PyQt5 QSpinBox – 添加前缀
在本文中,我们将看到如何为旋转框添加前缀,前缀基本上是在旋转框值之前插入的文本,前缀对于旋转框的每个值保持不变,即不可编辑。
为了添加前缀,我们将使用spin_box.setPrifix
方法。
Syntax : spin_box.setPrifix(text)
Argument : It takes string as argument
Return : None
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)
# adding prefix in combo box
self.spin.setPrefix("Value of x : ")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
