c++ - 在 Linux 下使用 QSignalMapper 时出现“无此类信号错误”

Question

No such signal QSignalMapper::mappedString(QString)` is the exact error

我正在为 OpenRGB 开发效果引擎插件，但在 Linux 上遇到了一些问题

QCheckBox* SelectedBox = new QCheckBox();
QSignalMapper* DeviceSelectionMapper = new QSignalMapper(SelectedBox);
DeviceSelectionMapper->setMapping(SelectedBox, "DeviceName");

connect(SelectedBox,SIGNAL(clicked()),DeviceSelectionMapper,SLOT(map()));
connect(DeviceSelectionMapper,SIGNAL(mappedString(QString)),this,SLOT( DeviceSelectionChanged(QString)));

DeviceSelectionChanged 在private slots:

另外要明确的是，这在 Windows 下确实有效（顺便说一下，我正在尝试在 WSL 上执行此操作，）
