Chapter 9, Designing a GUI for a Robot Using Qt and Python

1. Qt and GTK.
2. Both bindings are almost the same, only difference is in the name. The PyQt license is GPL and PySide comes with LGPL. Also, PySide is having much documentation about its APIs.
3. We can use Py UI compiler named pyuic.
4. Qt slots are functions in a program that can be triggered by Qt signal. For example, clicked is a signal that can invoke a function named hello().
5. Rqt is one of the useful GUI tool in ROS. We can create rqt plugins and can insert in the rqt gui. There are existing plugins to do visualization, debugging, and so on in rqt.
