We want to present a widget which can be moved and at which it is possible to change the sizes. This widget can serve as the container for other widgets, such as to QLabel, QTableWidget and so on. This widget is used by autors already in several projects. We hope it we will to you it is useful
  
mainwindow.h<br /> mainwindow.cpp

There are two version of the widget: original,  written in C++ and  translated to Python with PyQt.
  
tcontainer.h<br />

Python (PyQt) version is accessible  by  https://github.com/korabelnikov/moveable-and-resize-qt-widget-on-python feel free to use and improve it.

We want to present a widget which can be moved and at which it is possible to change the sizes. This widget can serve as the container for other widgets, such as to QLabel, QTableWidget and so on. This widget is used by autors already in several projects. We hope it we will to you it is useful

There are two version of the widget: original, written in C++ and translated to Python with PyQt.

Python (PyQt) version is accessible by https://github.com/korabelnikov/moveable-and-resize-qt-widget-on-python feel free to use and improve it.
