## Detailed Description

VideoMode defines a video mode (width, height, bpp)

A video mode is defined by a width and a height (in pixels) and a depth (in bits per pixel).

Video modes are used to setup windows (sf::Window) at creation time.

The main usage of video modes is for fullscreen mode: indeed you must use one of the valid video modes allowed by the OS (which are defined by what the monitor and the graphics card support), otherwise your window creation will just fail.

sf::VideoMode provides a static function for retrieving the list of all the video modes supported by the system: getFullscreenModes().

A custom video mode can also be checked directly for fullscreen compatibility with its isValid() function.

Additionally, sf::VideoMode provides a static function to get the mode currently used by the desktop: getDesktopMode(). This allows to build windows with the same size or pixel depth as the current resolution.

Usage example:

// Display the list of all the video modes available for fullscreen
std::vector<sf::VideoMode> modes = sf::VideoMode::getFullscreenModes();
for (std::size_t i = 0; i < modes.size(); ++i)
{
sf::VideoMode mode = modes[i];
std::cout << "Mode #" << i << ": "
<< mode.width << "x" << mode.height << " - "
<< mode.bitsPerPixel << " bpp" << std::endl;
}
// Create a window with the same pixel depth as the desktop
sf::VideoMode desktop = sf::VideoMode::getDesktopMode();
window.create(sf::VideoMode(1024, 768, desktop.bitsPerPixel), "SFML window");

## Constructor & Destructor Documentation

sf::VideoMode::VideoMode | ( |  | ) |

Default constructor.

This constructors initializes all members to 0.

sf::VideoMode::VideoMode | ( | unsigned int | modeWidth,
|  | unsigned int | modeHeight,
|  | unsigned int | modeBitsPerPixel = `32`
| ) |  |

Construct the video mode with its attributes.

Parameters

  modeWidth | Width in pixels
  modeHeight | Height in pixels
  modeBitsPerPixel | Pixel depths in bits per pixel

## Member Function Documentation

static VideoMode sf::VideoMode::getDesktopMode | ( |  | ) |
| static

Get the current desktop video mode.

Returns
  Current desktop video mode

static const std::vector<VideoMode>& sf::VideoMode::getFullscreenModes | ( |  | ) |
| static

Retrieve all the video modes supported in fullscreen mode.

When creating a fullscreen window, the video mode is restricted to be compatible with what the graphics driver and monitor support. This function returns the complete list of all video modes that can be used in fullscreen mode. The returned array is sorted from best to worst, so that the first element will always give the best mode (higher width, height and bits-per-pixel).

Returns
  Array containing all the supported fullscreen modes

bool sf::VideoMode::isValid | ( |  | ) | const

Tell whether or not the video mode is valid.

The validity of video modes is only relevant when using fullscreen windows; otherwise any video mode can be used with no restriction.

Returns
  True if the video mode is valid for fullscreen mode

Overload of != operator to compare two video modes.

Parameters

  left | Left operand (a video mode)
  right | Right operand (a video mode)

Returns
  True if modes are different

bool operator< | ( | const VideoMode & | left,

Overload of < operator to compare video modes.

Parameters

  left | Left operand (a video mode)

|  | const VideoMode & | right
| ) |  |
| related

Parameters

  left | Left operand (a video mode)
  right | Right operand (a video mode)

Returns
  True if left is lesser or equal than right

bool operator== | ( | const VideoMode & | left,
|  | const VideoMode & | right
| ) |  |
| related

Overload of == operator to compare two video modes.

Parameters

  left | Left operand (a video mode)
  right | Right operand (a video mode)

Returns
  True if modes are equal

|  | const VideoMode & | right
| ) |  |
| related

Overload of > operator to compare video modes.

Parameters

  left | Left operand (a video mode)
  right | Right operand (a video mode)

Returns
  True if left is greater than right

bool operator>= | ( | const VideoMode & | left,
|  | const VideoMode & | right
| ) |  |
| related

Overload of >= operator to compare video modes.

Parameters

  left | Left operand (a video mode)
  right | Right operand (a video mode)

Returns
  True if left is greater or equal than right
