PyQt5 QSpinBox – 访问标题
在这篇文章中,我们将看到如何访问旋转框的标题,标题基本上是旋转框的标题,但它是不可见的,标题仅用于后端用途。自旋盒的标题与主窗口的标题相似。
为了做到这一点,我们使用windowTitle方法。
语法: spin_box.windowTitle()
参数: 它不需要参数
返回: 它返回字符串
以下是实现方法
# 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, 250, 40)
# setting prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# caption
caption = "Spin Box 01"
# setting caption
self.spin.setWindowTitle(caption)
# creating label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 200, 30)
# getting caption
get_caption = self.spin.windowTitle()
# setting text to the label
label.setText("Caption : " + get_caption)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
