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。

In order to hide the combo box when item get selected we have to do the following –

1. Create a combo box
2. Add items to the combo box
3. Add action to the combo box
4. Inside the combo box hide the combo box with the help of hide method

编程需要懂一点英语

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())
