I'm not sure if this has been answered or the correct way of phrasing it, but have had no luck in my search. I have 4 JFrame guis all in their own classes: a main gui and 3 others. I want to know if it is possible to display the other guis inside the same window without opening a new window and setting the first window to a false visibility? I'm able to call the other JFrames and make them display through a series of actionlisteners, but they open another window, making me have to setVisible(false) the gui window. I want to be able to have all the guis display in the same window without opening/closing windows. Thanks
You should not be creating separate frames. Just create separate panels and swap the panels.
See the Swing tutorial on How to Use Card Layout for more information.
Also, if you ever do need more than one window, you should be using a JDialog for the child windows. An application should only have a single JFrame.

how can I turn off the first jframe after clicking a jbutton to open a second jframe? just like this.
this is what I want to happen in my GUI:
It sounds like you are talking about implementing a 'GlassPane'
A GlassPane is a technique where you place a new RootFrame layer over the existing components and use it to
Absorb all of the mouse events to prevent them from interacting with the components
Shade the UI to draw more attention to the other modal window or other frame
You can read about creating a glasspane/rootpane
and there are plenty of examples of its usage
A Swing application should only contain a single JFrame.
For the child window you can use:
a modal JDialog for a complex window when you want full control over the components on the dialog.
a JOptionPane for a easy to use pre configured "confirm" dialog. See: How to Make Dialogs for examples.
i have 5 jFrames in my java project. And i want to make like a Main Menu.
I mean, i want that the program starts with a jFrame and when i click a button insteand of open the jFrame, all the elements like labels, buttons and tables are being shown in my principal jFrame.
And if i click other button the main frame will clean and charge other jframe.
It is possible? im programming with java jdk 8 and netbeans.
Thanks
Edit:
I think who marked duplicate didn't understand my question. I don't want to open or close the frame, or other frames, I want to load the structure and components of several in the same frame. Please read my question before you start complain that is duplicated

And that's a problem.

Yes this can be solved by getting the contentPane (usually a JPanel) from the JFrame whose content you want to display within the currently displayed JFrame, and making it the contentPane of the displayed JFrame, for example:
// create the new JFrame, the one whose content you wish to display
NewJFrame newJFrame = new NewJFrame();
// get its contentPane
Container newContentPane = newJFrame.getContentPane();
// add this content pane into the displayed JFrame
displayedJFrame.setContentPane(newContentPane);
// revalidate and repaint the JFrame so that its new data is well displayed
displayedJFrame.revalidate();
displayedJFrame.repaint();
// displayedJFrame.pack(); // and you might need to do this if sizes are way off
But this extra gymnastics is bulky, prone to bugs and unnecessary. You are painting yourself in a corner by having your class extend JFrame, forcing you to create and display JFrames, when often more flexibility is called for. In fact, I would venture that most of the Swing GUI code that I've created and that I've seen does not extend JFrame, and in fact it is rare that you'll ever want to do this. More commonly your GUI classes will be geared towards creating JPanels, which can then be placed into JFrames or JDialogs, or JTabbedPanes, or swapped via CardLayouts, wherever needed. This will greatly increase the flexibility of your GUI coding.
For this situation what I recommend is that you do that, that your GUI classes create JPanels, and that you add the ones that you want to swap to a JPanel that uses a CardLayout. And then whenever you want to show a different "card", call show(...) on the CardLayout object, passing in the JPanel that uses it, as well as the String key that was used when adding the "card" JPanel to the CardLayout-using JPanel. This is all well-explained in the CardLayout Tutorials.

