PyQt5 QSpinBox – 访问状态提示
在本文中,我们将了解如何获取旋转框的状态提示。状态提示基本上是开发人员设置的文本,用于向其他开发人员提供有关旋转框状态的提示(信息)。例如我们可以在它的值大于 90 时将状态提示设置为“高值”。我们可以借助setStatusTip
方法将状态提示添加到旋转框。
为了做到这一点,我们使用带有旋转框对象的statusTip
方法。
Syntax : spin_box.statusTip()
Argument : It takes no argument
Return : It returns string
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(1, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# 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)
# getting status tip
value = self.spin.statusTip()
# setting text to the label
self.label.setText("Status Tip : " + 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 :
