PyQt5 – 设置/禁用组合框的框架

在这篇文章中，我们将看到如何设置或禁用组合框的框架。默认情况下，当我们创建一个组合框时，它有一个框架，尽管我们可以改变它。为了设置或禁用框架，我们使用setFrame方法。

语法： combo_box.setFrame(False)

参数： 它以bool作为参数

执行的动作： 它将禁用复选框的框架。

以下是实现方法

# 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", "Legend Geek", "Ultra Legend Geek"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # disabling the frame
        self.combo_box.setFrame(False)
  
        # finding if combo box is having frame or not
        check = self.combo_box.hasFrame()
  
        # creating label to show check
        label = QLabel("Frame = " + str(check), self)
  
        # setting geometry of label
        label.setGeometry(200, 200, 200, 30)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
