[Typo3-dev] Prevent displaying of content in plugin

[René Ott]

Hello,

inside a plugin I have a popup window that links back to the plugin itself.
The problem is that inside the popup window still the whole page around 
appears. So the content of the popup is not just the content that comes 
from my plugin but the rest too.

What I would like to do is to prevent the all the stuff around from 
being displayed.

Some investigation showed that the function

isOutputting( )

in class.tslib_fe.php controls if the content gets displayed or not. But 
this returns only false if a jumpurl is not set. I cannot set a dummy 
one because of the headers that get sent. With one or two lines that 
would be easily changed but I want to keep the core untouched.

Exists a different solution for this problem (maybe through modification 
of cObj) ???

greetings,
René Ott
