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.

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:
__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:

rhsQPointingDeviceUniqueId

Return type:

bool

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

__eq__(rhs)#
Parameters:

rhsQPointingDeviceUniqueId

Return type:

bool

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