我的程序不会添加或减去Qline编辑的输入 它打印输入彼此相邻! 尝试了一切并搜索了互联网。
出来是1111,应该是22。
提前谢谢。import sys

self.sellamountsetting.resize(70, 20)
self.sellamountsetting.setText('11')
print(self.buyamountsetting.text())
test = self.buyamountsetting.text() + self.sellamountsetting.text()
print(test)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)

mainWin.show()
sys.exit(app.exec_())
答案 0 :(得分:1)
调用QLineEdit.text()
会将QLineEdit中的文本作为字符串返回。您必须将其转换为int才能将它们添加到一起。
尝试:
test = int(self.buyamountsetting.text()) + int(self.sellamountsetting.text())
