PyQt5 QSpinBox – 检查是否允许包装
在本文中,我们将了解如何检查旋转框中是否允许换行。 Wrapping 会使从最大值变化值逐步上升到最小值,类似循环一样从最小值变化值下降到最大值。我们可以在setWrapping
方法的帮助下使旋转框中的包装允许。
注意:仅当您设置了最小值和最大值时,包装才有意义。
为了做到这一点,我们使用带有旋转框对象的wrapping
方法。
Syntax : spin_box.wrapping()
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, 250, 40)
# setting range to the spin box
self.spin.setRange(0, 9)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# making spin box wrapping the value
self.spin.setWrapping(True)
# setting status tip to the spin box
self.spin.setStatusTip("Small Value")
# creating a label
self.label = QLabel(self)
# making label multi line
self.label.setWordWrap(True)
# setting label geometry
self.label.setGeometry(100, 200, 250, 60)
# checking the wrapping is allowed
value = self.spin.wrapping()
# setting text to the label
self.label.setText("Wrapping Allowed ? : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
