QPointingDeviceUniqueId#

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

Synopsis#

Functions#

Static functions#

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.

class PySide6.QtGui.QPointingDeviceUniqueId#

PySide6.QtGui.QPointingDeviceUniqueId(QPointingDeviceUniqueId)

Parameters

QPointingDeviceUniqueIdPySide6.QtGui.QPointingDeviceUniqueId

Constructs an invalid unique pointer ID.

static PySide6.QtGui.QPointingDeviceUniqueId.fromNumericId(id)#
Parameters

id – int

Return type

PySide6.QtGui.QPointingDeviceUniqueId

Constructs a unique pointer ID from numeric ID id.

PySide6.QtGui.QPointingDeviceUniqueId.isValid()#
Return type

bool

Returns whether this unique pointer ID is valid, that is, it represents an actual pointer.

PySide6.QtGui.QPointingDeviceUniqueId.numericId()#
Return type

int

This property holds the numeric unique ID of the token represented by a touchpoint.

If the device provides a numeric ID, isValid() returns true, and this property provides the numeric ID; otherwise it is -1.

You should not use the value of this property in portable code, but instead rely on equality to identify pointers.

Parameters

rhsPySide6.QtGui.QPointingDeviceUniqueId

Return type

bool

Parameters

Return type

bool

Returns whether the two unique pointer IDs lhs and rhs identify the same pointer (true) or not (false).
