GtkTreeRowReferences and ¿signal 155?
Hi all,
I'm building an app with a TreeView with the selection mode set to
multiple. When i have to delete data from the tree view, i get a list of
selection with gtk_tree_selection_get_selected them i transform this
list into another list with GtkTreeRowReferences in it.
The deletion of the data works, but just after delete some element i get
this error message:
GLib-GObject-WARNING **: gsignal.c:2133: signal id `155' is invalid for
instance `0x8072eb8'
Does anybody knows what is this? I didn't connect any signal to the
RowReference. Here's goes part of the code:
/* act is a GList of GtkTreeRowReferences */
while (act != NULL)
{
if (gtk_tree_row_reference_valid ((GtkTreeRowReference*)
act-data))
{
path = gtk_tree_row_reference_get_path
((GtkTreeRowReference*) act-data);
gtk_tree_row_reference_free ((GtkTreeRowReference*)
act-data); /* Without this the error keep appearing */
if (path != NULL)
{
gtk_tree_model_get_iter (model, iter, path);
gtk_tree_model_get (model, iter, BRAND_ID_COLUMN,
brandid, -1);
/* Updates DB */
res = db_brand_delete (brandid);
if (res == SQLITE_DONE)
{
/* Updates model */
gtk_list_store_remove (GTK_LIST_STORE (model),
iter);
}
}
}
act = g_list_next (act);
}
I'm using Gtk+-2.10.6 and Glib 2.12.4.
Thanks in advance, Matias.

Re: GTK table insert row
Guy Rouillier escribió: Razvan wrote: Hi there I have the following problem: I have a dynamic created table and at a moment I want to insert a whole row into the table but I dont know how to do it. I dont want to re-create the entire table. Is there any possibilies to do such thing ? Any help or suggestions are apreciated. You don't provide much to go on. Which Gtk widget are you using - GtkTable or GtkTreeView with a backing list store? If what you're looking for is to insert a widget into a whole row what you can do is this: gtk_table_attach (GTK_TABLE (table), widget, 0, LAST_TABLE_COLUMN, 0 , 1, GTK_FILL | GTK_EXPAND, 0, 0, 0); This way the widget will be inserted from 0 to the last column. The GTK_FILL and GTK_EXPAND flags are specified so the widget expands to the full width of the table. Hope that's what you're looking for.

SpinButton and Decimal separator
Hi all, I'm using a spin button to enter float numbers. The default locale has the ',' as decimal separator, but i want to also use the '.' as the decimal separator.

Gettext
Hi all!
Yes, I know it's not a GTK question but i couldn't find an answer to my
problem.
After building my application (if it helps, it uses gtk), i use gettext
for translating it, and, in linux it works just fine. But, talking about
windows, well .. it doesn't..
Note: Gtk Widgets DO translate, but the my own text doesn't.
This is what i do:
..
#include gtk/gtk/h
#include libintl.h
..
#define PACKAGE xiliunsystem
#define LOCALEDIR po
..
void nls_init (void)
{
/* SHOULD I CALL gtk_set_locales(), WHERE? */
setlocale (LC_ALL, );
bindtextdomain (PACKAGE, LOCALEDIR);
textdomain (PACKAGE);
bind_textdomain_codeset (PACKAGE, UTF-8);
}
int main ( ... )
{
nls_init ();
gtk_init (argc, argv);
return 0;
}
The message catalogs are in a subfolder in the main app dir called po
which looks something like this:
myAppDir/po/es/LC_MESSAGES/
In there there's a myapp.mo file compile with msgfmt.EXE
Does anybody knows what's wrong or run into this problem?
Please, Thanks and I'm sorry I'm sorry I'm sorry I'm sorry I'm sorry i
konw it's not a gtk question.

A wild guess - maybe #include glib-i18n.h ?
also, is all that stuff in nls_init() really needed ?

Thanks for answering, really.
About the myapp.mo to xiliunsystem.mo, well it is called
xiliunsystem.mo but i was trying towrite a more anonymous mail :P
And yes, the application Working Dir is ok.
Thanks anyway, i'll try that and get back to you soon.
Well.. about glib-i18n.h, i couldn't find it in my system. So i googled
it and only two results appeared which makes me think that's not the
problem. Another thing about my app is that the intl.h.

Well i found out what was happening. For initializing the gettext macros
i used the archive that glades generates under the name of support.h
with ONLY the gettext macros thought i did not use glade.
I don not compile the traditional way (./configure make) when trying to
port to windows because of many many problems but i compile the
traditional traditional and more traditional way:
mingw-gcc CFLAGS ...SOURCES MANYLIBS(godbless pkg-config)
Because of this the ENABLE_NLS enviroment variable wasn't set when i try
to build the sources.
Hope it helps someone. To that someone: LEARN TO USE AUTOCONF because i
didn't and it can make you wish the computer explotes. Thanks to all
again, good bye!

