Error handling (try catch)

[qxoz]

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)
