I'm using Netbeans.
I use Netbeans to create a Jframe and drag and drop a JLabel to Jframe.
I want to add a JLinkButton (I use zfqjava JLinkbutoon) to Jframe and to JLable by using code(but not drap and drop) but it doesn't work.
Here is my code to add JLinkButton to JFrame
this.getContentPane().add(linkButton);
and here is my code to add JLinkButton to JLabel
lblbackground.add(linkButton);
You can't add the same JLinkButton both places. It will only appear in the last place you add it. Instead create to instances of it, one for each place you want to put it.

I not able to getting the proper JinternalFrame. In my application in main JFrame I have one disktopPane that contains GridLayout.
When I call JInternalFrame by click on button I am getting that internalFrame, but that fix to a particular Grid box only, and I am not able to maximize the InternalFrame.
How can I solve the probleam?
below is my GUI:
I am doing Code through NetBeans.
How Can I fix this issue ?
Don't use a jdesktoppane. Use a normal JFrame with a JPanel with your components and the gridbaglayout.
For the windows floating above the main JFrame use new JFrame's with setAlwaysOnTop(true) and make sure they have your main JFrame as root.
I have a very big Frame made with Netbeans GUI Builder. And of course, made by default all inside one file, called JFrameTest.java.
Now I want to modularise my code. I have a JFrame containing a JTabbedPane and inside a lot of JPanel.
What I want is to have for each JPanel inside the JTabbedPane a specific java file, with inside actions, subviews, etc ...
It is too late now ?
I means, all my Panel have subviews like JTable, Button, etc .. and are inside the JFrameTest file.
There is not a way to say : Move the Panel and its subviews inside this CustomJPanel class, etc.. ?
I'm making a JFrame that contains a lot of JButtons and JTextfields which contain data from a database. In the design everything is okay, but when I run my program the JButton and the JTextfield change their places and I don't know why.
Here is a screen shot from the design window and the run window:
Seems like you have aligned the textfields to each other and the buttons too. But you should have aligned one button to one textfield. One way to do this would be to use a GridBagLayout instead of the FreeDesign option in NetBeans. To do this right-click onto your frame and select Set Layout>Grid Bag Layout.
You can then right-click again and select Customize Layout... in order to place your components as you wish.
I'm new to Java and actually designing the GUI for an application.
My main is a JFrame with 5 buttons and 1 panel which will have the "content", for the first button for example, I've designed a Jframe which has a JTabbedPane.
Now I would like to know how can I incorporate the content from that frame to the "content" panel when clicking on the button ?
I tried to use .add but I get:
java.lang.IllegalArgumentException: adding a window to a container
(seems we can't add Jframe to Jpanel).
I also tried the setVisible way but it doesn't meet what I need since it will hide the panel completely and I will get a tiny window with the buttons.
![Jframe content][1]
![Main Jframe with buttons and Jpanel to show the jframe content][2]
The code is generated by netbeans, and I forgot to mention that I did research on adding a Jframe into another Jframe but here isn't my problem at all.
I tried by changing the Jframe by JInternalFrame but clicking on button doesn't do anything.
Button has
contentPanel.add(new GestionUtilisateur());
So basically when you click on the "Gestion Utilisateur" button for example, you get that JTabbedPane that has to appear in the content area (which is blank here)
You should not be putting JFrames inside JPanels. If you have multiple panels you would like to display, depending on something like a button, look in to LAYOUTS.
In particular, it sounds like a CardLayout would work well for your needs. CardLayouts allow you to swap which panel is displayed in a frame by bringing it to the "front" of a list of panels. This would let you display your JTabbedPane on one button click, then click another to change the content pane.
JFrame can not be added in a JPanel.
use JInternalFrame
Make and hold references to JPanels containing your content. A JFrame is really just that, it's a frame (though you can add a single component to it).
You can't add a JFrame to a JPanel. If you want multiple components to be visible use layouts such as BorderLayout, GridBag, etc. Check out some of the Swing layout tutorials here.
Content should be designed as JPanel (you can design it with drag&drop just like JFrame) but if you really have to put a JFrame to JPanel for some reason, you can do it by
myJPanel.add(myJFrame.getContentPane());
however i would suggest modification of your program.
Building a Java GUI application using Netbeans IDE. I have created a JPanel in it. After adding a lot of fields, I want to also add a JscrollPane to it. I have found that if we right click on the pane we have an option to Enclose it in a container that can be Scroll pane or Split pane etc.
The problem is, that the enclosed button is greyed out when I right click on the panel. How should i fix this ?
I had the same issue. After experimentation, it appears you can only use Enclose In if the Layout is set to Free Design.
However, an alternative method I discovered to accomplish the same thing is to create the empty JPanel and the components you want inside it, all at the same level in the TopComponent. Then drag and drop the components you want into the JPanel, using the Navigator window that shows the component hierarchy.
For example, here I've created a JPanel and a JRadioButton as siblings, and then I drag and drop the JRadioButton inside the JPanel, so that the JPanel is the parent.
Result:
