Okay, you'll have to help me here -- why do you want to use a deadkey in
your specific application? Normally deadkeys are taken care of at the
underlying X level, no?

  When a keypress comes I do:
   1. check it's a keypress event
   2. check if keyval  0xff00 == 0xff00, if it's that, - contrrol key
   3. if not control key:
   4.  oldstr = oldstr +  unichar(gtk.gdk.keyval_to_unicode( keyval ))

[snip]

 Is there some kind of value that I can keep, to process next keypress
 with, in order to apply the char modification?

You can do all this manually by storing something like self._last_key
(you could even store it as widget.set_data(_last_key, XXX) and then
blocking insert_text (and setting it yourself) if you really wanted.

Take care,

[pygtk] help: how to build text from keypress and dead/compose keys ?

[alejandro david weil]

Hi!

 I hooked key_press event.. and all was ok until I wanted to 'handle' 
deadkeys .. well actually.. the deadkey event comes as a keypress.

 But I can't handle it, I could save it for later use.. but still don't know
how can I use that when other key comes.

 When a keypress comes I do:
1. check it's a keypress event
2. check if keyval  0xff00 == 0xff00, if it's that, - contrrol key
3. if not control key:
4.  oldstr = oldstr +  unichar(gtk.gdk.keyval_to_unicode( keyval ))

Well I must check that keyval_to_unicode doesn't return 0L.

But, is keyval_to_unicode the function that I should call? 

I saw that there are some gtk_im_context methods/classes.. 
are them for this kind of things? (i don't found information about
that functions)..

Is there some kind of value that I can keep, to process next keypress
with, in order to apply the char modification?

Thanks in advance!
