Using a string for QPanel Template

Hi I was wondering if there is a simple way to use a string as the template of a QPanel instead of specifying a file.  I have a QPanel that needs to render several different possible templates, these are somewhat dynamic and change based on the user logged in etc.

I suggest doing a lot. Tpl.php for each case

example

if (x)
$ this-> pnl-> Template = “another1.tpl.php”;
else if (y)
$ this-> pnl-> Template = “another2.tpl.php”;
else
$ this-> pnl-> Template = “another3.tpl.php”;
