DotNet / Re: SFML within windows forms
« on: May 24, 2019, 09:23:38 pm »
Hello,

I tried conect SFML window into already designed winform to overlap not-used panel.
Unfortunatelly the result is white window (instead black) and rectangle is not shown on them.
What do I wrong?

namespace SFML_test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            DrawingSurface rendersurface = new DrawingSurface();
            rendersurface.Size = new System.Drawing.Size(400, 200);
            splitContainer4.Panel1.Controls.Add(rendersurface);
            rendersurface.Location = new System.Drawing.Point(0, 0);

            // initialize sfml
            SFML.Graphics.RenderWindow renderwindow = new
            SFML.Graphics.RenderWindow(rendersurface.Handle);

            // drawing loop
            while (splitContainer4.Panel1.Visible)
            {
                System.Windows.Forms.Application.DoEvents();
                renderwindow.DispatchEvents();
                renderwindow.Clear(SFML.Graphics.Color.Black); // ---> but is white !!!
                renderwindow.Display();

                RectangleShape rec = new RectangleShape();
                rec.Position = new Vector2f(10, 10);
                rec.Size = new Vector2f(20, 20);
                rec.OutlineThickness = 1;
                rec.FillColor = SFML.Graphics.Color.Blue;
                rec.OutlineColor = SFML.Graphics.Color.Red;

                renderwindow.Draw(rec); // ---> but is not shown !!!
            }
        }
    }

    public class DrawingSurface : System.Windows.Forms.Control
    {
        protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
        {
        }
        protected override void OnPaintBackground(System.Windows.Forms.PaintEventArgs pevent)
        {
        }
    }

Graphics / Rotation convex shape (ver 2.2).
« on: October 17, 2018, 03:41:02 pm »
Hello,

I'm trying to rotate convex shape (3 vertex) but without no success.
Code is build as:
x = 400;
y = 400;
sf::ConvexShape polygon;
polygon.setPointCount(3);
polygon.setPoint(0, sf::Vector2f(x, y);
polygon.setPoint(1, sf::Vector2f(x-5, y-5));
polygon.setPoint(2, sf::Vector2f(x+5, y-5));

Now if I'm trying rotate it (by 10 degs) shape is moving away from point (400,400).
I tried to use Origin function but didn't help.

Not sure what's wrong here,
