Can you give me a quick code example?
If you just want to do something special for a particular widget, then
using the key_press_event signal is the correct aproach. You look at the
attributes of the event object to see which key was pressed. Return TRUE
if you handled the event yourself, and FALSE otherwise.
Okay, that makes a lot of sense, but I"m having problems wrapping the
event trigger. (sp_sendtext is a gtktext widget)
ta = widgets.get_widget('sp_sendtext')
ta.signal_connect('key_press_event',sendkey)
Which triggers
def sendkey():
print "Key pressed! "
return FALSE
But I get:
[shevett@cheetah]:~/python/spanker/proj1$ ./spanker.py
Traceback (innermost last):
File "/usr/local/lib/python1.5/site-packages/gtk.py", line 125, in
__call__
ret = apply(self.func, a)
TypeError: no arguments expected
Wha'd i do wrong?
Also, could you point me to the structure of an event object?

Etc. I understand that it's an GdkEventKey struct. There's a lot of
structures returned from GTK. I understand there are methods associated
with Objects that come back (ala a 'set_text' associated with a GtkEntry
field, etc).
But how do I retrieve values from the structure? ala, 'gint' is within
the structure. How do I get that value, with an explicit
get_gint() method associated with the object?
Ahem. In the above snippet of doc, 'gint' is a type, not a member. ;o)
The python mappings are very easy to use: the keyevent parameter you get
is a python object with attributes that match the names of the C structure
members. If you want to react on a ^C, for example, you can do something
like:
import GDK
def keyevent_handler(widget,keyevent):
if keyevent.keyval=GDK.C and keyevent.state=GDK.CONTROL_MASK:
# do something here
pass
Does this answer your question?

Hi folks. I'm writing a GTK app using libglade in Python. So far thinks are going okay, but I'm having some difficulty connecting accelerators and trapping signals from them.

You can't just invent signal names like that. Accelerators have to activate an existing signal on an object. If you just want to catch some other key presses on a particular widget, then connect to its key_press_event signal, and handle the key presses there. Thanks!
