Display ()
~Display ()
int

getWidth () const

Returns the width of the screen measured in points.
int

getHeight () const

Returns the height of the screen measured in points.
ivec2

getSize () const

Returns the size of the Display measured in points.
float

getAspectRatio () const

Returns the Display aspect ratio, which is its width / height.
Area

getBounds () const

Returns the bounding Area of the Display in points, measured relative to primary display's upper-left corner.
ivec2

getSystemCoordinate (const ivec2 &displayRelativeCoordinate) const

Returns the system position (relative to the system's primary display's upper-left corner) of a Display-relative displayRelativeCoordinate . The results are suitable for use with app::Window 's position functions.
int

getBitsPerPixel () const

Returns the bits per pixel for the display. Typically 24 bits.
float

getContentScale () const

Returns the factor which multiplies points to pixels. 2.0f for high-density (Retina) displays; 1.0f for others.
bool

contains (const ivec2 &pt) const

Returns whether the Display 's coordinates contain pt .
std::string

getName () const

Returns the display's name or an empty string if unavailable.

DisplayRef

getMainDisplay ()

Returns the system's primary display.
const std::vector< DisplayRef > &

getDisplays ()

Returns a vector of all displays connected to the system.
DisplayRef

getDisplayForPoint (const ivec2 &pt)

Returns the Display which contains a given point, measured relative to the upper-left corner of the primary display. Returns a NULL DisplayRef on failure.
Area

getSpanningArea ()

Returns the Area which spans all Displays.
