arabic in combobox

Hi, I am using a combo box that is populated with arabic data, the problem I am facing is that the text in the combo box is being shown from left to right while arabic language is from right to left. I used TLF for text editor and it's working great, but I couldn't figure out how to use it with combo boxes, and also I couldn't find anything on the web regarding this issue.  Any suggestions on how I can solve this issue.  Thanks for your help, iNour
