如何在 PyQt5 中将图标设置为窗口?
当我们设计一个 PyQt5 应用程序时,我们会在左上角看到一个图标,默认情况下它看起来像这样:
在本教程中,我们将看到如何根据用户需要更改图标,为此我们使用setWindowIcon()
方法并加载图标QIcon
将使用属于QtGui class
。
Syntax : setWindowIcon(QtGui.QIcon(‘icon.png’))
Argument :bIt takes file name if file is in same folder else file path.
代码 :
# importing the required libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore
from PyQt5 import QtGui
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowIcon(QtGui.QIcon('logo.png'))
# set the title
self.setWindowTitle("Icon")
# setting the geometry of window
self.setGeometry(0, 0, 400, 300)
# creating a label widget
self.label = QLabel("Icon is set", self)
# moving position
self.label.move(100, 100)
# setting up border
self.label.setStyleSheet("border: 1px solid black;")
# show all the widgets
self.show()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
