Error handling (try catch)



  • Hi everyone!
    Is there any way to catch or detect access violation error?
    construction like
    @
    QString *str;
    try{
    str.clear();
    }
    catch(...){
    ...
    }
    @
    should throw error, but it doesn't.



  • The access violation error isn't thrown (exceptions are thrown not errors) - it occurs when you access memory that you don't own.

    Anyway you can initialize your pointers with 0 (null pointer) and then first check for 0 and only then call a member-function (to be a little more safer you can assign 0 to the pointer after you delete it then you detect the attempt to call function after the pointer is deleted)
