Swing JFrame : How to add a custom button to a jframe header

So far I got that we can remove the minimize/maximize etc buttons from a jframe (header).
How can I remove just the Maximize button from a JFrame?
How to hide the default minimize/maximize and close buttons on JFrame window in Java?
Is there a way to add a custom button in a jframe(header)? I am trying to extend the default available jframe buttons feature and add my own "always on top" into it. If this is not possible then I would like to add some pinning icon into the jframe (header) to replicate "always on top" feature for a jframe (or jinternalframe).
This feature that I am trying to implement is similar to what we see on a linux machines with gui which enable us to keep a folder always in top.
enter image description here

Here's a thought, how about instead, you remove the JFrame header:
frameName.setUndecorated(true);
And simply create your own using a JPanel. With this method, you can fully customize a JFrame header!

Making custom UI in swing

I need to make a custom ui which looks like the following image :-
I know how to change the button to that arrow shape and everything else.But I can't understand how to move those close ,restore and minimize buttons to the center and give them round shape (on Windows).
On Googling ,I found how to make custom shape windows but it doesn't meet my requirements.
Can anyone please tell me how to do this or any link.??

You will need to create your own title bar as another panel with buttons and then remove the window decoration on the frame.
JFrame frame = new JFrame(...);
frame.setUndecorated(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//This will close the frame and exit
To minimize and maximize, listen for button events and use:
frame.setState(Frame.ICONIFIED);//minimizes
frame.setState(Frame.NORMAL);//restores
See Frame.setState(int) for details.

JFrame window with sub components

So I have created this JFrame window which has a lot of items like JLabel, JComboBox JTextField etc… At the bottom it has a "next" JButton.
I want that when a user clicks the next button, everything on the screen should be removed and replaced with stuffs from other class that I have created.
I only manage to open a new JFrame window whenever I click the next button. Can somebody please tell me how to remove all items from the screen and replace them with items from another class.
Thanks. I am a newbie so please give me the easiest way possible.

This sounds like a job for CardLayout
You could create a base panel in the BorderLayout.SOUTH position of your JFrame that would have your navigation buttons and have a number of panels added to your main panel being managed by CardLayout.
See Creating Wizard Dialogs with Java Swing

While the systematic thing for it is using CardLayout, you can imitate it if you don't want to learn how to use it!!
Create a Panel, add all items except the next button to this panel. Use BorderLayout to put the panel on top of the next button in the frame.
Now when the user press the next button you remove the panel (jframe.remove(panel)). create a new JPanel and add it using the BorderLayout again on top of the next button.

How to disable iconified button in Menu bar in JFrame Window?

How to disable iconified button in JFrame Window ?
something like setResizable, but for minimize button

At First, you can use the method setUndecorated(boolean). It may disable the title bar and the border.
In the end, you will create the icon label and close button at your frame top or the others position.
But this way will lose the border look and feel for the frame. If you choose this way, you must create a lot of code.
In fact, If you could not use JNI, this way may be the only.

You could use a JDialog, which natively does not have a minimize button.
In fact, the minimize, close and maximize/un-maximize buttons are drawn by the Operating System itself. This means you can't really disable them within Java.
That's why my suggestion is to use a JDialog.

Minimize and Maximize JFrame on custom events in Java Swing

If I have two JFrames where one is the main JFrame, and the other one pops up when I click something. Now what I want is that when the new frame pops up, the main one should be minimized. Also when I click on this popup frame to close it, the main should be restored back.
Essentially I want to know, how can we maximize and minimize a JFrame apart from the default click operation. Is there any function for doing this on custom click for example?

1) setDefaultCloseOperation to NOTHING_ON_CLOSE
2) addWindowListener to JFrame
3) overrive windowsClosing() method with proper Action for iconify ...
4) don't forget to set to the JMenuItem/JButton System.exit(1), because in this form current JVM instence never gone from PC RAM or swap area until PC restarted or switch off
5) better would be to change 2nd. JFrame to the JDialog because in most cases is too hard manage lots of methods betweens two JFrames
