pyqt通过stylesheet设置button按钮为椭圆

命令如下：
border:2px groove gray;border-radius:10px;padding:2px 4px;
应该和CSS很像

测试代码，直接运行就可出效果：

from PyQt5.QtWidgets import (QApplication, QWidget, QPushButton, QHBoxLayout,
                                        QLineEdit)
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys 
import cv2
 
 
def clickHandle():
    ##main代表按钮的容器widget的对象
    button = main.sender()
    print(button.objectName())

class my_window(QWidget):
    def __init__(self):
        super(my_window, self).__init__()
        self.button = QPushButton('test', self)
        self.button.setStyleSheet('border:2px groove gray;border-radius:10px;padding:2px 4px;')
 
 
if __name__ == '__main__':  
    app = QApplication(sys.argv)
    win = my_window()
    win.show()
    sys.exit(app.exec_())

效果
