Sure. In designer add a QLineEdit, right click on it and select "Promote to ...". In "Promoted class name" put the name of your class and in header class what you'd write in the import statement. For example if you have a class called "MyLineEdit" and it's in module "MyWidgets" you'd put: Promoted class name: MyWidgets Header file: MyWidgets Should MyWidgets __init__.py file not include "MyLineEdit" file then you'd do: Promoted class name: MyWidgets Header file: MyWidgets.MyLineEditFile Note that you can also write a plugin in python so your widgets are shown in Qt Designer the same way you'd do in C++.
