This document aims at describing which steps are required to migrate PyQt code to PythonQt.

As an example, we will consider the implementation of PythonQt matplotlib backend.

• PyQt should be changed into PythonQt

• QDialog.exec() method isn’t available in PythonQt. Use QDialog.open() as a workaround

• QFontDatabase is not available. There is workaround

• There are no equivalent for pyqtSignature, pyqtProperty

• QString is not available. Python string are mapped with QString.
