Re: Setting value of gtk.SpinButton without triggering the "value-changed" event.

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 :-)

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

Hello,

I'm looking for MacOS user to test my Papywizard software. It is written
in PyGTK, and only use pyserial and pybluez additional modules. I works
under Nokia/maemo, Windows, and Openmoko - not fully tested -
plateforms. So it should works fine under MacOS; it may just need some
minor adjustements regarding files paths.

The sources are here:

   http://trac.gbiloba.org/papywizard/browser/trunk

(click on the link at the bottom of the page to get a zip archive).

If all works fine, I would also like to make a MacOS package. Does
anybody have links to documentation to do that?

Thanks,

Re: Help with gtk.Menu.popup

Thanks for your help.

My problem is this:

self.icon = gtk.status_icon_new_from_stock(gtk.STOCK_REFRESH)
self.icon.connect('popup-menu', self.onRightClick)
self.icon.connect('activate', self.onLeftClick)

In onRightClick function the signal 'popup-menu' has activate_time param
but in onLeftClick function the signal 'activate' has not it.

http://www.pygtk.org/docs/pygtk/class-gtkstatusicon.html

I want to open a menu in a status_icon with the left button of my mouse.

Thanks.

store ListStore

Hi,
I need to save the values of a ListStore in a file, but apparently that is not that easy.
I tried with pickle, but that didn't work.
Is it possible at all?

For PyGtk, the pygtk-demo program (that should be installed with PyGtk) 
contains some great examples. See http://mysql-python.sourceforge.net/ 
for more information about using MySQL in Python.

Re: DrawingArea user feedback

On lundi 17 novembre 2008, Frédéric wrote:

> GtkWarning: gtk_widget_set_events: assertion `!GTK_WIDGET_REALIZED
> (widget)' failed

As far as I understand, this assertion is raised because the set_events() 
method should be called *after* the widget is realized, ie after it is 
drawn on the screen.

But my drawing area is part of a dialog, and this dialog is opened from the 
main window as a modal dialog, calling its run() methog. Once it enters in 
its main loop, I can't do anything more, so I can't call the set_events() 
method!

I don't understand why GTK+ is so complicated for such simple things... Why 
signals are not enabled by default? As long as there are no callback, I 
don't see what could happen. In fact, I think that low-level stuffs are 
not object-oriented, and are very difficult to integrate in an 
object-oriented application.

Any idea to solve my problem?

right way to share GOptionContext pointer from pygobject

I've done a patch for gnome-python to add GOption support[1].  Using the
existing GOptionContext wrapper in pygobject this is possible but access
to the wrapped GOptionContext pointer is required to pass to
gnome_program_init.

I'd be grateful to know whether cobjects are a good way of doing this
per http://bugzilla.gnome.org/attachment.cgi?id=117380&action=view -
