Qt QML Integrated GUI for Robots

This package is built on the top of Qt5 and its python binding called PyQt5.

sudo apt install \
    python-pyqt5.qtquick \
    qtdeclarative5-controls-plugin \
    qml-module-qtquick-dialogs

1. Create GUI using QML. (See example in qml directory)

2. Load QML in RQT Plugin

   rqt_qml $(rospack find rqt_qml)/qml/simple.qml

The launch file additionally defines LIBOVERLAY_SCROLLBAR environment variable and set it to 0 to avoid QT GTK+ bug on Ubuntu. If you do not have any scrollbars in your QML graphical interface then the variable can be omitted.

To add your own QML plugins (either written in Python or C++) use <rqt_qml> tag in export section of a package.xml in your package, for instance:

  <export>
    <rqt_qml plugins="${prefix}/my_qml_plugins_dir"/>
  </export>

If a relative path supplied to plugins attribute, it will be treated as relative to Qt plugins directory, for example:
