I'm interested in Klayout's basic design of layout drawing on Qt. The reason of my interest is..
I have several software development experience in GDS processing but these are just data and no drawing so I don't have no experience/idea of drawing layout except small and flat layout using simple QPainter widget.
I have a dream of developing LAYOUT VIEWER BY MYSELF so I seek enlightenment on large layout drawing and data treatment.
It is sure that watching the code is better than hear. However I'm beginner of Qt programming 3 month long and does not catch up large data drawing technique.
Again please tell me about basic design of layout drawing and
data storage on Qt.
