After a long break, I have started banging my head against the wall trying
to do this.  At least this time I think I am making progress.  I can at
least compile now without errors and only a hundred or so warnings.  I have
been taking notes as I have been going along and I am posting them to here
as I go:

      http://www.imp.org/visitors/guiext/cookbook.asp

Any comments, tips, or hints will be much appreciated.

Thanks

When I get some time in the next couple of days, I'll try to follow your
cookbook and see how far I get.  I'm wanting to write a GUIEXT Java API, but
hadn't had the time to even research where to begin.  It may be a week or
two before I get to it, but I'll let you know how far I get following you.

Some tips for compiling POV-Ray (or more correctly, MegaPov) with 
Borland's compiler could be found in thread 'free borland' in this very 
same newsgroup, dated 2001-04-17. Perhaps it will help, although it's 
not related to GUI Extensions.

Ok, I'm following your cookbook, and so far so good.  I haven't tried a
compile yet, but I got the Borland compiler, and the POV 3.5 source.

There's a type under "Installing POV Source" item number 5.  It says:
    Copy the file FRAME.H from C:\POVSRC to C:\MYGUIEXT
I think it should read.
    Copy the file FRAME.H from C:\POVSRC\SOURCE to C:\MYGUIEXT

At least that's what it is for the 3.5 source.

Ok, I got the guidemo.c compiled and installed into POV-Ray, pretty cool.

I used the following compile arguments with bcc32.exe

bcc32 -WD -O2 -Vx -Ve -X- -a8 -b- -k- -vi -tWD -tWM- -q -lD"" -laa -lTpd -lx
 -lGn -lGi -eguiext.pge *.c

Which I got from this web page:
     http://www.textpad.com/support/tips/borlandtip.html#dll

Then I modified the PVENGINE.INI file and added followling line.  The
guiext.pge is just the temporary name I working under, I'll change it as per
the license agreement when I get to a release point.

ExtDll16=u:\source\com\unpuzzled\d3\guiext\guiext.pge

under the [GUIExtensions] header...

So the file ended up looking like this.

[GUIExtensions]
UseExtensions=1
ExtDll15=D:\Program Files\Moray For Windows\MorayCtrl.DLL
ExtDll16=u:\source\com\unpuzzled\d3\guiext\guiext.pge

Started up POV and to my amazement there it was...

Now I just have to figure out how to implement what I really want it to
do...

Wow! Thanks. I just started down playing with the compiler/linker switches
last night at
the airport.  Lot's of activity, but little progress.  I will update the the
instructions on the
web page this weekend with your findings.

I know!  That problably will make the initial compile look like a walk in
the park.

Thanks

I cannot do an (*Instance->Request)(RequestGetVars, &ExternalVars) ; in the
following method. I assume its because POV hasn't fully initialized Instance
yet. I need to know the Instance.HomePath so that I can read my .ini file
and initialize Instance.Enabled correctly.

What do I do?

Is there some place else I can set Enabled after POV has initialized the
DLL?  Or do I just have to know the directory where POV is installed,
without being able to ask POV itself?

Thanks in advance,

Andrew Wilcox

You could ask windows for the path to your DLL. Or you could store the state in
the registry instead of an INI file (IMO this is the best choice, POV uses an
INI file because it predates Windows 9x ; you don't have to follow our example).

Alternatively you can look at HKCU\Software\POV-Ray\CurrentVersion\Windows\Home.
Note that v3.1 of POVWIN uses HKLM for this key. If both version are installed,
the HKLM one will point at v3.1, and the HKCU will point at v3.5. But there will
also be an entry in HKLM\Software\POV-Ray\v3.5\Windows\Home pointing at the v3.5
install (provided that the person who installed it had admin rights).

Could I put in an HKCU\Software\POV-Ray\GUIEXT\<myguiext> key?  Or should I
use a completely different path all together?

The registry would be easier to access anyway, than a file.
