Re: Get column no. of edited cell.
Another possibility would be to use g_object_set_data to give the renderer a column number, and g_object_get_data in the handler.

Ctrl key, event state value, XIM vs IBus
Hi, I have a program that connects to the key pressed event. I am getting different event-state value for Ctrl, depending on the input method. - XIM gives 4 - IBus gives 33554436 is this how it is meant to be? How should I process it? GDK_CONTROL_MASK catches only the XIM value (Same for Alt) ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Noticed the [out] in path and focus column? That means you have to
pass the pointers to a (GtkTreeViewColumn *) variable and a
(GtkTreePath *) variable, instead of passing a (GtkTreeViewColumn **)
variable and a (GtkTreePath **) variable.
You may do something like this then:
GtkTreeViewColumn *focus_column;
GtkTreePath *tree_path;
gtk_tree_view_get_cursor ( detect_object ( DataDisplay,
build_object ), tree_path, focus_column );
Now focus_column and tree_path contains the currently focused column
and path to its row, respectively.
Yes, now it works. Thanks!

since this particular event edited (GtkCellRender) is triggered
after the editing has finished. As a result, I get -1 with
gtk_tree_view_column_get_sort_column_id (focus_column).
So I've tried out your original technique, but I'm having some issues
there --
I'm comparing the passed over GtkCellRenderer * with all renderers as
such --
while ( mod_renderer != *(renderer + i) )
i++;
Where mod_renderer is the passed over GtkCellRenderer and renderer is --
GtkCellRenderer **renderer;
and allocated memory via --
GtkCellRenderer **renderer = g_malloc (sizeof (GtkCellRenderer*) * 2);
renderer[0] = gtk_cell_renderer_text_new ();
renderer[1] = gtk_cell_renderer_text_new ();
I'm getting sefault in the while loop.
Your comparing a GtkCellRenderer and a GtkCellRendererText here. Try
casting like this:
while (GTK_CELL_RENDERER (mod_renderer) != GTK_CELL_RENDERER (renderer[i]))
i++;
Or just store them as GtkCellRendererText:
GtkCellRendererText **renderer = g_malloc (sizeof (GtkCellRendererText*)
* 2);
renderer[0] = gtk_cell_renderer_text_new ();
renderer[1] = gtk_cell_renderer_text_new ();
But still, this is quite dangerous, since mod_renderer may really not in
renderer. You may use if/else blocks:
/* mod_renderer and renderer[i] should be GtkCellRendererText */
if (mod_renderer == renderer[0])
{
/* renderer[0] edited */
}
else if (mod_renderer == renderer[1])
{
/* renderer[1] edited */
}
Though usually when I want to do something like this, I would connect to
each cell renderer, with each one have their own callback.
Something like this:
renderer1 = gtk_cell_renderer_text_new ();
g_signal_connect (renderer1, edited, on_renderer1_edited, my_data);
renderer2 = gtk_cell_renderer_text_new ();
g_signal_connect (renderer2, edited, on_renderer2_edited, my_data);
Then I'll just do what I need to do inside the two callbacks.

GtkBox vs GtkGrid
Am I missing something? If I use GtkBox it seems that once I add a child I can't get access to it's address any more (GtkWidget *) So if I create a box with some things in it in glade I really can't do much with them. (Other than giving them specific names and using the builder object to look them up) GtkGrid seems to have more functions... maybe that would be better to use... tom ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
