Graphics / Re: problem with sf::VertexArray

If by "my window is not open" you mean it doesn't appear though your application is running - have you put the necessary dlls in the working directory of your program?

i mean window very soon closed after opening,

hey, im beginner in sfml and here i want  draw one vertex between two points but when i call window.draw(lines); I get an error: Use undeclared identifier "lines"
what should i do?
thanks

   sf::RenderWindow window(sf::VideoMode(600, 400), "Convex Hull");

   
   
    std::vector<sf::RectangleShape> rects;
   
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event) )
        {
       
       
       
       
            if (event.type == sf::Event::Closed)
                window.close();
            else if (event.type == sf::Event::MouseButtonPressed &&
                     event.mouseButton.button == sf::Mouse::Left&&
                     rects.size() < 10) {
               
                posx.push_back(event.mouseButton.x);
                posy.push_back(event.mouseButton.y);
               
//                cout << posx[f] << "   " << posy[f] << endl;
                f++;
               
//                cout << f << endl;
                sf::RectangleShape rect { { 2, 2 } };
                rect.setPosition(sf::Vector2f(sf::Mouse::getPosition(window)));
                rect.setFillColor(sf::Color::Green);
                rects.push_back(rect);
               
                cout << &rects << endl;
               
                sf::VertexArray lines(sf::LinesStrip, 2);
                lines[0].position = sf::Vector2f(posx[0], posy[0]);
                lines[1].position = sf::Vector2f(posx[10], posy[10]);

i want use muose click and get some positions in window, and set positions for draw some rectangles, but i have two problem,

1- i dont know where set number of point should press by user;(for example just 10 positions)
2- my rectangle not saved on screen, when user click on new position The previous rectangle Removed،

 while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
           
           
           
            switch (event.type) {
                case sf::Event::Closed:
                    window.close();
                    break;
                case sf::Event::MouseButtonPressed: ;
                   
                    cout << "Mouse button has been pressed " << endl;
                   
                    cout << event.mouseButton.x << "   " << event.mouseButton.y << endl;
                   
                    posx=event.mouseButton.x;
                    posy=event.mouseButton.y;
               
                   
                   
                    break;
       
                   
                    }
           
           
           
            sf::RectangleShape Rectangle;
 
                Rectangle.setSize(sf::Vector2f(3, 3));
                Rectangle.setOutlineColor(sf::Color::Green);
                Rectangle.setFillColor(sf::Color::Green);
                Rectangle.setPosition(posx,posy);

           
            window.clear();

Graphics / Re: draw rectangle---- 2 or more with different position

« on: May 10, 2014, 06:51:29 pm »

Thanks for answering
user interface of my program is command line,
yes of course ، i use render window، look...

VideoMode videoMode(x_main,y_main);
    RenderWindow window(videoMode,"Rectangle Bin-packing");

x_mian and y_main are Length and width of main rectangle, and set by user in command line...

how can i use this code in a loop, draw 2 or more time rectangles with different position in one compile?

RectangleShape rectangle;
    rectangle.setPosition(30,10);
    rectangle.setSize(Vector2f(100, 30));
    rectangle.setFillColor(Color::Yellow);
    rectangle.setOutlineColor(Color::Red);
    rectangle.setOutlineThickness(2);

excuse me im beginner

thanks for your reply,,,
excuse me i have many mistake in my writing because english is not my main language,
i want create a program for rectangle bin packing and i want to use SFML to solve this problem,

in this program i have many rectangles with different size and different position and All these Be set by the user,
i use

RectangleShape rectangle;

in one (for) loop but not worked and don't show the rectangles, now my question is here What should I use for show rectangles?
thanks again

but i can draw just one rectangle, what should i do for more draw with different position,
thanks
