I have a calculator application in java swing, which is working properly with mouse click input. Now I want it to read input using keyboard button stroke. I had heard about the glass pane in java tutorial, but i need to know any other simple method to meet the requirement.
KeyPadPanel is an example that uses Action and Key Bindings for numeric entry.
