hi,
the way i have solved this is problem is to set up a graphing coordinate
system between the user coordinates (from the CAD file) and the window
coordinates: this amounts to setting up a structure containing the min and
max of the user coordinates and the window coordinates (and probably more)
to be used to translate between the two.
then write the functions user_to_pix_x(), user_to_pix_y(), pix_to_user_x()
and pix_to_user_y() for the coordinate system and you can get to there
from here with ease, always right vs. the size of the window.
i can provide code if you like.
cheers,
richard

hi,
please help me i have a logic problem. i write a application
that draws CADpoints from a Cadfile (x,y coord.) on a
drawingarea. so far so good. now i wanna align this points to the
windowsize. my idea was, add the windows x-y coord. to the pointcoord.
but this is not very suggestive. i know this is not a real gtk thing but
i thought some of you are really c++ cracks and could bring me on the
right way. thanks!
