Hi,
I've been trying to write my own classes which incorporate IDLitComponent and widget_propertysheet. This allows the user to tinker with object properties via a GUI,
I'm very confused by IDLitComponent::GetPropertyByIdentifier. The method allows you to do a "ClassName::GetProperty, Name=Value",
however "Name" is only known at runtime.
For example
obj -> GetPropertyByIdentifier("BoringProperty", empty_variable)
somehow triggers
obj -> GetProperty, BORINGPROPERTY=empty_variable
This is something that I would very much like to do with my own classes without having to inherit IDLitComponent.
To be more precise, does anyone know how IDLitComponent::GetPropertyByIdentifier tricks the arg_present()
function into thinking that a keyword needs to be set?
P.S. I'm assuming that my class doesn't necessarily implement the ALL keyword and also assuming that I don't use the EXECUTE function.
Cheers,
Robbie
