Documentation ->if you check this, python documentation will be installed as well.
pip ->this is recommended. you can install other modules with pip easily.

QSizePolicy Fixed example in pyside2

when you set the size policy property of widget to QSizePolicy::Fixed,  the size of widget is fixed. even if the space of layout is changed, the size of widget is fixed. layout management of Qt manages the position and the size of nested widgets. but if any of widgets has fixed size policy, the widget is not handled by layout management. widget has setFixedSize() function. if you use this function, the maximum size and minimum size of widget is set to that value. let's check this behavior from example code. from PySide2 import QtWidgets app = QtWidgets . QApplication([]) window = QtWidgets . QWidget() layout = QtWidgets . QHBoxLayout() fixedSizedButton = QtWidgets . QPushButton( "Fixed Widget" ) print (fixedSizedButton . sizePolicy()) fixedSizedButton . setSizePolicy(QtWidgets . QSizePolicy . Fixed, QtWidgets . QSizePolicy . Fixed) layout . addWidget(fixedSizedButton) window . setLayout(layout) window . show() app . exec_() I created window widg
