print(eachObject["name"] + " : " + eachObject["percentage_probability"] ) 然后,双击FirstDetection.py运行代码,并稍等片刻,识别结果就会在控制台打印出来。一旦结果在控制台输出,在包含FirstDetection.py的文件夹里,你会发现一张新保存的图片,文件名为“imagenew.jpg”。

在这个例子中,我们定义了一个槽函数onButtonClicked(),用于显示一个消息框。然后,我们使用QObject::connect()函数将QPushButton的clicked()信号与槽函数连接起来。当按钮被点击时,槽函数将被自动调用,从而弹出消息框。 总之,Qt提供了一套丰富的功能和工具,使得开发跨平台GUI应用程序变得更加容易。通过使用Qt Designer...
