There are basically three ways to create ScrollViews in IB:

1) Dragging a ScrollView+Text from the fourth standard palette;
2) Dragging a CustomView from the third standard palette, and
   changing it into a ScrollView with the Attributes Inspector;
3) Selecting "Group in ScrollView" from the Layout menu.

The easiest way to do what you want is probably (1) and perform
replaceSelWithCell: on the ScrollView's docView at run time.

Try this:

Create a Window containing a ScrollView+Text.  Drag a Format>
to your main menu (maybe a Services> as well).  You want to have
fun with your text.  :-)

Create a Button containing the image you want displayed.  (If you
don't have one, just use something handy, like NXdefaulticon.
Remember to click Title under Icon Position to change it to
Icon.)  Turn off its Bordered attribute, and click Disabled.
Resize if necessary.  Click Layout>Send To Back.  Then set its
Transparent attribute.  Don't panic!

Create an outlet for the Button ("myButton")
Create an outlet for the ScrollView ("myScrollView")

Create an action, which you'll connect to from some sort of
trigger (such as another button or a menu item).  After you've
created a project and unparsed, add the code

[[myScrollView docView] replaceSelWithCell:
    [[[myButton cell] copy] setTransparent:NO]];

to that action.

Compile your test application, and play with it.

This will give you a feel for how embedded graphic objects behave.

N.B.: this isn't the "right" (or the best) way to do this sort of
thing; I've taken a rather expedient approach.  Read the
documentation for the Text object before doing this in production
code--I've left out a lot of subtle details.

Sure.  In the Attributes Inspector, make sure Monofont is NOT
checked.  This is a prerequisite for being able to embed
graphic objects.
