PyQt5 Scrollable Label – Setting tool tip
In this article we will see how we can set tooltip 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 allow 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 tool tip to the object with the help of setToolTip method
Below is the implementation
Python3
# 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") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
