设置和访问标签的名称——PyQt5
在本文中,我们将了解如何设置和访问标签的描述。
标签是在表单上显示文本的图形控制元素。通常是静态控制;没有交互性。标签通常用于标识附近的文本框或其他小部件。标签的描述是标签的细节,设置描述有助于更好地理解细节以供后端使用。
设置描述 –
Syntax : label.setAccessibleDescription(details)
Argument : It takes string as argument.
Return : No return value.
要访问描述 -
Syntax : label.accessibleDescription()
Argument : It takes no argument.
Return : It returns string.
代码 :
# importing the required libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore
from PyQt5 import QtGui
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
# set the title
self.setWindowTitle("Description")
# setting the geometry of window
self.setGeometry(0, 0, 400, 300)
# creating a label widget
self.label_1 = QLabel("Label", self)
# moving position
self.label_1.move(100, 100)
# setting up border
self.label_1.setStyleSheet("border: 1px solid black;")
# setting up the description of label_1
self.label_1.setAccessibleDescription(
"This is description of label")
# getting description of label_1
info = self.label_1.accessibleDescription()
# new label to display info
self.label_2 = QLabel(info, self)
self.label_2.move(100, 130)
self.label_2.adjustSize()
# show all the widgets
self.show()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
