Hi,
The action is defined as follows:
|
Quellcode
|
1
|
<action name="popup" scope="private:POPUP" args="type, content, width, height, scrollbars, onclose_callback"><![CDATA[
|
Later, it copies that value of "scrollbars" to the .htmlscrollbars property of the plugin.
The plugin itself is encrypted and source code is not available.
But as for your question: yes, it enables/disables the scrollbars of the popup.
gr,
K.
