PyQt5 - 为 ComboBox 的不同项目设置不同的工具提示

在本文中，我们将看到如何为组合框的不同项目设置不同的工具提示。我们可以借助setToolTip方法将工具提示设置为组合框，而要将工具提示设置为视图部分，我们必须通过此方法使用视图对象。下面是单个项目工具提示的外观表示。

为了做到这一点，我们必须使用以下方法

combo_box.setItemData(index, tool_tip_text, QtCore.Qt.ToolTipRole)

Here index is the index of the item
tool_tip_text is the string which show as tool 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 object
        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"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # setting tool tip to each item
        self.combo_box.setItemData(0, "This is a tooltip for item[0]", QtCore.Qt.ToolTipRole)
        self.combo_box.setItemData(1, "This is a tooltip for item[1]", QtCore.Qt.ToolTipRole)
        self.combo_box.setItemData(2, "This is a tooltip for item[2]", QtCore.Qt.ToolTipRole)
        self.combo_box.setItemData(3, "This is a tooltip for item[3]", QtCore.Qt.ToolTipRole)
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())

输出 ：
