PyQt5 - 在 ComboBox 中设置项目图标的图标大小

在本文中,我们将了解如何将图标大小设置为组合框的项目。默认情况下,组合框中的图标没有设置图标,虽然我们可以借助setItemIcon方法为每个项目设置图标,但有时需要调整图标大小。

为了改变项目图标的图标大小,我们将使用setIconSize方法。

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, 120, 30)
  
        # geek list
        geek_list = ["Geek", "Geeky Geek"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # creating editable combo box
        self.combo_box.setEditable(True)
  
        # index
        index = 0
  
        # icon
        icon = QIcon('logo.png')
  
        # adding icon to the given index
        self.combo_box.setItemIcon(index, icon)
  
        # size
        size = QSize(10, 10)
  
        # setting icon size
        self.combo_box.setIconSize(size)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
