[SOLVED] Problem using QTextStream as local variable
-
Here is the code and problem I am experiencing in a method I have. Like any responsible programmer I want to make sure that I do not let a dangling pointer go undeleted...
@
public someFunction()
{
QByteArray* mResponse = new QByteArray();
QTextStream outds(mResponse, QIODevice::WriteOnly);// do something with stream/array
delete mResponse; // doesn't cause error directly BUT
} // error occurs here when leaving the method if I delete mResponse.
@Basically if I delete mResponse, the program crashes upon leaving the method giving an Access Violation. The only reason I can think of for this is that QTextStream attempts to delete the QByteArray as part of its destruction... a pointer that has already been deleted. Is this true?
-
No, QTextStream doesn't delete the QByteArray, but QTextStream::flush() will be called when destroys the QTextStream.

Hi,
To add to 1+1=2, you don't need to allocate mResponse on the heap
@
QByteArray mResponse;
QTextStream outds(&mResponse, QIODevice::WriteOnly);// do something with stream/array
@is the usual pattern in this case
