PySide6.QtGui.QPointingDeviceUniqueId¶

class QPointingDeviceUniqueId¶

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

Details

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.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property numericIdᅟ: 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.

isValid()

Access functions:

numericId()

__init__()¶

Constructs an invalid unique pointer ID.

static fromNumericId(id)¶

Parameters:: id – int
Return type:: QPointingDeviceUniqueId

Constructs a unique pointer ID from numeric ID id.

isValid()¶

Return type:: bool

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

numericId()¶

Return type:: int

Getter of property numericIdᅟ .

__ne__(rhs)¶

Parameters:: rhs – QPointingDeviceUniqueId
Return type:: bool

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

__eq__(rhs)¶

Parameters:: rhs – QPointingDeviceUniqueId
Return type:: bool

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