Hope I can explain this clearly enough! :) Assume I want to create (say) a vector drawing program allowing the user to draw shapes on a drawing area that resides within a scrolled window. I understand the standard way of doing this (i.e. create a drawing area of an appropriate size, then insert it in to a scrolled window) but it strikes me that this is an inefficient way of doing things for a large drawing area, as the complete drawing area needs to be maintained in memory, even though only a small part of it is visible at any time. This seems to be the way that most programs of this sort work (for example - dia). Would it be better to create a small drawing area which is always the same size of the parent window, then attach scrollbars which (via callbacks) then *dynamically* draw the required part of the image on the drawing area... If so, are there any examples of this method, as I've not been able to find any.... -- David J.
