I want to create a JTabbedPane in a Visual Class using the Visual Editor in Eclipse.
I selected JTabbedPane from the beans menu on the toolbar.
I next clicked on the class to drop it in. So far, no problems.
But wait, no tabs are showing up.
The tutorials on the web say to drop a component into the TabbedPane and the tabs will show up. I dropped a JLabel and no tabs showed up.
Deleted the JLabel using the design window. Dragged a JTextPane, still no tabs.
I drag a JTextfield, onto the TabbedPane (without deleting the JTextPane), still no tabs showing.
I set the "tabs_text" properties of the JTextField and the JTextPane. Still no tabs show up.
Also, the components are not showing on the TabbedPane. It's like a gray whole that just swallows things and no images are reflected back.
Anybody have a step by step tutorial, instructions or something similar for how to put a JTabbedPane onto a Visual Class and also components into the JTabbedPane? Pictures would be very helpful.
Do I have to use NetBeans or hand-code the JTabbedPane?
Note: I'm trying to create a tabbed pane (or notebook in other GUI terminology) with one tab for person's address and another tab for phone numbers.
You should be able to create a JTabbedPane with the editor. But since you asked:
Do I have to use NetBeans or hand-code the JTabbedPane?
I will answer that with no you don't. But I would very highly recommend hand-coding the entire GUI. Visual Builders are nice for prototypes but produce much pain and bloodshed for those who have to maintain the code. Once you get past the Swing learning curve, you will find that Builders only limit your ability.
The TabbedPanel is showing up. Here's what I did:
I created a separate class,
Residence, derived from JPanel. Added
all the labels and fields.
Modified the addTab statement to
add the new panel.
Changed the add method to use 2
parameters, not 4.
Removed all "ve" comments, placed in
the code by the Visual Editor.
I don't know which, any or if all of the above was necessary, but that is what I did and now the TabbedPane is showing in the Visual Editor.
Looks like the Visual Editor may be more useful to show what the form looks like rather than as a tool to build them.

I'm trying to make all my components to resize properly with JFrame Netbeans, but if I put the auto resizing to my components, it has like a margin between them, and if I try to put them together, it messes up the components , and I need them to be touching each other.
Thanks!
Double-click on the extra space between the components: it should open a dialog where you can change its size.
You can also click the extra space, and use the mouse wheel.
Netbeans form designer is very powerful and handy when you master it, but it requires some effort at first, especially for large user interfaces. If not already done, take some time to follow this tutorial: https://netbeans.apache.org/kb/docs/java/quickstart-gui.html
Also, if your user interface is large, it's better to break it in several smaller panels. You can design each panel independently with the form designer.
I have a task to create a desktop app and I decided to use Swing as I have some experience with it. Also I am using Intllij and I noticed it have a form creator visual interface so I want to use it because its easier.
Samples of my interface is attached here. Its not hard but I dont know which controls to use in order to make something like this. On startup I need to have some text on the right side of the window, then on press on different button on the left to change that text with some other controls like fields labels check boxes etc. Its bit like tabs but I cannot use the JTabbedPane because it become with too different design. Could you advice me which controls to use and how to use them in order to achieve this design ?
Here is the design:

It isn't easier as you end up spending time learning the IDE instead of learning Swing. Any code that is generated will not be maintainable if you ever need to switch to a different IDE.
Learn how to create/maintain the GUI forms manually.

Start with the standard BorderLayout for the frame. Then you create a panel with your buttons to display on the left. You create a second panel that uses a CardLayout in the CENTER of the BorderLayout. Then when you click a button you swap the panel that is displayed in the CENTER.
Read the section from the Swing tutorial on Layout Managers. There are sections on:
How to Use BorderLayout
How to Use CardLayout
to get your started with working examples.
If you are creating a commercial application(rather then as a leaning experience) consider using JIDE Common Layer as the MultiplePageDialog provides the functionality you seem to be describing:
In this case a series of buttons on the left controlling a panel on the right
I'm starting using java with NetBeans IDE. I'm using drag and dop GUI, it's so easy to use, but I got a problem. I'm writing this code at the contructor:
JComboBox combobox=new JComboBox();
combobox.addItem("Apple");
combobox.addItem("Banana");
for(int i=1;i<=10;i++){
combobox.addItem(i);
}
just right above initComponents(); hoping that my new combobox will shown when I run the project, but it doesn't. Did I do something wrong? Thanks in advance
Yes, you are creating a JComboBox, and yes, you are adding items to it (numeric and int -- that's a problem, but that's a discussion for another day), but no, you're not showing any code where you add this newly created JComboBox to a component that is displayed in the GUI. To display a component in a Swing GUI, it must be created and added to a component that is ultimately displayed in a top-level window, in the "GUI".
So this begs the question, how do you add your created JComboBox to your GUI that you've created with drag and drop code? One way: you could add it to say a JPanel that's already in your GUI, but you will need to do this after initializing components, usually this means after the constructor calls initComponents(), and you'll also need to make sure that this JPanel uses a layout manager that makes it easy for it to accept new components (this means most of the layout managers except NetBean's default layout, GroupLayout).
There are other issues, such as whether or not the container holding your JComboBox is large enough to display it, but the best suggestion that I can give is for you to go through the Swing tutorials, and hit especially hard the layout manager section. You can find links to the Swing tutorials and other Swing resources here: Swing Info.
I have developed a simple music player in Java which can play any given playlist or simple mp3 song.
For now i have worked all things out in plain JPanels. GUI doesn't look neat.
I need to revamp the GUI using tabbed pane. How this can be achieved using existing JPanels without affecting current functionality?
Also, i am not able to figure out shall i go for Tabbed Pane or Card Layout?
http://docs.oracle.com/javase/tutorial/uiswing/layout/card.html
Because a tabbed pane provides its own GUI, using a tabbed pane is simpler than using the CardLayout class.
"Also, i am not able to figure out shall i go for Tabbed Pane or Card Layout?"
It really depends on your preference of the look of your program. The two layouts perform very similarly, though CardLayout is a little bit more code, though at all not difficult. If you don't want the tab look, which I don't see why you would, for a game, then go with CardLayout
"How this can be achieved using existing JPanels without affecting current functionality? "
You need to create separate JPanel for each containment of whatever components you want in each tab. Then just add those JPanel to the JTabbedPane. It shouldn't break any functionality, just the look. Components from another panel should not be affected, you just won't be able to see any changes made, unless that other panel is in view.
If you want to go with CardLayout you can look at the tutorial
I have a question about Netbeans GUI Editor.
I created this test application containing a MenuBar using the GUI Editor. However I need to Add another swing component (Let say a Jbutton) to the frame that contains the MenuBar directly from the code and not using the GUI Editor.
I Succeeded in adding the Jbutton but I found that the only way to do it is to change the layout from the code. The result was not what I expected since the menuBar added by the GUI builder changed it layout also.
So briefly I want a way to add The Jbutton from the code without affecting the original components added using the GUI Builder.
The GUI builder uses the Group layout. if you want to preserve the layout of the original components you need to stick to this layout. Codeing by hand in this layout is awkward but the following link will help.
http://docs.oracle.com/javase/tutorial/uiswing/layout/groupExample.html
You'll need to add your button, using the addCompenent method, to groups in both the horizontal group and the vertical group.
Good luck!
