KDToolBox

KDAB's collection of miscellaneous useful C++ classes and stuff.

Generic Tools

• asan_assert_fail Intercept cassert failures with ASAN and print a backtrace.

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.

Other Code Snippets

• Integrating Qt Quick 2 with OpenGL Code for Giuseppe D'Angelo's talk at the Qt World Summit 2015, QtCon 2016, Qt World Summit 2017.

Squish Tools

• kdrunsquish.py Runs squish tests in parallel via the Qt offscreen QPA.
