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

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.

PySide6.QtGui.QPointingDeviceUniqueId(QPointingDeviceUniqueId)
- Parameters
QPointingDeviceUniqueId –
PySide6.QtGui.QPointingDeviceUniqueId
Constructs an invalid unique pointer ID.
- static PySide6.QtGui.QPointingDeviceUniqueId.fromNumericId(id)#
- Parameters
id – int
- Return type
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.

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

- Parameters
- Return type
bool
