Window#resize?

[jlnr]

There is a new forum thread about resizing windows or changing resolutions almost every week. :)

I think a good first addition would be Window#resize(width, height, fullscreen), but the question is, when are you allowed to call it? I think it should raise an exception when called from Window#draw but work everywhere else.

(Live-resizable windows are a related, but different issue.)

this should be easy making use of https://wiki.libsdl.org/SDL_SetWindowSize

Thanks for you nudging me! It was pretty straightforward. Needs some testing on Windows and Linux, then 0.10.9 is ready to go.

There's no API for resizing windows from Ruby, however you can resize by recalling initialize with a different resolution.

Example of a Ruby implementation of the resize method:

class Window < Gosu::Window
  def initialize(width, height)
    super
  end

  def resize(width, height, fullscreen=fullscreen?)
    initialize(width, height)
    self.fullscreen = fullscreen
  end
end

window = Window.new(1280, 720)
window.resize(1920, 1080, true)

Well, thats not exactly true, although you're right that its a bit hidden and not intuitive at the moment. You can set the width and height of an Window in the Ruby interface which triggers an resize.

%rename("width=") setWidth;
%rename("height=") setHeight;
%rename("fullscreen=") setFullscreen;

   void setWidth(unsigned width) {
        $self->resize(width, $self->height(), $self->fullscreen());
    }
    void setHeight(unsigned height) {
        $self->resize($self->width(), height, $self->fullscreen());
    }
    void setFullscreen(bool fullscreen) {
        $self->resize($self->width(), $self->height(), fullscreen);
    }

Don't know about the reasons for @jlnr to

%ignore Gosu::Window::resize(unsigned, unsigned, bool);

but maybe it can be rethought while we're working on #437

Ah, I never actually tried setting the width and height that way. It's quite a lot better than my method.
