Thread: [Help] C + Gtk+

I'm getting a segmentation failure (that's the traduction from spanish tu english)

Code:

void callback_main_button_build( GtkObject *object ) {
GtkWidget *frame_build;
GtkWidget *table;
GtkWidget *button_build;
GtkWidget *text_id;
GtkWidget *text_passwd;
GtkWidget *text_name;
GtkWidget *text_place;
GtkWidget *text_keyname;
GtkWidget *label_id;
GtkWidget *label_passwd;
GtkWidget *label_name;
GtkWidget *label_place;
GtkWidget *label_keyname;

table = gtk_table_new(6, 2, FALSE);
label_id = gtk_label_new("ID:");
label_passwd = gtk_label_new("Passwd:");
label_name = gtk_label_new("Name:");
label_place = gtk_label_new("Place:");
label_keyname = gtk_label_new("Keyname:");
text_id = gtk_entry_new();
text_passwd = gtk_entry_new();
text_name = gtk_entry_new();
text_place = gtk_entry_new();
text_keyname = gtk_entry_new();
button_build = gtk_button_new_with_label ("Build");
frame_build = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_default_size(GTK_WINDOW(frame_build), 250, 200);
gtk_window_set_title(GTK_WINDOW(frame_build), "Build Card");
gtk_container_add(GTK_CONTAINER(frame_build), table);
gtk_table_attach_defaults(GTK_TABLE(table), label_id, 0, 1, 0, 1);
gtk_table_attach_defaults(GTK_TABLE(table), text_id, 1, 2, 0, 1);
gtk_table_attach_defaults(GTK_TABLE(table), label_place, 0, 1, 1, 2);
gtk_table_attach_defaults(GTK_TABLE(table), text_place, 1, 2, 1, 2);
gtk_table_attach_defaults(GTK_TABLE(table), label_name, 0, 1, 2, 3);
gtk_table_attach_defaults(GTK_TABLE(table), text_name, 1, 2, 2, 3);
gtk_table_attach_defaults(GTK_TABLE(table), label_passwd, 0, 1, 3, 4);
gtk_table_attach_defaults(GTK_TABLE(table), text_passwd, 1, 2, 3, 4);
gtk_table_attach_defaults(GTK_TABLE(table), label_keyname, 0, 1, 4, 5);
gtk_table_attach_defaults(GTK_TABLE(table), text_keyname, 1, 2, 4, 5);
gtk_table_attach_defaults(GTK_TABLE(table), button_build, 0, 1, 5, 6);
gtk_widget_show_all(frame_build);
}

I'm calling this form with this code

Code:

gtk_signal_connect(GTK_OBJECT(menu_main_file_build), "activate", GTK_SIGNAL_FUNC(callback_main_button_build), NULL);

It's really strange cause i did it with another form and it worked but, the last two aren't working..
Thanks..

I had a brief look over this and I cant see anything wrong with it, but then I dont have all that much experience wutrh gtk+. gtk_signal_connect is deprecated tho so you might want to look at using g_signal_connect instead. Also, do try runnning it with a debugger, or at least be descriptive about your problem. I have no idea what you mean by "the last two aren't working" Last two what

The last two windows I've created don't work, only one works, thats why I said that, and g_signal_connect is not interpreted by my compiler, so I used gtk_signal_connect that was on another manual..

I was working from a tutorial that used gtk_signal_connect, a lot of the gtk stuff on the net is outdated. You might be best off downloading the reference manual: http://library.gnome.org/devel/gtk/

If you strip out all the content so you're basically left with an empty window will that work? Trial and error can help find where your problem is. Also, have you tried running it in debug (-g)?

I didn't knew, but i was compiling with the old gtk+ library, now i have compiled it with gtk+-2.0 and I'm getting this error..

(pbclient:13596): Gtk-CRITICAL **: gtk_window_set_default_size: assertion `GTK_IS_WINDOW (window)' failed

(pbclient:13596): Gtk-CRITICAL **: gtk_window_set_title: assertion `GTK_IS_WINDOW (window)' failed

(pbclient:13596): Gtk-CRITICAL **: gtk_container_add: assertion `GTK_IS_CONTAINER (container)' failed

(pbclient:13596): Gtk-CRITICAL **: gtk_widget_show_all: assertion `GTK_IS_WIDGET (widget)' failed

It's like failing on creating this windows, but in another one I have, there are no errors..

I don't know much about GTK. Other than running the code through a debugger, a gtk-related forum may help you more (http://www.gtkforums.com/ as an example). That's just my two cents.
