Interesting NetBeans GUI Builder Behavior
By Geertjan-Oracle on Feb 24, 2012
I changed the JPanel from yesterday's blog entry to a JTextField, added it to the Palette, dragged it into a JFrame and then discovered that even in design mode the vertical line moves left and right... which is cool but weird!
Above (top left black background) you see a deployed JFrame where the vertical line moves left and right in the JTextField, as expected, based on the code shown yesterday. But even in design mode in the IDE (right part of the screenshot above), the vertical line is ALSO moving left and right, while I'm designing the JFrame. Does that mean that the JFrame is somehow deployed even while I'm designing it?
