inconsistency on fullscreen stretching
« on: June 13, 2011, 01:55:19 am »
Hi

I want my windows to stretch when i put them on full screen as oposed to just resizing themselves to the size of the screen ( I want them to stay at the same resolution ), but i cant seem to be able to do this, it seems a little random if the window will strech or not, for example:

I had a piece of code where i had
App.Create( sf::VideoMode( 800, 600 ), "Test", sf::Style::Fullscreen );

and this didnt stretched the window, the window just increased its resolution to match the screens resolution. Then i thought "maybe its because of the lack of antialiasing... doesnt make much sence but lets give it a try", and so i tried:
App.Create( sf::VideoMode( 800, 600 ), "Test", sf::Style::Fullscreen, sf::WindowSettings( 24, 8, 4 ) );

and this actualy made the window stretch, i thought that was it, but then i removed that little bit again, to make sure that that was realy it, so i got back at:
App.Create( sf::VideoMode( 800, 600 ), "Test", sf::Style::Fullscreen );

But this time it stretched too. And then i tried the:
App.Create( sf::VideoMode( 800, 600 ), "Test", sf::Style::Fullscreen, sf::WindowSettings( 24, 8, 4 ) );

on a completly diferent program and i didnt saw any changes.


Sory if this text is a mess but really, this is really confusing me :\ how can i make the window stretch ( or not ) on fullscreen??

Btw, my monitor has 1920x1080 resolution.

OS: Win7 64
SFML: 1.6

I know now how to make it stretch by using views, but i still dont get it why it stretched in my example above :\

hmm ok, i will make execute some more tests to give more concrete info.
Can you just please tell me how it was suposed to work?

To my understanding if we dont use views on fullscreen the window will always resize to match our resolution right?

Might be me misunderstanding but I think you are looking for that the screen changes it's resolution to match the window resolution.

IE: If you have a window that is 800x600 and a screen that is 1024x768 and make the window go fullscreen, the screen will go down to that windows resolution. So everything will look bigger as there is "less" pixels to go around.

Exacly.

sory i wasnt too clear Laurent, i meant to ask how the fullscreen worked, if it normaly stretches to fit the screen or if it gives the window the screens resolution.

Fullscreen only works correctly if you pass a valid videomode. You can look it up in the documentation:

http://www.sfml-dev.org/documentation/2.0/classsf_1_1Window.php

Quote
An optional style can be passed to customize the look and behaviour of the window (borders, title bar, resizable, closable, ...). If style contains Style::Fullscreen, then mode must be a valid video mode.


You are telling the create function to make a fullscreen window with 800x600 resolution, which may not be a valid value. To be certain of what video modes your screen accepts, you can use GetFullscreenModes () (documentation for VideoMode class found here: http://www.sfml-dev.org/documentation/2.0/classsf_1_1VideoMode.php) which provides a vector with all the valid video modes.

If you just want to use the current resolution and bitdepth of the desktop, you can use GetDesktopMode().

The question I have to ask is, what is it that you want? Do you want to stretch a low resolution over the full screen (things will look pixelated and large) or get the full screen at the native resolution of the monitor (1920x1080)?

If it's the former, you need to make sure the resolution you are requesting is valid (use GetFullscreenModes() ). If it's the latter, DON'T specify a lower resolution and use GetDesktopMode().

To answer the last question: The default behavior is to provide you with the resolution you asked for. The documentation doesn't say what happens when the value is not valid, which means you should be making sure the value is valid before creating a full screen window.
