Detailed Description

The wrapper class for the SDL_Window class.

At the moment of writing it is not certain yet how many windows will be created. At least one as main window, but maybe the GUI dialogs will have their own window. Once that is known it might be a good idea to evaluate whether the class should become a singleton or not.

The class also wraps several functions operating on SDL_Window objects. For functions not wrapped the class offers an implicit conversion operator to a pointer to the SDL_Window object it owns.

Constructor & Destructor Documentation

◆ window() [1/2]

sdl::window::window ( const window & )

delete

◆ window() [2/2]

sdl::window::window	(	const std::string &	title,
		const int	x,
		const int	y,
		const int	w,
		const int	h,
		const uint32_t	window_flags,
		const uint32_t	render_flags
	)

Constructor.

The function calls SDL_CreateWindow and SDL_CreateRenderer.

Parameters

title	Used as title for SDL_CreateWindow.
x	Used as x for SDL_CreateWindow.
y	Used as y for SDL_CreateWindow.
w	Used as w for SDL_CreateWindow.
h	Used as x for SDL_CreateWindow.
window_flags	Used as flags for SDL_CreateWindow.
render_flags	Used as flags for SDL_CreateRenderer.

◆ fill()

void sdl::window::fill	(	uint8_t	r,
		uint8_t	g,
		uint8_t	b,
		uint8_t	a = `0`
	)

Clears the contents of the window with a given color.

Parameters

r	Red value of the color.
g	Green value of the color.
b	Blue value of the color.
a	Alpha value.

◆ get_output_size()

SDL_Point sdl::window::get_output_size ( )

Gets the window's renderer output size, in pixels.

Definition at line 111 of file window.cpp.

◆ get_size()

SDL_Point sdl::window::get_size ( )

Gets the window's size, in screen coordinates.

For the most part, this seems to return the same result as get_output_size. However, SDL indicates for high DPI displays these two functions could differ. I could not observe any change in behavior with DPI virtualization on or off, but to be safe, I'm keeping the two functions separate and using this for matters of window resolution.

◆ set_icon()

void sdl::window::set_icon ( const surface & icon )

Sets the icon of the window.

This is a wrapper for SDL_SetWindowIcon.

Note: The icon is a SDL_Surface and not a SDL_Texture, this is part of the SDL 2 API.

Parameters

icon	The new icon for the window.

◆ set_logical_size() [2/2]

void sdl::window::set_logical_size	(	int	w,
		int	h
	)

Sets the desired size of the rendering surface.

Input event coordinates will be scaled as if the window were also of this size. For best results this should be an integer fraction of the window size.

This is a wrapper for SDL_RenderSetLogicalSize.

Parameters

w	Width of the window's rendering surface
h	Height of the window's rendering surface
