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
Scrollable Label Class Syntax :
class ScrollableLabel(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
Python3
