Controlling a widget from an other

[kalap kabat <kalap kabat freemail hu>]

Hi,

I have a simple window with a text entry and a treeview below 
it. 

The text entry has the focus, so the user can type in it. I'd like 
to allow the user to scroll the treeview without having to switch 
the keyboard focus manually to the treeview.

So if the user presses up/down/page up/down when being in 
the text entry, I'd like the treeview to properly react to these 
keypresses.

How can I do it?

I see two alternatives:

- Catch the keypress in the text entry and invoke the 
appropriate functions of the treeview for scrolling. This does 
not seem viable, since the scrolling functions are not exposed 
for the treeview.

- When up/down/etc is pressed then the keypress should be 
sent to treeview somehow by focusing it temporarily and 
generating a new keypress event? Is it possible? 

Or is there any other way?


Thanks in advance.
