[PyGTK] forbid focus of TreeView columns
Hi all,
I'm building a PyGTK interface in which I would like that no widget
would be able to get the focus (and so to be activated by pressing the
Return key). For this purpose, for each widget, I do:
widget.set_property("can-focus", gtk.FALSE)
My problem is a TreeView which has a clickable column, it get the
default focus and I did not find how to forbid that.
I tried:
def focus (widget, *args) :
try :
widget.set_property("can-focus", gtk.FALSE)
except :
pass
try :
widget.set_property("can-default", gtk.FALSE)
except :
pass
win.forall(focus)
where win is my application window (I also tried on the TreeView) but it
doesn't work. :-(
I also tried with widget.unset_flags, same result. :-((
If I choose another widget and give it the default focus
(widget.grab_default and widget.grab_focus) it's OK until I click on the
column which then keeps the focus. :-(((
I'm sure I could capture the Return key but I don't want to have this
dashed line around the focused widget...
I think that this column has somewhere an associated widget but I could
not find it anywhere (and neither could win.forall).
I'm using PyGTK-2.0.0 and cannot use another version.
Thanks in advance for any idea!

[PyGTK] Resizing a HandleBox
Hi all, I'm using PyGTK-2.0.0, when I detach a HandleBox, the resizing of the newly created window is broken: it can be resized but it's content (the HandleBox and its child) is not affected at all and is not resized. Does any one have a solytion to this problem? Thanks in advance! Franck -- http://mail.python.org/mailman/listinfo/python-list
Re: Setting sizes of widgets (PyGTK)

I have the following code and I would like to know how to set the

Your button is stretched horizontally because there is nothing to put
around it in order to fill the space. Try to embed it into a HBox,
surrounded by empty labels :
import pygtk, gtk
class Greeter:
def __init__(self):
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.box = gtk.VBox()
self.window.add(self.box)
self.label = gtk.Label("Please enter your name in the box
below:")
self.namebox = gtk.Entry(12)
self.button = gtk.Button("Greet Me!")
self.output = gtk.Label("Your output will appear here.")
hbox = gtk.HBox()
self.box.pack_start(self.label, False, False, 2)
self.box.pack_start(self.namebox, False, False, 2)
hbox.add(gtk.Label())
hbox.pack_start(self.button, False, False, 2)
hbox.add(gtk.Label())
self.box.pack_start(hbox, False, False, 2)
self.box.pack_start(self.output, False, False, 2)
self.window.show_all()
def main(self):
gtk.main()
a = Greeter()
a.main()

The problem of anonymity with decorators
Dear all,
I would like to work around the "anonymizing" effect of decorators when
an exception is raised in the wrapped function. Let's consider the
following example:
def int_result (fun) :
def wrapped (*largs, **kwargs) :
result = fun(*largs, **kwargs)
if not isinstance(result, int) :
raise TypeError, "should return int"
return result
return wrapped
@int_result
def add (a, b) :
return a+b
print add(1, 2)
print add("foo", "bar")
As expected, the last line results in raising TypeError:
Traceback (most recent call last):
File "wrapping.py", line 14, in ?
print add("foo", "bar")
File "wrapping.py", line 5, in wrapped
raise TypeError, "should return int"
TypeError: should return int
My problem is that the errors comes from a function named "wrapped"
while I'd prefer to see here the name of the wrapped function. Indeed,
the code above is only a stripped down sample code but in my
application, I'll have a lot of functions, all wrapped the same way. So
I'd prefer a traceback like:
Traceback (most recent call last):
File "wrapping.py", line 14, in ?
print add("foo", "bar")
File "wrapping.py", line 8, in add (wrapped)
@int_result
TypeError: should return int
Where the exception seems to come from the point where add "was"
wrapped, instead of from the inside of the wrapper.
I tried to change wrapper.__name__ and wrapper.func_name but it does not
change the traceback, and wrapper.func_code.co_name is read-only. I also
tried, unsuccessfully, to rename functions with:
import new
def rename (fun, name) :
return new.function(fun.func_code, {}, name)
So, my questions:
- can I change a function name so that it affects the traceback when an
exception is raised in the function?
- is there some special trick to raise an exception making it, in
appearance, coming from somewhere else?
Thanks in advance for any answer.
Regards,
Franck

I do it using DBus/Hal, for instance:
###
import dbus
system_bus = dbus.SystemBus()
hal_manager_obj = system_bus.get_object('org.freedesktop.Hal',
'/org/freedesktop/Hal/Manager')
hal_manager = dbus.Interface(hal_manager_obj,
'org.freedesktop.Hal.Manager')
for udi in hal_manager.FindDeviceByCapability("net") :
obj = system_bus.get_object("org.freedesktop.Hal", udi)
dev = dbus.Interface(obj, 'org.freedesktop.Hal.Device')
print dev.GetProperty("net.interface"),
print dev.GetProperty("net.address")
