Do you know how to disable RTTI?

yes

darn can't leave it at a yes, why do you want to disable it? And I assume its essential for Qt's internal classes and methods in the first case.

Hi and welcome to devnet,

Do you mean add "-fno-rtti" to the compiler flags ?

I am using MSVC and i want to disable it to remove my classes name in compile time. I am happy that there is so many helpful members here

Are you using Qt Creator or Visual Studio directly ?

@SGaist I am using qt creator sir and i am developing qml quick application. is there any problem if i do that?

That depends on how you want to use these classes. Out of curiosity. Why do you want to disable RTTI for that application ?

Just for educational purpose. I just want to remove my classes name

Based on this page of the VS documentation, you would need to add "/GR-" to the compiler flags. But its goal is not to hide anything. It just does not generate some additional information.

You are removing the negation of the option.

ChrisPanda · 14 Sept 2020, 10:12

Sorry sir but i dont understand, can you please explain it sir?

@ChrisPanda
You have added

QMAKE_CXXFLAGS -= /GR-

Note that you have used -=. That removes the option. But @SGaist wants you to add that option:

QMAKE_CXXFLAGS += /GR-

Note the +=!
