Is it possible to create transparent faces? A face over a face.. 
So not an image!

Yes, set the color of the face to NONE

thats very transparent ;-)

If SAVED-AREA is true then it won't recalculate the transparency 
on redraw...

I just need a little color in it but the backface needs to be visual 
through the front face...

I thought saved-area was for images only ?

Color: none effect: [colorize what-ever-color]

Saved-Area is for saving the transparent area of a face...

Thanks Ammon !!

If you set it to true then it gets replaced (changed from a Logic! 
value to an Image! value) with the background or transparent area 
of the face so that the background doesn't recalculate itself...

You're welcome!

On all things View, the best reference that I have seen yet is http://www.dobeash.com/it/rebgui/

The information I just gave is available there...

heee i dont know that url ;-) Thanks again!

NP

HA !

There it is !! the FormDesigner ...

is was searching for that one for a long time...

Wasnt there an GUI builder too ?

Uhm...  There have been a number of them built but none of them have 
passed Alpha stage if they ever actually hit what could be called 
Alpha...

Yes i think that was 3 years ago...

never heard anything from it again

http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=layout-1.8.r

I played a little with a script that Carl wrote to demonstrate how 
to build a GUI builder but ultimately decided to rebuild my own.

I had Bo build me an engine for creating faces for the IDE I'm writing 
but have since decided to use GLayout as my GUI engine which makes 
the engine Bo wrote obsolete.

Glayout ??

Mmmm

http://www.rebol.it/~steel/is the homepage for GLayout...

aaa Right... yes i know that, but i actualy never used it...

It is getting better and better as we improve it for use in Anvil...

lets have a look again then ;-)

Scrollpanes are in the middle of getting a revamp which will include 
an enhancement or two to the layout engine itself but the revamp 
isn't available yet...

the complete website has a new layout too ;-)

ill have a closer look

Mmm still no luck on making 1 face transparent when it moves over 
another face..

I tried different thinks but no result on transparentcy with color.. 
Or its 100% transparent or not ;-)

Anyone any hint ?

The idea is to have 1 face to be transparent in its own color so 
the face below it get visable..

you need MERGE in the effects block

older versions (i.e. 1.2.1) didn't need it

merge ? Mmmmm lets investigate that ;-)

Well im not quiet sure what you mean Gabriele..

Its not as simple as it seems after all..

it must be possible to have 1 face turn into transparentcy when it 
moves over the other face. Not 100% transparent but lets say 60%...

odd ;-)

Playing with alpha channels requires some skill and experience. ;~>

Can you give us a quick snippet that demonstrates how you attempting 
to create the transparency and how the faces are being moved over 
each other?

What Gabriele mean :
