PyQt5 QSpinBox - 关闭旋转框
在本文中,我们将看到如何关闭旋转框,同时制作 GUI(图形用户界面) 当小部件的使用完成时,需要从屏幕上删除小部件,可以通过隐藏它来完成,但最好这样做是通过关闭小部件。
为此,我们将使用close()
方法。
Syntax : spin_box.close()
Argument : It takes no argument
Return : It returns bool
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 spin box
self.spin = QSpinBox(self)
# setting geometry to spin box
self.spin.setGeometry(100, 100, 150, 40)
# creating a push button
button = QPushButton("Click", self)
# setting geometry to the button
button.setGeometry(200, 200, 100, 40)
# adding action ot the push button
button.pressed.connect(self.do_something)
# action called by the button
def do_something(self):
# closing the spin box
self.spin.close()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