I am making project with GUI. The thing is, that I have a button and what I need to do is that after clicking this button I need to change Frame layout. For example, like when you are installing some program and you click "next" button, the Frame layout changes and you can see some different content. Basicly, dynamic wizard.
I have tried use another Frame, but it opens in another window and that is not what I want. I want to open it in the same window.
Another thing I have tried is set visibility of these components I don't want to be displayed to false, but I find it unprofessional and it is overlook in making a desing, when I have components over themselfs.
So do you guys have any idea? Thank you.
Most of the times for a wizard like GUI, you should have JFrame and a set of JPanels. In each step you can pass the shared data as constructor arguments to each panel, and when you are making one of them invisible and make another one visible, you can get some date from the previous step panel and pass it to the next step panel(if needed).
It is very common that your panels extend the JPanel and have some argument in their constructor(s). You use these data for initializing your panel and managing the state of the overall progress.
There is no a total plan for all situations. So you should decide what to do which is best fit for your case.
Try not to have multiple JFrames.
Hope this would be helpful.
Is it possible to switch from screen to screen by just using one JFrame?
Do i need to create another JFrame or use JPanels and turn it on/off on button presses to create an illusion of jumping from screen to screen?
Or is there any other more efficient way to do this with other containers like
JDesktopPane, JLayeredPane, JInternalFrame and etc in netbeans ide?
What is the purpose and difference in usage of Swing Containers & Swing Windows?
When to use Containers and when to use windows?
By the way, i'm trying to build an Inventory System App Interface.
you can use JInternalFrame which is make how many child Frames you want in a JFrame and you can do also iconified,closable,resizable ... by make them true in child Frames until you can use JPanel instead of JFrame and switch between them(child Frame's) by just one click!
Edited------------
For Example:
JInternalFrame jInternalFrame = new JInternalFrame("Hello!",true,true,true,false);
jInternalFrame.setSize(160,200);
getContentPane().add(jInternalFrame);
jInternalFrame.add(panel);
jInternalFrame.setVisible(true);
And when you click the back button, it will return to the initial menu without popping out a dialog or changing the size or location of the window.
Sound like you can use a CardLayout. Read the section from the Swing tutorial on How to Use Card Layout for more information and examples.
I always wondered on how can I make a program with multiple JFrames. I mean I just want one class to handle all the GUIs and stuff but how can I effectively do this? A lot of tutorials say that we make JFrame by inheriting from JFrame. But what If I want many frames?
Ex:
Title of Application in one frame with some options
Menu is one frame
Main working application is one frame
Like in a game.
But I am not sure if I am pertaining to JPanel? I am completely puzzled with the 2. I just want one un-moving frame but basically the content of the frame is changing.
When I click START for example, it will change to the gaming style of frame.
you are looking for a JFrame with a CardLayout. Some background:
A JFrame is the physical window. It comes with a title bar and three buttons: minimize, maximize, and close. Think of this as a picture frame.
A JPanel is a "content holder" of sorts. Typically, you put your other components (buttons, animations, whatever) on a JPanel, and then slap that JPanel into a JFrame. Using our picture frame example, a JPanel would be the photo paper you put in the picture frame. The other components would then be the actual contents of the picture itself, and what you have at the end is a nice picture...or in your case, an application.
Setting the JFrame to utilize a CardLayout essentially lets you have multiple JPanels inside the same JFrame at once, while still only showing one at a time. So for your application, you would have (at least) two JPanels: one for the menu, and one for the game. When the app starts, you show the MenuPanel. When the user clicks "start", you switch to the GamePanel. The MenuPanel will be put in the background and will be inaccessible until you call it to the foreground again.
If, on the other hand, you create multiple JFrames, you will have two or more physically separate windows that can be dealt with individually. This can actually be kind of cool for game development. Although it takes more time to build and link the GUI for the second window, you can then have that window affect game settings in realtime (rate of fire, bullet strength, player speed, etc.)
I think that what you are after is the Card Layout:
A CardLayout object is a layout manager for a container. It treats
each component in the container as a card. Only one card is visible at
a time, and the container acts as a stack of cards. The first
component added to a CardLayout object is the visible component when
the container is first displayed.
You can see how it is used here.
This layout manager allows you to manage situations where your frame needs to be shared across various functions. In your case for instance, you could have a functionality to handle the settings section of the game and another one to handle the actual game itself.
You could then use the manager to switch between these particular items.
you can also use Desktopane() and InternalFrame() for multiple frame.
Internalframe quite similar to Jframe but it need to setVisible(true) or show() everytime.
Which ever IDE you are using, you can create multiple JFrames in the same package, and have separate codes for each of them.
If you want to link each frame, you will have to create instances from each JFrame. for example, if when the button is pressed, we need to invoke a new Frame (that we have already created)
NewJFrame1 frame1=new NewJFrame1();
frame1.setVisible(true);
then you can decide what to with your current JFrame.
eg : (Hide, Close)
