Title: Trying to Figure out how to show a new Window
Post by: Geoffry_the_Deprogrammer on November 02, 2014, 11:04:13 pm

I am using SFML in C# and am having difficulties figuring out how to Display a second window in my program, there are no errors obvious with the code, as it runs fine, however it does not display the second window when commanded... I have no idea why, and I cant see any obvious issues having tried replicating the code for the first window...

If anyone has any idea what I might be doing wrong, or can tell me what I should try doing that would be much appreciated... :)

Please read this thread (http://en.sfml-dev.org/forums/index.php?topic=5559) and edit your question accordingly. Use code tags and keep the code minimal. To display a window, you don't need loads of classes, methods and properties :)

yeah, sorry, Im no good at communication with Humans, nonetheless I have attempted to make the question more simple, though I think ive just made it worse...

Well now there's simply no code, so we've no idea what you do are what you don't do.
Provide a minimal but complete example and make sure to use the code tag.

It's not minimal, lots of stuff we don't care about, given the problem...
I hope you realize that you can't have two fullscreen windows...

A minimal example would be: Entry point, Create two windows, optionally process events.

yeah, i realise that, I were just Trying to replicate my earlier code for the first window, and yeah, sorry its not minimal, but im really not sure where i should be looking as I have no idea what im doing wrong...

If you don't understand your own code, there isn't much we can do...

Remove all the code that don't make the problem disappear. Keep only what's needed to reproduce it.

snip...

Few things I noticed.

You are missing brackets from else clause:

             if (isFullScreen)
            {
                screenRes = VideoMode.DesktopMode;
                window = new RenderWindow(screenRes, "0", Styles.Fullscreen);
                windowencryipt = new RenderWindow(screenRes, "0", Styles.Fullscreen);
            }
            else
                window = new RenderWindow(screenRes, "0", Styles.Default);
                windowencryipt = new RenderWindow(screenRes, "0", Styles.Default);
            

Second while loop is never happening unless you close the first window, if you are going to render both of them you should do something like:

            while (Window.IsOpen() && WindowEncyript.IsOpen())
            {
                if (PreviousTick.Add(TickLength) <= DateTime.Now)
               {
                    Update();
                    Draw();
                }
             }

You are missing brackets in Update method so the second window always gets closed:

            if (Keyboard.IsKeyPressed(Keyboard.Key.Escape))
                window.Close();
                windowencryipt.Close();

Also not sure if you are aware of this but instead of writing

        private static Encryption encryption;
        public static Encryption Encryption
        {
            get { return encryption; }
        }

        private static RenderWindow window;
        public static RenderWindow Window
        {
            get { return window; }
            set { window = value; }
        }

You can just use

        public static Encryption Encryption {get; private set; }
        public static RenderWindow Window {get; set;}

thanks, yeah, it was just the missing bracket... I should probably be more observant of my own code... Thanks for the help... :)
