yep, that’s what I said in the mail :-) I just added the SDL_WINDOW_FULLSCREEN_DESKTOP flag to explain that, *without* changing resolutions, everything runs fine. But, as I said in the mail : when I change it to SDL_WINDOW_FULLSCREEN instead, nothing happens :-) > On 26 Sep 2016, at 14:11, Kai Sterker <[email protected]> wrote: > > Have never tried multiple windows fullscreen on multiple monitors, but one thing that sticks out immediately is you using the SDL_WINDOW_FULLSCREEN_DESKTOP flag. This will not change resolution, but always keep current desktop resolution. At the very least, you'd want to use SDL_WINDOW_FULLSCREEN instead. > > See https://wiki.libsdl.org/SDL_WindowFlags > > Kai > > On Mon, Sep 26, 2016 at 1:41 PM, jeroen clarysse <[email protected]> wrote: > > > > hi all, > > > > using THREE monitors, and trying to create two SDL_windows like this : > > > > int display_main_num = 1; > > int display_2nd_num = 2; > > > > m_main_window_w = 1024; > > m_main_window_h = 768; > > m_2nd_window_w = 1024; > > m_2nd_window_h = 768; > > > > m_main_window = SDL_CreateWindow("Main window",SDL_WINDOWPOS_CENTERED_DISPLAY(display_main_num),SDL_WINDOWPOS_CENTERED_DISPLAY(display_main_num),m_main_window_w,m_main_window_h,SDL_WINDOW_SHOWN|SDL_WINDOW_FULLSCREEN_DESKTOP); > > m_main_renderer = SDL_CreateRenderer(m_main_window, -1, SDL_RENDERER_SOFTWARE); > > > > m_2nd_window = SDL_CreateWindow("2nd window",SDL_WINDOWPOS_CENTERED_DISPLAY(display_2nd_num),SDL_WINDOWPOS_CENTERED_DISPLAY(display_2nd_num),m_2nd_window_w,m_2nd_window_h,SDL_WINDOW_SHOWN|SDL_WINDOW_FULLSCREEN_DESKTOP); > > m_2nd_renderer = SDL_CreateRenderer(m_2nd_window, -1, SDL_RENDERER_SOFTWARE); > > > > > > this works nicely, but these call don't change resolutions yet. However, when I change the flags SDL_WINDOW_FULLSCREEN_DESKTOP to SDL_WINDOW_FULLSCREEN, SDL is supposed to change the resolution of both monitors to 1024 x 768. A lot happens on the screen : flickering windows, typical macos fullscreen resizing animation, flashing menu bar, … but the whole function stays stuck in he first CreateWindow() call > > > > after I click around a bit, the code continues, but the windows are NOT fullscreen. > > > > has anyone succeeded in using multiple displays WITH resolution changes ? > > > > > > I also tried with using only ONE display resolution and leaving the other at desktop res, but even that didn’t work > > _______________________________________________ > > SDL mailing list > > [email protected] > > http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org > > _______________________________________________ > SDL mailing list > [email protected] > http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org _______________________________________________ SDL mailing list [email protected] http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org
