On the windows platform,when graphics resource has been allocated ,does that
mean
the graphics has existed in the memory?So when you ask it to be
shown,(shell.open()),the graphics in the memory is pushed on the screen?

Typically no. Typically a paint request is sent on the open to the
shell, and passed in on the paint request is a graphics context. This
context is directly attached to the screen buffer (through the OS in
some manner). Then during the paint request you draw in this context,
which then draws on the screen.
