PyQt5 – 当新项目被选中时如何隐藏组合框
在这篇文章中,我们将看到如何在任何其他项目被选中时隐藏组合框。有时,当组合框的需求被满足时,它应该被删除,但删除它将不允许我们重新使用它,因此隐藏它是一个更好的选择。
为了 在项目被选中时隐藏组合框,我们必须做以下工作 –
- 创建一个组合框
-
在组合框中添加项目
-
为组合框添加动作
- 在组合框内用hide方法隐藏组合框。
下面是实现方法
# 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, 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())
