Hi
I'm trying to draw something like a crossword on a widget, and to that
end, I'm using wxDC.DrawRectangle.
Suppose I want to draw 2 squares, side by side and such that they
overlap over a common edge. I would do something like this:
...
dc = wxPaintDC(self)
...
dc.DrawRectangle(0, 0,10,10)
dc.DrawRectangle(10,0,10,10)
...
i.e., draw 2 squares 10 pixels wide.
Now, If I print the drawing, the two squares are perfectly aligned; but
on screen it looks like the common edge is wider than the other edges.
On the other hand, if I do:
...
dc.DrawRectangle(0, 0,10,10)
dc.DrawRectangle(11,0,10,10)
...
then the squares looks ok on screen but not in paper 
In "Print Preview" mode, both methods looks ok on certain magnifications
and bad on others.
Perhaps I don't understand the meaning of DrawRectangle parameters;
let's see:
The statment DrawRectangle(100,100,10,10) should draw a rectangle
starting at pixels (100,100) and ending in (110,110), right?
Thus, If the pen is 1 pixel width and I draw another rectangle with
DrawRectangle(110,100, 10,10), then it should be a line 1 pixel wide
from (110,100) to (110,110), isn't it?
What should I do?
Thanks in advance.
