• v2.5.0
  • LayoutSaver: New LayoutSaver::addWindowToSave(), to save and restore individual windows.
    Call it once per window, passing a main window, a floating window, or a dock widget to mean
    whichever window it currently sits in. Not calling it saves everything, as before.
    Restoring needs no counterpart call: a layout saved this way describes only the windows you
    picked, so it leaves every other window alone.
    Use this instead of affinities when you want to save one top-level window. Affinities filter
    dock widgets, and a main window's layout is saved whole or not at all, so an affinity set
    that cuts through a main window produces a layout that cannot be restored (issue #723).
    Such a save is now refused, with an error message naming both sides, rather than silently
    writing a broken file.
  • LayoutSaver: New RestoreOption_CloseUnknownDockWidgets. A dock widget docked in a main
    window being restored, but absent from the saved layout, is closed instead of floated.
  • LayoutSaver: A dock widget with no affinities is no longer dropped from its group when
    saving with an affinity filter. setAffinityNames() always documented that anything with an
    empty affinity is saved regardless of the filter, and every other code path honoured it.
  • Fix MDI not honouring initial size property
  • qtquick: Support setting floating window flags from QML
  • qtquick: Support dark mode
  • qtquick: In MDI, fix random splitters getting highlighted
  • ViewFactory: createGroup()/createTitleBar()/createTabBar()/createFloatingWindow() now have
    new overloads which also receive the userType() of the DockWidget that's initially covered
    by the created view (see DockWidget::setUserType()). Override these instead of the existing
    ones if you want to pick a different Group/TitleBar/TabBar/FloatingWindow sub-class
    depending on the dock widget's userType.
    • Potential source break: if your own ViewFactory subclass already overrides
      createGroup()/createTitleBar()/createTabBar()/createFloatingWindow() and you build with
      -Woverloaded-virtual (or -Wall -Wextra, which some compilers include it in), you'll now
      get a "hidden virtual function" warning/error, since your existing override hides the new
      overload. Workaround: add a using-declaration for the affected function(s) to your
      ViewFactory subclass, for example:
      class MyViewFactory : public KDDockWidgets::QtWidgets::ViewFactory
      {
      public:
      using KDDockWidgets::QtWidgets::ViewFactory::createTitleBar; // add this line
      Core::View *createTitleBar(Core::TitleBar *, Core::View *parent) const override;
      ...
      };
      This is a compile-time-only concern; code that doesn't enable -Woverloaded-virtual (or
      doesn't treat warnings as errors) is unaffected and needs no changes.
