Member Function Documentation

physicalToLogical() [1/2]

Rectangle<int> Displays::physicalToLogical ( Rectangle< int >  , const Display *  useScaleFactorOfDisplay = nullptr  ) const

noexcept

Converts a Rectangle from physical to logical pixels.

If useScaleFactorOfDisplay is not null then its scale factor will be used for the conversion regardless of the display that the Rectangle to be converted is on.

logicalToPhysical() [1/2]

Rectangle<int> Displays::logicalToPhysical ( Rectangle< int >  , const Display *  useScaleFactorOfDisplay = nullptr  ) const

noexcept

Converts a Rectangle from logical to physical pixels.

If useScaleFactorOfDisplay is not null then its scale factor will be used for the conversion regardless of the display that the Rectangle to be converted is on.

physicalToLogical() [2/2]

template<typename ValueType >

Point<ValueType> Displays::physicalToLogical ( Point< ValueType >  , const Display *  useScaleFactorOfDisplay = nullptr  ) const

noexcept

Converts a Point from physical to logical pixels.

logicalToPhysical() [2/2]

template<typename ValueType >

Point<ValueType> Displays::logicalToPhysical ( Point< ValueType >  , const Display *  useScaleFactorOfDisplay = nullptr  ) const

noexcept

Converts a Point from logical to physical pixels.

findDisplayForRect()

const Display& Displays::findDisplayForRect ( Rectangle< int >  , bool  isPhysical = false  ) const

noexcept

Returns the Display object representing the display containing a given Rectangle (either in logical or physical pixels).

If the Rectangle lies outside all the displays then the nearest one will be returned.

findDisplayForPoint()

const Display& Displays::findDisplayForPoint ( Point< int >  , bool  isPhysical = false  ) const

noexcept

Returns the Display object representing the display containing a given Point (either in logical or physical pixels).

If the Point lies outside all the displays then the nearest one will be returned.

getMainDisplay()

const Display& Displays::getMainDisplay ( ) const

noexcept

Returns the Display object representing the display acting as the user's main screen.

getRectangleList()

RectangleList<int> Displays::getRectangleList

(

bool

userAreasOnly

)

const

Returns a RectangleList made up of all the displays in LOGICAL pixels.

getTotalBounds()

Rectangle<int> Displays::getTotalBounds

(

bool

userAreasOnly

)

const

Returns the smallest bounding box which contains all the displays in LOGICAL pixels.
