In this article we will see how we can get icon of the plot window in the PyQtGraph module. PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. Its primary goals are to provide fast, interactive graphics for displaying data (plots, video, etc.) and second is to provide tools to aid in rapid application development (for example, property trees such as used in Qt Designer).Plot windows consist of two main parts: the Plot Panel containing the actual plotted graphics and the Control Panel. Application Icons are used to depict a particular application in a phone or computer. It is used by different application maker to launch the icon. Tapping or clicking an icon would open up the corresponding application to get it in use. It can be set with the help of setWindowIcon method.
We can create a plot window with the help of command given below
# creating a pyqtgraph plot window window = pg.plot()
In order to do this we use
windowIconmethod with the plot window objectSyntax : window.windowIcon()
Argument : It takes no argument
Return : It returns QIcon object
Below is the implementation
# importing QtGui to use QIcon from PyQt5.QtGui import * # importing pyqtgraph as pg import pyqtgraph as pg # importing QtCore and QtGui from the pyqtgraph module from pyqtgraph.Qt import QtCore, QtGui # importing numpy as np import numpy as np import time # creating a pyqtgraph plot window window = pg.plot() # icon for plot window icon = QIcon("logo.png") # setting icon to the plot window window.setWindowIcon(icon) # setting window geometry # left = 100, top = 100 # width = 600, height = 500 window.setGeometry(100, 100, 600, 500) # title for the plot window title = "neveropen PyQtGraph" # setting window title to plot window window.setWindowTitle(title) # create list for y-axis y1 = [5, 5, 7, 10, 3, 8, 9, 1, 6, 2] # create horizontal list i.e x-axis x = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] # create pyqt5graph bar graph item # with width = 0.6 # with bar colors = green bargraph1 = pg.BarGraphItem(x = x, height = y1, width = 0.6, brush ='g') # add item to plot window # adding bargraph item to the window window.addItem(bargraph1) # getting plot window icon value = window.windowIcon() # printing the value print("Window Icon : " + str(value)) # main method if __name__ == '__main__': # importing system import sys # Start Qt event loop unless running in interactive mode or using if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'): QtGui.QApplication.instance().exec_() |
Output :
Window Icon : PyQt5.QtGui.QIcon object at 0x000002A3CE2FE940
