Open a File on a window and provide Search, Edit, Save, Font +/- functions in ExtJS4

Hi All,



I'm looking for a Text editor kind of functionality on a window in ExtJS4. Basically I would like to open a file on a window, provide find text/Search text, Edit, Save data onto same file and increase and decrease the font size in the same window.



Can someone please suggest how can I achieve this?



Thanks & Regards
