[@jerry04SAVED]

Hello friend, excuse the trouble first of all these video tutorials are helpful. As you can disable the close button of the window JFrame. In this video the Close method to close the JFrame not be disabled when you disable the close button of the window.
Greetings Friends ...

[@channsothun9431]

I normally use hide method to close a frame, but I think it is not the right way to actually close a frame because that frame is just invisible but not actually close. Any better idea?

[@mtxx80]

I think better and easier would be:
public void close() {
this.setVisible(false);
this.dispose();
}

[@aryastark1833]

dispose doesnt work when you have a static class

[@serahganjawala]

thanks
i used this and it worked

[@javadeveloper-o5j]

[@Swiftkillah1300]

this videos helped me with the first form but more the second form links to a third form then this same function closes everything. How do you make it work when there are more than 2 levels of forms?

[@waqarjamali]

use f.hide(); inside the action of the login

[@joeyczo5008]

Thank you !!!

[@AboMSGL]

Thank yoy,
You should be attention to change the state of fram in the runtime also

[@WaleedMdAlHasanOmer]

Dear
This code instead of closing the current window, it closes the whole application.
I used instead this line:
this.setVisible(false);

[@MaxSandberg]

You're wrong it doesn't

[@Mhtwy]

You. Are. Awesome! Thank you very much that helped alot.

[@kanananonim3132]

How to not closing main jframe when closing new. I mean that, when we run the program, there is a button on that jframe, when I click that button new jframe will open, and when I close this new jframe the old one also will be closed. but my wish is that not closing the old jframe until I close it myself.

[@natasuah]

I tried but is not working. I have imported 'import java.awt.event.WindowEvent;'. This is what i have in my method. " public void close(){
WindowEvent winClosingEvent=new WindowEvent(this,WindowEvent.WINDOW_CLOSING);
ToolKit.getDefaultToolKit().getSystemEventQueue().postEvent(winClosingEvent);

}"
Is complaining of no suitable constructor found for windows Event.
Could you help me? Thank you

[@anamikaahmed4887]

simply use this.dispose() on the method of the button.
You don't have to write this much code.

[@RenXenpai]

Lol you saved me thank you

Yeah I have. I only use dispose() . Hey thanks

It is a DATA_MEMBER, which comes under class WindowEvent.

thank you! very useful >O

[@mukulbadhan5336]

how to close previous window when using framename.main(argv);

[@riadfaical]

ty bro !!

[@lifeoftomi_]

If you use eclipse,in your actionPerformed method all you need to write is yourFrameName.hide(); so for me that was frmLogin.hide();

[@lifeoftomi_]

Seeker but if your class already extends JFrame, you should be able to call hide(); or use this.hide(); still in the actionPerformed method and before initialising the new frame.

[@lu1sner193]

Thanks Bro !

[@trunghieunguyen7153]

thank u so much !!!

[@manishpaul_]

or just add "dispose();" before opening another frame.

[@Bluemangrup]

I did the public void close exactly like the video:
public void close(){
WindowEvent winClosingEvent = new WindowEvent(this,WindowEvent.WINDOW_CLOSING);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(WinClosingEvent);
}
But it says it can't find symbol: class WindowEvent
Can someone please explain why?

[@sureshnaame6982]

write package "import java.awt.*;" & "import java.awt.event.*;". Because WindowEvent comes under these packages.

[@waqarjamali]

use this.hide();

[@Bluemangrup]

Thank you!

[@riskinovasaputra4018]

Thank you

[@crisalide98]

Thanks!!!

[@markjason2]

Or you can use
ThisFrame.Dispose();
:D

[@sanskarsingh9538]

haha i wonder why a person who already knows would be here. thanks though

[@joanasflute]

YOU ARE AN ANGEL

[@SuperAlphabetagama]

Why not just use this.setVisible(false);

[@harveybarcelona7252]

is there another method to close only a frame because your method is too long :V

[@loooooooooool77]

didnt work :/

[@kanananonim3132]

How to connect with you? do you have facebook, skype or any?

[@deepakkumar-pk4kt]

thanks,...

[@Shadrech]

Don't put it in the public frame() {... } constructor. Put it outside and it will work:
e.g.
public class MainFrame extends JFrame {
public MainFrame() {
....
}
public void closeFrame() {
WindowEvent winClosingEvent =......
}
}
Being u asked this 3 months ago I'm probably wasting time answering..u must hav found the solution in these 3 months?...

[@feero9680]

7:00

[@lighttech7750]

verty esay methode tankes

[@XC3rocks]

it closes out both windows

[@bbd9106]

just set the first frame property to dispose after this process shown in video

[@EMINEMisnr1]

the easiest would be this.setVisible(false);

[@Nousa460]

:) God bless you (y)

[@jeanrodrigues6249]

Whatsup

[@fifatemple4781]

Pls stop being annoying my big brain cannot follow ur methodolgical proceedings with the Java Graphical User Interface code so pls halp and extand my mind

[@Hydraxon3200]

btw. it is easier to just write dispose(); before the code for opening a new jForm...for example dispose ();
new jForm().setVisible(true);
xD
;)

[@Tomahoop]

at Login.java (or whatever you named it):
if(rs.next()){
JOptionPane.showMessageDialog(null, "Username and Password is correct");
rs.close();
pst.close();
patient_info s = new patient_info();
s.setVisible(true);
this.dispose(); //use this line of code which makes this entire video pointless
}
