QPointingDeviceUniqueId¶

QPointingDeviceUniqueId identifies a unique object, such as a tagged token or stylus, which is used with a pointing device. More…

Synopsis¶

Functions¶

def __eq__ (, rhs)
def __ne__ (, rhs)
def isValid ()
def numericId ()

Static functions¶

def fromNumericId (id)

Detailed Description¶

QPointingDeviceUniqueIds can be compared for equality, and can be used as keys in a QHash . You get access to the numerical ID via numericId() , if the device supports such IDs. For future extensions, though, you should not use that function, but compare objects of this type using the equality operator.

This class is a thin wrapper around an integer ID. You pass it into and out of functions by value.

This type actively prevents you from holding it in a QList , because doing so would be very inefficient. Use a QVector instead, which has the same API as QList , but more efficient storage.
