Re: [Development] std::optional for Q_PROPERTY

Hi, > That would mostly work, unless you want > a RESETable property, where RESET shouldn't lead to a nullopt value. It’s perfectly valid to have RESET set the value to whatever it thinks is correct, isn’t it? All it means is I can assign `undefined` from QML and have _something_ come out of i

Re: [Development] std::optional for Q_PROPERTY

Hi, as far as QMetaType is concerned: We need a way to have some introspection on the "contained" type. That can't really be shoehorned into the current QMetaTypeInterface, because that one has neither enough space, nor a useable function pointer that could be hijacked. However, incrementing the Q

Hi, I would like to voice my support for this and even extend the idea: * std::expected would also be nice here, because it can tell you /what/ went wrong. Yes, I know it is C++23... * Support for smart pointers, see QTBUG-60136 . It is alread

[Development] std::optional for Q_PROPERTY

Hi everyone, something that came up during this year’s KDE Akademy was that we believe Q_PROPERTY should be able to handle std::optional, such that you get a null QVariant out of it if it has no value. The main use case being interfacing “more modern C++” with QML in a type-safe way, rather t
