Frames and modal/non-modal dialogs
Jan 9, 2004 7:54 AM

I have a swing application that has many frames and dialogs. Is it possible to make a dialog modal for some frames and non-modal for the others frames?

Thanks.

Its quite easy

first create your dialog

class Error_Dialog extends JDialog
//standard error dialog for displaying error messages
{
etc etc etc
}

ok then use code like this in your frame for a modal dialog

Error_Dialog ErD =new Error_Dialog();
Erd.setModal(true);

and use code like this for a non modal

Error_Dialog ErD =new Error_Dialog();
Erd.setModal(false);

hope this helps a bit

Thanks, but my problem is that I need to display the frames at same time.

i'm not sure i understand what you mean...
dialogs may hide underlying frames if you press alt+tab while a dialog has focus, but this occurs only if you created the dialog without a reference to the underlying (owner) frame (or dialog). if your dialog is created like this:
JDialog dialog = new JDialog(owner) ,
where "owner" is a JFrame or JDialog, then alt+tab will work fine.

i hope this helps...

You can only make one frame modal, AFAIK (in any language I've known). If you need two modal frames, can you possibly combine their GUIs onto one frame?

Hello,

You could launch your non-modal dialog in a separate thread. Code your dialog as a separate class and launch it with a SwingWorker.

I just finished an Open-Source application that does this, "BabyTalk Web", a SWING desktop text-to-speech that uses JAXB and Java Web Services. Check out how DialogList is launched.

Take a look at the following project on java.net https://jmodalwindow.dev.java.net/

It makes a window or frame modal to parent frame only.

Just add funtionality to add more owners to the modal window/frame to block and unblock more 'parent frames'.

Go to https://jmodalwindow.dev.java.net/ and download demo version 1.04.

Run the demo with: java -jar swingx_v0104_demo.jar

And choose option 'Open a modal window that also blocks second demo frame.'

This should demonstrate the functionality that you're looking for.
