Detailed Description

The DummyDisplayDevice class is a pseudo-device class. It stores configuration values passed on the query string and simulates the display behavior.

Member Function Documentation

Bounds pointing::DummyDisplayDevice::getBounds ( Bounds *  defval = 0 )

inlinevirtual

Returns

Bounds of the device expressed in pixels.

Implements pointing::DisplayDevice.

double pointing::DummyDisplayDevice::getRefreshRate ( double *  defval = 0 )

inlinevirtual

Returns

The refresh rate of the device in Hz.

Implements pointing::DisplayDevice.

double pointing::DummyDisplayDevice::getResolution ( double *  hppi = 0, double *  vppi = 0, double *  defval = 0  )

virtual

Computes the pixel density (resolution) of the display device.

It is computed by calculating the diagonal size of the display in pixels and inches and then calculating PPI (Pixels per inch).

Parameters

hppi	Horizontal resolution (OUT)
vppi	Vertical resolution (OUT)
defval	Default value

Returns

PPI resolution

Reimplemented from pointing::DisplayDevice.

Size pointing::DummyDisplayDevice::getSize ( Size *  defval = 0 )

inlinevirtual

Returns

The size of the device (width and height) in mm.

Implements pointing::DisplayDevice.

URI pointing::DummyDisplayDevice::getURI ( bool  expanded = false ) const

virtual

Returns

The corresponding URI of the device.

Parameters

expanded

specifies if additional parameters must be displayed

Implements pointing::DisplayDevice.

void pointing::DummyDisplayDevice::setBounds ( Bounds  b )

inline

setBounds

Parameters

b	is the bounds of the display expressed in pixels.

void pointing::DummyDisplayDevice::setRefreshRate ( int  r )

inline

setRefreshRate

Parameters

r	represents the refresh rate of the display (Hz).

void pointing::DummyDisplayDevice::setResolution ( double  r )

inline

setResolution

Parameters

r	is the pixel density in PPI.

void pointing::DummyDisplayDevice::setSize ( Size  s )

inline

setSize

Parameters

s	is the size of the display expressed in mms.
