Graphics / Solved

Thank you so much!! It turned out that I was defining the rectangle, then setting the position when I didn't need to set the position. Thanks!

Graphics / Drawing a click and drag rectangle?

« on: January 14, 2011, 02:22:08 am »

Hey, I would like to draw a rectangle that resizes when the user move the mouse. Like when you click and drag on a desktop. I tried doing it with this code:

Code: [Select]

 while(drag){
                    while(StartWindow.GetEvent(Event)){

                        sf::Vector2f coords = StartWindow.ConvertCoords(StartWindow.GetInput().GetMouseX(),StartWindow.GetInput().GetMouseY());
                        x2 = coords.x;
                        y2 = coords.y;
                        rectangle = sf::Shape::Rectangle(x,y,x2,y2,sf::Color::Blue,1,sf::Color::Red);
                        StartWindow.SetView(StartWindow.GetDefaultView());
                        rectangle.SetPosition(x,y);
                         StartWindow.Draw(rectangle);
}

This code is pretty incomplete, but its supposed to make a drag-able rectangle selection tool. This does draw the rectangle, but not where the the user clicks. Can anyone help me with this code, or suggest some new code? Thanks.

Window / Getting coordinates from views?

« on: January 05, 2011, 03:53:39 pm »

Hey I am making a program and I need it to be a "pannable" program. I need to be able to move around a view that is larger than the screen. So when detecting mouse clicks with window.GetInput().GetMouseX() does that give me the x coordinate of the screen, or the x coordinate of the mouse in the view? If this is the x coordinate in the screen, is there a way to get where the user clicks in the entire view? Thanks for any help.

Graphics / Displaying user-created objects??

« on: September 11, 2010, 12:45:00 am »

Hi. In my program I'm trying to let the user click anywhere on the screen and the program will draw a circle there. I get the coords using GetMouseX amd GetMouseY. How would I redraw these in the main loop? I tried making an array, but I get errors. Is there some easy, commonly used method for displaying objects created while the program is running?
