Problem subclassing QIODevice

[ocgltd]

I want to subclass QIODevice, so that I can implement a class which operates in Sequential mode (not random access).

However, it appears that the Sequential property offers a getter (isSequential) but no setter. How can my subclass set Sequential mode?

Hi,

isSequential is virtual. You overload that method.

There's no reason for a setter as devices usually can't change their type like that on the fly.

@SGaist I saw some (old) source from IODevice.cpp that showed isSequential checking bits/flags of mode. But another source showing it just returning false.

So if I simply override the function to return true, there is nothing further I need to do/set?

You need to implement it to work sequentially and that should be it.
