KDDockWidgets

KDDockWidgets is a KDAB effort to provide an advanced docking system for Qt.

Throughout the years KDAB contributed and funded bug fixes and features to QDockWidget. Sadly, this was very painful. Each bug fix or feature took many days of implementation, and an equal number of days just to fix dozens of regressions.

QDockWidget mixes GUI code with logic with state, making it very hard to move forward with new features. Furthermore, our customers were getting more creative with their requests, so it was clear we needed a better docking framework.

Features

  • Provide advanced docking that QDockWidgets doesn't support

    • Nesting dock widgets in a floating window and docking that group back to main window
    • Docking to any main window, not only to the parent main window
    • Docking to center of main window, or simply removing the concept of "central widget"
    • Main window supporting detachable tabs in center widget
    • Detaching arbitrary tabs from a tab bar into a dock area
    • Exposing inner helper widgets so the user can customize them or provide his own
      • Customize tab widgets
      • Customize title bars
      • Customize window frames
  • Clean codebase

    • Not mixing GUI with state with logic with animations
    • Unit-test everything, even the GUI and DnD operations (140 tests currently)
    • Fuzzer for doing random testing

Roadmap

  • Different forms of docking indicators (through plugins)
  • QtQuick support

Trying out the demo

Open a terminal capable of building Qt5 applications (Should have cmake, ninja, compiler, Qt, etc in PATH).

Feel free to adapt the instructions to suit your cmake generator and operating system. Build and install the KDDockWidgets framework:

$ cmake -G Ninja -DCMAKE_INSTALL_PREFIX=/path/where/to/install ../path/to/kddockwidgets
$ make
$ make install

Now build and run the example:

$ cd path/to/kddockwidgets/examples/dockwidgets/
$ cmake -DCMAKE_PREFIX_PATH=/path/where/to/install
$ make
$ ./kddockwidgets_example
