Hi experts, i am new to java and have looked at some of the tutorials at sun. However i don't seem to be able to get my head around the events in swing. I simply want to allow an input say in a TextField and save that to a variable. This i can do nomally in console with Scanner class. How does one go about it using swing. An example would be appreciated.

Thank you in anticipation

Craig.
