CardView(CollectionView) in python [duplicate] - python

I am trying to create a scroll area with a vertical layout using pyqt5, and I am putting inside some labels. I know that even if it is a vertical layout it is supposed to scroll horizontally if the text does not fit. But no matter what I try it does not let me scroll.
This is the code I am using:
class window(QMainWindow):
def __init__(self):
super(window, self).__init__()
self.setGeometry(300, 300, 803, 520)
self.init_ui()
def init_ui(self):
self.teacher_box = QScrollArea(self)
self.teacher_box.setGeometry(360, 10, 420, 181)
self.teacher_box.setWidgetResizable(True)
self.teacher_box.setObjectName("teacher_box")
self.teacher_box_widget = QWidget()
self.teacher_box_widget.setGeometry(QtCore.QRect(0, 0, 420, 181))
self.teacher_box_widget.setObjectName("teacher_box_widget")
self.verticalLayout = QVBoxLayout(self.teacher_box_widget)
self.verticalLayout.setObjectName("verticalLayout")
self.teacher_box.setWidget(self.teacher_box_widget)
self.teacher_label = QtWidgets.QLabel(self.teacher_box_widget)
self.teacher_label.setText("This is a new text label that i created using pyqt5's qscrollarea and now the label is going to get outside the boundaries")
self.teacher_label.adjustSize()
self.teacher_label.move(10, 10)
if __name__ == "__main__":
app = QApplication(sys.argv)
win = window()
win.show()
sys.exit(app.exec_())

I hope my question is clear

Since many questions wonder how to use a QScrollArea that many widgets have, I will take the license to explain the various forms in detail and use them as a canonical answer for future readers.
QScrollArea only allows placing a container widget so the other widgets must be placed as children of the container widget.
And to place the widgets as children of another there are 2 possibilities:
1. Use a QLayout:
QLayouts allow you to automate the geometry of the widgets based on the QSizePolicy, strecth, sizeHint, etc. So in that case it's simple: Just set the widgetResizable property to True.
import sys
from PyQt5 import QtWidgets
class Window(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
central_widget = QtWidgets.QWidget()
self.setCentralWidget(central_widget)
scroll_area = QtWidgets.QScrollArea(central_widget)
scroll_area.setGeometry(360, 10, 420, 180)
scroll_area.setWidgetResizable(True)
container = QtWidgets.QWidget()
scroll_area.setWidget(container)
# Set widgets via layout
lay = QtWidgets.QVBoxLayout(container)
lay.setContentsMargins(10, 10, 0, 0)
for letter in "ABCDE":
text = letter * 100
label = QtWidgets.QLabel(text)
lay.addWidget(label)
lay.addStretch()
self.setGeometry(300, 300, 803, 520)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
win = Window()
win.show()
sys.exit(app.exec_())
2. Set the widgets directly without layouts:
In this case you must calculate the minimum geometry that contains the internal widgets and set the size in the container, also you must set the widgetResizable property to False:
import sys
from PyQt5 import QtCore, QtWidgets
class Window(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
central_widget = QtWidgets.QWidget()
self.setCentralWidget(central_widget)
scroll_area = QtWidgets.QScrollArea(central_widget)
scroll_area.setGeometry(360, 10, 420, 180)
scroll_area.setWidgetResizable(False)
container = QtWidgets.QWidget()
scroll_area.setWidget(container)
# calculate geometry
geometry = QtCore.QRect(10, 10, 0, 0)
for letter in "ABCDE":
text = letter * 100
label = QtWidgets.QLabel(text, container)
label.adjustSize()
label.move(geometry.bottomLeft())
geometry |= label.geometry()
geometry.setTopLeft(QtCore.QPoint(0, 0))
container.resize(geometry.size())
self.setGeometry(300, 300, 803, 520)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
win = Window()
win.show()
sys.exit(app.exec_())

