我正在创建一个应用程序,在该应用程序中,我需要做一个清单,并列出另一个班级给我的清单。用户将选中所需项目旁边的复选框,然后单击一个按钮。对于已检查的那些行,我要打印“您检查的号码___”。在相邻的QBoxGroup的QLabel中。
((在我的实际应用程序中,我正在遍历类,在类中将在其中调用函数)。我很难遍历列表,因为我必须检查是否选中了该框,并且该名称是否是我要打印的名称(打印的语句与实际名称不同,因为在我的应用程序中我将在我所在的类的类中调用一个函数。
我也不确定如何处理该问题,如果用户使用QLabel选中了多个框,我可以打印多个语句。我可能必须将其设置为用户一次只能选择一行的地方,但这是一个比上面的问题小的问题。

现在,statsButtonClicked()函数返回TypeError: 'QStandardItemModel' object is not callable
我已经尝试了这些StackOverflow页面上的信息,但似乎无法弄清楚如何查看该行的名称以及是否选中该行:
row
,另一方面,假设该错误不存在,并且已使用逻辑检查了2个选项,则您正在编写“数字X”,然后将其替换为“您检查的数字Y”。逻辑是将已检查项目的文本保存在列表中,如果该列表不为空,则串联信息,否则指示未检查任何项目。
def statsButtonClicked(self):
checked_options = []
for index in range(self.model.rowCount()):
item = self.model.item(index)
if item is not None and item.checkState() == Qt.Checked:
checked_options.append(item.text())
if checked_options:
self.analysis.setText(
"\n".join(["You checked number {}".format(option) for option in checked_options])
)
else:
self.analysis.setText("You didn't check anything")
