Re: Cell Renderer Combo Callback
Hello, Le 12/09/2007, dhk [EMAIL PROTECTED] a écrit : I have a combo render in a treeview and I can't get the callback to set the value once it's selected. I didn't test the code you gave, so can't be sure, but I suggest to remove the « text, Stock, » property from the combo rendrer. g_object_set(G_OBJECT(renderer), model, ls_combo, text-column, 0, text, Stock, has-entry, FALSE, editable, TRUE, NULL); In my own code, I also create my column with the text attribute pointing to the right column id of my model: col = gtk_tree_view_column_new_with_attributes(ItemType, renderer, text, 0, NULL); That's the only differences I can figure out.

Re: Cell Renderer Combo Callback
Thanks, but it still doesn't work. I think the problem is in getting the iter for the list store which is used in the combo render or it might be working and just not getting rendered to be visible. I'm fairly sure the problem is in the callback.

Animation with GTK+
Hello, I'm totally new to the GUI application development in Linux X11. I was mostly involved in embedded non-graphical development. Now I need to create GUI interface application using GTK+. Could you advise me the best way to create animation of a rotating object in GTK window? This object is going to be a picture of a device rotating in sync with a real hardware device. Which library/extension I can use? Thank you. Regards, Konstantyn ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

I think the problem is in getting the iter for the list store which is used in the combo render or it might be working and just not getting rendered to be visible. I'm fairly sure the problem is in the callback. Ok, I test your code in some of mine to see what happen. The two points I spoke about are relevant and should be applied. Because, with the first (text, Stock) Stock is always drawn instead of the choice. With the second, nothing is printed in the cell. But, in the callback, going through a GtkTreePath (think to free it after use) doesn't work (don't know why exactly). In my experience, I use instead directly: valid = gtk_tree_model_get_iter_from_string(GTK_TREE_MODEL(list), iter, path); to get the iter from the string 'path'. With these three points, it should work. Damien. PS: if you want a default value for your combo, like Stock, just add Stock in your model. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Animation with GTK+
If you have an animated gif, you can use GtkImage. If you need to actually sync it with something external, you can use GdkPixbufAnimation and GdkPixbufAnimationIter: http://library.gnome.org/devel/gtk/unstable/GtkImage.html http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-animation.html - Original Message From: Prokopenko, Konstantyn [EMAIL PROTECTED] To: gtk-app-devel-list@gnome.org Sent: Wednesday, September 12, 2007 9:38:18 AM Subject: Animation with GTK+ Hello, I'm totally new to the GUI application development in Linux X11.

Changing a previously created GtkImage
I have created an image from a file using
image1 = gtk_image_new_from_file(pictures/Empty.gif);
gtk_widget_set_name (image1, image1);
and displalyed it using:
gtk_widget_show(image1);
gtk_box_pack_start(GTK_BOX (hbox1), image1, TRUE, TRUE, 0);
and that works fine. The image is correctly displayed where I want it.
Later, when a particular event happens (right now I have assigned it to a
button press), I want to change the image to the image in the file
pictures/Full.gif (which is exactly the same size as Empty.gif). To do
that, I did the following:
void on_button1_pressed (GtkButton *button, gpointer user_data)
{
GtkWidget *imageptr;
imageptr = lookup_widget(GTK_WIDGET(button), image1);
if(imageptr != NULL)
{
gtk_image_set_from_file(GTK_IMAGE(imageptr), pictures/Full.gif);
}
else
fprintf(stderr, image1 not found\n);
}
When I press the button, the image is replaced by a broken image icon, not
the new image. What am I doing wrong? I am obviously getting the correct
widget with the lookup_widget call, since the image changed. The file
Empty.gif and the file Full.gif are in the same directory, and when I
change the gtk_image_new_from_file() call to load the Full.gif file, that
works fine as well, so I know the file is there and readable. I just don't
understand why it didn't change to the new image.
Thanks,
T

Can't the working directory change meanwhile? Paths such as
pictures/Full.gif seem quite fragile to me.
1) Try g_file_test() to check whether pictures/Full.gif
exists as the time on_button1_pressed() is called.
2) Try to load the image with gdk_pixbuf_load() and look at
the error your obtain.

The topic of this list is the development of Gtk+, not with Gtk+. Direct questions like this to gtk-list. The short answer is: No, but you have to *free* it. See the documentation of g_strconcat(). And you should use g_build_filename(). Yeti -- http://gwyddion.net/ ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
