pause until JFrame is closed.

[Tamu]

Hi,

I am not very good with JFrame yet. Somebody know how to pause a console until JFrame is closed by clicking the cross (right-up corner)?

It will do this by it's own work. To get a window without a console, we can use javaw

But I have a class to communicate with a user (with BufferedReader) in console.

That class just open picture of JFrame corresponding to user's command until "stop"-command is given.

I can open as many pictures I want, but if close one with a mouse, then my program will stop (console and JFrame(s)), although "stop"-command haven't given yet.

why are you mixing Swing and console apps here? It seems a poor program design. Also, are you setting the JFrame's setDefaultCloseOperation to JFrame.EXIT_ON_CLOSE? If so, don't. Or perhaps what you really want to do is show your pictures in a JOptionPane or a JDialog.

I am sorry, I am new to swing. I don't know all of it's property yet. So currently I am poor in taking advance of swing properties.

I have this code line in JFrame, so I think yes:

setDefaultCloseOperation(EXIT_ON_CLOSE);

Just in case. My JFrame have a subclass that extends JPanel to draw simple picture then add that component to JFrame.

Close JFrame will close my console, that is bad thing i don't want to happen :(

I don't think JOptionPane and JDialog are things I need, because I just want to show a picture that's all.

I found a dirty trick. It won't solve my problem but it make feel right =)
Dirty-trick : use "HIDE_ON_CLOSE" instead "EXIT_ON_CLOSE"

I don't thinik it sounds all that bad for get-going, all a gui is is what you are doing here without the cli ( command line interface - a "dos box" )

hide() and show() are fully legitimate, you may need to call paint or repaint or paintLater or whatever they call it today,....

Wait tilll you get to implementing

DocFlavor flavor = new DocFlavor(new String("application/vnd.hp-PCL",new String("String"));

You are in shallow waters brother, holler while you can.....

JOptionPane can show a picture more easily than a JFrame can with less overhead on your part. A JDialog can do most of what a JFrame can and is built to not close the app when it closes.
