JFrame 16 Years Ago by orcboyx Hello all, Does anyone have a good tutorial that explains how JFrame works and how it can be implemented? Re: JFrame 16 Years Ago by Alex Edwards [url]http://java.sun.com/javase/6/docs/api/javax/swing/JFrame.html[/url] Re: JFrame? 13 Years Ago by stultuske JFrame has nothing to do with JOptionPane. a JFrame can be used to create your own user screens, so yes, also a 'dialogbox' with as many input fields you need, in the layout you want it to be shown in. [URL="http://docs.oracle.com/javase/tutorial/uiswing/"]This[/URL] would be a good place to start learning how to create such screens.
