PyQt5 – 如何在选择新项目时隐藏 ComboBox

在本文中,我们将了解如何在选择任何其他项目时隐藏它们的组合框。有时,当组合框的需求得到满足时,它应该被删除,但删除它不会让我们重用它,因此隐藏它是一个更好的选择。

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"]
  
        # making it editable
        self.combo_box.setEditable(True)
  
  
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # adding action to combo box
        self.combo_box.activated.connect(self.do_something)
  
    # method called by combo box
    def do_something(self):
  
        # hiding the combo box
        self.combo_box.hide()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
