in reply to Entry widget with explicit submit button

What GUI are you using? If it is Tk, read Validation in Tk::Entry.

    Yes, I am using TK. I read Validation in Entry, but that gives you option of "focus" on entry box and "key". But what I need is a separate button for a user to validate it.

    (For example, a user may play around with the text in Entry box, but he may not choose to conform to changes and might close the window. So, I want a submit button alongwith it. Only when it is pressed, I'll take the input.)
      Such a functionality does not exist. You have to create a normal Tk::Button and implement the logic yourself in its -command.

        okay, but I can't think of a logic because -textvariable of entry widget is changed on the go (as and when user types/changes something). So, how do I revert back to original data on a call from -command of button? (I guess that should have been my exact question, Sorry!)
