#[repr(C)]pub struct QPairOfQAccessibleInterfaceQFlagsRelationFlag { /* private fields */ }
Expand description
The QPair class is a template class that stores a pair of items.
C++ class: QPair<QAccessibleInterface*, QFlags<QAccessible::RelationFlag>>
.
The QPair class is a template class that stores a pair of items.
QPair<T1, T2> can be used in your application if the STL pair
type is not available. It stores one value of type T1 and one value of type T2. It can be used as a return value for a function that needs to return two values, or as the value type of a generic container.
Here's an example of a QPair that stores one QString and one double
value:
The components are accessible as public data members called first and second. For example:
pair.first = “pi”; pair.second = 3.14159265358979323846;
Note, however, that it is almost always preferable to define a small struct to hold the result of a function with multiple return values. A struct trivially generalizes to more than two values, and allows more descriptive member names than first
and second
:
struct Variable { QString name; double value; }; Variable v; v.name = “pi”; v.value = 3.14159265358979323846;
The advent of C++11 automatic variable type deduction (auto
) shifts the emphasis from the type name to the name of functions and members. Thus, QPair, like std::pair
and std::tuple
, is mostly useful in generic (template) code, where defining a dedicated type is not possible.
QPair's template data types (T1 and T2) must be assignable data types. You cannot, for example, store a QWidget as a value; instead, store a QWidget *. A few functions have additional requirements; these requirements are documented on a per-function basis.
