Hello and thanks for the answers for both Daniel and Paul.
I chose to use the signal blocking/unblocking method.
I now add a new data attribute "value-changed-signal" to the spin
button. The data value contains the signal handler id which I can later
read and use. The code looks like this:
adj = gtk.Adjustment(orig_width, 1, orig_width, 1, 50, 0)
self.width_spin = gtk.SpinButton(adj, climb_rate=0.0, digits=0)
self.width_spin.show()
self.width_spin.set_numeric(True)
# Save the signal handler to "value-changed-signal" attribute.
self.width_spin.set_data("value-changed-signal",
self.width_spin.connect("value-changed",
self.image_size_changed_callback, None))
and later in...
def some_function()
# Block signals
self.width_spin.handler_block(self.width_spin.get_data("value-changed-signal"))
self.width_spin.set_value(some_value)
# Unblock signals
self.width_spin.handler_unblock(self.width_spin.get_data("value-changed-signal"))
Ok, thanks for now :-)

I guess you can always do:
self.width_spin.freeze_child_notify()
self.width_spin.set_value(some_value)
self.width_spin.thaw_child_notify()

Subject: [pygtk] Setting value of gtk.SpinButton without triggering
the "value-changed" event.
Hello,
I need to change the self.width_spin (gtk.SpinButton) value, but in
some cases I do not want the changed event to fire. How do I set the
value? This is my code:
adj = gtk.Adjustment(orig_width, 1, orig_width, 1, 50, 0)
self.width_spin = gtk.SpinButton(adj, climb_rate=0.0, digits=0)
self.width_spin.show()
self.width_spin.set_numeric(True)
self.width_spin.connect(*"value-changed"*,
self.image_size_changed_callback, "width")
hbox1.pack_start(self.width_spin, False, False, 0)
This call will trigger the *"value-changed"* event so I want to avoid it.
self.width_spin.set_value(some_value)
gtk.SpinButton is derived from gtk.Entry, so if I could grab the entry
field from gtk.SpinButton so it may be possible to write:
entry.set_data("value", some_value)
Do you know how to do this right?
Am writing a filter/resize/and scale plugin in Python for my
screendump program http://bildr.no/view/291282. Screendump is written
in GTK and c.
TIA
