PyQt5 – Getting text of scrollable label

In this article we will see how we can get the text of the scroll-able label, we can create a scroll-able label with the help of making new class which inherits scroll area class but the problem arises the new class can only set the text we can’t get the text as it is scroll-able label class object not the normal label object.

In order to retrieve the text from scrollable label, do the following –

1. Create a scroll-able label class which inherits QScrollArea
2. Add layout and add label to the label
3. Make set text function which adds text to the label
4. Create a text function which returns the content of the label

Scroll Label Class Syntax :

class ScrollLabel(QScrollArea):

    # constructor
    def __init__(self, *args, **kwargs):
        QScrollArea.__init__(self, *args, **kwargs)

        # making widget resizable
        self.setWidgetResizable(True)

        # making qwidget object
        content = QWidget(self)
        self.setWidget(content)

        # vertical box layout
        lay = QVBoxLayout(content)

        # creating label
        self.label = QLabel(content)

        # setting alignment to the text
        self.label.setAlignment(Qt.AlignLeft | Qt.AlignTop)

        # making label multi-line
        self.label.setWordWrap(True)

        # adding label to the layout
        lay.addWidget(self.label)

    # the setText method
    def setText(self, text):
        # setting text to the label
        self.label.setText(text)

    # getting text method
    def text(self):

        # getting text of the label
        get_text = self.label.text()

        # return the text
        return get_text

Below is the implementation






# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
# class for scrollable label
class ScrollLabel(QScrollArea):
  
    # constructor
    def __init__(self, *args, **kwargs):
        QScrollArea.__init__(self, *args, **kwargs)
  
        # making widget resizable
        self.setWidgetResizable(True)
  
        # making qwidget object
        content = QWidget(self)
        self.setWidget(content)
  
        # vertical box layout
        lay = QVBoxLayout(content)
  
        # creating label
        self.label = QLabel(content)
  
        # setting alignment to the text
        self.label.setAlignment(Qt.AlignLeft | Qt.AlignTop)
  
        # making label multi-line
        self.label.setWordWrap(True)
  
        # adding label to the layout
        lay.addWidget(self.label)
  
    # the setText method
    def setText(self, text):
        # setting text to the label
        self.label.setText(text)
  
    # getting text method
    def text(self):
  
        # getting text of the label
        get_text = self.label.text()
  
        # return the text
        return get_text
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
        # text to show in label
        text = "There are so many options provided by Python to develop GUI "
  
        # creating scroll label
        label = ScrollLabel(self)
  
        # setting text to the label
        label.setText(text)
  
        # setting geometry
        label.setGeometry(10, 100, 100, 80)
  
        get_text = label.text()
  
        # creating another label to show the text
        result = QLabel(get_text, self)
  
        # setting geometry to the label
        result.setGeometry(150, 100, 400, 40)
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())
