Customize the Link Dialog in dojo editor

Release: Dojo 1.6.1

I am working on the dojo editor. The dojo editor has the Link dialog in which the target url can open in 4 ways - Current Window, New Window, Topmost Window, Parent Window. Is there any way I can disable the options开发者_如何学编程 I dont need? I tried removing the 3 by modifying the LinkDialog.js. It removed the ones I didnt need but still retained the space for them.

Answering my own question: Modified the LinkDialog.js to add disabled param in template
