[Zope] how to tell if displayed in a frame

[Jim Washington]

It can be done in server-side code, if you know when you put the
document in a frame or not.
Something like the following might help:

In the document in question, do some code like:

<dtml-if in_frame>
...display definitely in frame
<dtml-elif not_in_frame>
...display definitely not in frame
<dtml-else>
...default display, which may be the same as one of the above
</dtml-if>
You will probably want to factor out the duplicated content into
subsidiary methods.

Now, if you want the default view, call it as <dtml-var mydoc>

If you want it in its frame view, call it as <dtml-var "mydoc(_.None, _,
in_frame=1)">
You might want to make a dtml method called e.g. myframedoc with the
above code so you can call it as a url.
<frame src="myframedoc" title="blah">

Another way is to call the document in HTTP:get format in the frameset.  
like: <frame src="mydoc?in_frame=1">
