[XaraXtreme-dev] Keypress handling

[Luke Hart <lukeh@xxxxxxxx>]

All,

It seems that having the key press handler in a window has 2 problems:

* If the window isn't present no key press handling is done (obviously). 
This happens when handling is in the Render Window and no documents are 
open. The problems we saw when I put the key handling in the view class 
are just a special case of this.
* If the window isn't the one that is actually receiving the key press, 
the key down is lost (it's sent for IM handling and never gets any 
further). This means that we can't handle key presses in the main frame.

There are 2 possible ways that this could be addressed:

1) Move back to handling the keys at the application level. This is how 
they were working before the changes to satisfy the focus handling rules 
and had been proved to work.
2) Examine wx code and see if this can be modified to behave in a manner 
closer to how we'd expect.

I'd be inclined to suggest initially going down route 1, and then 
looking at a cleaner fix later (possibly after 0.5)
