Hi all,

I use JavaHelp in my app to create a context sensitive help system. I've 
choosen to implement it by means of the "help" or "f1" key using 
HelpBroker.enableHelpKey method. This work perfectly well as long as I 
can have access to the component that has the focus.

How can I do it for JOptionPane.showXXX methods?

Example for a simple plaf chooser:

String selectedValue = (String) JOptionPane.showInputDialog(null,
         "Look & Feel to use:",
         APPNAME,
         JOptionPane.INFORMATION_MESSAGE, null, lfNames, 
lfNames[currentLFIndex]);

if (selectedValue != null) {
...
{


How can I associate a HelpBroker.enableHelpKey(...) on such a pane?

Many thanks

Bart

That is tough, because the showXxxxDialog() methods do not give you access
to the actual JOptionPane component.  In the showMessageDialog() case, if
you use a JComponent for a message, you can have it look at its parent,
but that does not work in other cases.

You can still use most of the functionality of JOptionPane, but instead of
using the showXxxxDialog() methods, create a JOptionPane component, create
the Dialog using the createDialog() method, and show that.  Basically, you
want to create your own showXxxxDialog() methods.  You can look at the
source code for those methods to see what needs to be done.

Thanks. This is what I was trying here now, but I was hoping that there 
was a more simple way...
