt;vector&gt; #include &lt;GL/Gl.h&gt; #include &lt;GL/Glu.h&gt; #include &lt;GL/Glut.h&gt; using namespace std; // Function prototypes for callbacks void myDisplay(void); void myInit(); void openFile(string); Point point; vector&lt;Point&gt; points; vector&lt;Rectangle&gt; rectangles; vector&lt;Pentagon&gt; pentagons; vector&lt;Star&gt; stars; </code></pre> <p>I'm at a loss for what's up. I think I've done my class correctly. If anyone could tell me what's wrong, I'd appreciate it. </p> <p>Here's Point.h and Point.cpp</p> <pre><code>//Point.h #ifndef POINT_H #define POINT_H class Point { public: //default constructor Point () { m_xCoord = 0; m_yCoord = 0; } //set x and y void setX(int a_x); void setY(int a_y); //get x and y int getX(); int getY(); //change x and y by a specified value. void changeX(int a_x); void changeY(int a_y); private: int m_xCoord; int m_yCoord; }; #endif //Point.cpp #include "Point.h" void Point::setX(int a_x){ m_xCoord = a_x; } void Point::setY(int a_y){ m_yCoord = a_y; } int Point::getX(){ return m_xCoord; } int Point::getY(){ return m_yCoord; } void Point::changeX(int a_x){ m_xCoord += a_x; if(m_xCoord &lt; 0){ m_xCoord = 0; } } void Point::changeY(int a_y){ m_yCoord += a_y; if(m_yCoord &lt; 0){ m_yCoord = 0; } } </code></pre>
