Is it Possible to show a previously hidden JFrame using a keylistener
- by JIM
here is my code, i basically just did a tester for the most common listeners, which i might later use in future projects, the main problem is in the keylistener at the bottom, i am trying to re-show the frame but i think it just cant be done that way, please help
ps: no idea why the imports dont show up right.
