PyQt5 – 如何以最大化格式打开窗口？

在本文中，我们将了解如何使窗口以最大化格式打开，这指的是全屏显示窗口。我们可以通过使用属于QWidget class的showMaximized方法来做到这一点。

Syntax : self.showMaximized()

Argument : It takes no argument.

Action performed It will open the window in full screen format.

代码 ：

# importing libraries
from PyQt5.QtWidgets import * 
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 label
        label = QLabel("Label", self)
  
        # setting geometry to label
        label.setGeometry(100, 100, 120, 40)
  
        # adding border to label
        label.setStyleSheet("border : 2px solid black")
  
        # opening window in maximized size
        self.showMaximized()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
