In this article we will see how we can set tooltip duration to the label part of scroll label, when know we can make scrollable label with the help of inheriting a scroll class and making label in it, but when we set tooltip to the class object tooltip is set to the whole widget i.e label and the scroll bar as well.
In order to add tooltip and its duration to the label part, we have to override the function of the object.
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. Over-ride setToolTip method and add tool tip to the label
7. Over-ride the setToolTipDuration method add duration the label
8. Create object of this class inside the main window class and setting text to it
9. Add tool tip to the object with the help ofsetToolTip
method
10. Add tool tip duration to the object with the help ofsetToolTipDuration
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
# setToolTip method
def setToolTip( self , p_str):
# setting tool tip to the label
self .label.setToolTip(p_str)
# setToolTipDuration method
def setToolTipDuration( self , p_int):
# setting tool tip duration to the label
self .label.setToolTipDuration(p_int)
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 ())
|
Output :
This tool tip will disappear after 1000 millisecond
