[news.eclipse.tools] Problem with Canvas widget in SWT

[lk@xxxxxxxxxxx (Lawrence Kesteloot)]

(This is stand-alone SWT on Windows.)

I've got a Shell widget which contains a Combo box and a Canvas.
I (illegally) pass the Canvas's HWND to a bit of native code that
draws into it.  All this works fine, and the native code even
gets the mouse events, redraw events, etc.  The problem is that
it doesn't get the keyboard events.

I don't know enough about Windows event handling to know what's
going on, but I suspect it has to do with the Shell not passing
on keyboard events because they're being redirected to the Combo
box (which has input focus).  How do I tell either the Shell or
the Canvas that keystrokes are allowed to be received by the
Canvas?

(The goal is to use a text editor written in C as an editor
plugin in Eclipse.)
