class QgsScreenProperties
{

Stores properties relating to a screen.
This class is designed to be a publicly constructible, copyable store
for the properties available from a QScreen object.

public:

Constructor for invalid properties.

Constructor for QgsScreenProperties, copying properties from the
specified ``screen``.

Returns ``True`` if the properties are valid.

double devicePixelRatio() const;
%Docstring
Returns the ratio between physical pixels and device-independent pixels
for the screen.
This property holds the screen's ratio between physical pixels and
device-independent pixels.
Common values are 1.0 on normal displays and 2.0 on "retina" displays.
Higher values are also possible.
.. seealso:: :py:func:`setDevicePixelRatio`

%Docstring
Sets the ``ratio`` between physical pixels and device-independent pixels
for the screen.
This property holds the screen's ratio between physical pixels and
device-independent pixels.
Common values are 1.0 on normal displays and 2.0 on "retina" displays.
Higher values are also possible.
.. seealso:: :py:func:`devicePixelRatio`
%End
double physicalDpi() const;
%Docstring
This property holds the number of physical dots or pixels per inch.
This value represents the pixel density on the screen's display.
Depending on what information the underlying system provides the value
might not be entirely accurate.
.. note::
Physical DPI is expressed in device-independent dots. Multiply by :py:func:`~QgsScreenProperties.devicePixelRatio` to get
device-dependent density.
