## Function Documentation

## ◆ sfMouse_getPositionRenderWindow()

sfVector2i sfMouse_getPositionRenderWindow | ( | const sfRenderWindow * | relativeTo | ) |

Get the current position of the mouse relative to a render-window.

This function returns the current position of the mouse cursor relative to the given render-window, or desktop if NULL is passed.

Parameters

  relativeTo | Reference window

Returns
  Position of the mouse cursor, relative to the given render window

## ◆ sfMouse_setPositionRenderWindow()

void sfMouse_setPositionRenderWindow | ( | sfVector2i | position,
|  | const sfRenderWindow * | relativeTo )

Set the current position of the mouse relative to a render window.

This function sets the current position of the mouse cursor relative to the given render-window, or desktop if NULL is passed.

Parameters

  position | New position of the mouse
  relativeTo | Reference window

## ◆ sfRenderWindow_capture()

sfImage * sfRenderWindow_capture | ( | const sfRenderWindow * | renderWindow | ) |

Copy the current contents of the window to an image.

Deprecated
  Use a sfTexture and its sfTexture_updateFromRenderWindow(sfTexture*, const sfRenderWindow*, unsigned int, unsigned int) function and copy its contents into an sfImage instead.

sfVector2u windowSize = sfRenderWindow_getSize(window);
sfTexture* texture = sfTexture_create(windowSize.x, windowSize.y);
sfTexture_updateFromRenderWindow(texture, window, windowSize.x, windowSize.y);
sfImage* screenshot = sfTexture_copyToImage(texture);

sfRenderWindow_getSize
sfVector2u sfRenderWindow_getSize(const sfRenderWindow *renderWindow)
Get the size of the rendering region of a render window.
sfTexture_create
sfTexture * sfTexture_create(unsigned int width, unsigned int height)
Create a new texture.
sfTexture_updateFromRenderWindow
void sfTexture_updateFromRenderWindow(sfTexture *texture, const sfRenderWindow *renderWindow, unsigned int x, unsigned int y)
Update a texture from the contents of a render-window.
sfTexture_copyToImage
sfImage * sfTexture_copyToImage(const sfTexture *texture)
Copy a texture's pixels to an image.

Definition Vector2.h:50
sfVector2u::x
unsigned int x
Definition Vector2.h:51
sfVector2u::y
unsigned int y
Definition Vector2.h:52

This is a slow operation, whose main purpose is to make screenshots of the application. If you want to update an image with the contents of the window and then use it for drawing, you should rather use a sfTexture and the sfTexture_updateFromWindow(sfTexture*, const sfWindow*, unsigned int, unsigned int) function. You can also draw things directly to a texture with the sfRenderTexture class.

## ◆ sfRenderWindow_mapCoordsToPixel()

sfVector2i sfRenderWindow_mapCoordsToPixel | ( | const sfRenderWindow * | renderWindow,
|  | sfVector2f | point,
|  | const sfView * | view )

Convert a point from world coordinates to window coordinates.

This function finds the pixel of the render-window that matches the given 2D point. In other words, it goes through the same process as the graphics card, to compute the final position of a rendered point.

Initially, both coordinate systems (world units and target pixels) match perfectly. But if you define a custom view or resize your render-window, this assertion is not true anymore, ie. a point located at (150, 75) in your 2D world may map to the pixel (10, 50) of your render-window – if the view is translated by (140, 25).

This version uses a custom view for calculations, see the other overload of the function if you want to use the current view of the render-window.

Parameters

  renderWindow | Render window object
  point | Point to convert
  view | The view to use for converting the point

Returns
  The converted point, in target coordinates (pixels)

## ◆ sfRenderWindow_mapPixelToCoords()

sfVector2f sfRenderWindow_mapPixelToCoords | ( | const sfRenderWindow * | renderWindow,
|  | sfVector2i | point,
|  | const sfView * | view )

Convert a point from window coordinates to world coordinates.

This function finds the 2D position that matches the given pixel of the render-window. In other words, it does the inverse of what the graphics card does, to find the initial position of a rendered pixel.

Initially, both coordinate systems (world units and target pixels) match perfectly. But if you define a custom view or resize your render-window, this assertion is not true anymore, ie. a point located at (10, 50) in your render-window may map to the point (150, 75) in your 2D world – if the view is translated by (140, 25).

This function is typically used to find which point (or object) is located below the mouse cursor.

This version uses a custom view for calculations, see the other overload of the function if you want to use the current view of the render-window.

