here is the documentation for the graph unit:
http://www.freepascal.org/docs-html/rtl/graph/index.html
a simple test program is attached
program graphex;
uses Graph;
var
i: LongInt;
gd,gm : integer;
begin
gd:=detect; { highest possible resolution }
gm:=0; { not needed, auto detection }
InitGraph(gd,gm,'');
if GraphResult<>grok then
halt; { whatever you need }
for i := 0 to 100 do
begin
SetColor(Random(GetMaxColor));
LineTo(Random(GetMaxX), Random(GetMaxY));
end;
CloseGraph; { restores the old graphics mode }
end.___

It is possible to create a sdlgraph just like there is already a ggigraph. But none of the core developpers has plans to create it. If someone creates a sdlgraph we'll happily include it Peter ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal]Graph unit <-> SDL ?
Hi, I notice the Graph unit (for TP7 compatibility) is implemented against svgalib. Does anyone know if it is possible to create a SDL surface instead and have Graph draw to that surface? thanks, -- Ryan Underwood, <[EMAIL PROTECTED]> ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Did you init the mouse driver before or after switching to graphics mode? I noticed that some mouse drivers deliver different resolution depending on the active screen mode at the moment of their initialization. hope this helps, Klaus ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Delorie (http://www.delorie.com) Since FPC is a 32 bit compiler, it relies on the services of such an extender.

The best way to go about this is not to use the graph unit. The graph unit is provided for TP compatibility, but modern-day GUI systems do not work with the same paradigm. I suggest you look into using GTK or so. It's relatively cross-platform as well, and is quite well supported by FPC.

Is it a processor? Or an OS? Or what? I am running entirely in graphics mode and am using the graph unit to accomplish this. I am creating state-of-the-art graphics that can be manipulated by the user via the mouse. I simply need to be able to read mouse events (and also to change the mouse cursor).
