PyQt5 - 将工具提示设置为 ComboBox 的视图(下拉)部分

在本文中,我们将看到如何将工具提示设置为组合框的下拉部分。当我们将工具提示设置为组合框时,它仅显示在行编辑部分,工具提示对于下拉部分即其视图部分不可见。

句法 :

# getting view part of combo box
view = self.combo_box.view()

# setting tool tip to view object of the combo box
view.setToolTip(tip)

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", "Super Sayian 2", "Super Sayian B"]
  
        # making it editable
        self.combo_box.setEditable(True)
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # tool tip
        tip = "Drop down tool tip"
  
        # getting view part of combo box
        view = self.combo_box.view()
  
        # setting tool tip to view object of the combo box
        view.setToolTip(tip)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
