I have a JFrame that has 3 components on it.
The design is like this:
My problem happens in the JTabbedPane.
The pane begins off with a settings panel, which is added to it when the whole JFrame loads up. Then, when the user connects, a new tab is added to the pane (the actual chat panel).
When that tab is added to the pane, it overlaps the bottom of the java applet loaded from the local file, which is NOT what I want to do. Here is how it looks:
As you can tell, the bottom of the highscores and java applet has been cut off. How do I resize the JTabbedPane to make it resize towards the bottom, instead of upwards?
Call pack() after adding a tab to the pane.

I'm wondering how I can add (what LayoutManager should I use) to make the app automatically adjust the components to the current size when full screen mode is enabled or even when the frame is stretched.
Currently this is what the application looks like, when you enable full screen mode the components are static.
UPDATE: I'm pasting pictures so you can get an idea of what I wrote.
Component layout in IntelliJ: layout
The current design in the small window looks ok: current design
Appearance if we enlarge the window (window zooms in, elements are static): full screen
So I'd like the components to automatically resize to the current window when fullscreen mode is enabled.
Okay. I suggest the following design:
your mainPanel, that you assigned as contentPane for your frame gets a Borderlayout.
In the North, you put a panel with a label or just a label, with Allignment X to the left.
the West gets a panel I suggest we call WestPanel and the East gets another one, which I call EastPanel.
WestPanel gets a Boxlayout or a Gridlayout. If you use Gridlayout, you can use 2 Grids wide and for each line one grid depth. You then can add all the labels in the left column and the textfields on the right.
Or you can make panels, with Borderlayout, labels to the West, textfields to the east, and pile them with emptyBorders ontop of each other. I suggest using a method for that.
The EastPabel gets a Tabbed Pane inside of it. Each tab can have its own layout manager, depending on what you want it to be in the end.
Does this help you?
Problem is when i create GUI in jFrame window on screen and run the program later it in full screen using
setExtendedState(MAXIMIZED_BOTH);
it do not show up like it looked in that window see the red bordered area
Components appears in one corner of screen or only at a small part in center depending upon layouts and rest is empty space like this
I want JFrame window (see the red bordered area in first image) which is showed while creating GUI to represent my whole screen so that i can know how it will look when i run it in full screen.
Change the layout manager, may be using a combination of BorderLayout and GridBagLayout
These will provide you with a means to define how the components are positioned and sized within the parent container
See Layout out components within a container for more details
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.
I have an open-source java swing application like this:

You can see in the screenshot, there is a JPanel divided into two area, left and right area. The left area has many text links. When I click the SLA Criteria link, it will pop-up the SLA Criteria window. The pop-up window is JFrame object.
Now, I'm trying to put the pop-up window into right area of the JPanel, so that means no pop-up window anymore, i.e. when I click the SLA Criteria link, its contents will be displayed at the right area of the JPanel. The existing content of the right area of JPanel will not be used anymore. The concept is just same like in the java api documentation page: http://docs.oracle.com/javase/6/docs/api. You click the link in the left frame, you'll get the content displayed at the right frame.
The example illustration is like this:
(note: it's made and edited using image editor, this is not a real screenshot of working application)
http://i48.tinypic.com/5vrxaa.jpg
So, I would like to know is there a way to put JFrame into JPanel?
I'm thinking of using JInternalFrame, is it possible? Or is there another way?
UPDATE:
Source code:
http://pastebin.com/tiqRbWP8 (VTreePanel.java, this is the panel with left & right area divisions)
http://pastebin.com/330z3yuT (CPanel.java, this is the superclass of VTreePanel and also subclass from JPanel)
http://pastebin.com/MkNsbtjh (AWindow.java, this is the pop-up window)
http://pastebin.com/2rsppQeE (CFrame.java, this is the superclass of AWindow and also subclass from JFrame)
Instead of trying to embed the frame, you want to embed the frame's content.
There is (at least) one issue I can see with this.
The menu bar is controlled by the frame's RootPane.
Create you're self a new JPanel. Set it's layout to BorderLayout.
Get the menu bar from the frame (using JFrame#getJMenuBar) and added to the north position of you new panel.
Get the frames ContentPane and add it to the center position of the panel.
There is undoubtedly countless other, application specific issues you will run into trying to do this...
No, you don't want to "put a JFrame into a JPanel" and your illustration above doesn't demonstrate this either. Instead it's showing a subordinate window on top of (not inside of) another window. If you absolutely need to display a new subordinate window, I'd recommend that you create and display a JDialog. The tutorials will explain how to do this, or if you get stuck post your code attempt and we'll help you work with this.
Edit 1
You state:
I need to convert from the pop-up window style into the jpanel content style. It's just like the java api documentation page style: docs.oracle.com/javase/6/docs/api When you click the text in left frame, it doesn't show any pop-up, right? The content is displayed at right frame directly. So that's basicly my goal. The source code is quite big. I will try to paste the source code if possible.
What you are looking for is to simply implement a MouseListener in a JList or JTable, and when responding to the click get the content based on the selection made. This has nothing to do with placing a JFrame in a JPanel and all to do with writing the correct program logic. Again, display it in a modal JDialog -- but that's all secondary to your writing the correct non-GUI logic. You're really barking up the wrong tree here. Forget about JFrames, forget about JPanels for the moment and instead concentrate on how you're going to extract the SLA Criteria data when it is clicked on.
Edit 2
I think I see what you're trying to do -- instead of JFrames and JDialogs, use JPanels and swap them using a CardLayout which would allow you to swap views.
I had skimming the source codes, I saw that the AWindow.java has internal panel (APanel.java) to hold the window's content, and it also has a public method to return the content panel object (getAPanel()). With this, I can use it for fetching the window's contents into other container.
Finally, I decided to use JTabbedPane in the right area of VTreePanel for displaying the pop-up window's contents.
You cannot put a Jframe into a JPanel. Instead you should try to create a separate panel that has functionalities like your JFrame and embed that into your JPanel.
Since you can put a JPanel into another JPanel but not a JFrame into another JPanel
I tried to drag a JSplitPane from the Palette in NetBeans but it always shows up on my JPanel as two separate panes with left and right buttons on them.
I could not do anything with the buttons. They were not even components on the Pane. What is going on? How could you make it like normal empty two split panes with nothing one them?
The buttons are just placeholders. First you resize the pane(including those buttons) to what size and position you desire. Then, just drag a JPanel (or any other component) from palette, and drop it on the any of the buttton. That button will be replaced by the JPanel (or component). Then you may do anything as you normally do with JPanel (or that component).
