Method and system for providing feedback information on a graphical user interface

摘要

Embodiments of the present invention provide a computer implemented method and apparatus for processing user defined input on a graphical user interface (GUI). Initially, a first user defined input value is received in a first graphical processing element. This first graphical processing element determines if the first user defined input value is a valid input value. Typically, this is done by comparing the first user defined input value with a set of valid input values. The first graphical processing element and said feedback message are embedded in a second graphical processing element. The second graphical processing element receives a feedback message from the first graphical processing element if the first graphical processing element determines that the first user defined input value is invalid. The second graphical processing element displays the feedback message and the first graphical processing element in a GUI when the first user defined input value is invalid. The second graphical processing element uses the first graphical processing element to receive and process a second user defined input value. <IMAGE>
