QList to QSet

And to save this QList<Variant> to my Settings I use the following code: QVariant list; list.setValue (variantList); //saveSession is my QSettings object saveSession.setValue (MyList, list); The QList is correctly saved to my INI file as I can see (comma seperated list of my ints) But the function crashes on exit See also toList() and QList::toSet(). QSet::iterator QSet:: insert (const T &value) Inserts item value into the set, if value isn't already in the set, and returns an iterator pointing at the inserted item. See also operator<<(), remove(), and contains(). QSet < T > &QSet:: intersect (const QSet < T > &other ordered - qlist to qset . Qt foreach loop ordering vs. for loop for QList (3) When iterating through a QList<T> with a foreach loop, in the tests I conducted the items are returned in the same order as they are with a standard for loop. My question is, will the foreach always return items in numerical order by index like.

qt - Save QList<int> to QSettings - Stack Overflo

We expect QList to have a O(n) complexity for containment testing and QSet potential O(1) complexity for containment testing. Searching through an unsorted sequential container such as QList requires examing every single element and results in a runtime complexity O(n). On the other hand, QSet is a hash-table based container. Unlike sequential containers, sets do not keep elements in the order they were inserted. This has some advantages. For example, containment testing is faster for sets. Since QSet doesn't allow duplicates, the resulting QSet might be smaller than the list, because QList can contain duplicates. Example: QStringList list; list < < Julia < < Mike < < Mike < < Julia < < Julia ; QSet < QString > set = QSet < QString > :: fromList(list); set . contains ( Julia ); // returns true set . contains ( Mike ); // returns true set . size (); // returns SOLVED Here are final tests and they all work fine. There is a small issue in debugging these prints they get out of sequence and if the test exit is in wrong place code get missed. Thanks for all the wonderful support received in resolving this

In this tutorial, we will learn about ModelView with QListView and QStringListModel. In this example, we'll use Qt Gui application with QDialog: Qt's MVC may not be the same as the conventional MVC. If the view and the controller objects are combined, the result is the model/view architecture. This still separates the way that data is stored from. However, I can explicitely reinterpret-cast the QList as follows: template <typename T> inline QList<const T *> &constList (const QList<T *> &list) { return (QList<const T *> &)list; } This enables me to use the constList template function to cast any QList<T *> into a QList<const T *>, as in. f (constList (QList<T *> ())) We populate the list widget with the method addItems(QStringList). Once the items have been created, we enable checking/unchecking of the items with the flag Qt::ItemIsUserCheckable. This flag is all that is necessary to make items checkable. We also set the default state of the items to Qt::Unchecked

Unlike STL-style iterators (covered below ), Java-style iterators point between items rather than directly at items To create a list, use the square brackets ([ ]) in Python. Convert Python List to Set To convert list to set in Python, use the set () function. The set () function in Python is an inbuilt function that creates a set

QSet Class Qt Core 5

Example. The QList class is a template class that provides lists. It stores items in a list that provides fast index-based access and index-based insertions and removals. To insert items into the list, you can use operator<<(), insert(), append() or prepend().For example Given a list (ArrayList or LinkedList), convert it into a set (HashSet or TreeSet) of strings in Java. Method 1 (Simple) We simply create an list. We traverse the given set and one by one add elements to the list Since both Set and List are extend the Collection, the conversion is quite straightforward. It's just pass a List into Set constructor or vice verse. Convert List to Set Set set = new HashSet (list) Hi guys! I wonder if i can somehow save a QList using QSettings. So far all my attempts did fail. My last hope was QVariant but i only get a C2440 cannot convert 'QList' to 'QVariant' if i try QVariant list = myList;. Did find some examples out there t..

QStringList ist defacto QList<QString> und nicht QList<int> und auch nicht QList<int>* . Damit passt die Fehlermeldung unten eigentlich nicht zu deinen Angaben. @steevie said in int Daten aus der Containerklasse QSet in ein ListWidget ausgeben: cpp:129: Fehler:cannot convert 'QList<int>' to 'QList<int>*' in assignmen Lists and sets in Python both contain groups of items, but there are important differences between the two. In particular, sets are useful for performing a wide range of operations such as unions and intersections, while lists have fewer mathematical operations but are useful for searching for specific items - especially with duplicates - and organizing data Bing Places for Business is a Bing portal that enables local business owners add a listing for their business on Bing.

ordered - qlist to qset - Code Example

  1. QList has both Java-style iterators and STL-style iterators. The Java-style iterators are more high-level and easier to use than the STL-style iterators; on the other hand, they are slightly less efficient. The QListIterator class provides a Java-style const iterator for QList. QListIterator<T> allows us to iterate over a QList<T>. If we want to modify the list as we iterate over it, use.
  2. A hash set is either immutable or mutable; mutable hash sets retain their elements either strongly or weakly. Like operations on immutable hash tables, constant time hash set operations actually require O (log N) time for a set of size N. A hash set can be used as a stream (see Streams) and thus as a single-valued sequence (see Sequences). The elements of the set serve as elements of the stream or sequence. If an element is added to or removed from the hash set during iteration, then.
  3. Now we can use the simpler getForObject() method to get the list of employees: EmployeeList response = restTemplate.getForObject( http://localhost:8080/employees, EmployeeList.class); List<Employee> employees = response.getEmployees(); This code is much simpler but requires an additional wrapper object. 4
