I'm beginner with Netbeans and GUI. I want to create JTabbedPane by click on one button and wants also that tabbed pane name will be the name of the button: I used this code but nothing appears!
JTabbedPane jtp1=new JTabbedPane();
jtp1.setVisible(true);
jtp1.addTab(jButton1.getName(), jPanel6);
I want also to add this tabbed pane to a panel and it will be the same size of the panel.
I highly recommend working through this tutorial from Oracle before you spend a lot of time figuring out how to make it work in netbeans. At some point you will have to understand what netbeans is doing to the code and why... it is a lot easier to get that info first and then use the IDE to help shortcut it then to try and figure out where in the mess of code the IDE generated you should start learning.

I want to create UI for my program with netbeans but I don't know how to create a UI that when user change the size of program window( maximize or other sizes ) component of the program change sizes for match to that program size.
I want to create a GUI for aria2c download manager like Google Chrome that has one button to change state from HTTP to FTP or metalink and so on and a textField for import users download link and a button for settings like Google Chrome. Below this toolbar I want to show things that user want to download like IDM. That IDM show name and status of things that user want to download. Please suggest how I can create this GUI and which layout manager is comfortable for creating this GUI. Thanks very much.
You can use either GridLayout or BorderLayout. Also read this: Using Layout Manager
Agree 100% with Harry. Also:
Avoid using NetBeans default GroupLayout
Learn about nesting JPanels each with its own simple layout to in effect nest layout managers and create complex layouts.
Probably avoid usingGridBagLayout early on when learning to use layout managers and use the more simple ones if possible. Consider using MiGLayout if you need a complex gridbag-like layout and nesting of simple layouts doesn't solve the problem.
If stuck, post an image of your desired GUI layout and your latest code attempt, and we'll be able to give you more specific advice.
So I made a JPanel and a JFrame using the Design functions in NetBeans and when I try to drag the panel onto the JFrame, I get the error "The component cannot be instantiated. Please make sure it is a JavaBeans component."
What I did was create an empty Frame and then create the Panel and put it all together using the panels, buttons, and text fields. I didn't modify the source code or anything. Is there some kind of code I need to add into the panel to make it work with the JFrame? Or perhaps I missed a step in the design tab? I've included a picture that shows exactly what it is I made.
jpanel
Clean and build the project (and sub projects as required).
If you're using Netbeans 7+, you can check the messages.log found in C:/Users/{username}/AppData/Roaming/NetBeans/{Netbeans version}/var/log and check for the exception that caused the problem.
I think the new 7.2 beta reports the problems to the user now (thankfully).
I am trying to learn Java Swing with the aid of the Netbeans IDE. Following this tutorial, I find myself stuck when I try adding a Panel to a JFrame.
The Panel, or any other component from the Swing Container, does not add to my design view.
I have tried dragging and right-clicking the component without success.
When I right-click the Panel component, I get various menu options including "paste item" but it is greyed out and inactive.
Just click on the palette "Swing Containers" Panel button. In 7.2 and 7.2.1 it is a toggle switch. Then go to your JPanel and you will see your new JPanel moving along with your cursor. Move it to the location you want to have it and click again. Then you can resize it to the dimensions you like...
Netbeans IDE is an excellent production tool. If you are in the learning phase however, it is always better to avoid using powerful GUI-editors, in order to gain a better understanding of the concepts. You can do that using simple text editors.
You will find these links helpful: The Swing Tutorial, Java2s tutorial and Java Beginner Tutorial. And certainly you can ask Stackoverflow if you get stuck at some point, or want an opinion

I have build an application using the Netbeans Wizard Framework as outlined here and here. I have my application working properly, but the problem I have is that the application does not show in the windows taskbar. I am pretty sure the problem is that the Wizard Framework uses a JDialog instead of a JFrame, but I can't figure out if that can be changed.
If anyone has experience with this framework, please let me know if it can be made to appear in the taskbar.
Changing is quite easy.
Open the form in NetBeans.
Change extends javax.swing.JDialog to extends javax.swing.JFrame.
Save the file and close it.
Reopen the file.
In designer mode, make a change. I usually just change the name of a component.
Save the file.
Undo the change and save the file again.
You should be all set.
Wizard Framework uses a JDialog instead of a JFrame, but I can't figure out if that can be changed.
don't use more than one JFrames, this's road to the hell, you cann't to setToFront, setOwner, iconify, etc ...
use JDialog or JWindow instead with parent to the one single JFrame
use undecorated JDialog, with setModal() or is possible to set various ModalityTypes too
If anyone has experience with this framework, please let me know if it can be made to appear in the taskbar.
this Swing Framework is long time depreciated
you can use SplashScreen repeatly instead of JDialog/JWindow
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)
