Re: Label resizing window, ellipsizing
Try setting "width-chars" property as well as "max-width-chars" property. GtkLabel apis could use a face-lift. It's possible that the default minimum width request exceeds the 10 max-width-chars which you set (which is what I assume is causing this problem).

release resource of gtk
hi everyone, I run GtkLauncher(webkit/gtk/directfb), I find gtk/directfb are not released even if gtk_widget_destroy(top_window) has been called before gtk_main() quit. I don`t find function such as gtk_term or gtk_deinit() to release gtk . How to release whole gtk resources when application quit? Thanks.

Label resizing window, ellipsizing
Hello there, I was wondering if there was a way of avoiding a label (in a notebook) to resize the window when the text in it is too big. I heard of ellipsizing, and EllipsizeMode.END seems great for me, but if I ellipsize it, it will be ellipsized even if the label is small. So, I want to ellipsize it only when it becomes too big (over X pixels), but I only seem to be able to limit it's width in chars using max_width_chars. I also tried setting my label's max_width_chars to 10, but the string could still increase a lot, so it didn't work. What do you recommend? Ideally, I would like to have a maximum width in pixels, but chars is ok too. /* Relevant code (vala) */ tab.label.max_width_chars = 10; -- David Gomes ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: error in compile gtk3 in OSX
Apple's gcc doesn't seems to have the -x option that is passed from g-ir-scan. As a workaround, I use "make V=1" to see what is executed and I copy-paste the full command excluding the "-x". After doing this I can run make again with no errors. 2011/12/6 xiaobo : > Hi, All > > I got a error when I compile gtk3 in OSX . > This is log. > > . > . > CCLD libgtk-3.la > CC queryimmodules.o > CCLD gtk-query-immodules-3.0 > GISCAN Gtk-3.0.gir > Usage: g-ir-scanner [options] sources > > g-ir-scanner: error: no such option: -x > make[4]: *** [Gtk-3.0.gir] Error 2 > make[3]: *** [all-recursive] Error 1 > make[2]: *** [all] Error 2 > make[1]: *** [all-recursive] Error 1 > make: *** [all] Error 2 > > what is g-ir-scanner ? > > I need you help, please :) > ___ > gtk-app-devel-list mailing list > gtk-app-devel-list@gnome.org > http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
GTK 3 support status
Hi, I am wondering what the status of GTK 3 is at this time with regard to bugs reported by application developers. I reported a rather serious bug (https://bugzilla.gnome.org/show_bug.cgi?id=662043) a month and a half ago, and there is still no comment from any GTK developer. The bug affects the Audacious project to the point that we will be forced to go back to using GTK 2.x if it is not resolved soon. I agree with the conclusion of another user that this is a bug "breaking [the] UI design" of GTK applications. Thank you for your attention. -- John Lindgren ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Usage of gtk_list_store_set_valuesv()
Hi list,
I'm trying to write a small app which uses a GtkTreeView to display a table.
For some reason it does not work as expected so I extracted my usage in a small
tableTest app (which a attach to this mail).
I have 10 columns and 100 rows.
Basically this is the central function:
static void populateTable(GtkTreeView *treeView) {
int i;
char data[1024];
GType types[COLUMN_COUNT];
GtkTreeViewColumn *column;
for(i = 0; i < COLUMN_COUNT; i++) {
sprintf(data, "%d", i + 1);
types[i] = G_TYPE_STRING;
column = gtk_tree_view_column_new_with_attributes(data,
gtk_cell_renderer_text_new(), "text", 0, NULL);
gtk_tree_view_append_column(GTK_TREE_VIEW(treeView), column);
}
int j;
GtkTreeIter iter;
GtkListStore *listStore = gtk_list_store_newv(COLUMN_COUNT, types);
for(i = 0; i < ROW_COUNT; i++) {
/*
GValue values[COLUMN_COUNT];
gint columnIds[COLUMN_COUNT];
*/
GValue *values = g_slice_alloc0(sizeof(GValue) * COLUMN_COUNT);
gint *columnIds = g_slice_alloc0(sizeof(gint) * COLUMN_COUNT);
memset(values, 0x0, sizeof(values));
gtk_list_store_append(listStore, &iter);
for(j = 0; j < COLUMN_COUNT; j++) {
sprintf(data, "%d", j + 1);
printf("Data=%s\n", data);
g_assert(!G_VALUE_HOLDS_STRING(&values[j]));
g_value_init(&values[j], G_TYPE_STRING);
g_value_set_string(&values[j], data);
columnIds[j] = j;
}
gtk_list_store_set_valuesv(listStore, &iter, columnIds, values,
COLUMN_COUNT);
g_slice_free1(sizeof(GValue) * COLUMN_COUNT, values);
g_slice_free1(sizeof(gint) * COLUMN_COUNT, columnIds);
}
gtk_tree_view_set_model(treeView, GTK_TREE_MODEL(listStore));
}
I expected that in each row I see
col '1' = '1' | col '2' = '2' etc...
But In my case each cell holds the value '1'
What do I wrong here?
Thanks a lot,
Antonio

Don't confuse that with limiting a widget's size, a label will request a minimum size based on it's content and configuration, it may require more width than the explicit minimum size set by the user. A widget's size can only be limited by limiting what content will be displayed inside it (for label widgets this is done using width-chars/max-width-chars in conjunction with ellipsizing/wrapping).

GTK_WIDGET_SET_SENSITIVE is not GTK_WIDGET_IS_SENSITIVE. GTK_WIDGET_SET_SENSITIVE does not exist, there has always been a function for this: gtk_widget_set_sensitive(). Also note there are two kinds of functions: the -get-/-set- kind and the -is- kind, the former for querying/setting whether the widget can be sensitive and the latter for querying whether it actually is sensitive. See the documentation. > this program works on ubuntu 11.10 which is a direct fork of > debian. i was certain it would work on my laptop whivh has the > latest debian. Ubuntu contains a newer verison of Gtk+. You cannot expect a program developed with a newer version to work with an older version unless you take care to use only functions that are present in the older version.

Use devhelp or look at the on-line reference documentation to see when a specific symbol appeared. Use gtkdoc-depscan to scan your source code for functions that are available only since a specific Gtk+ version. Use GTK_WIDGET_IS_SENSITIVE() for compatibility with older Gtk+.
