PyQt5 - 设置状态栏的最大尺寸

我们知道默认情况下，当我们调整窗口大小时，状态栏也会调整大小。在本文中，我们将看到如何设置状态栏的最大尺寸，即当我们扩展窗口时，状态栏不应超出此尺寸。

为了做到这一点，我们将使用setMaximumSize方法和状态栏对象。

Syntax : self.statusBar().setMaximumSize(width, height)

Argument : It takes two argument, both integer which refers width and height.

Action performed : It sets the maximum size to status bar.

代码 ：

from PyQt5.QtCore import * 
from PyQt5.QtGui import * 
from PyQt5.QtWidgets import * 
import sys
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
        # set the title
        self.setWindowTitle("Python")
  
        # setting  the geometry of window
        self.setGeometry(60, 60, 600, 400)
  
        # setting status bar message
        self.statusBar().showMessage("This is status bar")
  
        # setting  border and padding with different sizes
        self.statusBar().setStyleSheet("border :3px solid black;")
  
        # setting maximum size
        self.statusBar().setMaximumSize(400, 100)
  
        # creating a label widget
        self.label_1 = QLabel("status bar", self)
  
        # moving position
        self.label_1.move(100, 100)
  
        # setting up the border
        self.label_1.setStyleSheet("border :1px solid blue;")
  
        # resizing label
        self.label_1.adjustSize()
  
        # 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 ：
