PyQt5 - 状态栏的访问工具提示持续时间

我们知道在状态栏对象的帮助下，我们可以设置工具提示和工具提示持续时间。在本文中，我们将了解如何访问工具提示持续时间。为此，我们将对状态栏对象使用toolTipDuration方法。

Syntax : self.statusBar().toolTipDuration()

Argument : It takes no argument.

Return : It returns integer which refer to milliseconds.

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 tool tip for status bar
        self.statusBar().setToolTip("Hello ! from status bar")
  
        # setting tool tip duration
        self.statusBar().setToolTipDuration(500)
  
        # accessing tool tip duration
        t = str(self.statusBar().toolTipDuration())
  
        # creating a label widget
        self.label_1 = QLabel("time in ms = " + t, 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 ：
