Make window hidden when created
« on: December 18, 2012, 06:16:05 am »
Hello, I'm using SFML 2.0 and am trying to make a simple game using small textures. I want it to display at x2 the original size when first loaded, so immediately after creating the renderwindow I resize and move it.

int windowScale = 2;
sf::RenderWindow window(sf::VideoMode(256, 256), "Resize test");
window.setSize(sf::Vector2u(window.getSize().x*windowScale,window.getSize().x*windowScale));
window.setPosition(window.getPosition()-sf::Vector2i(window.getPosition().x/windowScale,window.getPosition().y)/windowScale);

//...rest of code
 

Here's the problem, the small screen appears for a brief moment before resizing.

Is there any way to make a window hidden until after it's resized?
I even tried hiding it using setVisible to hide it immediately after creation, resizing, then making it visible again. It didn't work.

You probably don't need to hide it like this in the first place.

Create the window at twice the size and then apply an sf::View with the size that you want your game to be.

Example:
int windowScale = 2;
int windowSize = 256;
sf::RenderWindow window(sf::VideoMode(windowSize*windowScale, windowSize*windowScale), "Resize test");
//window resolution is 1060x1060
sf::View gameView;
gameView.setSize(windowSize, windowSize);

window.setView(gameView);
//display resolution is now 256x256
//window is still 1060x1060 pixels large

//...rest of code

Thanks, I haven't messed with view much yet. It worked perfect.  Except I had to recenter it.

Final working code for a square screen.
int windowScale = 2;
int windowSize = 256;
sf::RenderWindow window(sf::VideoMode(windowSize*windowScale, windowSize*windowScale), "Resize test");

sf::View gameView;
gameView.setSize(windowSize, windowSize);
gameView.setCenter(windowSize/2,windowSize/2);
window.setView(gameView);

//...rest of code
