I want to set a background image for my JPannel which contains many JTextField and JButton (I used g.drawImage()), but the the components won't appear unless the mouse passes by. I can't make a JPanel for every component because I have too many of them.

Can anyone please help or point me into the right direction?

It sounds like either you've overridden paint or failed to call super.paintComponent when painting your image.

Make sure that:

  1. You override paintComponent of your JPanel
  2. You call super.paintComponent before you perform any custom painting

For example

Also take a look at Painting in AWT and Swing and Performing Custom Painting for more details about painting in Swing

    Then I "assume" that you're overriding `paint` of a `JFrame` or other top level container, which you shouldn't do. Consider providing a [runnable example](https://stackoverflow.com/help/mcve) which demonstrates your problem. This is not a code dump, but an example of what you are doing which highlights the problem you are having. This will result in less confusion and better responses – MadProgrammer May 12 '15 at 23:26
  • Oh, and where are you "writing" `super.paintComponent`? – MadProgrammer May 12 '15 at 23:27

    In the `override paintComponent` method. – Shane van Wyk May 13 '15 at 00:09
  • Plus one to @MadProgrammer for attempting to answer this, and you for answering a question that was asked, but voted to close for 'lack of a runnable example' .. – Andrew Thompson May 13 '15 at 00:32
  • Unless you can provide a runnable example which demonstrates your problem, I'm unsure how much more support I can provide, as it's all guess work based on assumptions – MadProgrammer May 13 '15 at 00:51
