Description
Most properties can be evaluated by the debugger!

If however a property has an accessor method which is a const member function the debugger is unfortunately unable to locate the method and complains that it cannot find the method.

A similar issue occurs if the property is not referenced (hence accessor method not referenced) because the code is physically not present as it was discarded by smart linking.

However the debugger cannot find the accessor method in the case of a const member function because it simply doesn't look for it.

It would presumably be quite simple for the debugger to look for both const and non-const property accessor methods. This clearly would not be necessary for a mutator method as it is rather unlikely (& illogical) for such a method to be const.
Clearly a class with a const accessor method cannot be shared with Delphi code (& perhaps cannot be __published) but that's a completely separate issue.


Example
-----------

class Tfoo
{
public:

__property int Bar = {read=GetBar};

protected:

int GetBar() const;
};


In the example above GetBar() is a const member function and therefore Bar cannot be evaluated by the debugger.
Steps to Reproduce:
The steps are as described in the example!
This is a feature request not quite a problem report.

Sorry about the steps bit. QS went a bit mental when I pressed Ctrl-Tab!

Then edit the steps.

Cheers,
I hadn't noticed that it was possible to do this. I'm still getting used to using QS.