PyQt5 add a scrollbar to main window

I know there are already lots of threads opened with this topic, I was trying to follow their recommendations, but I still struggle to achieve this.
Here is my initial code for window:
from PyQt5.QtWidgets import *
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("Python ")
self.setGeometry(100, 100, 600, 400)

emphysemaLabel.move(10, 10)
ggoLabel = QLabel("GGO", self)
ggoLabel.move(10, 300)
condensLabel = QLabel("Condens", self)
condensLabel.move(10, 590)
emphysema_graph_lin = QLabel(self)
emphysema_graph_lin.resize(302, 232)
emphysema_graph_lin.move(10, 50)
emphysema_graph_lin.setStyleSheet("background-color:yellow;")
ggo_graph_lin = QLabel(self)
ggo_graph_lin.resize(302, 232)

An example if what I found useful and working is code found here https://www.pythonguis.com/tutorials/qscrollarea/
I tried to apply it to my code, like this:

emphysemaLabel.move(10, 10)
self.vbox.addWidget(emphysemaLabel)
ggoLabel = QLabel("GGO", self)
ggoLabel.move(10, 300)

App = QApplication(sys.argv)

But it's not working, how should I do it?
Thank you for any advice.
You can add a vertical spacer at the end of the layout using the addStretch() method of the QVBoxLayout object.
And adjust the maximum size to view the scroll working, setMaximumSize().
from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import *
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("Python ")
self.setGeometry(100, 100, 600, 400)
# set maximum size of the QMainWindow
self.setMaximumSize(600, 100)
self.UiComponents()
self.show()
def UiComponents(self):
self.scroll = QScrollArea() # Scroll Area which contains the widgets, set as the centralWidget
self.widget = QWidget() # Widget that contains the collection of Vertical Box
self.vbox = QVBoxLayout() # The Vertical Box that contains the Horizontal Boxes of labels and buttons
emphysemaLabel = QLabel("EMPHYSEMA", self)
emphysemaLabel.move(10, 10)
self.vbox.addWidget(emphysemaLabel)
ggoLabel = QLabel("GGO", self)
ggoLabel.move(10, 300)
self.vbox.addWidget(ggoLabel)
condensLabel = QLabel("Condens", self)
condensLabel.move(10, 590)
self.vbox.addWidget(condensLabel)
emphysema_graph_lin = QLabel(self)
emphysema_graph_lin.resize(302, 232)
emphysema_graph_lin.move(10, 50)
emphysema_graph_lin.setStyleSheet("background-color:yellow;")
self.vbox.addWidget(emphysema_graph_lin)
ggo_graph_lin = QLabel(self)
ggo_graph_lin.resize(302, 232)
ggo_graph_lin.move(10, 340)
ggo_graph_lin.setStyleSheet("background-color:yellow;")
self.vbox.addWidget(ggo_graph_lin)

condens_graph_lin.resize(302, 232)
condens_graph_lin.move(10, 630)
condens_graph_lin.setStyleSheet("background-color:yellow;")
self.vbox.addWidget(condens_graph_lin)
# add a vertical spacer with addStretch() method
self.vbox.addStretch()
self.widget.setLayout(self.vbox)
# Scroll Area Properties
self.scroll.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOn)

PyQt QScrollArea within QScrollArea

I am trying to use multiple horizontal sub QScrollAreas with text and one vertical container QScrollArea. The idea being that the text area in the horizontal sub QScrollAreas will always have equivalent vertical heights and I would like to have one vertical QScrollArea to control the data within them.
The code below shows that the horizontal sub QScrollAreas work, but the vertical QScrollArea doesn't detect that the line edits within the widget inside it don't fit vertically. If I change
scroll.setWidgetResizable(True)
for the vertical QScrollArea to False, the vertical QScrollArea detects the widget inside doesn't fit but I want to be able to scroll all the lineEdits up and down not the parent widget. Also I would like all scrollbars to be always visible. Is this possible?
