In this article we will see how we can set tooltip duration to the scroll-able label. By default when we create a label all the text is in the single line and if length of text is greater than label, extra text didn’t show, although with the help of setWordWrap method we can create a multi-line label but still if the text exceeds it will not show in the label. In order to show whole text in a small label we have to make label scroll-able, in order to do this we have to make our own scrollable label class which inherits the QScrollArea class which allows to us to make label scroll-able.
Steps for implementations – 1. Create a new class which inherits QScrollArea 2. Inside the class create vertical layout 3. Create a label and make it multi-line and add it to the layout 5. Over-ride the setText and text method for label 6. Create object of this class inside the main window class and setting text to it 7. Add tooltip to the object with the help of setToolTip method 8. Add tooltip duration to the object with the help of setToolTipDuration method
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)
# 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 " \
" There are so many options provided by Python to develop GUI" \
" 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( 100 , 100 , 150 , 80 )
# setting tool tip
label.setToolTip("It is tool tip")
# setting tool tip duration
label.setToolTipDuration( 1000 )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
