Fullscreen mode

[Sur3]

Using alt+space window menu to get into the fullscreen mode is way to complicated.
There should be a command line option and maybe config file for starting in fullscreen mode. Also common key combinations like f or alt+enter for entering and leaving fullscreen seem not to work.

You can change the default size by setting the environment variable OSHU_WINDOW_SIZE, but can’t currently enable full-screen on startup. Adding that feature sounds easy enough though.

I think most window managers have a keyboard shortcut to make a window full-screen, so it can probably get simpler than invoking your menu. Still, I can understand you’d like oshu to start full-screen directly.

As I understand oshu is using SDL2 so toggling fullscreen mode could work similar to this:

if(fullscreen==0){ //enable window fullscreen mode
     SDL_SetWindowFullscreen(window,SDL_WINDOW_FULLSCREEN_DESKTOP);
     fullscreen=1; 
 }else if(fullscreen==1){ //disable fullscreen mode
     SDL_SetWindowFullscreen(window,0);
     fullscreen=0;
 }
