PyQt5 - 进度条工具提示

在本文中，我们将看到如何将工具提示设置为进度条。工具提示基本上是当光标悬停在进度条上时出现在屏幕上的提示。工具提示基本上会用来告诉用户百分比或剩余多少时间来完成，为了设置工具提示我们使用setToolTip方法。

Syntax : bar.setToolTip(text)

Argument : It takes string as argument.

Action performed : It will set tool tip to progress bar.

下面是实现。

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting background color to window
        # self.setStyleSheet("background-color : yellow")
  
        # 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 progress bar
        bar = QProgressBar(self)
  
        # setting geometry to progress bar
        bar.setGeometry(200, 100, 200, 30)
  
        # setting the value
        value = 70
        bar.setValue(value)
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # setting tool tip
        bar.setToolTip("Percentage is currently at " + str(value))
  
  
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
