how to remove those compiler warnings

<< < (4/4)

oBFusCATed:
Please commit them as separate changes and, also please increase the SDK version number in cbplugin.h and remember to fix all plugins to use the new API.

ollydbg:
Done in rev 8048 and rev 8049. Thanks for all your guy's suggestions!!!

ollydbg:
There are still some warnings like:

    virtual void Update() { wxDialog::Update(); }

--- End code ---

Any ideas to handle this issue? Thanks.

jarod42:

--- Code: ---class DerivedClass : public BaseClass
{
using BaseClass::hiddenFunction;

// other stuff.
};
--- End code ---
should remove the warnings.

but as seeing the code,
--- Code: ---ProgressDialog::update
--- End code ---
may be removed.

Note also that
--- Code: ---ProgressDialog::operator =
--- End code ---
should be private without implementation (or with the 'delete' keyword with C++11).

MortenMacFly:
...be careful here, this is a script binding. Squirrel needs an equality operator exactly as it is setup. So this might look weird, but its a requirement. You better don't change it, but we should comment these workarounds in the code.