Parameters

  renderWindow | Render window object
  point | Pixel to convert
  view | The view to use for converting the point

Returns
  The converted point, in "world" units

## ◆ sfRenderWindow_pollEvent()

sfBool sfRenderWindow_pollEvent | ( | sfRenderWindow * | renderWindow,
|  | sfEvent * | event )

Get the event on top of event queue of a render window, if any, and pop it.

Parameters

  renderWindow | Render window object
  event | Event to fill, if any

Returns
  sfTrue if an event was returned, sfFalse if event queue was empty

## ◆ sfRenderWindow_popGLStates()

void sfRenderWindow_popGLStates | ( | sfRenderWindow * | renderWindow | ) |

Restore the previously saved OpenGL render states and matrices.

See the description of pushGLStates to get a detailed description of these functions.

Parameters

  renderWindow | render window object

## ◆ sfRenderWindow_pushGLStates()

void sfRenderWindow_pushGLStates | ( | sfRenderWindow * | renderWindow | ) |

Save the current OpenGL render states and matrices.

This function can be used when you mix SFML drawing and direct OpenGL rendering. Combined with popGLStates, it ensures that:

- SFML's internal states are not messed up by your OpenGL code
- your OpenGL states are not modified by a call to a SFML function

Note that this function is quite expensive: it saves all the possible OpenGL states and matrices, even the ones you don't care about. Therefore it should be used wisely. It is provided for convenience, but the best results will be achieved if you handle OpenGL states yourself (because you know which states have really changed, and need to be saved and restored). Take a look at the resetGLStates function if you do so.

Parameters

  renderWindow | render window object

## ◆ sfRenderWindow_requestFocus()

void sfRenderWindow_requestFocus | ( | sfRenderWindow * | renderWindow | ) |

Request the current render window to be made the active foreground window.

At any given time, only one window may have the input focus to receive input events such as keystrokes or mouse events. If a window requests focus, it only hints to the operating system, that it would like to be focused. The operating system is free to deny the request. This is not to be confused with sfWindow_setActive().

## ◆ sfRenderWindow_resetGLStates()

void sfRenderWindow_resetGLStates | ( | sfRenderWindow * | renderWindow | ) |

Reset the internal OpenGL states so that the target is ready for drawing.

This function can be used when you mix SFML drawing and direct OpenGL rendering, if you choose not to use pushGLStates/popGLStates. It makes sure that all OpenGL states needed by SFML are set, so that subsequent sfRenderWindow_draw*() calls will work as expected.

Parameters

  renderWindow | render window object

## ◆ sfRenderWindow_setActive()

sfBool sfRenderWindow_setActive | ( | sfRenderWindow * | renderWindow,
|  | sfBool | active )

Activate or deactivate a render window as the current target for rendering.

Parameters

  renderWindow | Render window object
  active | sfTrue to activate, sfFalse to deactivate

Returns
  True if operation was successful, false otherwise

## ◆ sfRenderWindow_setFramerateLimit()

void sfRenderWindow_setFramerateLimit | ( | sfRenderWindow * | renderWindow,
|  | unsigned int | limit )

Limit the framerate to a maximum fixed frequency for a render window.

Parameters

  renderWindow | Render window object
  limit | Framerate limit, in frames per seconds (use 0 to disable limit)

## ◆ sfRenderWindow_setIcon()

void sfRenderWindow_setIcon | ( | sfRenderWindow * | renderWindow,
|  | unsigned int | width,
|  | unsigned int | height,
|  | const sfUint8 * | pixels )

## ◆ sfRenderWindow_setMouseCursor()

void sfRenderWindow_setMouseCursor | ( | sfRenderWindow * | window,
|  | const sfCursor * | cursor )

Set the displayed cursor to a native system cursor.

Upon window creation, the arrow cursor is used by default.

Warning
  The cursor must not be destroyed while in use by the window.
  Features related to Cursor are not supported on iOS and Android.

Parameters

See also
  sfCursor_createFromSystem
  sfCursor_createFromPixels

## ◆ sfRenderWindow_setMouseCursorGrabbed()

void sfRenderWindow_setMouseCursorGrabbed | ( | sfRenderWindow * | renderWindow,
|  | sfBool | grabbed )

Grab or release the mouse cursor.

If set, grabs the mouse cursor inside this window's client area so it may no longer be moved outside its bounds. Note that grabbing is only active while the window has focus and calling this function for fullscreen windows won't have any effect (fullscreen windows always grab the cursor).
