PyQt5 QSpinBox – 隐藏旋转盒
在这篇文章中,我们将看到如何隐藏旋转盒,当制作GUI(图形用户界面)时,当使用完widget后,需要将widget从屏幕上移除,为了做到这一点,我们可以隐藏旋转盒。
为了做到这一点,我们将使用hide()方法。
语法: spin_box.hide()
参数: 它不需要参数
返回: 它返回无。
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 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):
# hiding the spin box
self.spin.hide()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
