KDToolBox
KDAB’s collection of miscellaneous useful C++ classes and stuff.
Tools List
Generic Tools
C++ Tools
- future-backports
Backports of future C++ library components to C++11:
- k20::erase/k20::erase_if - C++20’s uniform container erasure
- DuplicateTracker
A helper class to keep track of “seen” elements, e.g. to avoid processing duplicate elements
in a collection. It transparently uses std::pmr::monotonic_buffer_resource to improve
its memory usage (compared to a ‘plain’ set implementation).
- toContainer
Helper functions to convert a container to another container, using a convenient pipeline style.
- propagate_const
A backport of propagate_const from the C++ Extensions for Library Fundamentals version 3.
Qt Tools
- Ui Watchdog
A header-only tool to break the program when the main-thread event loop is blocked for more
than 300ms.
- Qml Stacktrace Helper
A function for retrieving a QML backtrace with gdb.
- Qml PropertySelector
A QML Item to easily set property values based on a combination of conditions
- Model/View ModelIterator
A set of (template) classes to allow iteratating over QAbstractItemModels using std algorithms
- Model/View SortProxyModel
A QSortFilterProxyModel replacement that just does sorting, but properly signals moves due to sorts.
- Model/View UpdateableModel
A template class to make defining a model that sends proper update signals easy
- Model/View Table to List Proxy
A proxy model flattening a table model into a list model (mainly for Qt Quick 2).
- Functional Sort/Filter Proxy
A QSortFilterProxyModel convenience subclass that allows to set filtering/sorting functions,
removing the need for subclassing.
- TabWindow widget
A tab widget that allows extracting a tab to a new window, like modern web browsers.
- EventFilter
A way for “connecting” a QEvent to lambda with two lines of code.
- MessageHandler
An API to help you intercept the output going through qDebug()/qWarning()/etc.
- QStringTokenizer
A universal, safe, zero-allocation string splitter.
- Signal/Slot Connection Throttlers
An implementation of throttler/debouncer classes for signal/slot connections.
- Single Shot Connect
A header only version of QObject::connect, that establishes a single shot connection.
- Qt Hasher
A header-only hasher object for using Qt types together with unordered_map, unordered_set, etc.
- NotifyGuard
A RAII guard object to make sure object notification signals are properly emitted.
- asan_assert_fail_qt
Intercept Q_ASSERT failures with ASAN and print a backtrace.
- KDSqlDatabaseTransaction
A RAII wrapper for database transactions when using the Qt SQL APIs.
- pointer_cast
Tools to ease migrating from QSharedPointer to std::shared_ptr.
- qt_fmt
Convenience for printing Qt classes through libfmt.
- cmake-project
A replacement for qmake -project, generating a ready-to-use CMakeLists.txt.
- includemocs
A script to add inclusion of moc files to all .cpp files in the project.
- qt6_natvis
Natvis file for Qt6 debugging with Visual Studio and VS Code, with a test project.
- KDStlContainerAdaptor
Classes to ease the transition from Qt containers to the C++ Standard Library containers.
Other Code Snippets
