Any way to keep listening even if focus is lost ??

2008-10-08T11:26:02Z

Hi,
Do you think there's a possibility to keep listening for keyboard
events even if the component on which you've added the listener
looses its focus ?
Thanks.
Regards,

As far as I know your bean should be declared as:
@javax.ejb.TransactionManageme nt(javax.ejb.TransactionManage mentType.BEAN)
public class WebJpa ...

Surely using JDBC is faster than using the bridge... isn't it?

Use Connector/J. It's the most concise way to connect to a MySQL
database using JDBC.
Connector/ODBC would allow you to connect to a MySQL using the ODBC. For
a Java application you then could use the JDBC-ODBC bridge, but that
would be "a bridge too far".

So it's applying the JOptionPane "cheat" to arbitrary modal dialogs,
including ones it's never heard of before (novel JDialog subclasses, or
vanilla JDialogs controlled from another class).
I guess it sort of makes sense. But not documenting this at least for
SwingWorker.execute() seems boneheaded. Popping up a modal dialog box

You might need to checkout the particular source file first. Or put a
lock on it for editing.

Well it makes kind of sense.
Usually the modal dialog requests user input ("Do you really want to delete that?"), and the program will normally want to wait for the "result" of that dialog.

Yes. Been there as well :)
The way I have done this, was to spawn a new thread to open the modal Dialog, thus my "worker" code continued. I used EventQueue.invokeLater() inside the Thread's run() method to make sure the Dialog is realized inside the EDT. My modal dialog also has a Cancel button, and it works nicely.

Really? What idiot made that boneheaded design decision -- and,
moreover, didn't document it anywhere?
I'll see if simply swapping the setVisible(true) to after the execute()
fixes things. I definitely don't want the UI to receive input events
while this work is going on, but I don't want it to hang (not paint

No, it's the upper left corner of the JFrame that ends up centered on
the screen, rather than the JFrame ending up in the upper left corner of
the screen.