Problem with the stamp in gtktreeiter
Hi I'm trying to make a widget that works just like the address bar in epiphany (a combo box with completion) The widget i'm workin on is a composite widget that uses GtkComboBoxEntry and GtkEntryCompletion. This widget has a unique gtktreemodel that both, GtkComboBoxEntry and GtkEntryCompletion use, but when i try to set the active iter to the combo box based on the match-selected signal from the GtkEntryCompletion it tells me that the stamp of the iter is invalid. How can i fix this? If anyone knows where can i get a similar widget, please let me know Thanks in advance, matias. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Gtk Curves

THANKS! ** hello, i'm trying to make a curve based on some values passing a float array to a GtkCurve: gtk_curve_set_vector ( GTK_CURVE (income_curve), length, array) This results in well.. not a curve, but a number of straight lines like this: 4 3 2 1 (hope you understand, i just don't know how to explain it let's say i'm looking for a continuous curve) Changing the curve type does not help at all (segmentation fault). Do you know how to make it work? or.. Do you know some other library that let's me draw a curve based on a limited number of floats? Thanks in advance.

Re: Reference Counting
Thanks for answering. So basically... (About the g_object_weak_ref) GDate *date = g_date_new_dmy (1,1,2006); GtkEntry *entry = gtk_entry_new (); g_object_weak_ref (G_OBJECT (entry), (GWeakNotify) g_date_free, date); After doing this, before entry is freed gtk would call g_date_free and free date. Am i wrong? I tried this with a GWeakNotify function that just prints something, but it didn't seem to work. There's something else, i want to add more reference to other dates, to new ones, if i want them to be week referenced i'd have to call g_object_add_weak_pointer ( http://developer.gnome.org/doc/API/2.0/gobject/gobject-The-Base-Object-Type.html#GObjectG_OBJECT (entry), another_date); or g_object_weak_ref again? Thanks anyway!

See: http://developer.gnome.org/doc/API/2.0/gobject/gobject-The-Base-Object-Type.html *- When reference count starts? I read somewhere that it starts when you add the widget into a container, is it always this way??? Eg:* Reference counting starts when an object is created. In your example: GtkWidget *entry = gtk_entry_new (); After this statement, there is one reference to the entry. When gtk_container_add is invoked, it takes over ownership of this reference. That is when the container is destroyed, g_object_unref is invoked on the entry. So one needs to invoke destroy only on the root widget (typically). //*No reference counting on GtkEntry*// GtkWidget *entry = gtk_entry_new (); //*Reference counting starts here *// gtk_container_add (GTK_CONTAINER (window), entry);/ /* Another doubt: in this case, reference couting starts with 1 or 2? */ / -* If i get a string from a GtkTreeModel, it gives me a copy or the actual pointer to the data? If you're using the get_value method on the iterator, the object is copied into the GValue supplied. Typically this gives you just a reference, and invoking g_value_unset results in just decrementing the reference count. But what exactly happens during copying depends on your object.

Re: Search for a widget that can completion and option_box
I had the same problem a few weeks ago. I modified a function i found in
a webpage (put koders in google), this is the fuction:
/*
* This function returns a GtkComboBox with a GtkEntryCompletion inside
instead a GtkEntry
* it needs a GtkTreeModel containing the data and the column used to
search
*/
GtkWidget *create_combo_box_entry (GtkTreeModel *model, int text_column) {
GtkWidget *categories; /*GtkComboBox*/
GObject *completion; /*GtkEntryCompletion*/
categories = gtk_combo_box_entry_new_with_model (model, text_column);
completion = G_OBJECT( gtk_entry_completion_new () );
/* There's a gtkentry inside the combobox, all we need to do is set
the completion for it*/
gtk_entry_set_completion ( GTK_ENTRY( gtk_bin_get_child( GTK_BIN(
categories ) ) ), GTK_ENTRY_COMPLETION(completion) );
gtk_entry_completion_set_model (GTK_ENTRY_COMPLETION(completion),
gtk_combo_box_get_model(GTK_COMBO_BOX(categories)));
gtk_entry_completion_set_text_column(
GTK_ENTRY_COMPLETION(completion), text_column );
gtk_entry_completion_set_minimum_key_length (GTK_ENTRY_COMPLETION
(completion), 2);
gtk_entry_completion_set_inline_completion (GTK_ENTRY_COMPLETION
(completion), FALSE);
/* To keep the the widgets syncronized */
g_signal_connect( GTK_ENTRY_COMPLETION(completion),
match-selected, (GCallback) update_cb, categories );
return categories;
}
That's it, it worked for me. Oh, excuse my bad english too. :P

Hi,
excuse my bad english! We are saerching for a widget that combined the
gtk_entry_completion with gtk_combo_box_entry, but we have no success.
An example is the url widget in firefox. It has more than one

completion and the possibility explicit popup the tree_view.
In all gtk extra widget sets (libsexy, libview, ..) I can't find this
entry typ. In mozilla I can't find the sources.
Have you looked at the URL widget in epiphany?
