intercepting key release in an entry

[Yann Leydier <yann leydier info>]

Hi,

I have a set of entries and I want the following behaviour: when the 
user types <space>, the focus passes to the next entry, when the user 
types <shift-space> a regular space is inserted in the entry.

As the insert_text event does not allow to check key modifiers, I tried 
to connect to the key_release_event (I added it to the event mask) with 
after=false and returning true when <space> is pressed to prevent the 
signal from being dispatched any further, but the space is still 
inserted in the entry.

Is there any way to do this?

Thanks,
yann
