The MainPanel.java extends JPanel. The PageOne.java extends JFrame. The MainPanel.java is where all the actions and etc. are being set. The MainProgram.java calls the MainPanel.java to display what is in the MainPanel.java. All of these works good until I put the dispose(); method on one of the My main concern is to update or refresh the entire JFrame. JFrame consists a JPanel containing a total of 8 diff components.

Java jframe vs jpanel

If I want to develop a a desktop application either I have to use JWindow or JFrame. java. 0 JFrame is the window; it can have one or more JPanel instances inside it. JPanel is not the window. You need a Swing tutorial: http://docs.oracle. Here is a program that creates a JFrame , creates a JPanel , and adds the panel to the frame.

Perhaps that's where the confusion comes from. But JFrame doesn't have any special class for it's contentPane member.

Does JPanel provide a separate container from that of JFrame? Yes. Confining graphics to a separate graphics component simplifies things. You can draw graphics using a containers "paint" method but it is more complicated. The tutorial has an article (with links to others) that can help you get started: Lesson: Performing Custom Painting

2018-06-05 I would recommend: You're using a GridLayout(2, 3)-- good.; I'd make it actually a GridLayout(2, 0, GAP, GAP) where GAP is a constant that allows a gap between JLabels. The first and second parameters mean 2 rows with variable number of columns. Then if you set the background color of the JPanel to yellow, make the JLabels opaque and white, give the background JPanel an empty border of GAP Java JFrame BufferStrategy vs Canvas BufferStrategy As can be seen from the Canvas class and the JFrame class, the methods related to BufferStrategy (of the Canvas and of the JFrame) don't come from the same parent. The createBufferStrategy of JFrame for example, is inherited by Window, which is not a Game programming: JFrame, JPanel, paint method Assignment Name ( Completion-Based ): JavaAWT In this lesson, you will learn to start drawing objects in Java using the JFrame class in Java's Swing Library (which is their library of graphics related classes).

It is similar to the panel in Abstract Window Toolkit (AWT). JPanel does not contain border, title bar or menu bar.
