按名称设置类成员值

Question

I've a class, derived of QObject and it has some members. I load a configuration file with param value syntax. Each param is a member of the class and I want to set it's value to value .

How is it possible, if it actually is? Thanks much!

PS I could have made an associative array but it's not the way I prefer.

Answer 1

You have two ways of doing this:

1. Declare your members as properties by using the Q_PROPERTY macro. Then you can set it by name using QObject::setProperty(..) .
2. Declare a setter method with the property name (plus a 'set' prepended for example) and the Q_INVOKABLE macro (or just make it a slot ), then use QMetaObject::invokeMethod(..) to call it by name.

Answer 2

It's not possible in c++. The only way is an associative array
