PyQt5 - 访问组合框的工具提示

在本文中，我们将看到如何访问组合框的工具提示，工具提示基本上是鼠标悬停在组合框小部件上时出现的提示。为了将工具提示设置为组合框，我们使用setToolTip方法。

注意：工具提示仅在鼠标悬停在组合框上而不在下拉视图上时可见

为了访问工具提示，我们使用toolTip方法

Syntax : combo_box.setToolTip()

Argument : It takes no argument

Return : It returns string

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 geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating a combo box widget
        self.combo_box = QComboBox(self)
  
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 30)
  
        # geek list
        geek_list = ["Sayian", "Super Sayian"]
  
        # making it editable
        self.combo_box.setEditable(True)
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # tool tip
        tip = "Sayian Tip"
  
        # setting tool tip to the combo box
        self.combo_box.setToolTip(tip)
  
        # getting the tool tip
        get_tip = self.combo_box.toolTip()
  
        # creating label to show the tool tip
        label = QLabel("Tool tip  : " + get_tip, self)
  
        # setting geometry of the label
        label.setGeometry(200, 100, 200, 30)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
