Window scroller

[yz]

What is the right way to make a window with a vertical scroller? To my pity, I have found only one dead link that relates to this question.

Place the pane you want to scroll inside a box.
Add a scroller to the box.
then use the scroller to adjust the x or y offset of the pane inside the box.
redisplay.

Ah, like in the cookbook recipe no. 36. Thank you.
But how can I specify sizes of the internal panel (panel with separate LAYOUT)?

[Graham]

Create a new layout for the box contents, and assign the layout to the pane of the box.

Create a new layout for the box contents, and assign the layout to the pane of the box.

It's understood, but how can I specify that new subpanel must be, let's say 300x300 to match sizes of box? Without it, the lesser panel opens a part of the box.

[Graham]

lo: layout [ size 300x300 .. ]

So simply? Thank you.
Rebol GUI really needs good documentation...
