PyQt5 - 访问状态栏的大小

在本文中，我们将了解如何访问状态栏的大小。我们知道我们可以使用setFizedSize方法和状态栏对象来设置状态栏的大小，为了访问状态栏的大小，我们将使用size方法和它的对象。

Notes:
-> If size of status bar is not set it will return minimum size.
-> If fixed size of status bar is set it will return fixed size.
-> If minimum size of status bar is set it will return minimum size.
-> If maximum size of status bar is set it will return minimum size.

Syntax : self.statusBar().size()

Argument : It takes no argument.

Return : It returns QSize object.

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
        self.statusBar().setStyleSheet("border :3px solid black;")
  
        # setting fixed size
        self.statusBar().setFixedSize(400, 60)
  
        # getting size
        size = self.statusBar().size()
  
        # printing the size
        print(size)
  
        # 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 ：

PyQt5.QtCore.QSize(400, 60)
