Hello all,

I have a question.
GDI in windows is a device driver abstraction.
The client programmer does not know which device he is programming to.
It may be a display or a printer etc.
GDI hides all this,
and chooses the device driver currently installed on the machine.
The device driver written for windows has to conform to a particular interface. Hence GDI can work with any device.

Which design pattern is this?
Is it a factory?

Rgds,
Mandar
