Re: Layout Doesn't Work (was: jLabel setVisible(true) Doesn't Work)

Nice project thanks, but I have two questions:

(Q1) How can you either modify this code or create a different project to use controls that were dragged to the JFrame from the swing Palette. The code is not to create the buttons, JFrame, JPanel, or JLabel.

I.E.:In Design View suppose you have a JFrame, jPanel1, jButton1, jButton2, and jLabel1 already on the Frame. They were dragged to the form. Your current project did not create them. The buttons and label are in the jPanel. How would you make jLabel1 become invisible and invisible using two buttons.

(Q2) I noticed that int the below project the buttons move when one of the buttons is pressed. How can you stop that from happening.
