PyQt5 – 检查单选按钮的布局方向是否从右到左
在这篇文章中,我们将看到如何检查单选按钮的布局方向是否是从右到左。默认情况下,单选按钮的对齐方式是从左到右,但在setLayoutDirection的帮助下,我们可以改变其对齐方式。从右到左的方向基本上告诉我们,指示器在右边,文本部分在左边。
实现概述。
1.创建一个单选按钮
2.为单选按钮设置方向(可选)
3.创建一个标签,显示是否从右到左对齐
4.在isRightToLeft的帮助下检查对齐方式并将其保存在变量中
5.在setText方法的帮助下,将答案设置到标签上。
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 a radio button
radio_button = QRadioButton(self)
# setting geometry of radio button
radio_button.setGeometry(200, 150, 120, 40)
# setting text to radio button
radio_button.setText("Radio Button")
# setting direction
radio_button.setLayoutDirection(Qt.RightToLeft)
# creating label to show output
label = QLabel(self)
# changing position of label
label.move(200, 200)
# check if direction is right to left
check = radio_button.isRightToLeft()
# setting output text to label
label.setText(" Is direction is right to left :" + str(check))
# adjusting the size of label
label.adjustSize()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
