textbox

First, check what''s available under "Options".

To implement your own handling of things, though: what you need to do is add a Command to your TextBox. Then set an object to be the CommandListener for the TextBox (if you''re subclassing TextBox for implementing other stuff, then setting it to "this" will work just fine). Make sure the listening object implements the CommandListener interface, which consists of this one method:

public void commandAction(Command, Displayable);

The parameters are provided because several Displayables may have the same object as a Command listener, and thus several Commands might also be received. (The Displayables in question can even share Command objects).

In your commandAction implementation, you want to detect the combination of Command and Displayable that you''re looking for (your new "okCommand" or whatever you call it, and your TextBox instance) and provide the appropriate code (i.e. targetVariable = myTextBox.getString() ; ).
