PyQt5 – 检查组合框是否可编辑
在这篇文章中,我们将看到如何知道一个组合框是否是可编辑的。可编辑的组合框是指用户可以通过输入来改变它的值。默认情况下,当我们创建一个组合框时,我们只能从下拉菜单的选项中选择,尽管在可编辑组合框中,我们可以自己设置文本。为了使组合框可编辑,我们使用setEditable方法,为了检查组合框是否可编辑,我们使用isEditable。
语法: combo_box.isEditable()
参数: 它不需要参数
返回: 它返回bool
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)
# creating a editable combo box
self.combo_box.setEditable(True)
# checking if it is editable or not
check = self.combo_box.isEditable()
# creating label to show the status
label = QLabel("Editable ? : " + 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())
输出 :
