%description
dtk is a plugin/factory-based scientific software platform from Inria,
originally written against Qt5. Upstream dtk has been dormant since
2021 and the public repository has no Qt6 branch.

This package is a Qt6 port maintained as a downstream fork against the
1.7.1 upstream tag. It rebuilds the subset of dtk that medInria 5.x
actually depends on: dtkCore, dtkCoreSupport, dtkGuiSupport,
dtkMathSupport, dtkVrSupport, dtkLog, dtkMath, dtkWidgets. The
following upstream components are excluded because they are either
unused by all known downstream consumers or carry deep Qt5-private-API
coupling that would require significant rewrite for marginal benefit:

  - dtkMeta (Qt5 private QMetaType API; rewritten in Qt6)
  - dtkAbstractDataComposite (QList/QVector overload duplication after
    Qt6 aliased the two types)
  - dtkComposer / dtkComposerSupport (visual node-graph editor; not
    used by medInria)
  - dtkDistributed (HPC cluster/MPI front-end; not used by medInria)
  - dtkScript / dtkContainerSupport / dtkPlotSupport (unused)
  - SIP/SWIG Python wrappers

* Tue May 19 2026 Morgan Hough <morgan.hough@gmail.com> - 1.7.1-1
- Initial dtk-qt6 fork — Qt6 port of upstream dtk 1.7.1, trimmed to
  the subset medInria 5.x consumes. Source at
  https://gitlab.com/morgan.hough/dtk-qt6 (qt6-port branch).
- Trims: dtkMeta, dtkAbstractDataComposite, dtkComposer, dtkDistributed,
  dtkScript, SIP/SWIG wrappers
- Mechanical Qt5->Qt6 ports across cmake (Qt5:: -> Qt6::,
  qt5_add_resources -> qt6_add_resources, cmake_minimum 3.2 -> 3.16)
  and source (QRegExp -> QRegularExpression, QFontMetrics::width ->
  horizontalAdvance, QLayout::margin -> contentsMargins,
  QApplication::globalStrut removed, QDesktopWidget -> QScreen,
  Qt::Modifier + -> bitwise |, qSort -> std::sort, qLess -> std::less,
  qVariantFromValue -> QVariant::fromValue, QRegExpValidator ->
  QRegularExpressionValidator, QHash::insertMulti -> QMultiHash,
  QAtomicInt::load/store -> loadRelaxed/storeRelaxed,
  QString::SkipEmptyParts -> Qt::SkipEmptyParts, QLinkedList -> QList,
  endl -> Qt::endl, return 0 -> Qt::Orientations{},
  setFilterRegExp -> setFilterRegularExpression)
- Latent bug fixed: dtkDistributedArray::range() called this->get()
  (no such method) - replaced with this->range() recursive call
