example of QSizePolicy Maximum in PySide2

-
if you set the size policy property of widget to Maximum, the result of sizeHint() come to be maximum size of widget. it means that the size of widget cannot be larger than sizeHint().

from PySide2 import QtWidgets

app = QtWidgets.QApplication([])

window = QtWidgets.QWidget()
layout = QtWidgets.QHBoxLayout()
MaximumButton = QtWidgets.QPushButton("Maximum Widget")

MaximumButton.setSizePolicy(QtWidgets.QSizePolicy.Maximum , QtWidgets.QSizePolicy.Maximum )

layout.addWidget(MaximumButton)
window.setLayout(layout)
window.show()

app.exec_()




QPushButton's minimumSizeHint() function is implemented. so, even if we didn't set the minimum size, the size of button cannot be decreased more than first image.

and, when I increased the size of window, the size of button is not increased according to the size of window. because the size policy is Maximum that means the size of button cannot be larger than sizeHint(). as the result, the button's size of first image is same to second.

Qt Quick Control module has ApplicationWindow object that has menubar, toolbar, footer and contents areas. in this page, I will introduce how to make menubar. first of all, we need application engine in python. so you can learn the way how to make the application object in python from  how to use Qt Quick Controls in PySdie2 we need simple window like below. import QtQuick 2.13 import QtQuick.Controls 2.13 ApplicationWindow { visible: true width: 720 height: 480 title: "simple window" } WindowApplication is invisible by default. so, we should set the visibility to true. and the properties that I used above are derived from QML Item object. ApplicationWindow has its own properties like below. activeFocusControl : Control background : Item contentData : list contentItem : Item font : font footer : Item header : Item locale : Locale menuBar : Item palette : palette we will focus on only menubar property of them in this pa

What is QML? QML is UI programming language. it is some like the structure of JSON format. QML is supported by QtQML module. In other words, it is based in Qt framework. QtQuick module includes QtQML module. and QtQuick includes visual components, model-view support, animation framework and other many components to build UI. What is strength of QML? QML is derived from Qt. using QML means using Qt. Qt is cross-platform framework. so, once you are familiar with Qt, you can make desktop, mobile(andorid and ios) and embedded GUI application with only Qt knowledge. and you can choose what you use for back-end with c++ and python. when learning new programming, it would be best way to print "Hello World". so, I will show you how to print "Hello World" with QML and Python. first of all, you should make .qml file. I made View.qml file for example. and then, just type like below code. //View.qml import QtQuick 2.0 Rectangle { width: 200 height

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
