To share, this is a post i found about it (by cphillips)

Additionnal stuff:
http://www.suwiki.org/suwiki/index.php?title=Ruby_Tutorial_-Dialog_Boxes_and_WIN32API%28Advanced%29

the Win32API.so link below wont work
you can get Win32API.so from there
After you install ruby into a folder, say c:\RUBY, then Win32Api.so will be in
c:\RUBY\lib\ruby\1.8\i386-mswin32

the original post:

-The function is called "cleanSlate()".
-It will remove all the menus and the window boarder.
-You need to manually disable any toolbars you dont want.
-Requires win32API.so lib(attached).

NOTES:
-It works by looking for a window named "Sketchup - Untitled".
Therefore it will only work when no model is loaded. You could change
this by editing the ruby.
-It wont fully work at startup because the "Plugins" menu gets created
after the cleanSlate() function is run.

mmm, legal, it's not.
but im tricky for school.

... possible to fit the "drawing zone" into a webdialog ?
... is there any "transparency" property for a webdialog?

i suppose the best way ("or the easy way") is a floating webdialog as a control bar
over a naked sketchup original window.

control bar connected to Ruby functions.

my question:

Is it possible to extract the "drawing zone" from sketchup and then, use it somewhere else using Ruby and Sketchup's API?

Id like to insert the drawing zone in a selfmade form....... and use it code behind with Ruby. Or, remove all from the original sketchup's main screen.....menus, toolbars and the rest.

first: is it possible ?
if yes, how can i do ?

thanks
