.Net resize window [Solved]
« on: January 19, 2014, 04:17:40 pm »
I want to know how to re-size view when i re-size pictureBox.

This is my code so far, but it doesn't work well:

private RenderWindow window = null;

SFML.Graphics.View view = new SFML.Graphics.View();

window = new RenderWindow(pictureBox1.Handle);

view.Reset(new FloatRect(0f, 0f, pictureBox1.Width, pictureBox1.Height));
           
window.SetView(view);

private void Form1_Resize(object sender, EventArgs e)
{
            view.Reset(new FloatRect(0f, 0f, pictureBox1.Width, pictureBox1.Height));
            window.SetView(view);
 
}

When i start program everything is great, but when i re-size window(pictureBox) all Sprites start to get wider when i reduce size and smaller when i increase size.

Are you sure the resized event handler gets called?

And also, maybe you should handle the picture box resized instead of the form resized (since SFML is hosted in the picturebox and not the form).

Can you post a complete and minimal example (something that I can copy and paste) that shows the problem? I have a few ideas what may be wrong, but first I need to see how you handle your form/drawing/events.

In your timer1_Tick you need to call window.DispatchEvents().

Also, I don't recommend using a timer to do your SFML drawing. I recommend you initialize SFML from outside the form as in the example I posted here. This can have a standard drawing loop with WinForms.  ;)
