Hey guys, right now I'm trying to setup my GUI so that I can search for an Employee (which when clicked, disables all of the Text Fields, but not the ID, so I can search for the ID. But right now I have no idea on how to do this, and I also would like some help with fixing the layout of my GUI. Right now it is 2 buttons per line, and then at the bottom it only has one, so I want the "Add To File" button to be full length (across the GUI), I have tried to this myself by creating a new GridLayout for it, but then it ruins the whole design of my GUI. If anyone can help me with either of my dilemass that would be greatly appreciated.
