World: r3wp

Yes, it is ok on the example codes. On this one, only the first widget 
is displayed
gtk-begin
gtk-view window [
	"Hello World"
	label "Hello, Red/System GTK+ world!"
	button "ok"
]

Right, there are bugs in detecting object/struct/widget types

It prints warnings when you start from a command prompt

ok, I see

The GUI constructors are written to be flexible, so rather than crash, 
they work as best as they can while issuing warnings when they encounter 
errors

good strategy

Thanks. It makes them backward and forward compatible to some extent

Bug should now be fixed.

Not for me

I have tested with your code example and GTK debug version. I'm getting:

type: 1005
value: 0
Window: skipping missing widget.

I'm still getting 1000

I do a quick test on Linux, just in case...

missing widget

 in itself is already a bug. If it would recognise it as system/alias/gdk-image! 
 it would say "missing icon"

Ok, looking on that.

In my test program, gdk-image! is alias 1018, so 1005 seems way off

Yes, I have located the issue in compiler code, I am now looking 
for a durable fix.

Pushed a temporary new fix for #172, let me know if it works for 
you now.

Yes, thanks!

I've moved the GTK library initialisation into the binding, so that 
the explicit gtk-begin isn't necessary anymore; but it prevents using 
the workaround still needed for #129

I suppose local variables are not initialised?

Implemented attaching an object to a (button) action

Here's an example that gets input from a line entry field:

Red/System [ ]

#include %GTK.reds

button-pushed: function [
	[callback]
	widget				[gtk-widget!]
	data				[handle!]
][

 print ["Input: "  gtk-get-entry-text  as gtk-entry! data  newline]
]

input: field "Here"

gtk-view window [
	170 90  gtk-position-center
	"Red GTK+ Input Field"
	fixed [
		70 10  label "Input:"
		 5 30  input
		60 60  button [50 25  "OK"  :button-pushed input]
	]
]

Added a few more examples

Doc, the examples are now suitable for demonstrations, such as coming 
week

Nice!

adding some actions could be attractive for a demo

Sure, if you can double my hours in a day

Doc, the 0MQ binding still works, so you can use the request/reply 
example, on Linux or Windows

A fairly impressive demo is to start the client before the server

As soon as http://www.raspberrypi.org/will be available, the ARM 
emitter would be strongly necessary, Interresting toy for less than 
expected (if they keep promises)

unfortunatelly raspberrypi website is a mess

Yep, we're living in interesting times

The cURL binding still works, but I don't have a nice example for 
it yet

I've cleaned up my SDL binding; although sound still doesn't work. 
It's now here:

http://red.esperconsultancy.nl/Red-SDL

I've added the PeterPaint example, with some more comments

It demoes mouse events, drawing, program arguments and loading a 
bitmap file

I've added a sample.bmp file from SDL for easy access

SDL can be demoed on Linux. I haven't tested on Windows yet, although 
it should at least almost work

Great, thanks!

You can put GTK and SDL on the website now, if you want

Sure, I will.

Is there an idiots guide for new users and developers?

Have you looked at the webiste - http://www.red-lang.org/- ?

I don't think there's a quide guide on getting started for people 
new to red and/or rebol ...

guide2 = quick guide

Red-SDL , and the PeterPaint example works under Windows XP apart 
from the name of the dll which is SDL.dll instead of libSDL-1.2.dll

Ah, that's a weird transformation. I'll add it. Thanks for testing!

Where did you get the Windows SDL binaries?
