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 creating an interface composed out of a box layout which contains panels inside every space.
In this specific case I've got a "cascade" of panels, the first is supposed to be a panel with a FlowLayout as layout manager, underneath it there's a GridLayout and under it there's supposed to be another label.
The thing is that I'd need the first panel to dynamically resize as the window get resized itself.
Here's the problem: I need the first panel to have a specific size in relation to the absolute size.. the thing is that I can't set my preferred size.. in the class I do the following but the panel stays the exact same size as before..
this.setPreferredSize(new Dimension(windowWidth, 50))
I'll send the code as soon as I get home, for now the situation is the one written above.
I need the first panel to have a specific size in relation to the absolute size
Your main panel should be a BorderLayout (which is the default layout of a JFrame), not a BoxLayout.
Then you add the panel that needs to be a specific size to the BorderLayout.NORTH of the frame.
Then your second panel can use a BoxLayout and add this panel to BorderLayout.CENTER of the frame. Now this panel will get all the extra space as the frame is resize.
So I was trying to google how to set a default size to JButtons so that they don't grow as the JFrame is resized. I didn't see a setDefaultSize method but the closest one I could find that does a similar job is setMaximumSize(). However, it doesn't seem to work in my situation and I'm guessing it's because I'm using Grid Layout for positioning my buttons in the frame, here's a small piece of my code:
rightPanel.add(ButtonA);
rightPanel.add(ButtonB);
rightPanel.add(ButtonC);
outerPanel.add(leftPanel);
outerPanel.add(rightPanel);
getContentPane().add(outerPanel);
Here's a picture of what happens:
I would also like to have my buttons in the middle of the right panel when I'm resizing (just like they are now but a lot smaller). Any idea of how I can fix this? I'm assuming that I have to use another layout or something.
Thanks
EDIT: I modified my code to use BoxLayout but it does not seem to put the buttons in the middle. The X Alignment is working but Y Alignment is not doing anything:
ButtonA.setAlignmentX(CENTER_ALIGNMENT);
ButtonA.setAlignmentY(CENTER_ALIGNMENT);
ButtonB.setAlignmentX(CENTER_ALIGNMENT);
ButtonB.setAlignmentY(CENTER_ALIGNMENT);
ButtonC.setAlignmentX(CENTER_ALIGNMENT);
ButtonC.setAlignmentY(CENTER_ALIGNMENT);
JPanel rightPanel = new JPanel();
rightPanel.setLayout(new BoxLayout(rightPanel, BoxLayout.Y_AXIS));
rightPanel.add(ButtonA);
rightPanel.add(ButtonB);
rightPanel.add(ButtonC);
outerPanel.add(leftPanel);
outerPanel.add(rightPanel);
getContentPane().add(outerPanel);
EDIT2: Fixed with vertical glue.
A GridLayout will always resize the components to fill the space available.
Try using a vertical BoxLayoutinstead. See the section from the Swing tutorial on How to Use Box Layout for more information and examples.
Encapsulate each JButton in a JPanel with a FlowLayout, and then add those FlowLayout JPanels to the rightPanel instead of the JButtons themselves. This will allow you to keep your evenly spaced buttons, but won't make them expand to take up the entire space that the parent container has available.
If you don't want them evenly spaced, but to be three consecutive buttons one after another top down, you can make the right panel have a BorderLayout, add a sub panel to the north area of the BorderLayout with the original GridLayout that the right panel had, and then add those FlowLayout panels containing the JButtons.
I have a UI requirement in java swing wherein I need to achieve the below:
The 2 buttons on the top are placed in a JPanel. I need to draw a line through the center of that panel, upto the beginning of the 2 buttons. The panel below is a container of panels arranged in a card layout. As and when the button is clicked, the card is switched showing another panel.
So in all respects this looks like a JTabbedPane, with one difference, the tabs are buttons arranged in the center of the tabbed pane. I need this difference for the UI I am building.
As of now, the buttons and card layout panel, looks like the below
As you can see, the buttons and panels appear and look separate, instead it would be nice if they are made to appear like they represent one unit.

Put the Border around the outer panel. That is use a panel with a BorderLayout. This panel can have a LineBorder. Then you add your button panel to the NORTH and the panel with the CardLayout to the CENTER.
The line won't be drawn through the buttons but the buttons and panel will appear like they represent on unit.
I have kept a JButton in the bottom middle part of my JFrame. Now whenever I resize the window the JButton should be repositioned (in the new centre) depending on new resized window. Can anyone tell me how to accomplish this. Thanks in advance.
Components in Swing are rendered according to the frame's layout manager. The default layout manager is BorderLayout, which divides the frame into five logical parts: North (up), South (down), East (right), West (left) and Center (everything in between). Components are centered by default.
You can create subframes for each part, and give them the a similar layout manager, or a completely different layout manager. in your case you'd want to create a new subframe at the South position of the main frame, and put your button in one of its North, Center or South positions.
Hope this helps...
1) Create a JPanel usign a FlowLayout with "center alignment" and add your JButton to the panel.
2) Add this panel to the "SOUTH" of the content pane which uses a BorderLayout by default.
i would take a look at LayoutManagers
BorderLayout would do the trick
