Hi
I program for hobby and I'm just starting with Gforth. Forth is a different and interesting language!
Is there any implementation that offers a canvas for drawing at the style of the old DOS QBasic ?
I don't want to have to access the windows API and don't need to be able to add a GUI to my programs. I just need to open ane empty window and set the color of pixels on it.
Does it exist?
Kind regards
Antonio

widgets. I've not done anything serious with it yet, only played a little. But
it looked very promising to me.

That part can be done without the use of a windows API
Only when you would like to show the content of the window you need
to call some Windows API
But that part can be done by using one existing Forth definition.

I do'n't know about the QbAsic- method.

Here is the Forth way, which does EXACTLY what you asked.
Learn a few postscript words, write your commands to a .ps
file, and click on it with your mouse (outside Forth of course).
It will open in a new window with very high quality :-)
Or look up one of the bitmap binary formats (bmp, xbm, png, ...).
It's simpler because you don't need to learn postscript
(but it will look uglier).
I think Anton Ertl once showed the ps trick for the travelling
salesman problem (or something, maybe he'll tell you). Should
be on his Forth repository. This is even simpler because you
reuse existing code (oeps, burning oil, that hurt).

I'd be happy to give Gforth a try if it has some built in words for
this.
I realize this is all done with Windows calls and I did windows
programming many moons ago. But I haven't figured out the translation
between windows programming and doing it under Forth as yet.

Hi Rick,
I think I came across the same problem some time ago - how to emulate the old DOS text display ( even bytes data, odd bytes attribute ) under Windows.
Its a strange type of "progress" when what used to be trivial under DOS is now extremely difficult under Windows...
There is a similar problem with metadata in files : the Windows way is that Windows handles all metadata ( filename, data, read/write attributes etc... ), which effectively ties you in to Windows.
I have been trying to find an elegant way to save two byte streams (i.e. colour metadata) in a file. It appears to be a non-trivial problem.
Best regards,
Howerd

About the drawing canvas in Windows perhaps a simple C library as TinyPTC could be linked in some way.

Where's the docs for the GTK+ interface? I have the evaluation version installed, and I haven't seen any docs. Are the docs only available in the full version? If so fair enough. A cross-platform graphics oriented system that isn't Java is very attractive, to me at least. Nothing against Java in particular, it's just that it's rather on the bloated side.

Is your answer to mine about Tinyptc?
If yes tinyptc is just a wrapper to the windows GDI message loop. It was designed to ease the switch to Windows for graphical demo programmers used to DOS. Tinyptc has only three functions, open, close and doevents. If you want to draw to it you just set bits in a memory buffer.

The docs are in the source code! You could always build a DocGen
control file to produce a nice PDF manual. Or you could just
wait for us to do it.
