#4002 — Keyboard focus getting lo

  To: comp.lang.java.gui
I have an applet that loads a component that uses any number of other 
components internally.  When it is first running the component gets the 
KeyPressed events that I want it to, but then after doing anything with 
the mouse, it no longer gets these events.  I think that the focus must 
be on one of the sub-components, but I don't know which one.  I've tried 
setting everything to not be focusable, but I must be missing something. 

Isn't there some way that the top level component can always see key 
events for it or any sub component?  That's all I really need.  I just 
want all events to go to my top level component.  

Thanks.

Another possibility is a way to set mnemonics to answer to Ctrl-whatever 
instead of alt-whatever. 

Thanks.

Might this be relevant: "In general, pressing the Tab key moves focus 
through the major components; Shift-Tab moves through the components in 
the reverse direction. Control-Tab and Control-Shift-Tab work in a 
similar fashion and are necessary when keyboard focus is in an element 
that accepts tabs, such as a text area."

This wasn't the problem.  My initial attempts to get this to work were 
correct, but I missed a key step.  Basically I called setFocusable(false) 
on each of the components in my applet.  This included a toolbar.  What I 
didn't do is to call setFocusable(false) on each of the buttons in the 
toolbar.  Once I did this, the app worked as expected.  

Thanks for your suggestion.

You can do that recursively, you know...

Good point.  That would probably be the way to go.  I'm not getting paid 
anymore for this project, but in the future that's probably how I'll do 
it.  

Thanks.
