Detailed Description

+ + +The TQPair class is a value-based template class that provides a pair of elements. +

+ + +

TQPair is a TQt implementation of an STL-like pair. It can be used +in your application if the standard pair<> is not available on +your target platforms. +

TQPair<T1, T2> defines a template instance to create a pair of +values that contains two values of type T1 and T2. Please note +that TQPair does not store pointers to the two elements; it holds a +copy of every member. This is why these kinds of classes are +called value based. If you're interested in pointer based +classes see, for example, TQPtrList and TQDict. +

TQPair holds one copy of type T1 and one copy of type T2, but does +not provide iterators to access these elements. Instead, the two +elements (first and second) are public member variables of +the pair. TQPair owns the contained elements. For more relaxed +ownership semantics, see TQPtrCollection and friends which are +pointer-based containers. +

Some classes cannot be used within a TQPair: for example, all +classes derived from TQObject and thus all classes that implement +widgets. Only "values" can be used in a TQPair. To qualify as a +value the class must provide: +

A copy constructor +
An assignment operator +
A constructor that takes no arguments +

Note that C++ defaults to field-by-field assignment operators and +copy constructors if no explicit version is supplied. In many +cases this is sufficient. +

TQPair uses an STL-like syntax to manipulate and address the +objects it contains. See the TQTL + documentation for more information. +

Functions that need to return two values can use a TQPair. +

Member Type Documentation

TQPair::first_type

+The type of the first element in the pair. +

TQPair::second_type

+The type of the second element in the pair. +

Member Function Documentation

TQPair::TQPair () +

+ +

Constructs an empty pair. The first and second elements are +default constructed. + +

TQPair::TQPair ( const T1 & t1, const T2 & t2 ) +

+ +

Constructs a pair and initializes the first element with t1 +and the second element with t2. + +

Related Functions

TQPair qMakePair ( T1 t1, T2 t2 ) +

+ +

This is a template convenience function. It is used to create a +TQPair<> object that contains t1 and t2. + + +
