Reading keyboard state without keylistener ??

[axel.kowald]

Hi everybody,

I would like to read the current keyboard state (is button X pressed)
without a keylistener.
The problem is that I need to recognize a keypress in my java
application even if the application is not the foreground window and
has no keyboard focus.

My application runs in a looping thread and during each cycle I want
to check the current state of the keyboard.
How can I do this?

Many thanks,

axel

I doubt it can be done in pure Java. Try JNI.

the focus hierarchy flows from Windows before it gets to your
component, you'll always get a FOCUS_LOST response because the window
that is the focus cycle root will return DEACTIVATED, no show in java
for that.
