[news.eclipse.platform.swt] keylistener doesn't work

[jeanvalery@xxxxxxxxxxx (jeanvalery)]

Hi!
Here's my problem.
I've got a main class that launches a display and a shell (MainShell).
It call a class (ScreenClass) that creates a second shell (SecondShell) to 
draw a screen (a set of composites).
(The MainShell is not displayed, but it has to exist for tests and other 
things like that... I create MainShell but I make it unvisible and do not 
pack/open it!)
The shell "SecondShell" is public in the class "ScreenClass".

I tried to apply a keylistener on SeconShell from the main class, but it 
didn't work. I tried to apply the keylistener on SecondShell in 
ScreenClass, but it failed too.

However, when i apply the keylistener on MainShell in the main class, it 
works, if I pack/open MainShell and make it visible. What's more, 
MainShell must be focused so that the keylistener works.

But i don't want MainShell to be visible, nor it has the focus.

I want to apply a keyListener on SecondShell, whatever way I do it.

Does anyone got any idea?

Thanks a lot.

jean.
