Open Graphics on Windows

Hi There,

I am running Windows XP and I am trying to open a window with dimension 20 x
20. I have tried many approaches and all of them open a window but not with
the dimension specified. The command I am using to open this window is 

Graphics.open_graph ":0 10x10+50-0";;

Just as a way of illustrating the problem: I start OcamlWinPlus v1.9RC4 and
type:

#load "graphics.cma";;
Graphics.open_graph ":0 10x10+50-0";;

And the window opens but not a 20x20 window.

How should I proceed? 

Besides, I have CigWin installed. Is it really necessary to run OCAMl
Graphics?

Cheers,
Marcel

Hello Marcel,

maybe this is a typo in your post, or maybe not, but did you notice that in 
the code you provide you request a window of size 10x10 and not 20x20 ?

Also you don't tell us the kind of application you're working on, but you 
should know that the module Graphics is just for minimal purposes, for example 
for short example when you just need a quick/minimal plotting solution.

For more advanced usage you should use the SDL bindings:
http://ocamlsdl.sourceforge.net/

The format of this string is implementation defined.
On windows the following format is recognized - "%dx%d+%d+%d"
See otherlibs/win32graph/open.c
