PyQt5 QDial – 获取方向属性
在本文中,我们将了解如何获取 QDial 的方向属性。该属性保存滑块的方向,方向必须是垂直(默认)或水平。垂直方向关联值为 2,水平方向关联值为 1,可以借助setOrientation
方法将其设置为 QDial。
为了做到这一点,我们使用带有 QDial 对象的orientation
方法
Syntax : dial.orientation()
Argument : It takes no argument
Return : It returns Orientation object but when printed it shows the associated value of orientation
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, 500, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating QDial object
dial = QDial(self)
# setting geometry to the dial
dial.setGeometry(100, 100, 100, 100)
# making notch visible
dial.setNotchesVisible(True)
# setting orientation to it
dial.setOrientation(Qt.Horizontal)
# creating a label
label = QLabel("GeeksforGeeks", self)
# setting geometry to the label
label.setGeometry(220, 125, 200, 60)
# making label multiline
label.setWordWrap(True)
# getting orientation
value = dial.orientation()
# setting text to the label
label.setText("Orientation : " + 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 :
