it's simple just follow the below code:
First import these two files below
import java.awt.event.*;
import java.awt.*;
then write the method for close
public void close(){
WindowEvent winClosingEvent = new WindowEvent(this,WindowEvent.WINDOW_CLOSING);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(winClosingEvent);
}

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.

@jerry04SAVED 11 лет назад

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 ...

@WaleedMdAlHasanOmer 10 лет назад

" 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

@lifeoftomi_ 9 лет назад

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

@lifeoftomi_ 9 лет назад

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.

@anamikaahmed4887 7 лет назад

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

@RenXenpai Год назад

Lol you saved me thank you

@iondhai6074 3 года назад

@manishpaul_ 7 лет назад

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

@Bluemangrup 7 лет назад

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 7 лет назад

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

@waqarjamali 7 лет назад

use this.hide();

@Bluemangrup 7 лет назад

Thank you!

@markjason2 9 лет назад

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

@harveybarcelona7252 7 лет назад

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

@loooooooooool77 11 лет назад

didnt work :/

@Shadrech 10 лет назад

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?...

@bbd9106 6 лет назад

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

@Hydraxon3200 12 лет назад

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

@EMINEMisnr1 11 лет назад

the easiest would be this.setVisible(false);

@Tomahoop 6 лет назад

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 }
