As to my experience in my Java Swing programming, I have only used absolute layout, in which I can position objects anywhere in frame using a Window Builder plugin for Eclipse. But the problem with that is, it's hard to maintain, and when the frame is re-sized the objects remain in their positions which is a not good.
Is there a layout manager in Swing that uses absolute positioning (I'm using Window Builder) but when the frame is resized, the objects inside the frame go with the flow?
you can try this site, I have been using it for some time and I am very please,

I can't scale and move components in IntelliJ with its GridLayout. The problem is when I move/scale components they don't move to the exact place.

You should learn how Java Swing Layouts work. Most layout managers do not allow you to place the components where you want (there is so called Null-layout, but it's not supported by IntelliJ IDEA).
You normally use splits, spacers and constraints to define where the components will appear and how they will resize when the form is resized.
I'm having the problem that I don't like the way all layout managers position elements for the whole window.
I'm using the WindowBuilder Pro plugin for Eclipse to design the gui.
Either I support resizing of the window and use a layout manager (crappy positioning) or I choose the absolute one which allows me to place everything wherever I want but it's non-resizable and hard to maintain.
What's the trick in getting what you want using layout managers? How can I keep more control of the placements? Using panels and nested layout managers?
My friend and I are working together to write a Java program, and I am taking on the task of designing the GUI. Our GUI requires a background image for the JFrame, and the image needs to be able to change based on the user's actions. I have placed the images that I want to use as the background in the project as a resource, and I would like to ask for help finding the resource path, and setting the resource path as the background image in the JFrame.
I am using the Swing GUI Builder for NetBeans to design the GUI. Can someone please offer me some help? I have no experience with GUIs, and my friend has little experience with basic Java coding, so we are assigning parts based on our knowledge.
If you don't want to resize the images (as the frame changes), you could simply set the frames layout to BorderLayout and use a JLabel to display the images. Otherwise you will need to construct a custom component (using something like JPanel) and render the image yourself
Looking up embedded resources is a simple process of using something like getClass().getResource(...), where the parameter is the path to the resource, where the root is the top level source folder in your project.

I have a swing gui which has proper JPanel and JDialog size on windows platform with screen size from 13inch to 15inch. What I refer as proper size is that all the components in JPanel and messages at JDialog are properly shown.
However, when running under Ubuntu linux with Genome/Kde desktop, I find the not all components or messages are fully shown and it appears that either width or height is not enough and the GUI interface is cropped
Anybody has ideas of how to fix it?
To have consistent UIs in multiple platforms you have to use LayoutManagers.
http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html
There are several graphical editors that support creating swing user interfaces using LayoutMaganers. One example is WindowBuilder for Eclipse: http://www.eclipse.org/windowbuilder/
Call Window.pack() for your JDialog before showing it to make the window just big enough to fit all the components in it. This requires that you are using layout managers.
how can I make a gui interface with everything in order I know the borderlayout, flowlayout and gridlayout but what is panel? im so confused please help in visual basic I just dragged and dropped. im using netbeans 7.1, I can do layouts and stuff the problem is its so confusing to make all these panels and stuff and (x, y) axis where to place them I want the gui nice and neat
how can I make a gui interface with everything in order
For a single column or row, see GridLayout1 & BoxLayout2, as well as JToolBar3 & JList4.
See 'How To Use':
GridLayout
BoxLayout
JToolBar
JList
Have you seen these examples http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html ?
I was used to creating java GUI with manual coding, I mean not the drag and dropped that auto-generates the codes, so it was a lot easier for me to switch with GUI designer such as Window Builder plugin for Eclipse or the built-in swing designer of NetBeans.
I suggest you to start with the basic of Layout Managers with manual coding. Here's a good link... http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html
Start with the easiest: FlowLayout, GridLayout, and BorderLayout. These layouts are usually applied to JPanel, which is a lower level container (JFrame being the top-level container)
