PyQt5 - 设置和访问状态栏的描述

在本文中，我们将看到如何设置和访问状态栏的描述。为了设置描述，我们使用statusBar().setAccessibleDescription()方法和访问我们使用self.statusBar().accessibleDescription()方法。

状态栏的描述是状态栏的详细信息，设置描述有助于更好地理解后端的详细信息。

Syntax :
self.statusBar().setAccessibleDescription(details)
self.statusBar().accessibleDescription()

Argument :
self.statusBar().setAccessibleDescription(details) takes string as argument.
self.statusBar().accessibleDescription() takes no argument.

Return :
self.statusBar().setAccessibleDescription(details) returns no value.
self.statusBar().accessibleDescription() returns string.

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 to status bar
        self.statusBar().setStyleSheet("border :3px solid black;")
  
        # setting description to status bar
        self.statusBar().setAccessibleDescription(
                 "this is description of status bar")
  
  
        # creating a label widget to show deciption
        self.label_1 = QLabel( self)
  
        # moving position
        self.label_1.move(100, 100)
  
        # setting up the border
        self.label_1.setStyleSheet("border :1px solid blue;")
  
        # accessing the description
        data = self.statusBar().accessibleDescription()
  
        # setting text to label
        self.label_1.setText(data)
  
        # 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())
