PyQt5 | How to display decimal values in Progress Bar ?
In this article we will see how to display the decimal values in Progress Bar. We can set the value in progress bar using setValue method but it takes integer as argument. If we try to pass float or double value, it will automatically convert them into integer.
In order to do this we have to do the following :
- Change the maximum range value of progress bar, by default it is from 0 to 100. If we want to show 1 decimal value set it to 100*n here ‘n’ will be 10, if we want to show 2 decimal values set it to 100*n here n will be 100 and so on.
- Set value to progress bar by multiplying it by ‘n’.
- Use format method to display the decimal value.
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 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): # creating progress bar bar = QProgressBar(self) # setting geometry to progress bar bar.setGeometry(200, 150, 200, 30) # setting value of n for 2 decimal values n = 100 # setting maximum value for 2 decimal points bar.setMaximum(100 * n) # value in percentage value = 75.55 # setting the value by multiplying it to 100 bar.setValue(value * n) # displaying the decimal value bar.setFormat("%.02f %%" % value) # setting alignment to centre bar.setAlignment(Qt.AlignCenter) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
